Preface

This document comprises the engineering manual for the computer program called the National Bureau of Standards Load Determination Program

hereafter referred to as NBSLD. Presented herein are the algorithms for

the exact calculation methodology that was developed in the Thermal Engineering Section of the National Bureau of Standards to determine accurate heating and cooling loads for the thermal design of buildings. NBSLD,

which is based upon the methodologies presented in this publication, has

been available for some time for the purpose of evaluating various building constructions and systems. The program was originally developed as

a research tool because none of the commercially available programs had

features or the sophistication to enable the evaluation of unconventional

designs. NBSLD has been an indispensable tool for studies of numerous

HUD housing systems, constructions of the Defense Department and the General Services Administration where non-conventional design conditions

had to be evaluated.

As the existence and the capability of NBSLD became known, numerous

requests were made to NBS to release the program for public use. This

publication is in response to that request. Hopefully, engineers will

be able to adopt some of the computational schemes described in this publication to their own programs. A complete Fortran program is attached,

although NBS does not claim that the program is optimum from the standpoint of the computer memory allocation or computational economy. It

will take additional improvements before the program becomes optimum from

those viewpoints. The program documentation is being made available at

i
this time so engineers can use it for accurate load determination as they

seek to conserve energy through improved thermal design of buildings.

The author would appreciate receiving reader's comments with respect to

the accuracy of this text

.

It should be mentioned that some of the subroutine algorithms listed

in this publication have already been published in the well known ASHRAE

booklet entitled "Procedure for Determining Heating and Cooling Loads for

Computerized Energy Calculations". These subroutines were compiled by

the author who served as the chairman of the Subcommittee on Heating and

Cooling Load Calculations of the ASHRAE Task Group on Energy Requirements

for Heating and Cooling of Buildings. The ASHRAE publication, however,

contains several critical errors, which have been corrected for use in

this volume.

The author is greatly indebted to Dr. J. E. Hill and Mr. J. P. Barnett

for their thorough editing of the text, to Mrs. Sharon D. Crampton for

her skill and patience in typing the manuscript and to Mr. F. J. Powell

for his encouragement to produce the document.

A comprehensive computer program called NBSLD, the National Bureau

of Standards Load Determination program, has been developed at NBS to reflect the time change of the many building parameters which are pertinent

to accurate estimation of energy usage for heating and cooling. Current

status of heating and cooling load techniques is reviewed. Of general

interest are unique features of NBSLD which are not available in existing computer programs. A summary of various subroutines of NBSLD is given along with the detailed procedures for them. These subroutines constitute the recommended subroutine algorithms of the ASHRAE Task Group

on Energy Requirements. Complete Fortran listing of NBSLD and data preparation forms are given for those who wish to use the program. The NBSLD

computation is on the basis of the detailed solution of simultaneous heat

balance equations at all the interior surfaces of a room or space. Transient heat conduction through exterior walls and the interior structures

is handled by using conduction transfer functions. The use of heat balance equations, although time consuming in calculation, can avoid the

vagueness and uncertainties inherent in the more popularly used weighting

V
factor approach. In addition, it is more accurate for a specific builddesign.

1. Introduction

Numerous studies in recent years on the matter of energy shortage

lead one to believe that the U. S. demand for energy will very shortly

outstrip her power generating capacity and fossil fuel supply. According to a recent report of the Stanford Research Institute—'', space heating and cooling for residential and commercial buildings amounts to approximately 2 07o of the total energy consumed in the United States, which

was 60 trillion Btu per year in 1968. Moreover, recent and frequent blackouts and brownouts in the east coast region of the United States are good

indications that the electric power demand for summer air conditioning

exceeds for certain times, the capability of supply and distribution by

the power companies.

It is in this context that new and accurate methodology for energy

calculations is most crucial for the design and analysis of the performance of space heating and cooling systems. This is especially true in

view of the fact that the current load calculation procedures could lead

to the over-design of heating and cooling equipment and imprudent use of

energy.

It is generally accepted that buildings can be designed to be energy

effective if their thermal insulation is increased; window size, air leakage, and lighting levels decreased; shading devices properly installed;

heating and cooling systems adequately designed, installed, and maintained;

and their heat storage capability most fully utilized. These energy saving features, however, must be considered with reference to numerous constraints, such as added costs for material, construction and maintenance,

1
conformance to local building codes, occupancy life styles, aesthetics,

construction practices, and availability of equipment.

In spite of these constraints, there is sufficient engineering information and technical basis that exist today to warrant extensive studies on various design alternatives for heating and cooling the building

to minimize the wasteful use of energy. Design and operation of heating

and cooling systems based upon conventional steady-state calculations,

for example, usually result in oversizing of equipment and overheating

or cooling of the space to be controlled. An over-design system usually

operates at lower efficiency and needs more material (consequently more

energy) to produce it, thus creating a vicious cycle.

One effective way to design the heating and cooling systems which

is optimum from the standpoint of energy consumption, peak power demand

and many practical constraints mentioned above, is to study the building

thermal performance by using accurate simulations. Because of the use

of computer simulations make it possible to evaluate the sensitivity of

various design alternatives on the net energy usage, they can be a very

effective tool in the design process. In order for such design studies

to be conducted on the computer however, the computer program to be used

should be very comprehensive and should indicate the proper response to

the change of the many parameters which are pertinent to energy usage.

The intent of this document is to present a more detailed calculation

methodology than is generally used to make it possible for engineers to

reduce the area of approximation, where this is considered desirable, by

a rigorous computer simulation of building systems, which consider and

take into account most of the variables that affect the building and

2
system operation.

Refined and sophisticated calculation procedures unfortunately are

both time consuming and expensive. Without the use of advanced computer

methods, they aire literally impossible. The development of such calculation procedures can only be justified on the basis that the more accurate

calculation will result in overall savings in energy usage and owning and

operating costs and consequently in total life cycle cost due to better

design of the building systems, more precise sizing of the equipment, and

more carefully controlled operation of the heating and cooling system.

There are many indications that such a justification is well warranted.

2. Fundamentals of Heating and Cooling Load Calculation

Calculation of the energy requirements of the heating and cooling

system of a building involves three major steps which may be carried out

simply to achieve approximate results, or with increasing degrees of complexity and sophistication as more accurate and more refined determination

of system performance is required. First, is the calculation of heat loss

or heat gain to the space which is heated or cooled. Second, is the determination of the heating and cooling load imposed on the system. Third,

is the calculation of the energy input to all of the system components to

satisfy that load.

2/

The ASHRAE Handbook of Fundamentals— contains the basic information

whereby the heating and cooling load of a building may be calculated. Customarily such load calculations are made for the so-called "design conditions" for sizing the equipment and developing the design of the heating

and cooling system. However, the "design conditions" normally exist only

• 3
for a very few hours, if at all, during a heating or cooling season.

Consequently, the actual day-by-day and hour-by-hour heating and cooling

load for energy consumption is quite different from that for the design

condition. Thus the heating and cooling load calculation for the purpose of estimating "energy requirements" must reflect the actual weather

conditions rather than a design condition.

Various methods have been developed in the past such as the "degree

day" method or "bin" method for proportioning the design load, to obtain

approximate monthly, daily, or hourly loads and consequently provide a

basis for determining energy requirements. Insofar as such methods are

based on valid approximation procedures and checked against actual operating experience, they provide the base for simplified determination of

energy requirements acceptable for the needs of most engineers.

In this section a review of the rigorous methods of calculating

heating and cooling loads by means of solving heat balance equations at

all the interior surfaces of a room or space is given. Also described

are approximate methods in which weighting factors are developed after

the heat balance equations have been solved for one set of conditions.

The NBSLD calculations follow the rigorous method while the ASHRAE Task

Group procedures use the weighting factor method.

In NBSLD the transient heat conduction through exterior walls of

the room or space is handled by using conduction transfer functions.

The use of heat balance equations at the interior surfaces, although

more time consuming, can avoid the vagueness and uncertainties inherent

in the weighting factor approach. In addition, it is more accurate for

a specific building design.

2.1 A Rigorous Method of Calculating Heating and Cooling Loads

A cooling (heating) load is of course the amount of energy that is

transferred to (from) the room and simultaneously removed (added) by the

conditioning equipment at any given time of interest. To calculate this

quantity directly requires a rather laborious solution of energy balance

equations involving the room air, surrounding walls, infiltrating and

ventilation air, and internal energy sources. The principle of calculation can be demonstrated by considering a fictitious space that is enclosed by 4 walls, a ceiling and floor, and having infiltration air as

well as normal internal energy sources. The six equations that govern

energy exchange at each inside surface at a given time t are:

m

q, = h^^. (t^ - t, ) + S 4 (t, - t^. ) + RS^. + RL. + RE

j

ijt a.jt i,t =

ij j,^ i,t i,t ijt ijt

for i = 1,2, 3,4, 5, 6

where

m = number of surfaces in the space

q. = rate of heat conducted into surface i at the inside

surface at time t

h , = convective heat transfer coefficient at interior

ci

surface i

g. . = radiation heat transfer factor between interior

surface i and interior surface j

t = inside air temperature at time ^

5
t. = average temperature of interior surface i at time ^ ^ 't t . = average temperature of interior surface j at time ^ J Jt RS, = rate of solar energy coming through the windows and

absorbed by surface i at time ^

RL. = rate of heat radiated from the lights and absorbed

by surface i at time ^

RE. = rate of heat radiated from equipment and occupants

and absorbed by surface i at time t

The equations governing conduction within the six slabs cannot be solved

independent of the above equations since the energy exchanges occurring

within the room affect the inside surface conditions which in turn affect

the internal conduction. Consequently, one is faced with solving six

equations simultaneously with the governing equations of conduction within six slabs in order to calculate the cooling load at time of interest

(Q ) which would be given by

where

p = air density

C = air specific heat

G- = mass flow rate of outdoor air infiltrating into the

space at time ^

t = outdoor air temperature at time ^

6
v,t = mass rate of flow of ventilation air at time ^

t = ventilation air temperature at time ^

RS = rate of solar heat coming through the windows and

convected into the room air at time ^ RL = rate of heat from the lights convected into the room

air at time ^

RE = rate of heat from equipment and occupants and cona»t

vected into the room air at time ^ A rigorous approach such as this for calculating cooling load would be

practically "impossible if it were not for the speed at which such computations can be done by modern digital computers. Even so, there are very

few computer programs in use today where instantaneous cooling loads are

calculated in this exact manner. The concept, however, has been presented

3/ 4/ previously by Stephenson and Mitalas— , and by Buchberg— .

Not to be ignored is the effect of air temperature deviation from

some prescribed set point. This set point is the temperature for which

the cooling (heating) load calculation is made and for which the design

capacity of the cooling (heating) apparatus is usually selected. A recent study by Mitalas and Stephenson—'^ shows that actual heat extracted

from the space is considerably smaller than the cooling load calculated

on the basis of a constant space temperature. This is due to the thermal

storage effect of the building structure and internal furnishings. Figure 1 shows a result from that study and as can be seen, the calculated

cooling load peaks at values considerably higher than the measured heat

extraction rate.

2.2 Approximate Methods of Calculating Heating and Cooling Loads

Since the exact solution technique is extremely time consuming especially for the calculations done for a period of 8760 hours (one year),

the ASHRAE Task Group on Energy Requirements recommends a transfer function concept to simplify the calculation procedure. The transfer func3/ tion concept was first introduced by Mitalas and Stephenson— using what

they called room thermal response factors. Their procedure is as follows:

the room surface temperatures and cooling or heating load are first calculated by a rigorous method as described in the previous section for several typical constructions representing offices, schools and dwellings of

heavy, medium and lightweight construction. In these calculations, the

components such as solar heat gain, conduction heat gain, or the heat gain

from the lighting, equipment, and occupants are simulated by pulses of

unit strength. The transfer functions are then calculated as numerical

constants which represent the cooling load (or heating) corresponding to

the input excitation pulses. Once these transfer functions are determined

for a number of typical constructions, they are assumed to be independent

of input pulses and the determination of cooling loads (or heating) is

possible without resorting to the rigorous calculations. The calculation

required is, instead, simple multiplication of the transfer functions by

a time-series representation of heat gain and the subsequent summation of

these products, which can be carried out on a small computer with little

effort

.
Another way to shorten the computational effort for energy calculations is to determine regression parameters by fitting a simple algebraic

equation to the results of rigorous calculations, which had been obtained

not for an entire year but for a limited period in the year, such as for

the months of January and/or July. Once this regression equation is determined with sufficient accuracy, an energy estimate is made by superimposing the weather conditions of the other months onto the relationships

just determined.

An example of this approach is illustrated in Figure 2, which depicts

the daily total heating and cooling load plotted against the daily average outdoor air temperature. This plot is a result of a lengthy rigorous

calculation performed on a typical apartment in Jersey City using the annual hourly weather conditions that occurred in 1949. The straight lines

superimposed on the figures were the least square regression lines that

best fit the calculated loads for January and July. It was clear from

this figure that the exact calculations for other months would not be necessary, at least for the purpose of determining daily loads, since the

regression relationship determined from the January and July calculations

were sufficiently accurate that they could be extrapolated to the remainder of the year.

Depending upon the type of building and its heating and cooling system, a good correlation such as illustrated in Figure 2 may not be possible. Figure 3 shows, for example, a similar plot for a test office building whose heating and cooling load were measured in a research project

conducted by Ohio State University. The scatter appears considerably

larger than the calculated relationship obtained in the Jersey City study.

12
It is obvious that the thermal performance of commercial buildings are

affected in a large way by the manner in which internal heat is generated

in addition to the normal dependence on outdoor temperature. The inclusion of one or more additional statistical parameters dealing with these

internal heat gains should improve the correlation.

Recently one additional method of predicting the heating and/or cooling load or the indoor temperature as a result of the excitation parameters such as outdoor temperature, solar radiation and internal heat generation has been demonstrated by Kusuda and Tsuchiya~^ and further expanded

by Kimura and Ishino—^. The method uses the concept of equivalent thermal mass of a building and attempts to fit the observed input and output

data into a linear differential equation. The initial results are promising. Figure 4 shows a comparison of predicted and measured room temperature and heat extraction rate for a simple one room test building

studied by Kimura and Ishino,

Calculated room temperature in Figure 4 is obtained by the transfer

functions derived from the measured data of August 19, while the heat extraction was calculated by the transfer functions derived from the measured values of August 13. The good agreement indicated in Figure 4 implies that the detailed calculation is needed only for a limited number

of days to derive accurate transfer functions based upon the equivalent

thermal mass of the particular building under consideration.

3. Unique Features of NBS Load Calculation Computer Program

A comprehensive yet easy-to-use computer program for determining

heating and cooling loads has been developed in the Thermal Engineering

Section of the Center for Building Technology at the National Bureau of

Standards. This computer program is based upon extensive information ac

cumulated over the past decades in various phases of building heat trans

fer problems, and is intended to be used for the design of equipment and

air conditioning systems as well as for estimates of building energy requirements.

The major reason why NBS developed this comprehensive program is

that despite the existence of numerous load calculation programs current

ly available, most of them are not suitable for the analysis of building

designs where non- conventional or innovative ideas on structures, heating and cooling systems and controls are employed. Some of the unique

aspects of building and system design and operation that can be handled

by or studied by using NBSLD are:

1. Inside-out construction of exterior walls where the thermal insulation is placed on the outside of the building

shell as opposed to conventional walls having insulation

on the inside. (These two walls could have the same Uvalue and yet their thermal response would be quite different.)

2. Effect of interior partition walls or floor-ceiling sandwich structures on the heat storage characteristics of

the room,

15
3. Off-peak heating or cooling of buildings to shave the peak

heating or cooling demand,

4. Evaluation of intentionally undersized heating and cooling

equipment by calculating the room temperature and humidity

deviations from a design set point. (The results would indicate whether or not the indoor conditions would remain

within acceptable limits.)

5. Evaluation of indoor thermal environment of various zones

during the intermediate season, such as spring and autumn,

when the heating or cooling requirements for these zones

may not be in phase with that of the building as a whole.

(This would apply to a case where a two-pipe system would

be installed for example. The central system for the entire building might be switched to heating in late autumn

and yet some zones, particularly those facing south may

still require cooling. NBSLD can be used to determine the

indoor thermal conditions of unheated or uncooled rooms.)

6. Use of solar energy for heating and cooling buildings as

it relates to the thermal storage characteristics of the

building

,

7. Use of attic ventilation to reduce the cooling load since

NBSLD can accurately predict attic temperatures,

8. Accurate determination of the need for heating and air conditioning in basement rooms ,

16
9. Design of heating and cooling systems and equipment on the

basis of intermittent operation , such as the shutdown of

air conditioning facilities during the nighttime or weekends ,

10. Effective use of natural air conditioning such as ventilation, shading, increased ceiling insulation and the subsequent determination of the requirements for mechanical

cooling,

11. Effective use of planned ventilation 111 1 to minimize a building heating load during the winter season,

12. Accurate evaluation of indoor comfort conditions based

upon air temperature, humidity and mean-radiant temperature,

13. Determination of the condition whereby moisture condensation takes place along interior surfaces of a building.

Figure 5 depicts an overall calculation sequence to attain the hour

by hour heating and cooling load of buildings. Shown in the double lined

boxes are input data to be supplied whereas those in single lined boxes

indicate calculations to be performed. The cycle indicators show the

iteration cycles for the number of buildings, the niimber of rooms in a

given building and the number of days for which the calculations are performed. More specific identification of the types of input data needed

are listed in Figures 6, 7 and 8. The exact way the input data is put

into the program is specified in Appendix C.

4, General Description of NBSLD Subroutines

In order to perform the chain of calculations depicted in Figure 5

a number of subroutines were developed at the National Bureau of Standards, the algorithms of which have already been published through the

ASHRAE Task Group booklet entitled "Procedure for Determining Heating

and Cooling Loads for the Computerized Energy Calculations". This book

let, however, contained several errors which have been corrected and is

attached to this report as Appendix A. NBSLD incorporates most of the

revised ASHRAE algorithms as they are written; however, some of them

have been combined or split to fit the overall computational scheme in

NBSLD. Listed below is a brief description of the NBSLD subroutines

with their specific reference to the ASHRAE algorithms in parentheses.

1. ABCD, ABCDP, ABCD2 , ABCDP2 , DERVT, GPF, MULT, RESF,

RESFX, RESPTK: These routines are parts of the conduction transfer functions calculation package and

are needed for the accurate evaluation of thermal

time lag, damping, heat storage in exterior facing

surfaces as well as the internal furnishings. (XYZ)

2o AIRCON: This routine is used to determine instantaneous values of the physiological indices for the

space being studied such as ASHRAE 's New Effective

Temperature, Predicted Mean Vote (Fanger), Heat

Stress Index, KSU Index, Resultant Temperature, Operative Temperature, and Index of Thermal Stress

(Givoni), - not included in the text

22
ATTIC: Attic space temperature and heat conduction through

the ceiling into the room below are calculated by this routine for the vented or non-vented attics. (ATTIC)

CCM: This routine modifies the solar radiation computed

for a cloudless sky by instantaneous cloud cover data.

(CCF)

DPF: This routine calculates dew point temperature of atmospheric air when the partial vapor pressure is known.

(PSY)

DST: This routine determines whether a given data is in

a daylight saving time zone. The information is needed

for the proper assignment of the energy usage schedule.

(DST)

FCTR: This routine determines radiation exchange factors

between any two surfaces which are part of a given room.

For the room of six interior surfaces, for example, thirty

radiation exchange factors are calculated. These factors

are used in turn to determine the rate of heat exchange by

radiation between all the interior surfaces. (FIJ)

F: This routine calculates radiation heat exchange factors (form factors) between two adjacent rectangular surfaces which are normal to each other, such as that between

the floor and wall. (FIJ)

23
9. FO: This routine calculates the surface heat transfer coefficients for externally exposed surfaces from weather

data. (FO)

10. GLASS: This routine calculates solar heat gain through

glass when the shading coefficient, orientation, and type

of glass are given. (SHG)

11. HOLDAY: This routine identifies the national holidays in

the United States so that the proper holiday schedule can

be used for the energy calculation. (HOLIDAY)

12. OUTSID: This routine calculates the outside surface temperature and heat gain into the wall or roof by taking into

account solar heating, back radiation to the sky, convective heat loss to the ambient air and transient heat conduction within the wall or roof. (HEATW)

13. PSYl: This is a psychrometric rout ine that determines the

thermodynamic properties of moist air when the dry-bulb

temperature, wet-bulb temperature and barometric pressures

are given. (PSY)

14. PSY2: This routine is similar to PSYl except that the dew

point temperature is required instead of the wet-bulb temperature. (PSY)

15. PVSF: This routine determines the saturated vapor pressure of atmospheric air as a function of temperature.

(PSY)

16. RMTMP : This is the single most important subroutine of

NBSLD since it determines the room temperature by solving

matrix equations expressing a balance of heat gains, heat

storage at the room surfaces, and cooling capacity of an

air conditioning unit. However, the room temperature can

be prescribed, in which case the routine will calculate

the heating /coo ling requirements to satisfy that prescribed

temperature. (RMTMP)

17. ROOM: This routine reads in all the data required for the

room heat transfer calculation such as dimensions, surface

orientations, shading coefficients, surface solar absorptivity, etc.

18. SHG: This is the routine that calculates solar heat gain

through glass. (SHG)

19. SOLVP : This routine solves the simultaneous linear algebraic equations that appear in RMTMP. (RMTMP)

20. SUN: Basic sun data such as solar angles, cloud cover,

direct and diffuse radiation needed for solar heat gain

and solar heating of the building exterior surfaces are

calculated in this routine. (SUN, SOLAD)

21. TAR: This routine calculates transmission and absorption

characteristics of glass. (TAR)

22. WBF: This is another psychrometric routine that calculates the wet-bulb temperature when the enthalpy of moist

air and the barometric pressure are specified. (PSY)

25
23. WKDAY: This subroutine determines the day of week when

the date and year are given. The information is needed

for the proper selection of energy usage schedules which

are dependent upon whether the day is a weekday or not

.

(WKDAY)

24. WD, WDX, DECODE, ERROR, WEATHE : The weather data tape

1440 supplied by the National Climatic Center, Asheville,

N. C. is prepared in a format which cannot be readily applicable in most of the Fortran programs. These routines

are therefore necessary to read the 1440 tapes and decode

them into meaningful weather parameters, which in turn

can be used by UNIVAC 1108 Fortran of the National Bureau

of Standards. If there are some data which are unreasonable, the data will be replaced by the arithmetic average

of two adjacent data by the ERROR routine. (CLIMAT)

All the subroutines in the program may be used to form a separate

main program for a specific job. Following are sample usages of some

of the subroutines.

26
1. Psvchrometrlc Calculation

CALL PSYl (DB, WB, PB, DP, PV, W, H, V, RH)

where Inputs are DB = dry-bulb temperature

WB = wet-bulb temperature

PB = barometric pressure

outputs are DP = dew point temperature

PV = vapor pressure

W = humidity ratio

H = enthalpy

V = volume

RH = relative humidity

There is also a routine c^.lled PSY2 (DB, DP, PB, WB, PV,

W, H, V, RH) in which the inputs are DB, DP and PB instead of DB, WB and PB. In many cases DB and RH are the

inputs and the vapor pressure and dew point temperature

or the wet-bulb temperature at standard barometric pressure are the outputs. A possible algorithm that could be

desired, for example, might be:

PVS = PVSF (DB)

PV = PVS* RH/ 100

DP = DPF (PV)

Call PSY2 (DB, DP, PB, WB, PV, W, H, V, RH)

27
2 . Solar Radiation

Recently there has been increased interest in the application of solar energy for heating of hot water. SUN and

GLASS routines should be valuable for evaluating various

solar collectors at different locations in the United

States at different times of the year. A sample use of

these routines may be shown for a solar collector having

the following characteristics (Figure 9)

location: latitude =45°, longitude =73°

azimuth angle = 0° south

tilt angle = 30° from horizontal surface

2

. area = 500 ft

date = July 21

time = 4 : 00 p.m.

glass cover = double sheet - clear glass

U = overall heat transfer coefficient between the colR

2 lector surface and the ambient, Btu/hr ft "F*

U„ = overall heat transfer coefficient between the colW

lector surface and water, which is being circulated

2

under the collector plate, Btu/hr ft °F

TWI = water temperature entering the collector, °F

TWL = water temperature leaving the collector, °F

GPM = water circulation rate in gallons per minute

When the collector temperature is less than 150 °F, the typical value

of Uj^ for a flat black collector with double glass cover may be 0.75.

The value increases to as much as 1.5 when the collector temperature

is in the neighborhood of 300 °F. A special computer program is available for estimating the value of Uj^ for various types of collectors.

28
29
It is assumed that the collector is well insulated around

the edges and its bottom.

The algorithm for the use of SUN and GLASS routines would

then be

S(l) = LATITUDE =30

S(2) = LONGITUDE = 73

S(3) Time zone number = 5

S(4) Elapsed days since January 1 = 202

S(5) Time = 16

S(6) IDST = daylight saving time index = 1

S(7) Ground reflectivity = 0.2

S(8) Clearness number =1.0

S(33) = Cloud cover modifier = 1

S(9) = Azimuth angle of the collector = 0°

S(10) = Tilt angle of the collector = 30°

Call SUN

Call GLASS (SHDW, SHADE, GLASTP, GLAZE, SHG)

note : SHDW = sunlit area factor = 1

SHADE = shading coefficient = not applicable

GLASTP = 1/8" double strength glass (1)

GLAZE = double glazing (2)

SHG = solar heat gain - output

30
note: SUN and GLASS have S in common using the solar

heat gain through the glass plate. When the

edge heat loss is small, the following calculation may be used to estimate TS, collector surface and TWL, leaving water temperature from the

collector:

^ A*(SHG + UR^DB) + SOOvGPI^^TWlVcY

UR^vA + 50OvGPM>VY

where Y = 1 - e ^

where X = 50OGPM

A Procedure for Obtaining Climatic Weather Data

Climatic parameters needed for the hourly load calculations are:

DB: Dry-bulb temperature, F

DP or WB: Dew point or wet-bulb temperature, F'

CT: Cloud type

TP • lULctJ. C-Loua dmounc

V . Wind speed, knots

DIR: Wind direction (clockwise from North), degrees

PB: Barometric Pressure, in. Hg

ID: Direct Solar Radiation, Btu per (hr) (sq ft)

''"djSky

* Sky diffuse radiation, Btu per (hr) (sq ft)

'''d , ground

'

Ground diffuse radiation, Btu per (hr) (sq ft)

Rain, Snowfall: Precipitation data (Optional)

Hourly observations of these weather parameters for past years are

available from the National Climatic Center either on magnetic tape or

in card deck form. The hourly solar radiation data has been recorded

for only approximately fifty stations throughout the United States (Table A-1). These data are, moreover, limited in their durations and completeness, and scarcely useful for the comprehensive energy analysis.

On the other hand, the data series 144 includes the hourly observations

of all of the parameters listed above except the solar radiation for more

than 300 weather stations (Table A-2 ) covering a period of from ten to

thirty years. Since the 144 series data are very much complete, it is

la
recommended that hour by hour energy calculations be made with this series

of data supplemented by simulated solar radiation data. A method for simulating solar radiation will be described later in this booklet.

Because of the specific coding scheme employed by the National Climatic Center for storing the hourly weather data onto the magnetic tapes,

the 144 series is not directly usable by the standard Fortran programs.

Different computing systems such as IBM 370, CDC 6600 and UNIVAC 1108

have their own decoding routines to read these tapes. Included in this

section is a listing of a Fortran program which illustrates a decoding

scheme required to make use of the weather tapes. This listing was prepared by Mr. McKay, Data Reduction Section, of the National Climatic Center, Asheville, North Carolina.

CCF

An Algorithm for the Calculation of Cloudy Day Solar Radiation

This routine estimates the factor called CCF to modify the total

solar radiation on a horizontal surface with the observed cloud cover

data for a cloudy sky condition. The cloud cover observations are made

every hour at major weather stations by experienced observers who estimate the amount of cloud on a scale of 0 to 10 and indicate the type of

cloud in four different layers. Kimura and Stephenson—'' analyzed 1967

Canadian data for observed solar radiation with respect to the cloud

cover data, type of cloud, and the calculated solar radiation under a

cloudless condition at the same solar time. Based upon their analysis,

a comprehensive methodology was developed for calculating the cloudy

day solar radiation. The value of CCF, Cloud Cover Factor, is first

defined as follows:

CCF = ITHC/ITH

where

ITHC: Total solar radiation on a horizontal surface

under a cloudy sky of given cloud amount and

types of cloud

ITH: Total solar radiation calculated for a horizontal surface under a cloudless sky at the

same solar hour as of ITHC

15a
Data ;

IS : Season index

CAj : Cloud amount at the j-th layer, where j = 1, 2, 3, and 4

TOCj : Type of cloud at the j-th layer, where j = 1, 2, 3, and 4

TCA: Total cloud amount

Calculation Sequence:

1. X = (rCA,)^.^^^^ + (^'^j'clrrostratus ^ ^clrrocumulus

2 . Cloud cover

CC = TCA - 0.5*X

3. Cloud cover factor

CCF = P + Q>VCC + R-A'CC>v*2

where P, Q, and R are found in the following table

Table A-6

Season P Q R

spring 1.06 0.012 -0.0084

summer 0.96 0.033 -0.0106

autumn 0.95 0.030 -0.0108

winter 1.14 0.003 -0.0082

The value of P, which is essentially the cloudless sky factor, depends upon the proportion of direct to diffuse sky radiation in reference

to the standard ASHRAE values published in the 1972 Handbook of Fundamentals. If the value of P is unity, this proportion of direct to diffuse

solar radiation is such that the solar radiation evaluated for a hori16a
1

zontal surface under a cloudless sky should be equal to the value obtained

by the method described in the 1972 ASHE^E Handbook of Fundamentals. If

the value of P is different from unity, the direct to diffuse proportion

is different from the standard values.

SOLAD

An Algorithm for Determining Diffuse and

Direct Radiation Falling Onto a Surface

This routine determines the total as well as the diffuse and direct

the previous section.

CCF routine

WA: Azimuth angle of the surface under consideration

SHADOW

A Brief Description of the Procedures for Calculating External

Shadows on a Building

A major portion of the air conditioning load on modern commercial

buildings comes from solar radiation. To improve the accuracy of load

assessment, it is necessary to know how much of a building is shaded and

how much lies exposed to the sun's rays.

4/ A new technique developed by Groth and Lokmanhekim— employs the

representation of all architectural forms as a series of plane polygons.

Even curved surfaces can be so represented. For example, a sphere may

be approximated by the 2 0 sides of a regular icosohedron. This approximation gives a maximum error of only 3% in the shadow area cast by the

sphere.

The output of the algorithm is not only the sunlit area, but also

a pictorial display of the shadows and the surface upon which they are

cast

.

Coordinate Transformation:

Designate the polygons which cast shadows as shading polygons (SP)

and those upon which shadows are cast as receiving polygons (RP). The

vertex coordinates of each RP, and its relevant SP ' s , are transformed

from a base coordinate system, xyz , to a new coordinate system, x'y'z',

with origin 0 attached to the plane of the RP. The first three vertices,

31a
V^, V^t and V^, of the RP being examined are used to define this new coordinate system. The x' axis passes through V2 and V^, while the y' axis

passes through V^. In order that the z' axis point outward from the surface, angle ^]i^2^3 convex and the vertices must be numbered counterclockwise. The equation of transformation is written in matrix form

as

x' = A (x-Xq)

where

—i —> —* —

Xq = X2 + y(.x^-x.2)

Y, A Scaler = (x-^-k^) • (K^-x^^/ix^-x^) ° (x^'x^)

1st row of A = (x^-Xq)/ I x-j'Xq \

2nd row of A = (Xj^-Xq)/ | Xj^-Xq |

• -» -» _» 3rd row of A = 1st row of A x 2nd row of A

Solar altitude, o-, and azimuth, p, must also be transformed, into

the solar direction vector, as

, /Sing • CosQ?

X Sincy

J Cosg • Cosa

Clipping Transformation:

Any part of an SP whose z' is negative cannot cast a shadow on the

RP. These "submerged" portions of the SP's must be clipped off, prior

to projection, lest they project "false" shadows (see Figure A-6). This

32 a
is done by finding, through linear interpolation, the points A and B,

on the perimeter of the SP, which pierce the plane of the RP, and taking

these points as new vertices. All submerged vertices are deleted. This

results in a new polygon with line AB as a side, which will project only

real shadows.

Figure A-6 Clipping

Projection Transformation:

To simulate the actual casting of a shadow, the following transformation projects, along the sun's rays, all the vertex points of the transformed and clipped RP's.

x'

33a
Enclosure Test:

The coordinate, clipping and projection transformation have converted

all RP and SP ' s in space into two dimensional figures in the RP plane.

It remains only to find the points in the RP plane which lie inside the

RP and inside one or more of the SP projections, i.e., points of the RP

which are shaded. At this point, the two-space XY is divided into a grid

and the center of each element of this grid is tested for enclosure by

the RP and the SP projections. A point, P, whose coordinates are XpY^,

is inside of polygon ' " following inequality holds.

nS AG. ?^ 0

The angular change, A9^, subtended at P by the ith side, and counted

positive counterclockwise, is given by the following formulae.

These approximate formulae, which express A0^ in right angles, replace the time-consuming square root and are cosine computer library routines. They have, by set theory, been proved adequate for the purpose.

Display Matrix and Sample Problem:

An alphameric matrix is created corresponding to the grid elements

in the RP plane. A blank component represents a grid element either outside the RP or exposed to the sun. An asterisk component represents a

shaded grid element or one on the RP's boundary. Grid elements shaded

by a transmissive structure are randomly asterisked with a probability

equal to the fraction of incident light stopped by the shading structure.

Figure A-7 shows the solution of a typical problem involving a transmissive structure.

An Algorithm to Determine Whether or Not a Given Window is

Shaded by a Remote Object Such as an Adjacent Building

This algorithm is approximate and is applicable only where the window is relatively small in comparison to the shading object. Large windows may be subdivided into smaller segments for this consideration. Th

window is considered either completely shaded or completely in sun. Par

tially shaded window can be considered in either case depending on the

location of the window reference point. Figure A-9 shows a typical window-shading object relationship.

PLAN ELEVATION

Figure A-9 A Typical Window-Shading Object Relationship

Note that the reference point can be located at any point on the window.

Locating the reference point at the top of the window as shown in the

elevation in Figure A-9 is slightly conservative as compared to if the

reference point is located at the center of the window.

Data ;

al, aZ' Azimuth shadow limit angles. Right +, Left -

pl, p2 : Altitude shadow limit angles

WAZI: Window azimuth angle

PHI: Solar azimuth angle

BETA: Solar altitude angle

Calculation Sequence ;

This subroutine determines whether the window is sunlit or shaded

fpr the given position of the sun.

1. Wall-solar azimuth angle

GAMMA = PHI - WAZI

2. If GAMMA < c^l or GAMMA > ^2, the window is in sun

3. If q2 > GAMMA > al,

A = GAMMA - al

B = pi + Ay^(32 - pi)

4. If BETA > B, the window is in sun. Otherwise, the window

is in shade.

A Description of the Calculation Procedure for Transient

Heat Conduction Using Conduction Transfer Functions

Conduction transfer functions are used widely and considered as a

convenient and effective tool for the evaluation of transient heat transfer in building construction components. The conventional steady state

heat transfer equation for calculating heat loss:

Q = U (T - T ) (I) a o ^ '

where

U: overall heat transfer coefficient of roof or wall

T^: inside air temperature

T^: outside air temperature

is not sufficient for evaluating transient heat transfer. This equation

becomes invalid because the outdoor temperature T^ usually varies as affected by solar radiation, cloud cover and wind effect. The effect of

the rapid change of the outdoor temperature will not be accounted for unless the structure is extremely lightweight, such as galvanized steel.

Approximate calculation for a more accurate determination of the instantaneous heat transfer can be made by replacing T^ - T^ of equation

(1) by a Total Equivalent Temperature Difference (TETD) which is usually

precalculated for typical building construction components and takes into

account the thermal storage effect. Although very useful, the TETD concept is only valid when the outside temperature T^ undergoes steady periodic changes. The TETD concept is therefore especially useful computing

design heat transfer rates for the building where very warm or very cold

71a
conditions are assumed to occur for several successive days.

A more accurate formulation for conduction heat transfer from a room

to randomly fluctuating outdoor conditions is to use the hourly history

of temperatures in conjunction with Conduction Transfer Functions (CTF).

For example, in calculating the energy transfer from a room at an inside

surface, the equation would be:

N N

Q. ^. ^'t

= S X.'VT ^ . - 2 Y.'VT + R.vQ , (2) .^Q J a,t-j .^^ j o,t-j ^ ^t-1

where , (for j = 0, 1, 2 ... N), and R are the Conduction Transfer

Functions. In equation (2 )

, T . and T . represent outdoor and room a,t-j

air temperatures respectively at jth hour prior to the time for which the

value of Q is needed. And Q , is the heat loss Q , from the room at

t t-1 t the previous hour. By having a record ofT ^i,T o>T „... ° o,t-l o,t-2o,t-3

T ^ . ; and T ^ t , T „ • • • T . ; it is possible to determine the o,t-j a, t-1 a,t-2 a,t-j

instantaneous conduction transfer, provided that the values for X. and

J Y., and R are available.

J The number of terms involved for the calculation of (or the value

of N in equation (2)) depends upon the type of roof or wall construction.

Generally heavy constructions require a large value, although for most

8 / conventional constructions, it seldom exceeds 2 0. Stephenson amd Mitalas~

have shown that the value of N can be further decreased by employing more

than one past record of (or ^ with j being more than 1) in the following manner

72a
N' N' N

,t 2 a,t-j J o,t-j J ^i,t-j

where A., B., and D. are the Modified Conduction Transfer Functions acJ J J 8/ cording to Stephenson and Mitalas~ . Table A-10 gives values of Conduction Transfer Functions calculated for a brick wall having an overall heat

transfer coefficient of 0.418. In this table, the factors designated by

Z, and C. are the additional transfer function to be used for evaluating

J J the instantaneous heat loss Q ^ at the exterior side of the structure.

o,t

The applicable equations for this side of the structure are then:

N N

Q = 2 Y.VrT ^ . - S Z.V.T ^ . + R?VQ (4) o»t J a,t-j J o,t-j ^o,t-l

or

N' N' N'

Q = 2 B ,vT - E C,.vT^.'VT . - S D,*Q„ (5) - S D.*Q

The table also shows that for the calculation of Q the use of Stepheno ,t son type transfer functions would permit the reduction of N from 10 to

N' = 4 with a corresponding increase of three terms in the past record

of Qo,t

:

NL: Number of layers to be considered for the analysis

of a given structure: the number of layers should

include surface resistance or air cavity resistance

if they contribute significantly to the overall heat

transfer of that particular structure

K^: Thermal conductivity of i-th layer in Btu per (hr)

(ft) (F). This value is not needed for air cavities or for the surface resistance layers.

p^: Density of i-th layer in lb per (cu. ft). This

value is not needed for air cavities or for the

surface resistance layers.

C^: Specific heat of i-th layer material in Btu per

(lb) (F). This value is not needed for air cavities or for the surface resistance layers.

L, : Thickness of the i-th layer in ft. This value

X is not needed for the air cavities or for the

surface resistance layers.

RES. : Thermal resistance of air cavities and surface

1

resistance layers in (hr) (sq ft) (F) per Btu.

This value is not needed whenever all of the

remaining values such as K^, p^, and are

given.

75a
DT: Time increment for the conduction transfer functions

in hr (usually one hour for the building heat transfer calculations)

Subscript i refers to i-th layer and it varies from 1

to NL.

The sequence of input ing the above property values for each layer

is very important and must be consistent with the particular convention

adopted for the specific calculation routine. The sequence must follow

in order from the inside layer to the outside layer or vice versa. It

should be noted that the inclusion of the surface thermal resistance as

independent layers is optional depending upon the end use of the conduction transfer functions. If the inside surface temperature is to be computed as a balance of all the heat flow involved at that surface, the

thermal resistance of the inside surface should not be included in the

calculation of the conduction transfer functions. The same comment applies for the outside surface.

An algorithm for the calculation of the conduction heat transfer

functions will not be given here, since it involves lengthy mathematical

solutions to the standard transient heat conduction differential equation. Reference (9) provides an excellent background for this calculation. Several computer programs"^^"^"*

~^ are available for the calculation

of conduction transfer functions for multi- layer walls, roofs and floor

constructions. The program developed by the National Research Council

of Canada—'^ requires the layer input to be placed in order from outside

toward inside. It calculates the Stephenson type conduction transfer

76a
functions directly. The program of the National Bureau of Standards—^

requires the input to be placed from the inside layer first and calculates the conduction- transfer functions of plane, cylindrical and spherical walls. It also calculates the transfer functions for solid objects

of plane, cylindrical and spherical shapes as well as the heat conduction

systems involving semi-infinite solids, approximated by basement floors

and underground constructions.

Under non-steady heat conduction, the heat lost from one side of a

surface is not equal to the rate of heat entry at another side. Equations

(2) and (3), however, must be valid also for the steady state heat transfer problems. One of the best ways to check the consistency of the conduction transfer functions is to use them in the solution of steady state

problems and see if the following criteria is met : The room side surface

temperature and the outdoor side surface temperature are maintained constant for many hours so that

TOS^ = TOS^ , = TOS^

t t - 1 t -N

TIS^ = TIS^.l = TIS^.N

QI^ = QO^ = QO^.l = QI^.i

Throughout this discussion a value of TM is always subtracted from

the interior surface and exterior surface temperatures. This sub=

traction usually helps to minimize the digital errors which occur

and are sometimes significant when a large number of numerical data

are multiplied and added. Since N N , the net effect of

the subtraction is zero. S X. = S Y.

j=0 J j=0 J

This expression was developed to yield a roof sky radiation of 20 Btu

per (hr) (sq ft) for a cloudless condition, which was reported in Ref- erence (12).

Figure A-17 shows the energy balance that is involved in the

above calculation sequence and the results of a typical calculation. Table A-11 gives the conduction transfer functions

for the roof used in the calculations.

B. Interior walls and floor /ceiling sandwich

The calculation sequence for the partition wall and floor/ceiling

sandwich is completely different from that of the exterior wall or

roof. The difference is due to the fact that the air temperature at

the exterior side of the construction can be assiamed the same as at

the interior side, at least for a climate controlled building. In

order to take advantage of this fact, conduction transfer functions

should be determined with the surface thermal resistance layer added

at the exterior side of the structure. The heat loss through a partition wall is then calculated by

N N

HEAT = S X *(TI - TM) - S Y *(TA^ . - TM) + R*HEAT , j=0 ^ j=0 J ^'^

where TAj._^ = room temperature at time (t-j)th hour

If the room temperature were maintained constant at TM, which is usually the case, the terms involving the 's would then drop out of

the equation.

C. Slab on grade floor

The heat loss to the ground through the floor on grade can be

calculated by using conduction transfer functions determined on the

basis of flooring, concrete, and 12 inches of ground layer

84a

Since usually TG is constant and

N

E Y = U *(1 - R),

j=0 J ^

then

t-1

The same method is applicable to a floor with a crawl space as long

as the space is not vented. The conduction transfer functions for

the floor with an unvented crawl space simply has an additional air

resistance layer to account for the dead air space between the floor

and the ground. In many cases it is safe to assume that TG = TM,

and then the term involving U would drop out of the equation.

G

Floor over the vented crawl space

The floor over a vented crawl space can be treated in the same

manner as an exterior wall or roof except that the solar radiation

and sky radiation terms would not be included in the energy balance

and that the outside surface heat transfer coefficient is replaced

by a value similar in magnitude to the inside surface heat transfer

coefficient. If the conduction transfer functions include the outside surface heat transfer resistance, the calculation is simply

Fundamentals of Room Temperature and Cooling

(Heating) Load Calculations

The basic energy transfer process that occurs in a room can best be

illustrated by an electrical circuit network as shown in Figure A- 18.

The figure represents the phenomenon in a typical room having two exterior walls, each of which contains a window, and two interior partition

walls, in addition to the roof and floor (see Figure A- 19). Heat conduction paths through the walls, roof, and floor are depicted by resistance

and capacitance circuits and these through windows are represented by resistance circuits, implying that the windows do not have significant ther

mal mass. Points T_, through T„o in Figure A- 18 indicate interior surbi bo

faces of the walls, roof, floor and windows, all of which receive conduction heat through solid material, solar radiation (represented by

q) through transparent surface and long wavelength radiation from

other solid surfaces indicated by solid lines connecting the surface

nodes; and they lose heat to the room air (represented by a point called

TA) by the convection process (dashed lines).

At the top of Figure A- 18, the radiation heat exchange between the

room surfaces, the surfaces of lighting fixtures, equipment such as busi

ness machines, and occupants is depicted. Also indicated in this same

location is the convective heat exchange between these items and the

room air. Actual heat or power input to these internal heat sources are

ble to represent the conduction heat gain from the inner core of light

ing fixtures and equipment if they have sufficient thermal mass. This

equipment could of course include the unit heaters or air conditioners

indicated by Although not indicated in this figure, it is possi89a

if they are the part of the room heat exchange system. The room air

changes energy with outdoor air or with the conditioned air from the

central climate control system (or the forced ventilation system) and

is depicted in this figure by lines T T and T T . The heat exchange

s a o a

at the exterior surfaces with outdoor air, sky and sun (except for the

partition walls and floor on grade) are also indicated using a normal

design calculation procedure, the temperature or heat flow at the exterior sides of the room surfaces are usually available either by calculation or as input data. The exception occurs when two or more rooms

adjacent one another are treated simultaneously. This latter case is

commonly referred to as a "multi-room problem" and is very complex.

No satisfactory solution for this case is presently available.

This electrical network problem can be solved and the corresponding calculation algorithm is called RMTMP (given in the following section). The solution can be obtained in two different modes: room temperature calculation mode or the room load calculation mode. The room

temperature calculation mode requires the simultaneous solution of heat

balance equations in order to determine all the surface temperatures together with the air temperature. On the other hand, the room cooling

load calculation mode requires that the room temperature be prescribed

and only the room surface temperatures are solved for. The convective

heat exchange between the room air and the heat emitting surfaces is

then the cooling load (or the heating load if the heat is lost to the

surfaces). These two modes of computation can be combined to simulate

the actual thermal behavior of a room and its environment where the

temperature fluctuates. The floating temperature would be calculated

92a
as long as it remained between prescribed limits. A heating load would

be computed when the room temperature fell to the lower limit and a cooling load would be calculated when the temperature rose to the upper limit.

In this manner, the calculation of load and subsequent energy requirement

would more closely correspond to actual building and system operation.

RMTMP

An Algorithm to Calculate Thermal Load or Room Temperature

This routine calculates heating and cooling loads or room temperature by solving heat balance equations involving each of the room surfaces. A room surface receives conduction heat flow through the solid

wall, roof or floor material from behind, convection heat flow from the

air and radiation heat flow from other surfaces and internal heat sources

such as occupants, equipment and lighting fixtures.

+ QEQUP * RE + QOCPS * RO + QLITE * RL

In this expression, QL is a cooling load if positive and

it is a heating load if negative. This is the heat picked

up by the room air (or that lost by the room air) which

has to be removed (or added) by the central air conditioning system.

Note that for ordinary load calculations, GS^ and TS^ are

not used as long as the following condition is satisfied:

j QLS^ I g I GS^ * * ~ "^^t^ \ Maximum capacity

of the heating or cooling system

In other words, the desired or prescribed room temperature

can be maintained as long as the calculated load is less

than the maximum capacity of the central system. When the

above condition is not satisfied because of the inadequate

values for either the air supply rate or the supply air

temperature, the room temperature used for the load calculation is no longer valid. The calculation must then be

revised, first calculating the room temperature as outlined

in 3 above.

100a
Latent Load

If moisture condensation and absorption by room walls,

or drying of the wall panels can be neglected, the latent load is the same as the latent heat gain or loss,

provided the following condition is met:

QLLj. ^GS^ * \ * (WA - WS), where \ = latent heat

of vaporization 1061 Btu per lb of water

In other words, the desired moisture level can be maintained as long as the latent load of the room or the

building is less than the capacity of the central system to remove (add) water vapor. When the above condition is not satisfied because of the inadequate air

flow rate of the air supply system or the value of WS,

the room humidity ratio would change according to

GS * WS + GL * WA + QLL/x

WI = —

GS^ + GL^

This equation becomes inderminate when there is no air

supply or air leakage to or from the room. Theoretically the room relative humidity would reach 1007o soon

after the air supply or air leakage is stopped provided normal internal sources were still present. Under those conditions, seasonal value of WI to be used

would be that corresponding to the dew point temperature which would be approximately equal to the average

101a
wall surface temperature of the space.

The most important application of RMTMP is for taking

into account some of the performance characteristics

of the room's (or space's) heating and cooling systems where the evaluation of heating and cooling load

is linked to the system capacity. Presented in this

section is a sample algorithm to illustrate how RMTMP

can be used to account for the type of occupancy, temperature control scheme, and the system capacity. In

this illustration, the heating/cooling load will be

set equal to the maximum capacity of the system when

the calculated load at a given time is greater than

the maximum system capacity. The space or room temperature is then calculated on the basis of net load,

which is the difference between the calculated load

at a given design temperature and the maximum system

capacity. If, on the other hand, the space temperature falls within the prescribed upper and the lower

limits, the load is set equal to zero. The same procedure is applied to the latent load calculation. The

details of the algorithm is depicted in the flow diagram (Figure A-2 0). The nomenclature for the figure

is given in Table A- 12.

ATTIC

A Description of the Load Calculation for an Attic Space

In many cases the heating and cooling load in an attic space is affected strongly by the manner in which the attic conditions are maintained.

The non-ventilated attic space may be treated as a simple air space within

a roof structure and accounted for in the calculation of the conduction

transfer functions. Where the attic space is ventilated during the summer

to take advantage of the resulting natural cooling effect of the outdoor

air, it has to be treated somewhat differently. Since it is reasonable

to assume that the radiation heat exchange between the underside of the

roof surface and the attic is as significant as the ventilation air rate

in determining the attic thermal condition, RMTMP should be used. No additional algorithms are then required since all aspects covered in RMTMP

apply directly to the attic heat transfer calculation. Of course, the solar radiation through windows, and internal heat gain from lighting and

occupants would most likely be omitted. The floor should be treated as

having its exterior surface exposed to the environmental conditions of

the room below. The heat loss at the "exterior" surface of the floor then

becomes the heat gain to the room beneath the ceiling.

FIJ 1 outlines the calculation procedure for obtaining the necessary

shape factors where the attic has a gabled roof .-

A Simplified Procedure for Obtaining Approximate Cooling Load

by the Use of Weighting Factors

The procedure presented here was developed by Mitalas and Stephenson

of National Research Council of Canada"^^^-*— in order to expedite the

otherwise complex and time-consuming solution of the heat balance simultaneous equations. The rigorous solution similar to that described in

RMTMP was first obtained for typical rooms in commercial buildings with

pulse type excitations that simulate various heat gains. The solution

for these pulse excitations were then converted into new types of transfer functions called Weighting Factors. Weighting Factors developed for

typical office spaces of light, medium, and heavy constructions are shown

in Tables A- 13, A-14, and A-15 for solar heat gain with no internal shading devices; heat gain conduction through interior and exterior structure

components, solar heat gain with interior shading devices and all internal

sources except lighting; and the heat gain due to lighting. By multiplying these Weighting Factors to the history of respective heat gains in a

convolution scheme, similar to the way the conduction transfer functions

are multiplied to the temperature history, it is possible to calculate an

approximate cooling load.

to have previous values of heat gains as well as values of cooling loads.

INFIL

An Algorithm for Calculating Air Infiltration

It is well recognized that the air infiltration constitutes as much

as 30% of home heating load and a significant part of the load of nonpressurized commercial buildings. The air leakage of a building depends

upon the tightness of its exterior walls, windows, and doors, the wind

characteristics and temperature difference between the inside and outside, and to some extent how the building is operated with respect to

the opening and closing of its door.

The rate of air infiltration can be empirically expressed by

Q = e^A^AE^-^^N

where

Q : air flow rate

C: flow coefficient

A: flow opening area

N: pressure exponent

AP: pressure difference

Unfortunately it is very difficult to determine accurate values of flow

opening area and pressure difference for actual buildings, which consist

of complex air leakage passages. A limited amount of data are given in

the 1972 ASHRAE Handbook of Fundamentals for equivalent opening area of

typical windows, doors and walls. The pressure difference depends upon

the wind characteristics around the building and the temperature differ129a
ence between the inside and the outside of the building.

Compiled in this section is a methodology to approximately calculate

the pressure difference between a given space and its adjacent space including the outdoor. The basic mathematical principle involved is to attain a solution to a set of pressure difference equations of the following type:

where

l,k

N

l,k'

net air flow out of space 1

air exchange between space 1 and space k

flow opening area between space i and k

flow coefficient applicable to the air

flow between the spaces i and k

pressure exponent applicable to the flow

between the spaces i and k

A special computational routine is required to solve this set of simultaneous, non-linear equations.

As mentioned previously, air leakage through various openings such

as doors, windows, window frames, pinholes In the wall and service shafts

may be approximated by an equation of the following type:

130a
LEAK = 4000 * A * K * (DP) N

= C (DP) ** N

where

LEAK = air leakage in cu. ft per min,

A = opening area, sq ft

K = flow coefficient, dimensionless

DP = pressure difference across the opening, inches of water

N = pressure exponent, dimensionless

C = equivalent flow coefficient (EEC)

The values of K and N vary depending upon the type of opening. Moreover,

the exact value of A is not well known for many types of openings, such

as wall pinholes or cracks around the windows. Table A- 17 lists the values of Equivalent Flow Coefficient C and the flow exponent N for various

types of openings common to many buildings. These values are derived from

the air leakage data compiled in Chapter 19 "Infiltration and Natural Ventilation" of the 1972 ASHRAE Handbook of Fundamentals.

In the previous equations, unknowns are PI^ for k = 1, 2, 3,

... NF and PSE^ for k-1, 2, 3 ... NF provided that the pressures in all the shafts are assumed equal at a given floor

level.

Flow balance equations at the k-th floor (the individual

quantities come from equations 1-10 aboVe)

In all of above expressions, subscript k refers to the k-th floor and

subscript j refers to the j-th side of the building where the conven- tion is j = 1 (south), 2 (west), 3 (north), and 4 (east).

where CFMSPS^: ventilation air supplied at the

k-th floor in the shaft

CFMEXS, : air exhausted from the shaft at k

the k-th floor

These 2 ^ NF sets of flow balance equations must be solved

by an appropriate iteration technique to obtain the pressure

profiles in the building and in the shafts. Then the calculated pressure values are used to determine the air leakage

of the building.

Recently a comprehensive computer program that embodies the basic

algorithm described in this section was published by D. M. Sander and

G. T. Tamura of the National Research Council of Canada. The details

of the program are given in an NRC booklet entitled "A Fortran IV Program to Simulate Air Movement in Multi-Storey Buildings", DBR Computer

Program No. 35, (March 1973).

If this equation were for a service shaft, LEAKEL, would be replaced

by LEAKESj^.

2. If MO = 4, DAY is less than 25, DST = 0

If DAY is greater than 23, call WKDAY subroutine

If DAY is Sunday, DSTX = DAY

If DAY is less than DSTX, DST = 0, otherwise DST = 1

3. If MO = 10, DAY is less than 25, DST = 1

3. Repeat the following steps for ND times

lY = lY - lADD

If lY is greater than 7, lY = lY - 7

If lY is equal to 0, lY =7

If lY is less than 0, lY = lY + 7

4. Let MD = YR - N * 4

If m is equal to 0 IWK = lY

If MD is equal to 1 IWK = lY + 2

8. Let WKDAY = NDX

9. If this routine is going to be applied for the period outside

1901-2000, the following additional algorithms must be added

146a
KTEST = Last two digits of YR

If MO < 2 or KTEST = 0, KV = KV - 1

LTEST = Remainder of KV/4

KV = 4*LV + LTEST

If LTEST = 2, WKDAY = WKDAY + 1

= 0, WKDAY = WKDAY + 3

Otherwise WKDAY = WKDAY - 3* (LV - 4)

If WKDAY < 0, WKDAY = WKDAY + 7

If WKDAY > 7, WKDAY = WKDAY - 7

An alternate calculation sequence for WKDAY has been suggested*

PSY*

Various Algorithms for Approximate Psychrometric Calculations

The following symbols are used throughout the PSY subroutines:

DB: Dry-bulb temperature, F (determined in CLIMATE)

DP: Dewpoint temperature, F (determined in CLIMATE)

WB: Wet -bulb temperature, F (determined in CLIMATE)

t: Temperature, either DB, WB, or DP, F

PB: Barometric pressure, in. Hg (determined in CLIMATE)

H: Enthalpy of moist air, Btu per lb of dry air

HS : Enthalpy of moist air saturated with water vapor,

Btu per lb of dry air

PV: Partial pressure of water vapor in moist air, in. Hg

PVS : Partial pressure of water vapor in moisture saturated

air, in. Hg

V: Volume of moist air, cu ft per lb of dry air

W: Humidity ratio of moist air, lb of water vapor per

lb dry air

log(x): Natural logarithm of x

loglO(x): Common logarithm of x

When the exact Goff-Gratch method is required, algorithms described

in Reference 17 should be used. Tables A-19 and A-20 taken from that

reference list that the psychrometric properties calculated by the PSY

routines and the exact Goff-Gratch method, respectively. From examination of these tables it can be seen that the values calculated by

the PSY subroutines are in very good agreement with the values calculated by the exact Goff-Gratch method.

Weighting Factor Method of Calculating

Heating and Cooling Loads and Space Temperature^

This section was prepared by D. G. Stephenson and G. Mitalas of the

National Research Council of Canada for the ASHRAE Task Group on En

ergy Requirements for Heating and Cooling.

The weighting factor method is based on the assumption that the heat

transfer processes occurring in a room can be described by linear equations;

and thus that the superposition principle can be used for the calculation

of cooling load and space temperature. This means that the relationship

between any excitation (e.g., power input to lights) and the corresponding

component of the cooling load can be expressed in the form of a characteristic transfer function. Once all the transfer functions have been determined for a room, they can be used to calculate the response to any excitation. The weighting factors are a convenient way of representing these

characteristic transfer functions for a room: they relate the Z-transforms

of the excitations to the Z-transforms of the corresponding cooling load

components.

^ ^ 1, 2 / The Z- transform—^

When a continuous signal, f(t), is sampled at regular intervals of A,

the output of the sampling device is a train of pulses as shown in Figure

Bl, The Laplace transform of this output signal is

f (o) + f (A)e'^^ + f (2A)e"^^^ + (1)

sA

If Z is substituted for e , the transform of the output from the sampler

is

f(o) + f(A)z"-'- + f(2A)z'^ + (2)

This polynomial in Z is the Z-transform of the function f(t). The chief

advantage of this type of transform is that it can be obtained just by sampling the function at regular intervals: the successive outputs being the

coefficients of successive powers of Z in the Z-transform.

2b
If both the input and output of a system are expressed in terms of

their Z-transforms , the ratio of the output/input is a Z-transfer function

for the system. Assuming that such a transfer function, K(Z), can be found,

and that it can be expressed as the ratio of two polynomials in -Z

.

it follows that 0(Z), the Z-transform of the output that results from an

input represented by I (Z) is

0(Z) = K(Z) . I(Z) (4)

Both sides of this equation are polynomials so the coefficients of the

various powers of Z must be the same on the two sides of the equation.

Thus, equating the coefficients of Z gives

0 'b =1 - a +1 'ai+I ^ ' + . .

where the subscript n on 0 and I indicates the value of the function at

t = nA, i.e., 0^ is the coefficient of Z in the Z-transform 0(Z). This

expression relates the output at any time t = nA to the input at that time

and the values of the input and output at earlier times. The coefficients

a^, a,, ... and b^, b^ contain all the characteristics of the system.

3b
Cooling Load, Heat Extraction and Room Temperature

Using the Z-transfer functions approach, the cooling load is the

output that results from the input, which is the heat gain. The weighting factor sets are the transfer functions relating the cooling loads to

heat gains. The procedure for calculating cooling load is, therefore,

first to calculate the various components of the heat gain, and then to

combine them with the appropriate weighting factor sets to obtain the

cooling load. An expression like equation (5) is used to compute each

component of the cooling load.

The cooling load of a space depends on both the magnitude and the

nature of its excitations (i.e., outside air temperature, direct and

diffuse solar radiation, electric energy input to lights, etc.). The

resulting cooling load also depends on the location of the element that

absorbs the energy of the excitation. For example, the cooling load profile resulting from one unit of solar radiation absorbed by the window

glass is quite different from that of one unit of solar radiation absorbed by the floor surface. To shorten the computation of cooling load,

the heat gain must be subdivided into a limited number of components.

For example, the total heat gain by a space can be represented by the

following components:

(1) Heat gain through window. (HEATG and HEATG)

(2) Heat gain through exterior walls and roofs. (HEATX)

(3) Total power input to lights. (HEATIS)

(4) Heat gain through doors, partitions, underground walls

and floors, and due to internal heat sources other than

lights. (HEATDP)

4b
(5) Sensible heat gain due to infiltration. (HEATVS)

Each of these heat gain components is calculated on the basis of a

constant air temperature in the space. The actual air temperature generally deviates from this reference value, and consequently the rate of

heat extraction from the space, HE, differs from the cooling load. The

calculation of actual room air temperature and heat extraction rate is

the final step in the sequence of calculation: in this case, the previously calculated cooling load is the input along with the characteristics

of the air conditioning unit; and heat extraction rate and air temperature are the outputs. If this transfer function is expressed in the form

HE - CL ^ -j /I ^ " -i = Ex. z -^/l + Z y . z

or

HE^ = CL^ ^

where 6 is the deviation of actual air temperature from the reference

value used to calculate the heat gains.

The heat extraction rate given by equation (6) must match the rate

given by the characteristic of the air conditioning unit. For example,

a cooling unit with a simple proportional control system has a characteristic of the form

HE = C + D * 6 (7) n n

where

C = heat extraction rate of the unit operating in a room

at the reference temperature

5b
D = change in the rate of heat extraction caused by one

degree rise in room air temperature

Equations (6) and (7) can be combined to give an explicit expression

for 6 n V w

and then equation (7) can be used to evaluate HE . n Equation (8) can be used to calculate 6^ even if the cooling equipment is off: when the equipment is not operating, C and D are both zero.

Calculation of Room Weighting Factors

The calculation of the room weighting factors is based on the solu3 4/ tion of a set of heat balance equations for all the room air—^— (RMTMP),

A computer program for evaluating weighting factors has been developed by

the National Research Council of Canada—^, based on the procedure given

in Reference 4

.

Three different groups of room weighting factor sets are computed by

this program:

(1) The first group is very large, consisting of a set of

factors for each excitation at each surface.

(2) The second group combines all of the sets in group 1

that pertain to diffuse solar radiation into a single

set; it combines all of the sets for direct solar radiation incident on the room surfaces other than inside

window pane, floor, and furniture into another combined set; and lastly, it combines all the sets that

6b
pertain to excitation by the power supplied to the

lights into a single set,

(3) The third group of factors carry the consolidation

of the various sets of the limit : there is just one

set of factors for each component of heat gain.

It is not intended that the first group should be used directly for

room cooling or heating load calculations, as the second group give essentially the same results with considerably less computation—''. The

further simplication provided by the use of the third group require that

the following assumptions be made:

(1) That the heat gain through room envelope components

can be calculated with sufficient accuracy using combined inside surface heat transfer coefficient and

that the room weighting factors are the same for heat

gain through window, opaque outside wall, corridor

wall and a roof.

(2) That the fraction of the solar radiation absorbed

by the window glass and shade, and transmitted directly into the room as well as the portions absorbed

by various room surfaces and furniture are constant

during the day.

It is probable that the first assumption will not introduce signifi

cant errors; however, the second assumption is questionable. At this

time, research information is lacking to establish the possible magnitude of the error introduced by this assumption.

7b
The procedures given in this report to convert room excitation to

cooling load and heat extraction are based on the third group of room

weighting factors, i.e., RMRG, RMEIX, RMRT and RMITS. In addition, simplified procedures are given for the calculation of the RMRT and RMRTS

sets. If the highest possible precision is important, weighting factors

in the second group should be used.

NBSLD Data Forms

NBSLD in a Time-Sharing System

Recently, the General Services Administration of the federal government has subscribed to a time-sharing system called INFONET , which has

in turn made the use of NBSLD practical on a time-sharing system (see

figure on page 3c).

Entire subroutines and several main programs, which are parts of

NBSLD, have all been placed into INFONET and are now accessible to the

various government agencies through teletype terminals.

Some of the attractive features of the INFONET system are;

1. Data files for input and output can be created separately

from the execution of a main program such that computer

time does not have to be sacrificed by the slowness of

handling these data. (This is a common problem for heating/cooling load calculation programs.) An input data

file can be created, edited and stored for use by a main

program, while an output file of intermediate and detailed

results can be created in mass storage for later inspection without prolonging the computation time. When a final output is questionable, the analyst can examine the

input as well as the intermediate output in detail simply

by calling these data files independently.

2. After the execution of a program, the analyst can call

for specific values of variables without adding special

instructions in the main program to type out these variables .
3. The editing of a program as well as the data files can

be made in such a manner that the deletion, addition,

or alteration of statements or lines can be made without retyping the entire line.

4. All sub-programs are independently filed, compiled and

available to any main program in the same library by an

elaborate linking routine. Psychrometric routines, solar heat gain routines, transient heat conduction routines and weather data decoding routines can thus be

used by many different main programs.

This time-sharing system is therefore very well suited for design

calculations where many different alternatives for building construction

such as the area of glass, shading of the windows and thermal mass of

the internal structures are to be evaluated as to how they affect heating/cooling loads or energy requirements.

Introduction

This manual contains the input data forms with instructions for

preparing data needed to perform heating and cooling load calculations

using NBSLD.

In addition, the manual contains engineering data needed for the

computations so that the use of other handbooks or references are generally unnecessary. The required numerical data are to be filled into

blank spaces provided on each DATA SHEET and then each sheet can be used

directly at a computer terminal or to produce a data card if the program

is being run in "batch mode" at a central facility.

General Instruction

Figure C-1 shows the flow diagram or sequence for the data preparation.

Schedule Profile data sheets A, B, C and D are prepared for a building and are assumed the same for all zones or rooms within the building.

DATA SHEETS 1 through 3 are prepared for each different building,

thus need not be repeated for the analysis of rooms within the same buildDATA SHEETS 6 and 7 usually need to be prepared only for the first

room of the building, because other rooms that follow in the same building usually employ the same wall, roof, and floor constructions.

When two rooms have identical shape and construction and differ only

in orientation, the second room is considered to be rotated with respect

to the first room and requires only DATA SHEETS 4 and 5.

Wall /Roof /Floor -A

N: Number of layers of composition in a given wall/roof /floor construction.

By referring to the data of Table C3 (taken from the 1972 ASHRAE

Handbook of Fundamentals), give the following information for each of

the layers starting from the innermost layer to the Nth layer, which is

the outermost layer.

L: Thickness of the layer, ft.

K: Thermal conductivity of the layer, Btuh per (hr) (ft) (°F).

P: Density of the layer material, lb per cu. ft.

C: Specific heat of the layer material, Btu per (lb) (°F).

R: Thermal resistance value of the layer in (hr) (sq. ft,) (°F) per

Btu.

For the calculation where the ASHRAE weighting factor method is used

(ASHRAE = 1), the innermost layer is always the inside surface thermal

resistance. If ASHRAE = 0, omit the inside surface thermal resistance.

Outside surface thermal resistance is never used in all cases.

The value of R is to be given only when the layer has no apparent

thermal mass. If the value of L, K, P, and C are given, R should be zero.

If R is given, L, K, P, and C should all be zero, in particular, L should

be zero even if it is physically non-zero. For the ground floor, add a

finite thickness slab consisting of a 12" thick earth layer.

24c
Note: (1) At least one of the N layers should have non-zero values

of L, K, P, and C.

(2) If two or more consecutive layers have no thermal mass,

their thermal resistance values should be combined.

(3) If a particular wall is considered to have no appreciable thermal mass, or if it is desired not to consider

the thermal mass effect, data for this particular wall

should not be included in the data sheets.

(4) If roof is over attic space the innermost (first) layer

should be inside thermal resistance in all cases.

Weather Tape Handling

The use of Weather Data Tape 1440 provided by the National Climatic

Center may be made as follows:

1. Request the tape containing data for specified years from

the National Climatic Center

G. McKay or D. Calloway

Environmental Data Services

Asheville, North Carolina 28801

Telephone: (704) 254-0961

Remember that beginning January 1, 1965 a new program was

initiated for most Weather Bureau Stations reducing the

number of hourly observations being recorded from 24 to

8 per day. This format is not compatible with NBSLD as

it is presently written since it requires hourly weather

data. Note that the tape is 7 channel, 556 BPI density

and of even parity.

2. Have the tape mailed to INFONET computing center at the

following address:

Mr. K. Walls

Center 1 INFONET Division

Computer Science Corporation

650 North Sepulveda Blvd.

El Segundo, California 90245

3. Ask INFONET to assign a Volume number such as USOOl.

4. The tape 1440 is then decoded and stored into a weather

out on the terminal as they are processed and stored; otherwise zero.

The constants of WETDAT may be checked by a separate routine

WETAP by

I EQUATE 9 WETDAT

: WETAP

NDAY, NSKIP

where NDAY: Number of days for which the weather data

are to be displayed on the terminal.

NSKIP: Number of days to be skipped from the beginning of the file WETDAT.

62 c
When the use is made of WETDAT in any other program, it can be

read in the Fortran program as follows:

READ (9) DB, DP, WB, WS , PB, TC , NTOC, DAY, lYEAR, MONTH, ICITY

where DB, DD, WB, WS, PB, TC, and NTOC are all dimensioned 24

and represent respectively dry-bulb temperature, dewpoint temperature, wet-bulb temperature, wind speed, barometric pressure,

total cloud amount, and type of cloud.

* Data for U. S. stations extracted from Evaluated Weather Data for Cooimg Equipment Design, Addendum No. t. Winter and Summer Data, with the permiasion

of the publisher. Fluor Products Company, Inc., Box 1267, i-anla Ri>sa, California.

* Data complied from ortici;il ucatlier siatiuns. where hourly weatlier ubservaiions are niade by irained observers, and from other sources. Table 1 prepared by ASIIRAK Technical Coniniiitee ".2. W eather Data and Desicn Conditions. Percentage of umter design data show- the percent of 3-rnonth pi'nod. December iliroueh February, Canadian data are based on .January only. Percentage of surmner design data show tlie percent of 4-nionth period, June through treptember. Canadian

d^ta are based on July only. Also sec References 1 to 7.

\\ hen airport temperature tjbservatnns were used to develop dcsicn data. "AP" follows station name, and "AFB" follows Air Force Bases. Data for stations lollowed by "CO" came from office hjcations within an urban area and ^ene^ally reflect an influence of the surrounding area. Stations without designation can be

considered seminirat and may be directly compared witii most airport data. ^ Latitude is given to the nearest 10 minutes, for use in calculatmg solar loads. For example, the latitude for Anniston. Alabama is given as 33 4, or 33°40'. KIcvations arc ground elevations for each station as of 19Gt. Temperature readings are generally made at an elevation of 5 ft above ground, except for locations Oiarked r, indicatinii roof exposur*; of theriiionieier.

* Coincident wind velociiies derived fnjin approximately coldest 600 liours out of 20,000 hours of December through February data per station. Also see References 5 and 0. The four cias.^.iH.cutions arc: = Very Liaht, 7'' iiercent or mure of cold extreme hours <7 mph. M = Mo«'lerate, 50 to 74 percent cold extreme hours >7 mph.

J L = I^ight, 50 to r>'> percent cold extrt tue hours <7 mph. H = Hiii'i. 75 percent or more coid extreme hours >7 mph, and 6f) percent are >12 mph. The difference bet\\een the average maximum and average minimum temperatures during the warmest month.

Data for U. S. stations extracted from Evaluated Weather Data for Cooling Equipment Design, Addendum No. 1, Winter and Summer Data, with the penniasioD

of the publisher, Fluor Products Company, Inc., Box 1267, Santa Hoaa, California.

• D^ta compiled from official weather stationa, where hourly weather observationa are made by trained observers, and from other sources. Table 1 prepared by ASHRAE Technical Committee 2.2, Weather Data and Dcsicn Conditions. PercentaRe of u inter design data show the percent of 3-nionth period, Decenioer throuRn

February. Canadian data are based on January only. Percentage of summer desif^ data show the percent of 4-montn period, June through September. Canadian

data are* based on July only. Also see References 1 to 7. ^ When airport temperature observations were used to develop desisrn data, "AP" follows station name, and "AFB" follows Air Force Bases. Data for stations followed by "CO" came from otfico locations within an urban area and cenerally reflect an influence of the surrounding area. Stations without designation can be

considered semirural and may be directly compared with moat airport data.

* Latitude is given to the nearest 10 minutes, for use in calculatinc solar loads. For example, the latitude for Anniston. Alabama is given as 33 4, or 33*40'. Elevations are ground elevations for each station aa of 1964. Temperature readings are generally made at an elevation of 5 ft above ground, except for locations tn&rked r, indicating roof exposure of thermometer.

• Coincident wind velocities derived from approximately coldest 600 hours out of 20,000 hours of December through February data per station. Also ae« References 6 and 6. The four cLaasificalions are: VL « Very Light, 70 percent or more of cold extreme hours <7 mph. M ~ Moderate, 50 to 74 percent cold extreme hours >7 mph. L " Light, 50 to 69 percent cold extreme hours <7 mph, H = High, 75 percent or more cold extreme hours >7 mph., and 50 percent are >12 mph.

' The difference between the average maximum and average minimum temperatures during the warmest month.

Chapter; and Recommended Design Temperatures, Southern Calt/ornia, Arizona, Nevada, published by the Southern California Chaptar.

Earth Temperature Tables

for

Underground Heat Distribution System Design

The following Tables TG-1 through TG-11 were developed by applying

monthly average temperatures prepared by the U. S. Weather Bureau for

many localities in the United States to a technique described in the 1965

ASHEAE technical paper entitled "Earth Temperature and Thermal Diffusivity at Selected Stations in the United States" by T. Kusuda and P. R.

Achenbach. These temperature data are, however, for the undisturbed

earth. The earth temperature immediately under the building may be estimated by taking an arithmetic average of the building temperature and

the design earth temperature found in the appropriate table. For example, the floor on grade in the Washington, D. C. area may be treated as

a slab of 12" thickness with ground temperature of 70.5 °F if the room

temperature is 75 °F and the summer design TG is determined from the

data of Upper Marlboro, Maryland for ALPHA = 0.025 which is 66 °F.

Fortran Listing of NBSLD

Although the attached Fortran listing of the NBSLD routine basical

embodies the algorithms of Appendix A, some of the subroutines are considerably simplified if compared with the exact adaptation of Appendix

A.

It is cautioned also that the Fortran used herein is the UNIVAC ve

sion of Fortran V, which is somewhat different from the ANSI standard

Fortran.

...dul that's all changed now.

Today, increased energy costs—caused by in- creasing demand—boost the price of consumer

goods, fuel inflation, and hurt our balance of payments.

That's why conserving energy is a must today,

especially for you in the business and industry

community which uses two thirds of our nation's energy. Now . . . there's a book to tell you how to do

it. It's called EPIC—the Energy Conservation

Program Guide for Industry and Commerce. Pre- pared for you by the Commerce Department's

National Bureau of Standards in cooperation

with the Federal Energy Administration. EPIC is a comprehensive handbook that can

help you establish or improve an energy conservation program in your organization. Not only industry and commerce but also hospitals, universities, research institutes, ANY or- ganization that uses energy—and has to pay

the bills—will want a copy of EPIC. EPIC outlines in detail the steps in setting up

an energy conservation program.

It contains a checklist of more than 200 Energy

Conservation Opportunities—suggestions to save

U.S. DEPARTMENT OF COMMERCE / National Bureau of Standards FEDERAL ENERGY ADMINISTRATION / Conservation and Environment

energy in a dozen different areas. EPIC'S actual case histories of energy saving

actions help you estimate your potential for saving energy—and reducing costs. And EPIC contains much more—financial analysis procedures to evaluate projects, sources of information on energy conservation, engineering

data and factors, an energy conservation bib- liography.

Make EPIC part of your plan to control energy

use and costs. Make EPIC part of your contri- bution to using energy resources wisely ... so we can keep America working and growing.

To order your copy of EPIC, send $2.90 per copy (check, money order or Superintendent of Documents Coupons) to Super- intendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402.

bibliography or literature survey, mention it here.)

A comprehensive computer program called NBSLD, the National Bureau of Standards

Load Determination program, has been developed at NBS to reflect the time change of the

many building parameters which are pertinent to accurate estimation of energy usage for

heating and cooling. Current status of heating and cooling load techniques is reviewed.

Of general interest are unique features of NBSLD which are not available in existing com- puter programs. A summary of various subroutines of NBSLD is given along with the detailed procedures for them. These subroutines constitute the recommended subroutine algorithms of the ASHRAE Task Group on Energy Requirements. Complete Fortran listing of

NBSLD and data preparation forms are given for those who wish to use the program. The

NBSLD computation is on the basis of the detailed solution of simultaneous heat balance

equations at all the interior surfaces of a room or space. Transient heat conduction

through exterior walls and the interior structures is handled by using conduction transfer functions. The use of heat balance equations, although time consuming in calculation, can avoid the vagueness and uncertainties inherent in the more popularly used

weighting factor approach. In addition, it is more accurate for a specific building design.
