ABSTRACT

This report provides a life-cycle cost-benefit analysis of several

alternative methods for insulating 8" (200 mm) concrete masonry walls

in new single-family residences. In addition, a cost-benefit analysis

for insulation in wood-frame walls is provided, consistent with the

assumptions used in the masonry wall analysis. A dynamic load simulation

model, NBSLD, was used to calculate the heating and cooling requirements

for a 1176 square foot (110 m ) house with different levels of thermal

resistance for both wall types in eight geographic locations. These

data are used to calculate the reduction in annual heating and cooling

requirements due to several different types of insulation in the cores

and furring spaces of the masonry wall and the cavities of the wood-frame

wall.

Economic analysis is applied to determine estimates of life-cycle

savings from insulation for different locations and furnace types in

order to determine the most cost-effective insulation level. In general

it is found that the maximum economically justifiable level of insulation

in the masonry wall is considerably lower than for the wood-frame wall

because of the significantly higher cost of insulating masonry walls.

Key words: Building economics; energy conservation; insulation; life-cycle

cost analysis; masonry construction; space heating and cooling

requirements; thermal mass.
1.0 INTRODUCTION

The Center for Building Technology at the National Bureau of Standards is currently conducting research on the thermal performance of

exterior walls of residential buildings, with emphasis on masonry wall

construction, in order to assess the economic benefits and costs of

• • • •

jSj* alternative insulation strategies. This research has been sponsored by

the Department of Energy (DoE). The Department of Housing and Urban

Development-Federal Housing Administration (HUD-FHA) has supported one

phase of this study to provide information needed in the development of

their new Minimum Property Standards (MPS) for residential buildings.

This report covers that phase of the study.

This report provides specific information requested by HUD-FHA,

along with the basic methodology and data used to generate these results.

Further description of the methodology and more extensive data and

results will be made available upon the completion of the overall

research project and publication of the final research report for DoE.

The major objectives of the NBS research in insulation strategies

for exterior walls are to determine the extent to which insulation in

alternative wall configurations is cost effective on a life-cycle basis;

to develop insulation guidelines based on a life-cycle-cost-minimization

objective; and to establish the sensitivity of these guidelines to climate, fuel cost and insulation costs on a local basis. These objectives

* Note: Metric (SI) Units have been included in this report for reference

purposes, in line with the policy of the National Bureau of Standards. Rounding has been applied to reflect equivalent precision.

are consistent with recent policy decisions of EUD-FHA in updating their

MPS for single family residences based on the life-cycle-cost effectiveness of a number of conservation measures for reducing space heating and

cooling requirements. Moreover, they are consistent with recent DoE

decisions regarding the use of economic analysis in the development of

building energy performance standards for buildings.

Cost-effective strategies for increasing the thermal performance of

wood-frame and masonry walls in the same climate and for the same cost

per Btu of heat delivered to (or removed from) the conditioned space

might be expected to differ for two distinct reasons: (1) the reduction

in annual heating and cooling requirements due to an equal decrease in

U-value for the walls may be different and (2) the cost of reducing the

U-value for these two wall types may be different.

The first reason is related to the thermal response, or time-delay

properties, of the heavier wall which tends to dampen the effects of climate on space cooling and heating requirements. The extent to which this

affects the savings from an equal decrease in U-value will be seen later

in this report. The second reason is a result of the 3-1/2" (89 mm) stud

space in the wood-frame wall which provides a greater space for low-cost

insulation materials than the typical 3/4" (19 mm) furring space, and, in

some cases, open cores, of a masonry wall. In order to minimize the

reduction of usable floor space due to higher levels of insulation on

the inside of the dwelling unit, low conductivity, but relatively expensive (e.g., polystyrene and isocyanurate) insulation materials are often

used in masonry walls at a considerable cost difference over typical

2
insulating materials used in wood-frame construction (e.g., fiberglass

blanket). Alternatively, wood framing can be added inside the masonry

wall together with more conventional fiberglass insulation materials.

However, the increased cost of both the framing and the extension of end

walls to maintain an equivalent inside floor area must be incorporated

into the cost analysis. Insulation on the outside of the exterior walls,

while somewhat superior from a thermal performance is not as cost effective

as insulation on the inside, since a protective covering must be installed.

Such a covering would also negate the benefit of low exterior maintenance

characteristic of masonry materials. (Insulation in the cavity of a

brick and block cavity wall is not considered in this report although

it will be examined in a subsequent, more comprehensive report to DoE.)

2.0 SCOPE

HUD-FHA has requested that NBS examine the cost effectiveness of

several alternative insulation strategies for masonry walls. In particular, reflective air spaces, rigid isocyanurate insulation, and rigid

polystyrene insulation are to be examined with and without core insulation (perlite) in an 8

n (200 mm) block wall with 3/4" (19 mm) furring

strips and 1/2" (13 mm) gypsum wallboard on the inside. The exact specifications of the insulation strategies to be examined, as specified by

HUD-FHA, are shown in Table 1. There are nine different insulation

systems specified, for use with 8" (200 mm) block walls. In addition,

the sponsor asked NBS to evaluate the cost effectiveness of R-ll, R-13

and R-19 (R-metrxc: 1.9, 2.3 and 3.3) insulation in wood-frame walls,

using the same basic assumptions and modeling procedures. Composite or

cavity brick and block walls, which are more common than 8" (200 mm)

block walls in most parts of the U.S. other than Florida and the Southwest, are not examined in this report.

Previous NBS analysis of the cost effectiveness of a number of

conservation measures in wood-frame housing was used by HUD-FHA in

developing its most current revision of the MPS. In order to maintain

consistency with this previous work, the sponsor asked that the same

basic approach be used. This has been accomplished to the extent that

it matched the objectives of the ongoing BoE-sponsored research. The

only parameter that was significantly changed from the previous NBS

analysis for the sponsor is the design of the floor to simulate thermal

mass on the inside of the structure. This will be explained in greater

detail in the following section. Because this study is intended to

examine the cost effectiveness of wall insulation, the specification of

other shell components was held constant in each climatic location. However, ceiling insulation levels and glazing specifications (e.g., single,

double, triple) were adjusted in each location to conform as closely as

possible to the proposed MPS. The eight locations to be used in examining

the sensitivity of insulation cost effectiveness, the number of long term

heating and cooling degree days, and the attic insulation and window

glazing specifications used in each location are shown in Table 2.

3.0 MODELING THE WALLS FOR THERMAL ANALYSIS

Table 3 provides the basic measurements of the 1176 square foot

(110 m ), one-story ranch house used in the simulation of heating and

cooling requirements typical of a house of this style. This prototype

house is modeled after the "compact" ranch style house proposed by

S. R. Hastings [1] for use in energy conservation research. The house

is modeled as one big room as it has been determined through previous

analysis at NBS [2] that this more closely simulates actual thermal

performance than modeling uncoupled rooms within the house. (Coupling

of rooms has not yet been properly simulated). The floor is modeled as

'£c a concrete slab weighing 20,000 lbs (9070 kg) and is essentially adiabatic

(i.e., does not transmit heat into the ground.) This concrete floor is

meant to represent the internal mass of the house, including partition walls,

fixtures, and furnishings, rather than a more typical slab on grade.

The base house is oriented with the long walls facing north and south.

z

)

face south and 55 square feet (5.1 m") face north. (The glass to gross

wall area ratio is approximately 11 percent.) In addition, in three locations the masonry house is turned 90°, with the larger glass area facing

west, in order to determine the impact of orientation on the energy savings

from insulating the walls. All glass area is assumed to be 50 percent

shaded between May and September. The direct solar heat gain is modeled

This is accomplished by modeling a very high thermal resistance beneath

the slab in order to isolate it from the ground temperature.

so that 90 percent is distributed directly to the floor, with the remaining

10 percent evenly distributed to the other interior surfaces. (This solar

distribution in effect simulates the solar gain of interior partitions and

furniture rather than of the inside of the exterior surfaces of the room.)

Operational assumptions are shown in Table 4. Note that a night setback from 68 to 60°F (20 to 15.5°C) is assumed during the heating season.

This night setback, together with the internal mass and south facing

windows gives the house some advantage from a ’'passive'* solar aspect.

NBSLD [2,3], the NBS Load Determination program, was used to simulate the heating and cooling loads of the prototype house on an hour-byhour basis for an entire year. Test reference year tapes were used to

provide hourly climate data for the locations considered, consistent with

the data requirement of NBSLD. Because NBSLD can calculate the thermal

response of the walls to a relatively high degree of accuracy, this

program is well suited for the thermal analysis in this report. In addition, it has been successfully validated in a number of studies at NBS

and elsewhere [4, 5, 6].

In calculating the thermal performance of the 8" (200 mm) block wall,

the core section of the block is modeled separately from the web section.

NBS analysis has shown that this approach is superior to modeling the

wall as homogeneous in mass and thermal resistance. This latter approach

is faster in terms of computational effort but exaggerates the thermal

response characteristics of the wall. Similarly, wood-frame walls were

modeled with studs considered separately from cavities.

thus the 60 percent upper bound only applies during periods when the air

NBSLD was used to perform extensive simulations of the effects of

insulation in an 8" (200 mm) masonry block wall and a conventional woodframe wall. Washington, D. C., which has annual heating and cooling

requirements that are near average for the U.S., was used in these simulations to demonstrate certain effects of various insulation levels that

can be used to simplify the requirements for simulations in other climates.

In particular, the validity of using U-values to linearly interpolate

between annual heating and cooling requirements, as calculated by NBSLD

analysis, in order to estimate the heating and/or cooling requirements

of alternative insulation levels in the same wall type, was demonstrated.

Because the mass of alternative insulation types is insignificant relative

to the mass of the wall itself, the results of the NBSLD analysis can be

used, within reason, for estimating the effects of any type of insulating

material practical for the basic wall constructions examined.

Tables 5A and B contain the data points developed through NBSLD analysis of thermal insulation in the furring space of 8" (200 mm) block walls,

with and without perlite insulation in the cores of the blocks, respectively.

In addition, data points from the analysis of fiberglass insulation in a

wood-frame wall are shown in Table 5C. Table 5D contains the data points

for the 90° rotation of the 8" (200 mm) block house in Madison, Phoenix,

and Washington, D.C. It should be noted that the U-values in Tables 5A,

B, and D do not correspond exactly to the HUD-FHA values shown in Table

1 because the former are based on more generalized material specifications.

Total cooling requirements (C) in this report have been divided into

two parts: cooling requirements for all hours in which the outdoor dry bulb

temperature is 78°F (25.5°C) or greater (C+), and cooling requirements for

all hours in which the outdoor dry bulb temperature is below 78°F (25.5°C)

(C-). (Note that C = C- + C+.) If windows are assumed to be closed at all

times, C is the best representation of annual cooling requirements. If windows

are opened for natural ventilation when the outdoor temperature is below

78° (25.5°C), C+ is the best representation. In fact, actual operating

practices are usually somewhere between these two extremes. For example,

during spring and fall windows and doors may be left open for natural

ventilation more frequently than during the summer months. Noise, humidity,

air pollution, and security considerations may encourage leaving windows

closed more than they might be otherwise, especially in urban areas.

The data points in Tables 5A, 5B, and 5C are shown graphically in

Figures 1-8 for the eight cities examined. Visual examination of these figures

shows that a change in wall U-value has a very significant effect on heating

requirements while having a minimal effect on cooling requirements. In

general, the masonry walls perform slightly better than wood-frame walls

for the same U-value in the range of 0.05 to 0.15 (U-metric 0.28 to 0.85),

which is the range of major interest. The effects of mass in reducing

energy requirements appear to be most noticeable with respect to the cooling

requirements in hours when the outdoor temperature exceeds the thermostat

setpoint (78°F (25.5°C)). For cooling hours in which the outdoor temperature

is lower than the thermostat setpoint, the wood-frame wall generally

(although not in every case) outperforms the masonry wall. The summation

of C+ and C- data generally shows that the masonry walls have a slight

(1-5 percent) advantage over wood-frame walls when both are interpolated to a

U of 0.1 Btu hr“^ ft”^ (U metric = 0.57 W/m^ • °K). Comparative

performance of masonry and wood-frame walls at this U-value is shown

in Table 6. However, it must be stressed that the purpose of this

report is to determine the cost-effective level of insulation in each

system, not to determine the U-value that provides equal thermal performance.

Comparison of Tables 5A and 5D show that the house rotated 90°

to the west has somewhat higher heating and cooling requirements than

the base houses for the same wall design. However, differences in the

energy savings due to reductions in wall U-value are not significant

enough to warrant further analysis.

Because the effects of insulation on cooling loads are generally

quite small, and because these effects vary from negative to positive

depending on the way the house is operated, it is recommended that,

except in the case of Phoenix, only the heating saving be considered in

the final economic analysis of both masonry and wood-frame walls. Since

the insulation in the walls of the house in Phoenix has a distinct beneficial effect even with windows always closed, the benefits of wall

insulation in reducing annual cooling requirements should be recognized

in that climate. A sensitivity analysis is performed to determine the

effect of this recommendation on economic levels of insulation. This

will be discussed later in this report.

Because of the generally linear nature of the performance data for each

wall type as a function of its U-value, and because the results of the NBSLD

analysis are not sensitive to the type of insulation material examined, but

rather only to its thermal conductivity and thickness, interpolation between

the data points actually examined and any other U-values within this range

can be accomplished with considerable confidence. The data points were

generated using non-ref lective air spaces, reflective air spaces, and several

levels of rigid foam insulation. This approach allows extreme flexibility

in analyzing different insulation materials at different thicknesses as long

as they are considered for the same wall type and same placement within the

wall itself. The polystyrene insulation levels examined for the sponsor are

for the most part the same as used in establishing the data points with NBSLD,

although minor differences in the wall U-values occur due to minor differences

in material specifications. The NBSLD data points are interpolated to provide

results which correspond exactly to the HUD-FHA wall specifications. The

analysis of the thermal performance of isocyanurate insulation is also

accomplished by interpolating the NBSLD data points, using the thermal properties of the isocyanurate insulation provided by HUD-FHA in Table 1.

For example, using the highest and lowest U-values for 8" (200 mm) block

walls in Washington, D.C., .2417 and .0693 (U-metric 1.37 and 0.39), interpolation for U = .1443 (U-metric = 0.82) results in annual heating and

cooling requirements, respectively, of 14.99 and 16.13 x 10° Btu (15.82

and 17.02 GJ). NBSLD calculations at U = .1443 (U-metric = 0.82) result

in Annual Heating Requirements and Annual Cooling Requirements of 14.92

and 15.94 (15.74 and 16.82 GJ), respectively. In general interpolations

are made over a considerably narrower range.

31
The effects of the alternative insulation specifications on actual

energy savings are analyzed for four heating system types: gas furnace,

oil furnace, electric resistance furnace, and heat pump. Seasonal performances assumed for all systems in each location are shown in Table 7. The

seasonal performances of combustion heating systems are based on an analysis by Chi, Kelly, and Didion of good quality gas and oil furnaces in a

range of climates [7]. In all cases an electric pilot light is assumed.

In locations other than Jacksonville, Tampa, and Phoenix, a stack damper

is assumed to be installed on gas furnaces. (A stack damper is not likely

to be cost effective in climates with small annual heating requirements.

Stack dampers for oil furnaces are not commonly available at present.)

Note that there is some small variation, by climate, in the seasonal performance of combustion furnaces, consistent with NBS research results. Heat

pump seasonal performance data are based on research by Gordian Associates [8]. In most cases interpolations were made from the Gordian data

using heating degree-day data for the locations examined.

The seasonal coefficient of performance (COP) for central air conditioners varies little by climate. The COP of 2.3 is approximately equivalent

to an SEER (seasonal energy efficiency ratio) of 8.0, consistent with most

manufacturers" middle-of-the-line products.

4.0 TECHNIQUES OF ECONOMIC ANALYSIS

In order to establish the cost effectiveness of the alternative

insulation levels to be examined, a life-cycle analysis of the insulation

costs and savings is performed. That is, the present value of all energy

savings over the life of the wall, in dollar terms, due to each improvement

in insulation is compared with the cost of that improvement to determine

whether or not it is cost justified. Only if the incremental savings of

additional levels of insulation, over the next lower level, are greater than

or equal to their incremental cost can those additional levels be cost justified on a life-cycle basis.

Consistent with the previous economic analysis of conservation measures

performed by NBS for the HUD-FHA, a 30-year life, 10 percent (nominal) discount rate, and regional fuel price projections published by DoE [9] were

used. The 30-year life is based on the length of a typical mortgage, which,

in effect, testifies to the fact that the expected life of the average house

and, by inference, the wall insulation, is at least that long.

Life-cycle savings (LCS) are computed as follows:

(e.g., therm = 10, gallon of oil = 7.14, kWh = 293), and

are the present worth factors for the heating fuel and

kWh, respectively.

For metric equivalent, use GJ instead of lO^Btu.

34
DoE projections for regional energy prices are based on the "Trendlong" series with an assumption of 5 percent increase in oil constant dollar

costs each year. Energy costs are shown in Table 8.

The present worth factor (PWF) is critical to the life-cycle-cost

analysis because it converts first-year dollar savings to present-value,

life-cycle savings. The PWF is a function of the life (30 years), discount

rate (10 percent) and projected rate of fuel price increases. Since the

projected rate of fuel price increases published by DoE vary by fuel type

and region, different PWF are used for each city and heating fuel used.

The PWF for each city and fuel type used in the economic analysis are shown

in Table 9.

Insulation costs for masonry walls were based on the 1978 Means'

Building Construction Cost Data [10] where practical. The material cost of

isocyanurate was taken from the 1978 "Masonry Cost Guide” [11], but the

insulation cost and overhead and profit factors are the same as used for

polystyrene in Means. The costs for R-ll and R-13 (R-metric 1.9 and 2.3)

fiberglass insulation in a nominal 2" x 4" (38 x 89 mm) wood-frame house

were based on NAHB Research Foundation data provided under contract to NBS.

These costs are slightly lower than Means but are probably more typical of

current residential construction. The cost of the polystyrene sheathing is

based on the additional material cost net of the cost of normal asphalt

impregnated sheathing, with no additional installation cost, since the former

essentially substitutes for the latter. All cost data are shown in Table 10.

In order to determine the sensitivity of the results to installed insulation

costs, a second analysis with costs increased by 25 percent was made.

37
If an increase in the insulation level of the wall can reduce peak

heating or cooling loads to the point where smaller heating and cooling

equipment can be used* the dollar savings in equipment procurement, if

any, should be deducted from the cost of the insulation. While a substantial reduction in peak heating requirements is realized, in general the

savings in heating equipment cost is likely to be insignificant. The

reduction in peak cooling loads due to an additional increment of insulation is generally small (less than 1000 Btu/h (300 W)) and thus no reduction in cooling equipment tonnage is expected. (Cooling equipment is

typically sized in approximately 6000 Btu/h (1800 W) output capacity

increments.) As a result, no increase in the wall insulation level above

the maximum cost-effective level determined through the analysis of energy

savings alone is generally found to be cost effective due to the additional

savings from reductions in equipment sizing. (It is possible to construct

a specific example where additional insulation would be cost effective

because of a reduction in equipment size made possible by the reduction

in design loads. However, no generalization can be made from such an

example .

)

A summary computer program was developed to allow the user to perform

the incremental life-cycle-cost analysis of alternative insulation strategies for any wall type on which thermal performance data are available.

The user enters the base (i.e., uninsulated) U-value of the appropriate

wall system type, the name, corresponding wall U-value and total cost for

each of the increasing insulation levels to be analyzed. Savings due to

reductions in heating requirements are always calculated. However, the

38
user can specify whether to consider (1) cooling savings based on cooling

only when the outdoor temperature is above the thermostat setpoint, (2)

no cooling savings due to insulation, or (3) net cooling savings (losses)

regardless of the outdoor temperature (i.e., no natural ventilation).

The program uses the thermal performance data developed with NBSLD analysis for the appropriate wall system in order to interpolate the thermal

performance of the insulated wall systems to be analyzed. It then determines the incremental change in heating and cooling requirements (as

specified by the user) due to each additional level of insulation. Using

the method shown above it calculates the incremental life-cycle heating

and cooling savings and compares their sum to the incremental insulation

costs. Both the incremental net savings (incremental savings minus incremental cost) and cumulative net savings to that point are shown. The

level of insulation with the greatest cumulative net savings is the most

cost-effective level for the climatic and cost conditions considered.

Any additional level(s) of insulation will not provide incremental

savings greater than the costs incurred. If two or more alternative

methods of insulating the same wall are to be evaluated, the method with

the greatest cumulative net savings is the most cost effective.

5.0 RESULTS OF THERMAL AND ECONOMIC ANALYSIS

In order to evaluate the cost effectiveness of the insulation measures

specified by the sponsor, the analysis was divided into five insulation

groups, designated as:

HUD 1 - insulation of hollow 8" (200 mm) block walls with reflective

air space and isocyanurate (B3, C3, "EXTRA")

39
HUD 2 - insulation of hollow 8" (200 mm) block walls with reflective

air space and polystyrene (B3, D3, F2)

HUD 3 - insulation of 8" (200 mm) block walls with cores filled,

reflective air space and isocyanurate (B4, C4)

HUD 4 - insulation of 8" (200 nun) block walls with cores filled,

reflective air space and polystyrene (B4, B4, F5)

HUD 5 - insulation of wood-frame walls with fiberglass ( R— 1 1 and

R-13) and polystyrene sheathing (R-19) (R-metric 1.9,

2.3 and 3.3).

Each group was analyzed to determine the most cost-effective level

of insulation, starting with an uninsulated wall with a non-ref lect ive

air space. All cases were analyzed with the assumption of no cooling sav

ings. A number of cases, including Phoenix, Tampa, and Jacksonville were

analyzed where the effects of insulation on cooling requirements were cal

culated as well in order to determine whether this had any significant

effect on the results. Computer printouts for each run made are included

in Appendix A (no cooling savings), Appendix B (cooling based on windows

closed) and Appendix C (cooling savings above 78°F (25.5°C) outdoor

temperature). All printouts in the appendices are calculated using the

base insulation cost data shown in Table 10. Tabulations of these runs

are presented in Table 11. The tabulations show the optimal (i.e., most

cost-effective) level of insulation for each group along with its corresponding life-cycle net savings. All data in Table 11 are based on no

cooling savings from insulation, except for Phoenix, where the data are

based on the thermal analysis with windows closed at all times (C). In

other cities, the assumption of no cooling savings generally provides

the same results in terms of optimal insulation levels as the two other

assumptions regarding cooling savings. Table 12 presents similar tabulations based on the 25 percent increase in insulation costs.

In the cases where insulation is added to hollow block walls, the

foil-backed gypsum wallboard over the 3/4" (19 mm) airspace (B3)* appears

to be the most cost-effective insulation level for gas, oil, and heat

pump in the milder climates while either the 1/2" (13 mm) isocyanurate

with foil-backed gypsum board and air space ("EXTRA") or the 1-1/2"

(38 mm) polystyrene insulation (F2) appears cost effective for most appli

cations in the colder climates and where an electric furnace is used.

The use of either 3/4" (19 mm) isocyanurate (C3) or 3/4" (19 mm) polystyrene (D3) is never cost effective when compared to the 3/4" (19 mm)

reflective airspace (B3) because the additional savings are relatively

minor and the additional cost relatively high. In the cases where the

cores of the 8" (200 mm) blocks are filled with perlite insulation, the

foil-backed gypsum wallboard appears most cost effective in all but the

coldest climates with an electric furnace. However, the cumulative net

savings for the cases where core insulation is examined (HUD 3, HUD 4)

are less than those for the cases with no insulation in the cores (HUD 1

and HUD 2). This shows that it is generally more cost effective to

insulate the inside wall and leave the cores empty. In general, the

8" (200 mm) block wall with 1-1/2" (38 mm) of polystyrene insulation and

hollow cores (F2) has a lower U-value and higher net savings than the

same wall with 1/2" (13 mm) isocyanurate insulation and a reflective air

space (EXTRA).

Potentially, condensation on the foil-backed gypsum wallboard during

the air conditioning season in locations such as the Gulf Coast, or dust deposits in the drier regions of the U.S. could degrade the longterm thermal performance of this insulation technique. However, these

phenomena have not been widely noted as problems in the field.

45
In the colder climates, even more insulation than has been examined

may be cost effective on the inside. However, beyond 1-1/2" (38 mm)

insulation the additional cost of the insulation should be adjusted to

offset the effects of the reduced living area. This adjustment can be

made by determining the additional cost of moving the end wall outwards

by several inches in order to maintain an equivalent interior area.

A minimum of R-ll (R-metric 1.9) insulation in wood-frame walls

appears cost effective in all locations except Tampa and in Jacksonville

with gas heat or a heat pump. R-19 (R-metrioc 3.3) insulation appears cost

effective in all electrically heated houses except in southern areas and

in gas-, oil-, and heat pump-heated houses in northern areas of the U.S.

Similar patterns appear in the analysis using installed insulation

costs increased by 25 percent. Foil-backed gypsum is indicated in slightly

colder climates than indicated using the lower costs. Results for insulation

in wood-frame walls using the higher insulation costs are nearly identical

to those based on the lower costs.

Sensitivity analysis to the house orientation was performed in order

to determined the effects of rotation on the cost effectiveness of the insulation in masonry walls. The house was rotated 90° to the west, so that the

long walls ran north-to-south and the largest window exposure was to the west

instead of south. NBSLD simulation of the 8" (200 mm) hollow block wall

were made for Phoenix, Washington, and Madison. Annual heating and cooling

requirements were increased by as much as 17 percent and 12 percent respectively over the same house in its original orientation. The savings due to

46
insulating the exterior walls of the rotated house were slightly, but

not significantly, greater than those resulting from insulation of the

walls in the original orientation. As a result, the maximum costeffective level of insulation did not change with respect to building

orientation. The economic analysis for these three cities are provided

in Appendix D.

6.0 CONCLUSIONS

Although the energy savings due to an equivalent decrease in U-value

for masonry walls are nearly the same as those for wood-frame walls, the

maximum economic level of insulation is significantly lower for the masonry

walls. This is due to the fact that the insulation of masonry walls is

significantly more expensive than insulation in wood-frame walls, thereby

reducing the cost effectiveness of the insulation. As a result, houses

with optimally insulated 8" (200 mm) concrete block walls (100 pcf,

O 1600 kg/mJ

), are likely to use somewhat more energy for heating each year

than optimally insulated wood-frame houses and slightly less (1 to 5 percent)

for cooling.

In extreme southern climates, where heating requirements are small,

foil-backed gypsum board with 3/4" (19 mm) air space is generally the

maximum cost-effective insulation level in the 8" (200 mm) block wall.

Except in climates like that of Phoenix, which tends to have extremely hot

days, insulation has only marginal effects on cooling requirements and may

actually increase cooling requirements if natural ventilation is not used

when adequate for cooling purposes.

47
In general, insulation in the cores of the 8" (200 mm) blocks is

not as cost effective as insulation on the inside wall surface. This

is because of the high cost of this method and the low change in overall

| thermal transmittance relative to that for insulation on the inside

surfaces. Although the analysis was limited to a maximum of 1-1/2"

(38 mm) of rigid foam insulation in the wall cavity, more may be cost

effective in the colder climates, especially if electric heat is used.

It should be recognized that the results discussed in this report

are limited in scope in that only an 8” (200 mm) block wall with a concrete

O density of 100 pcf (1600 kg/m ) and a conventional wood-frame wall were

examined in conjunction with a limited analysis of insulation strategies.

The key to improving the cost effectiveness of insulation in masonry

walls appears to lie in finding lower cost methods for insulating these

walls, since the savings from the insulation are quite similar to those

for wood frame construction. A more complete analysis of masonry wall

types and insulation strategies will be included in the final report

to be prepared for DoE later in 1979.

16. ABSTRACT (A 200-word or less factual summary of most significant information. If document includes a significant bibliography or

literature survey, mention it here.) This report provides a life-cycle cost-benefit analysis of several alternative

methods for insulating 8" (200 mm) concrete masonry walls in new single-family

residences. In addition, a cost-benefit analysis for insulation in wood-frame

walls is provided, consistent with the assumptions used in the masonry wall

analysis. A dynamic load simulation model, NBSLD, was used to calculate the heating and cooling requirements for a 1176 square foot (110 m^) house with different

levels of thermal resistance for both wall types in eight geographic locations.

These data are used to calculate the reduction in annual heating and cooling requirements due to several different types of insulation in the cores and furring spaces

of the masonry wall and the cavities of the wood-frame wall.

Economic analysis is applied to determine estimates of life-cycle savings from

insulation for different locations and furnace types in order to determine the most

cost-effective insulation level. In general it is found that the maximum

economically justifiable level of insulation in the masonry wall is considerably

lower than for the wood-frame wall because of the significantly higher cost of

insulating masonry walls.
