ABSTRACT

A set of measured residential data has been culled from three larger data sets

for use in the testing and verification of building energy analysis programs.

The data consist of hourly values for heating/cooling system performance and

weather conditions that are sufficient in detail, it is believed, for all

existent computer programs. These data have been encoded onto a magnetic tape.

In addition, general information has been collected on the houses, occupants/

occupant use, and heating/cooling systems.

Keywords: building energy analysis program; data tape, measured hourly data;

testing and verification.

SI Conversion

In view of the presently accepted practice of the building industry in the

' United States and the structure of the NBS Load Determination computer

program used in this report, common U.S. units of measurement have been used

throughout this report. In recognition of the position of the United States

as a signatory to the General Conference of Weights and Measures, which gave

official status to the metric SI system of units in 1960, appropriate conversion factors have been provided in the table below. The reader interested in

making further use of the coherent system of SI units is referred to:

INTRODUCTION

1.1 BACKGROUND AND PURPOSE

With the development and widespread use of computer programs for energy analysis

of buildings has come recognition of the need for reliable measured data for use

in the testing and verification of these computer programs. For the most

part, in the past, computer programs have been verified by using hypothetical

and measured data. The reason for the infrequent use of measured data has

been a lack of data since few buildings have sufficient instrumentation to

monitor the data parameters that are needed for most computer programs. This

situation has changed during the last several years with data becoming available

from major data collection efforts for both residential and commercial buildings

[1-5]. However, some of these data prove unusable. Some typical reasons for

this are:

1. Bad or missing data - due to malfunctioning sensors or data acquisition

systems;

2. Part or all of data monitoring system shut down - due to repairs or normal

maintenance;

3. Data anomalies - due to fluctuations in data caused by unmeasured parameters

(e.g., increase in house hourly energy requirements for a period of time

because of a temporary but unmonitored window opening)

.

While unusable data are quite understandable, it proves very annoying to the

researcher who must use the data, since it usually appears randomly throughout

the data set. Therefore, the researcher may spend an inordinate amount of time

culling a subset of reliable data from the total available data set. The purpose of this effort is to provide a cross-section of reliable energy performance

data for residential housing that can be quite readily used in the testing and

verification of building energy analysis programs.

The data derived in the report and accompanying data tape came from references

[1-3]. The data in reference 1 came from an Electric Power Research

Institute (EPRI) study of 5 single-family detached houses located in California,

New Mexico, Arkansas and New York. The data in reference 2 came from a National

Bureau of Standards (NBS) study of 3 single-family detached houses in Houston,

Texas. The data in reference 3 came from a Department of Energy (DoE) study of

25 townhouses in Twin Rivers, New Jersey. The data contained in the data tape

consist of hourly measurement of house energy use and weather conditions. Contained in the report are thermal physical and occupant /occupant-use information

about the house.

1.2 APPROACH

As is the case with any effort to select a subset of data from a larger set of

data, one must establish certain guiding criteria. It was decided that since

the goal of this study was to select a limited amount of measured data that

would have widespread usefulness and since a sophisticated statistical analysis

1
of the approximately 2.5 million data points was beyond the scope of this

study, that the guidelines that would be followed were:

1. The selected data should all be usable, i.e., there would be no occurrences

of obviously erroneous or missing data;

2. If possible, the values of the selected data would be left unchanged, i.e.,

data would not be replaced or modified;

3. The number of data selected would be small, consistent with the fact that

the data should have widespread applicability for researchers having

different needs and using different building energy analysis programs.

DATA SELECTION

The information gathered in this report falls into two broad categories:

(1) general house, occupant, and HVAC information, and (2) specified hourly

measured system performance and weather data. The former use found in

appendices A-C and the latter are found on the data tape.

The general house, occupant, and HVAC information consists of:

1. house information (e.g., location, design, orientation);

2. thermal physical properties of the house envelope (e.g., areas, thermal

conductivities, densities);

3. occupant /occupant-use information (e.g., number of occupants, occupancy

schedule, lighting schedule);

4. HVAC information (e.g., type, maximum capacity, seasonal efficiency).

The data tape information consists of hourly measured values for:

1. ambient dry-bulb temperature;

2. relative humidity;

3. total horizontal insolation;

4. diffuse horizontal insolation;

5. wind speed;

6. wind direction;

7. space air temperature;

8. space relative humidity;

9. energy consumed by HVAC system;

10.

total service energy.

In order to get the above data tape information from the large amount of data

available, a decision had to be made as to how many intervals of data would be

taken from each original data set and, how many days each interval would contain. It was first decided that the most important periods of time (from a residential energy analysis point of view) are the prime heating/cooling

periods and the transition heating/cooling periods (periods when the house

heating/ cooling requirements are small and somewhat sporadic). These periods

are the most important since it is in the former that the majority of the

heating/ cooling energy consumptions occur and it is in the latter that crucial

potential energy savings exist. Therefore, 4 data intervals from each original

group of data were selected:

1. prime heating interval (usually selected from January data);

2. transition heating interval (usually selected from April data);

3. prime cooling interval (usually selected from August data);

4. transition cooling interval (usually selected from October data)

.

Next , it was decided that even though the data for one day is the minimum

necessary and that three day's are probably sufficient for many cases, intervals of 10 consecutive days' duration would be selected. Ten-day intervals

were chosen because:

3
1. it was determined usable data for 10-day intervals could be found in

all the original data for each of the period;

2. 10-day intervals allow the user some amount of discretion in choosing

which day(s) to simulate;

3. 10-day intervals easily allow a computer program using a response

factor-type calculation to use the data as they appear (computer programs using response factors generally need a lead-in period of one to

three days before the effects of the initial temperature and heat flow

conditions disappear).

The 10-day intervals were selected by first looking at plots of the daily HVAC

heating/cooling consumptions versus time for the entire period for which data

were available (see figure 1). A prime heating, a transition heating, a prime

cooling, and a transition cooling period were identified. Next, the data in

these identified periods were analyzed in detail to find candidate intervals

(of 10 consecutive days duration) in which all of the data parameters (e.g.,

dry-bulb temperature, total insolation, space air temperature, etc.) were available (see figure 2). Plots of daily HVAC energy consumption versus daily

average dry-bulb temperature for these intervals were then generated. If an interval showed poor correlation between these parameters an interval having

better correlation was sought (see figures 3 and 4). Finally, plots of the

hourly ambient dry-bulb temperature, HVAC system energy consumption and total

service energy versus time were visually scanned for occurrences of abrupt

changes in adjacent data points (see figure 5). If these abrupt changes could

not easily be explained by corresponding changes in other data parameters, a new candidate interval was selected. In this manner, intervals consisting of

well-behaved usable data were selected from each group of original data.

DATA

3.1 HEAT PUMP DATA

These data were taken from reference 1. The five test dwellings are all

detached single-family homes. They are located in Oakdale, California;

Lancaster, California; Albuquerque, New Mexico; Warren, Arkansas, and White

Plains, New York. Three of the houses are one-story slab-on-grade construction,

one house is a one-story over crawlspac construction, and one house is a twostory over basement and crawlspace construction. The walls range in value from

R-ll to R-23 and the ceilings from R-16 to R-36 . All of the data were taken in

1976.

These data are of particular interest because they are for homes having heat

pumps (which are having widespread use due to their efficiency) and because of

the climatic variation (heating degree days from 1245 to 4848 and cooling

degree days from 1068 to 1525, base 65°F). The heat pump energy and the

resistant heat energy were measured separately.

The data for the houses with heat pumps are found in appendix A and the first

five files on the data tape.

3.2 HOUSTON DATA

These data were taken from reference 2. The test dwelling is a wood-frame

rambler with brick veneer outer covering and constructed over slab-on-grade.

The walls are insulated with 3.5 inch rock wool batts and the ceiling with 4.0

inches of loose rock wool. The test house is located in Houston, Texas, and

the data taken during the summer of 1977. These test data differ from the

other two sets of data examined in five major respects:

1. the house was not occupied (occupant heat generation was simulated by

heat from electric light bulbs);

2. only summer (cooling) data were taken;

3. the hourly sensible cooling load was measured;

4. the hourly space relative humidity was measured (humidity variations

were due to air infiltration);

5. the daily latent load was measured.

Because of point one above, these data were not subject to the perturbations

that can be caused by occupancy action. It is worth mentioning that part of

these data have already been run on the DoE [6], BLAST [7], and NBSLD [8]

computer programs with very good results [9] .

The data pertaining to this house are found in appendix B and file six on the

data tape. Note that this file is only 20 days long since it consists of only

cooling data.

10
3.3 TWIN RIVERS DATA

These data were taken from reference 3, and represent only a very small portion

of the total data available from this source. At one time or another, 27 townhouses were instrumented in Twin Rivers, New Jersey, during the years 1973 to

1977. These data are and probably will be the most comprehensive building

energy data for a townhouse community. The data have undergone extensive

studies and the interested reader is again referred to the above reference.

The heating data for this study were chosen from the very large original data

set by selecting data for the townhouse whose daily winter heating energy had

the best correlation to daily average outdoor dry-bulb temperature. Since the

cooling data for this townhouse appeared to be representative of the other

houses it too was selected.

The data in this section differ from the data in 3.1 and 3.2 in that they

represent measured data for a residential multi-family dwelling rather than a detached single-family dwelling. The data are for a townhouse of conventional

construction, with frame walls and R-7 insulation. The townhouse consists of

two floors (each of about 720 ft^) over a full, unfinished basement.

It should be pointed out that the original data set had neither dew point

temperatures nor relative humidities. In keeping with our stated philosophy of

having the data directly usable, relative humidity values were generated and

put on the data tape. These generated relative humidity values were taken from

National Weather Service daily relative humidity profiles for an average January,

April, August, and October day [10]. These generated values should have little

effect on heating analysis since there was no humidifier in the dwelling. For

cooling analysis, however, these generated relative humidity values will have

a significant effect because of the latent contribution to the cooling requirement. The user is cautioned to keep this point in mind as a possible source

of error when comparing calculated cooling energy consumption to measured

energy consumption (which has a latent energy portion in it).

The general house data for this section are found in appendix C and File 7 on

the data tape.

11
4. DATA TAPE FORMAT

The data are contained in seven files on a single reel of unlabeled nine track

magnetic tape. The data are recorded in ASCII notation at a density of 1600

characters per inch. Each file is followed by one end-of-file (EOF) mark with

the exception of the last file (File 7) which had two EOF's following it.

Table 1 lists some important information regarding the tape files.

Each physical tape record contains all the data for a given hour. Thus, 24

records constitute one day's (24 hours) data. For ease of access, all the

records have the same format. Table 2 gives a description of the record format.

A listing of the first 24 records from File 1 is found in table 3.

Within each file the selected ten-day periods are run sequentially together.

For example, in file one, a ten-day period (240 records) of prime heating is

followed immediately by a ten-day period of moderate heating, which is followed

by a ten-day period of prime cooling, which is then followed by a ten-day period

of prime cooling, which is then followed by a ten-day period of moderate cooling.

This arrangement allows a user to run through all the selected data for a given

house by simply reading the proper file. A prospective user should keep in

mind the following two points:

1 . For those simulation programs that need to stabilize to ambient weather

conditions, the predicted results for the first two or three days of each

10-day heating/cooling period will probably have a certain degree of error

in them.

2. The selected 10-day periods usually do not end on the last day of a month,

therefore, those computer programs that depends on the last day of a month

to key their output will not be activated properly.

5. CONCLUSIONS

The measured data discussed in this report (and encoded onto the accompanying

data tape) provide a tool for the testing and verification of building energy

analysis programs. The data are representative of that found in excessive

experimental efforts to quantify residential energy use. The data are of sufficient detail in measurement of building energy use parameters and of variety in

building type, location, and HVAC system as to have widespread application for

building researchers.

A prospective user of any of these data should not expect to track the data

identically, but should expect to predict major trends in energy use. The

accuracy of the analytical predictions depend on the type of energy analysis

program chosen. One would hope that a rather sophisticated program could predict the energy use results for a several day period within 10 to 15 percent.

Of the three groups of data, the Houston cooling data are probably the best use

in determining how closely a given program predicts the measured results. This

is because the Houston data resulted from an intensive data gathering effort over a relatively short time span for unoccupied houses; thus, data problems

were discovered quickly and the data did not have inherently random influences caused by human actions. However, the heat pump data and the townhouse

data are interesting because they do reflect these influence occupants had on the house energy use and in the final analysis a building energy analysis

program must also produce reasonable results for this real world case.

A data tape containing information for commercial buildings could also be

produced from existing data sources. However, this is a more difficult task

than the one accomplished here and it is suggested the endeavor should not be

undertaken until the usefulness of this tape has been shown.

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

bi bl iography or literature survey, mention it here)

A set of measured residential data has been culled from three larger data sets

for use in the testing and verification of building energy analysis programs.

The data consist of hourly values for heating/cooling system performance and

weather conditions that are sufficient in detail, it is believed, for all

existent computer programs. These dats have been encoded onto a magnetic tape.

In addition, general information has been collected on the houses, occupants/

occupant use, and heating/cooling systems.

12. KEY WORDS (Six to twelve entries; alphabetical order; capitalize only proper names; and separate key words by semicolons)
