PREFACE

This is the first in a series of reports from the Office of the Consumption 

Data System (CDS) presenting data from the Nonresidential Buildings Energy 

Consumption Survey (NBECS),, The NBECS has been designed and developed and 

is now being analyzed by CDS. This is the first time that either the 

public or private sector has developed a method of collecting data on a 

statistical sample of nonresidential buildings across the country. 

Subsequent reports will cover conservation activities, fuel use, distri 

butions of building types, fuel oil capacity, and energy consumption and 

expenditures. Concurrently, this office is designing and testing an 

efficient DOE nonresidential buildings sampling frame and a new question 

naire which will provide additional needed data* These new methods will 

provide an efficient means of collecting consumption and expenditures 

data for individual buildings as well as the entire commercial/ 

nonresidential buildings sector.

This report presents building characteristics data collected from interviews 

conducted between October 1979 and January 1980. The tables present 

data from the final interview file which contains imputations for missing 

data. Included in this report are: a summary of findings, an explanation 

of the relative standard errors, a description of how the survey was 

conducted, a copy of the questionnaire, and a glossary.

Maryland under the direction of Renee Slobasky and Pat Skinner with 

Morris Hansen responsible for statistical design.
INTRODUCTION

This report presents data on the characteristics of nonresidential buildings 

in the 48 contiguous States and the District of Columbia. The information 

was collected through personal interviews conducted with building represen 

tatives between October 1979 and January 1980. A summary of the survey 

design, data collection procedures, and techniques used to convert the sample 

data to national estimates is found in Appendix B (How the Survey Was 

Conducted)* *

The report contains two major sets of tables. The first set (Tables 1A-12C), 

presents estimated counts and percent distributions by building type for 

selected building characteristics. These building characteristics includes 

location; structural features; use and occupancy characteristics; types 

of heating and cooling systems; and types of fuels coming into the building. 

Building type is given separately for nonresidential and commercial 

buildings. Nonresidential buildings have been defined as roofed and walled 

structures which house some kind of commercial and/or industrial activity. 

Buildings which were primarily residential but also showed evidence of 

commercial or industrial activities were within the scope of the survey. 

Commercial buildings exclude those where industrial activities occupy 

more space than any other building activity (see the Glossary for 

definitions of terms). The second set of tables (13A-23C) presents the 

same building characteristics for all nonresidential buildings by square 

footage and year of construction.

Each set of variables is presented in three types of tables. In the 

first type of table, each cell contains an estimated count of buildings 

in thousands. The second table expresses the buildings in each cell as 

a percent of a row total, that is, each row sums to 100 percent. In the 

third table type, the buildings in each cell represent a percent of a 

column total (each column sums to 100 percent). Thus in Table 1A, there 

are 192,000 office buildings in the North Central region. In Table IB, 

these buildings represent 32 percent of all office buildings. In 

Table 1C, these buildings represent 15 percent of all buildings in the 

North Central region.

^Because the data came from a sample of nonresidential buildings rather 

than the entire population, the estimates in this report are subject to 

sampling as well as nonsampling errors, and biases. These issues are 

discussed in Appendix A (Limitations of the Data). Estimates of the sampling 

error component have been produced for statistics in this report. They are 

given in Appendix A for the detailed tables and in parentheses after specific 

estimates quoted in the text. Sampling errors can be used to test statistical 

inferences made in the text. Testing procedures are also discussed in 

Appendix A.
Summary of Findings

At the time the Nonresidential Buildings Energy Consumption Survey was 

conducted, there were an estimated 4,238,000 (+ 398,OOO) 2 nonresidential 

buildings in the United States. Of these, 3,995,000 (+ 384,000), or 

approximately 94 percent,, (+ 1.8) were classified as commercial buildings; 

the remainder were classified as industrial. The South and North Central 

regions had the largest numbers of nonresidential buildings, 1,566,000 

(+ 323,000) and 1,326,000 (_+ 281,000), respectively, with the Northeast 

and West regions having only about half that many.

A large proportion of nonresidential buildings are relatively small; 

57 percent (+ 3.5) have a total enclosed area of no more than 5,000 

square feet, which is about the size of a regulation basketball court. 

The proportion of buildings with only one floor is 58 percent (+ 3.5). 

Only 7 percent (+ 1.3) of all nonresidential buildings have more 

than 3 floors. In 72 percent (+ 3.2) of all buildings, the average 

number of people working in the building is less than 10. The present 

building stock is also relatively modern; 2,649,000 buildings (+ 286,000), 

or 63 percent (+ 3.4) of the total were built after World War II, and 

19 percent (+ 2.5) were built since 1970. Single establishment buildings 

account for 83 percent (+ 2,,8) of the nonresidential buildings stock and 

approximately two-thirds of all nonresidential buildings are occupied 

by the owner or his agent.

The great majority of all nonresidential buildings are heated (89 percent, 

+ 1.7) while a smaller proportion are cooled (64 percent + 3.4). The 

building population is divided quite evenly between use of self-contained 

heating units (1,752,000 buildings, + 217,000) and central systems (1,920,000 

buildings + 230,000). There are also no statistically significant differ 

ences among the number of buildings that are cooled by window units, 

package units, and central systems.

Virtually all nonresidential buildings use electricity as an energy source.. 

The second most often-used fuel is natural gas, which is supplied to 

2,413,000 buildings (+ 270,000), or 57 percent (+ 3.5) of the total stock. 

Fuel oil/kerosene is third, used by 872,000 buildings (+ 134,000) or 

21 percent (+ 2.6) of the building stock. Seven percent (+ 1.3) of the 

buildings are supplied with LPG and 3 percent (+ .8) use wood. Coal, steam, 

and other fuels are used far less often.

+ values given in parentheses after a statistic quoted in the text 

represent two standard errors of the statistic. Adding and subtracting the 

value in parentheses from the statistic will produce an approximate 

95 percent confidence interval.
Building Type

Initially, a building was assigned to a particular building type if a single 

activity occupied 75 percent or more of the space In that building.-^ 

Following this procedure, approximately 16 percent of the buildings were 

classified as "mixed-use". For this report, "mixed-use" buildings have been 

categorized according to the predominant building activity. Table A shows 

how the "mixed-use" buildings were reassigned (data do not sum to total due 

to rounding).

Table A. Mixed-Use Buildings

Percent of Total 

Predominant Building Activity Buildings

Food sales and service 1.0

Office 2.7

Residential 5,9

Retail sales and personal services 1.5

Warehouse and storage 1.2

Other 2.1

Total 14.3

For the building classification scheme used in this report, the most fre 

quently occurring building category is "retail sales and personal services" 

which accounts for an estimated 17 percent (+ 2.3) of all nonresidential 

buildings. The next largest category Is "office," which accounts for 

14 percent (+ 2.0) of the building stock. However, there is no one category 

that stands out significantly from the others. An estimated 146,000 

buildings (+ 39,000), or 3 percent (+ 0.8) of the total stock, were vacant 

at the time of the survey. The distribution of building types does not 

vary greatly by region.

There are some notable differences in the size distribution for the various 

building types. "Education" and "industrial" buildings are larger than 

average in terms of square footage. Only 27 percent (+ 8.1) of "education" 

buildings and 33 percent (+ 7.7) of "industrial" buildings are no larger 

than 5,000 square feet, whereas 42 percent (+ 9.3) and 26 percent 

(+ 7.0) of them, respectively, are over 25,000 square feet. However, 

neither of these building types are above average in height. "Automotive 

sales and service" buildings and "food sales" buildings tend to be smaller 

than other building types. Seventy-two percent (+ 6.5) of "automotive 

sales and services" buildings and 76 percent (+ 7.0) of "food sales" 

buildings are less than 5,000 square feet, while only 2 percent (+ 1.3) 

of each of these building types are over 25,000 square feet. "Automotive 

sales and service" buildings are generally not multi-storied; 81 percent 

(+ 5.6) have only 1 floor, and no sample "automotive sales and service" 

buildings taller than 3 stories were found.

the definition for building type in the Glossary for the detailed 

building classification scheme.
While the total building stock was evenly divided between self-contained 

heating units and central systems, the split was not as consistent for 

certain building types. Only 30 percent (+ 6.0) of assembly buildings and 

30 percent (+ 8.3) of "education" buildings used self-contained heating units, 

while approximately two-thirds of these buildings used central systems. On 

the other hand, 55 percent (+ 7.2) of "automotive sales and service" buildings 

used self-contained heating units, while only 33 percent (+ 6.5) used 

central systems. Of the occupied building types, only the "warehouse and 

storage" category had a large proportion of unheated buildings: 43 percent 

(+ 6.9).

The presence of air conditioning equipment varied substantially by building 

type. Overall, 64 percent Q+ 3.4) of nonresidential buildings were air 

conditioned. The percentage of air conditioning among occupied building 

types ranged from 35 percent (+_ 6.7) for "automotive sales and service" 

buildings to 90 percent (+ 4.1) for office buildings,

Electricity was supplied to more buildings than any other energy source. 

The only building type (other than "vacant" buildings) for which electricity 

consumption was not virtually universal was "warehouse and storage" of 

which 85 percent (+ 6.3) were supplied with electricity,

The distribution of the average number of persons working in the building 

varied greatly by building type. The proportion of buildings with an 

average of fewer than 10 workers ranged from 36 percent (H- 9.0) for "education" 

buildings to 88 percent (4- 4.3) for "automotive sales and service" buildings. 

"Education", "industrial",, and "health care" buildings tended to have more 

workers than the average building: 16 percent (+ 6.1), 20 percent (+ 6.1) 

and 27 percent (+ 12.0), respectively, of these building types had 50 or more 

workers.

One measure of intensity or availability for use of a building is the number 

of hours it is open for operation during a typical week* As might be 

expected, lodging buildings were open for very long hour:::. An estimated 

74 percent (+ 10.5) of all lodging buildings were open more than 84 hours 

per week. Interestingly „ another 14 percent (_+ 6.6) of these buildings 

were open less than 40 hours per week. This pattern contrasts dramatically 

with that of office buildings, of which 75 percent (+ 5.7) were open from 

40-60 hours per week. "Food sales" buildings are also open for long hours. An 

estimated 76 percent (+ 7.0) were open longer than 60 hours per week. Of 

the occupied building types, "assembly" buildings were most likely to be open 

for short periods; 63 percent (+ 7.0) were open less than 40 hours per week.
Square Footage

One of the descriptive variables that should be correlated with energy 

consumption in nonresidential buildings is square footage. As mentioned 

earlier, an estimated 57 percent (+ 3=5) of all nonresidential buildings 

have less than 5 S 000 square feet of space* Only 10 percent Of 1.7) have 

more than 25,000 square feet of space. The distribution of buildings by 

size category remains fairly uniform by region.

As might be expected, square footage is positively associated with the 

number of floors. The percentage of buildings with only 1 floor decreases 

as square footage increases, from 88 percent (+ 3.9) of buildings less 

than 1,000 square feet to 15 percent Of 7.5) of buildings greater than 

100,000 square feet- Conversely, the percentage of buildings with more 

than 3 floors increases with square footage from 1 percent (+ 2.0) of 

buildings with less than 1,000 square feet to 46 percent (+ 12.1) of 

buildings over 100,000 square feet.

There are no obvious relationships between type of heating and/or air 

conditioning equipment and square footage, except that the use of window 

units decreases somewhat as building size increases, while the use of 

central units increases. However, smaller buildings are much more likely 

than large buildings to have no heating and/or cooling equipment at all. 

Of buildings having no more than 1,000 square feet, 52 percent (+_ 6«2) are 

not air conditioned and 25 percent (jf 4*8) are not heated, whereas only 

13 percent {+ 6.9) of buildings over 100,000 square feet are not cooled and 

2 percent (+ 4,0) are not heated.

The percent of exterior glass is inversely related to the size of the 

building. Seventy-one percent (+ 3.8) of the buildings with 5 S 000 square 

feet or less have less than one-fourth of their surface area covered by 

glass, while only 44 percent Of 12 6 0) of the buildings over 100,000 square 

feet have less than one-fourth covered by glass.

Another variable that correlates well with square footage, as would be 

expected, is the number of people working in the building* The proportion 

of buildings with an average of fewer than 10 workers drops sharply from 

97 percent (+ 2.5) for buildings of 1,000 square feet or less to 8 percent 

Of 8.0) for buildings over 100,000 square feet. Conversely, virtually no 

buildings under 10,000 square feet have an average working staff of 100 or 

more, but 59 percent Of 12.0) of buildings over 100,000 square feet average 

at least 100 workers.

Finally, larger buildings are more likely to be open for very long hours, and 

less likely to be open for very short hours, than are smaller buildings. The 

proportion of buildings open less than 40 hours during a typical week 

decreases steadily from 36 percent Of 5*6) of buildings with 1,000 square feet 

or less to 4 percent (+ 6.0) of buildings with more than 100,000 square 

feet. Conversely, the proportion of buildings open longer than 84 hours 

increases from 15 percent (4- 3.8) of buildings with 1,000 square feet or 

less to 42 percent (+ 11.7) of buildings with more than 100.000 square feet.
Year Constructed

"Year constructed" has been sub-divided into seven categories. The end 

points of these categories reflect times of significant change in con 

struction methods and building standards. Statistics for the more recent 

categories represent values for the large majority of buildings constructed 

during these periods, while estimates for the earlier time periods represent 

values for surviving buildings, rather than for all construction that took 

place. An estimated 329,000 buildings (+ 68,000), or 8 percent (+ 1.5) 

of the total building stock at the time of the survey,, were constructed 

before 1900. Buildings; constructed since 1970 account for 19 percent 

(+ 2.4) of the building stock. The largest regional differences occur 

in the oldest categories. An estimated 32 percent (4- 5.3) of buildings 

in the Northeast region and 23 percent (HK 3.8) in the North Central 

region were constructed in 1920 or before, compared with 10 percent 

(+ 2.3) and 12 percent (-1- 3.4) of the stock in the South and West 

regions, respectively.

There is a sharp contrast, in the number of floors 'between buildings 

built up to 1945 and those built afterward. A large proportion of the 

older buildings have 3 or more floors, while 71 percent (+ 3.7) of the 

newer buildings have only 1 floor.

A smaller proportion of older buildings than newer buildings have selfcontained forced-air heating units, and a corresponding larger proportion 

have radiant central systems. Similarly, older buildings are more likely 

to have window units, and less likely to have package units and central 

units than newer buildings. In the case of air conditioning, the dividing 

line between "older" and "newer" buildings appears to be 1960 rather than 1945

It is interesting to note that there is no obvious relationship between the 

age of a building and the percentage of exterior glass. In fact, older 

buildings (those built in 1920 or earlier) appear to have slightly more 

exterior glass than buildings built later, although this difference is not 

statistically significant. One explanation may be that a disproportionate 

share of large older buildings are still standing and these buildings tend 

to have a larger proportion of glass than small buildings.

Electricity use is equally predominant in buildings of all ages, but natural 

gas and fuel oil/kerosene use is relatively more frequent in older buildings« 

The proportion of buildings that use natural gas decreases from 73 percent 

(4-5.4) of buildings built before 1920 to 36 percent (+ 5.9) of buildings 

built after 1973, while the proportion using fuel oil/kerosene decreases 

from 31 percent (+6.7) of buildings built before 1.900 to 12 percent 

(+ 3.5) of buildings built after 1973.

Older buildings are more likely to have a smaller average number of workers

PROGRAM DEVELOPMENT, fcNERGY INFORMATION ADMINISTRATION, U.S. DEPARTMENT OF' ENERGY, THE 1979 NONRESIDENTIAL BUILDINGS ENERGY 

CONSUMPTION SURVEY.
A. LIMITATIONS OF THE DATA

Data from the Nonresidential Buildings Energy Consumption Survey are subject 

to many sources of sampling error, nonsampling error, and bias. Sampling error 

is a measure of the variability In the data because a subset of buildings was 

surveyed rather than the entire population. Because the survey used probabi 

lity sampling techniques, it is possible to estimate sampling errors of the 

survey estimates and use these sampling errors as a guide in making inferences 

from the sample observations to the total population. (These topics are 

discussed in later sections of the Appendix.) Nonsampling error and bias are 

measures of variability In survey data due to the conduct of the survey. They 

can include respondent bias and response variance, interviewer error, coding 

and/or punching error, and nonresponse bias. Estimates of variance and bias 

due to these sources of error are not available for this survey. The wording 

and format of the survey questionnaires, the procedures used to select and 

train interviewers, and the quality control built into the data collection, 

data receipt, and data processing operations were all designed to minimize 

these sources of error (for discussion of these procedures, see Appendix B— 

How the Survey Was Conducted).

One way to judge the validity of survey estimates is to compare them with 

similar types of estimates from other sources. However, since no national 

counts of the nonresidential building stock exist, and since no national 

probability sample surveys of this population are known to have been previ 

ously undertaken, such comparisons cannot be made. The lack of prior informa 

tion also made It impossible to use techniques such as ratio estimation or 

post-stratification in the estimator. These techniques, which can help to 

increase the precision of survey estimates, could not be used because there 

were no benchmark values of buildings, or variables correlated with buildings, 

that were available to make such adjustments.

Computation of Sampling Errors

The complex multi-stage, multi-frame design of the survey makes It virtually 

impossible to construct an exact algebraic variance estimator. The method 

used to produce variances for this survey is balanced half-sample replication 

(see References 1 and 2). In order to apply the half-sample technique to this 

survey, the 79 sample primary sampling units (PSU's) were grouped into 37 

strata* Eighteen of the strata were self-representing; that is, they consisted 

of large metropolitan areas that came into the sample with certainty. In 

these strata, segments were divided into two replication groups. Each of the 

remaining 19 strata consisted of two or more sample PSU's belonging to the 

same Census region. The two replication groups in these strata consisted of 

one .or more PSU's each.

Variance estimates for selected survey statistics were created by computing 

40 half-sample estimates for each statistic. Each half-sample estimate was 

formed by selecting one of the two replication groups from each stratum using

89
an orthogonal matrix technique adapted from an article by Plackett and Burrtmn 

(Reference 3). Then the sampling weights were adjusted so that the halfsample estimates would be essentially unbiased estimates of the corresponding 

population parameter, as was the estimate based on the entire national sample.

The variance estimate for the survey estimate X' of characteristic X is giver? 

by:

s 2 «= _I £ (X" - X') 2 

X' 40 i=l :L

where X' is the i half-sample estimate of X.

Summary and Display of Sampling Errors

Instead of displaying a computed error estimate for every statistic in this 

report, the variances are summarized in the error curves shown in Figures 1 

and 2.

There are two reasons why the summary curves are used:

(1) Showing an error estimate for every statistic in the detailed tables 

would mean producing an error table for each detailed table, thus 

doubling the size of the report.

(2) Because the half-sample variance estimates are themselves subject to 

sampling error, certain variance estimates would be misleading 

simply because they are outliers.

The error curves were constructed from variance estimates computed

for selected statistics in the report by a least squares fit of the log-linear

model

log [RSE (X')] =A+B [log (X')]

where A and B are the parameters whose least squares estimates determine the 

shape of the curve, and RSE (X'), the relative standard error of X', is given

by

s RSE (X') = _ ' X'

X' *

Thus the standard error of X', the error form used in the text of this report „ 

is given by

S , == RSE (X") • X'. (A)

91
Separate curves are shown for estimates within a region and estimates over all 

regions since the clustered design of the sample tends to make regional esti 

mates more variable than national estimates of the same magnitude.

Use of Error Curves

Standard error estimates for any aggregate statistic (number of buildings) in 

this report can be produced directly from the error curves in Figures 1 and 2,, 

For example, Table 8A shows that an estimated 356,000 office buildings are 

supplied with natural gas. By reading up from the 356,000 value on the' hori 

zontal axis of Figure 1 and then to the left to the vertical axis, the RSE 

is 10 percent, or the standard error is (.10) (356,000) = 35,600. In Table 1A 

there are an estimated 139,000 food sales buildings in the South region. By 

reading up from the 139,000 value on the horizontal axis of Figure 2 and then 

to the left to the vertical axis, the RSE is 16 percent, or the standard error 

is (.16) (139,000) = 22,240.

Standard error estimates for percentage statistics can be produced indirectly 

from the error curves using the approximation

RSE = /RSE2 (X') - RSE 2 (Y') (B)

For example, Table 11B shows that 26 percent of all "automotive sales and 

service" buildings are open from 61 to 84 hours in a typical week. This 26 

percent statistic is based upon a numerator of 106,000 buildings and a denom 

inator of 401,000 buildings, from Table 11A. Using the curve in Figure 1 in 

the manner previously described, the RSE of 106,000 is 15 percent while the RSE 

of 401,000 is 10 percent. Therefore, the estimated RSE of the 26 percent 

statistic is

RSE (.26) =>/(.15) 2 - (.10) 2 * 0.11 

and the standard error is (.11) (26) = 2.9 percent.

Using Standard Errors to Test Statistical. Hypotheses

The analytical statements in this report can be divided into three types. Ths 

first type is the expository statement, which presents a statistic for its own 

sake, without reference or comparison to any other statistic. An example of 

such a statement is found in the first sentence under "Summary of Findings": 

" ... there were an estimated 4,238,000 (+ 398,000) nonresidential buildings in 

the United States". No statistical tests of hypothesis are needed or were 

performed for such statements; twice the standard error is given in parenthesas 

after the estimate. This value serves as a measure of the level of variability 

in the statistic, and allows the reader to compute an approximate 95 percent 

confidence interval for the estimate by adding and subtracting the value in 

parentheses.

92
The second type of statement is the descriptive statement, which is intended 

as a summary statement of a data relationship or relationships that exist in a 

table. An example of this type of statement is found in the first sentence of 

the last paragraph of the text section entitled, "Square Footage"; "Finally, 

larger buildings are more likely to be open for very long hours, and less 

likely to be open for very short hours, than are smaller buildings". Such 

statements are meant to give general impressions and are not subject to 

statistical justification.

The third, and most commonly occurring type of statement, is the stated or 

implied comparision between two or more statistics. Such comparisons are 

meant to point out specific similarities and differences between population 

subgroups, sometimes in support of the summary statements discussed above. 

Since these statements imply specific relationships among population subgroups 

based on sample data, they are inferential, and subject to statistical 

testing. Examples of such comparisons are

(1) Sentence 2 in paragraph 4 under "Summary of Findings": "The second 

most often-used fuel is natural gas, which is supplied to 2,413,000 

buildings (+ 270,000), or 57 percent (+ 3.5) of the total building 

stock".

(2) The last sentence of paragraph 4 under "Year Constructed": "The 

proportion of buildings that use natural gas decreases from 73 

percent (+_ 5.4) of buildings built before 1920 to 36 percent 

(jt 5»9) of buildings built after 1973, while the proportion using 

fuel oil/kerosene decreased from 31 percent (+_ 6.7) of buildings 

built before 1900 to 12 percent (+ 3.5) of buildings built after 

1973.

Example 1 implies that the number of buildings supplied with natural gas was 

compared to the number supplied with all other fuels. The number supplied 

with natural gas was found to be smaller than the number supplied with electri 

city and larger than the number supplied with each other fuel. Example 2 

specifically states the two comparisons of interest.

The test used to check this kind of statement is the standard normal deviate 

test. In order to test the significance of the difference between estimates 

X' and Y', X' and Y' are assumed to be normally distributed by appeal to the 

Central Limit Theorem. Then the test statistic

X" - Y" (C) 

Z , , = / 2 "2~ x » Y y sj, + s*.

93
is computed, with Z having approximately a standard normal distribution. The 

null hypothesis, that there is no difference between X* and Y', is rejected if 

|Zx' Y'I 1 s greater than some critical value G. In this report, G is set so 

that the level of significance of the test (the probability of incorrectly 

detecting a significant difference) is .05. Ordinarily, this level of signifi 

cance corresponds to a critical value of 1.96, and when a comparison is the 

only possible one of its type, 1.96 is the correct value. However, most of 

the statements in this report involve comparisons that were selected from a 

larger set of C possible comparisons, each of which had an opportunity to be 

tested and falsely yield a significant difference. In order to attain a true 

level of significance no greater than .05 for a particular test from such a 

set, the critical value G was adjusted so that the probability of falsely 

detecting any significant difference was .05/C. The rationale for this 

adjustment is based on the Bonferroni inequality, and. Is discussed elsewhere 

(see References 4 and 5)»

The normal test of an hypothesis with adjusted critical value can be applied 

to the examples as follows;

(1) The statement that natural gas is the second -most often—used fuel 

implies significant differences in comparisons between it and all 

other fuel types shown in Table 8A.

The following data can be collected from Figure 1 and Table 8A:

The number of possible comparisons among the 8 fuel categories in 

Table 22 is the combinatorial (jb = 28, so the critical value for 

all tests is the normal two-tailed ' 12% ~ *0018 critical value which, 

from the standard normal tables, is 3.12.

The test statistic for the comparison between electricity and natural 

gas is

4.109 - 2.413 1696 • " ?

V(193)2 + (135)2 " 235 ' 529

The Z value exceeds the critical value of 3.12, so the difference is 

significant. Similarly, the comparisons between natural gas and the 

remaining fuel sources can be shown to have Z values exceeding 3.12. 

Therefore, the statement is justified.

(2) Example 2 comes from Table 19B. The number of possible comparisons 

between specific ranges of year of construction is the combinatorial 

(7) = 21 for each fuel type. Since comparisons could be made for 

each of the 8 fuels, the total number of possible comparisons underlying 

this statement is 8 x 21 = 168. Thus the critical value for all compari 

sons is the two-tailed * 05 /i68 == -0003 critical value, which is 3.61.

The estimates and error values in Example 2 can be used to perform the 

required tests. The error values must be divided by 2 to apply the 

tests, because they represent two standard errors. The test statistics 

for the two differences implied by the statement as being significant are

7 73-36 = 37 =0 . 7 , 

\/(2.7) 2 4- (2.95) 2 4

v 31 - 12 19 _ n , Z2 = ' = ——— = 5.03

\/(3.35) 2 4- (1.75) 2 3.78

Since both Z values are greater than 3.61, both differences are significant 

and the statement is justified.

B. HOW THE SURVEY WAS CONDUCTED

Introduction

The Nonresidential Buildings Energy Consumption Survey was designed by 

the Energy Information Administration (EIA) to provide information related 

to energy consumption in nonresidential buildings, primarily those in 

the commercial sector. This survey, along with analogous studies for 

the residential and industrial sectors, will enable the analysis of 

comprehensive consumption patterns for the United States.

Information on energy use in the commercial sector was collected at the 

building level. A representative sample of buildings was selected in 

the 48 contiguous States plus the District of Columbia. The data on 

actual energy consumption is currently being collected from fuel records 

maintained by the buildings' fuel suppliers. Energy consumption data 

will also be obtained for establishments within surveyed buildings when 

they are separately metered s but their totals will be aggregated to the 

building total. The results of this phase of the survey will be available 

in winter 1981.

Sample Design

The building sample is a multi-stage, representative area probability 

sample consisting of 79 primary sampling units (PSU's). The approxi 

mately 3,100 counties and independent cities of the contiguous United 

States were grouped into about 1,900 PSU's by the Census Bureau for its 

Current Population Survey. These PSU's, with some modifications, were 

used to construct the first-stage area-sampling frame. All PSU's having 

a 1970 population of over 1.85 million were designated as self-representing; 

that is, they were chosen with certainty. Each nonself-representing PSU 

was placed in a stratum on the basis of metropolitan status, region, 

various size measures, and socio-economic status. The 79 sample PSU's 

were selected with probabilities proportionate to their 1970 population.

The sample PSU's were then divided into secondary sampling units corres 

ponding to zip codes or groups of zip codes. Procedures were designed to 

handle zip codes that overlapped county boundaries and/or zip codes that 

were assigned to large commercial establishments or Government agencies.

Each zip code was assigned a. measure of size based jointly on summary 

data from the 1975 County Business Patterns (CBP) and on proprietary 

commercial data related to office machines. The CBP data were counts 

of establishments by 2-digit Standard Industrial Classification (SIC)

97
code and employment size according to zip code. The measure of size 

assigned to a zip code was an integer equal to the number of segments 

into which a zip code would be divided if drawn into the sample. The 

sizes were assigned in such a way that segments would contain an average 

of 120 establishments based on the CBP tabulations,, After assignments 

of the measures of size were made, a sample of about five zip code 

groups was selected in each PSU with probabilities proportionate to the 

number of segments in each zip code group, giving a total second-stage 

sample of about 400 zip code groups.

The sample of third-stage units consisted of approximately 400 segments, 

one selected from each of the sampled zip code areas. The selection of 

the segments was done in such a way that one percent of all segments in 

the contiguous United States was included in the sample, each having an 

equal chance of being selected. In zip code groups with measures of size 

of 6 or more, the segments were compact areas. It was feasible to define 

area segments within these selected zip code groups on the basis of prior 

field work done in the selected zip codes. In the zip code groups with 

smaller measures of size, the segments were, in effect, selected from 

listings made for the complete zip code group.

Nonresidential buildings were selected from the area segments at the 

fourth-stage of sampling. With a few exceptions, a nonresidential build 

ing was defined as a structure that (1) was totally enclosed by walls 

that extend from the foundation to the roof line, and (2) housed some 

type of nonresidential activity. The first step in the selection process 

was to do a field canvass to identify and list the addresses of all 

in-scope buildings within each sampled segment. As part of the listing 

procedure, the lister made rough estimates based on observation of 

descriptive information related to energy usage, including square 

footage and general use. This information was used to categorize 

buildings for subsampling. About 75,000 buildings were listed (this 

includes the extra listings in zip code groups with measures of less 

than 6) from which approximately 5,800 buildings were selected for 

interview. Subsampling fractions from the one percent sample of seg 

ments varied from 1 in 1 for buildings having measures of size of 

50,000 or more square feet as assigned by the lister, to 1 in 20 for 

small buildings (less than 10,000 square feet) of certain types.

Another part of the sampling procedure entailed the location of "large" 

buildings within the sampled PSU's and placing them on a Special Building 

List. "Large" buildings were defined as those with 250,000 or more 

square feet of enclosed floor space in PSU's that are Standard Metropolitan 

Statistical Areas (SMSA). In the remaining one-third of the PSU's, build 

ings of 100,000 square feet or more were listed. The list of large 

buildings was compiled through inquiries with chambers of commerce and 

other local sources* Some of the large buildings listed were clusters 

of buildings such as a university campus. About 3,200 buildings (or 

building clusters) were included on the Special Building List and approxi 

mately 1,200 of them were included in the sample«, In those cases where

98
the selected unit consisted of a cluster of buildings, the individual 

buildings were listed and subsampled at rates designed to yield the 

desired overall selection probabilities. Large buildings sampled from 

the area sample list were checked against the Special Building List to 

identify duplicates and assign them appropriate selection probabilities.

A total of 547 sampled buildings were ineligible for interview. Build 

ings were designated as being ineligible for interview for a number of 

reasons including: (1) duplication; (2) incorrect or multiple listings; 

(3) sampled structure failed to meet the building definition; and (4) 

the sampled structure was demolished after the list was prepared. Dupli 

cation resulted from duplicate sample selections from the area sample and 

the sample selections from the list of large buildings.

Buildings were listed incorrectly or as multiple listings for several 

reasons. First, the area-sampling technique required that most buildings 

be listed by observation. Therefore, it was not always possible to 

determine the exact scope of a building until the interviewing phase, 

when contact was made with a building owner/manager. Secondly, since 

the list of large buildings was obtained through telephone contacts, 

what was reported over the telephone to be one building frequently turned 

out to be a group of buildings. Buildings that did not meet the study 

definition (e.g., totally residential buildings) were also considered 

out of scope.

Weights were calculated for each sample building to: (1) reflect the 

reciprocals of the probabilities of selection, and (2) adjust for dif 

ferences in the interview completion rate for different classes of 

buildings. The overall response rate in the survey was 92 percent, but 

this varied somewhat for various types of sizes of buildings. The weights 

used in this report may be subject to minor revisions.

Data Collection

The sample consisted of a total of 7,323 buildings. Of these, 6,776 were 

eligible to be interviewed. Westat, Inc., of Rockville, Maryland con 

ducted the interviews. Extensive follow-up efforts were used in field 

data collection, and as a result, interviews were initially completed for 

91 percent of the eligible buildings. Of those interviewed, 88 percent 

signed waivers authorizing utility companies to release their buildings' 

consumption records (see Table 1).

Since the field response was so high, only limited additional follow-up 

procedures were initiated. In January 1980, an overall refusal-conver 

sion effort was undertaken. An attempt was made to conduct telephone 

interviews with building owners or managers who had originally refused 

to be interviewed in person. Calls were made to 197 buildings, and of 

these, 83 interviews were completed. As a result of this effort, 

42 percent of the refusals were converted, and the overall response 

rate was raised by 1 percentage point, to 92 percent.

99
During Decmeber 1979, 727 letters were sent to respondents who had 

completed the interview but did not sign an authorization form to ask 

them to reconsider their decision. From the waiver-conversion effort, 

an additional 122 signed waivers were received, 46 refused, and 599 failed 

to reply. This effort resulted in an overall conversion rate of 17 per 

cent and boosted the waiver response rate by 1 percentage point, to 

89 percent.

In addition to these supplemental follow-up efforts,, some additional 

follow-up was done for a few selected data items that, were missing or 

inconsistent in completed questionnaires. Certain items in the building 

questionnaire, such as size, building activity, and the names and addresses 

of fuel suppliers, were designated as being crucial. If any of the crucial 

items were missing, a telephone call was made to the respondent to try to 

obtain this information as well as any other missing data.

Initial contacts with the building owners and managers were made through 

a letter signed by the EIA Administrator. The letter introduced the data 

collection contractor, stressed the importance of cooperation, and assured 

the confidentiality of responses.

The building interviews were conducted between October 1979 and January 

1980. Respondents were asked about the building as a whole, rather than 

individual establishments located within the building,. Professionals in 

the areas of architecture, building operations, engineering, statistics, 

and survey research were consulted during the development of the inter 

view questionnaire« The interviews averaged 50 minutes and covered: 

structural and operational building features; types of heating, cooling, 

and ventilation systems; fuel used in these systems and patterns of 

usage; and a description of the activities found in the building. At the 

conclusion of the interview, respondents were asked to sign waivers 

authorizing Westat, Inc., to obtain fuel consumption records from the 

buildings' fuel suppliers.

Nearly 90 percent of the respondents signed waivers to permit fuel 

suppliers to give Westat, Inc., monthly records of their fuel purchases 

for the past 14 months. Information was requested on the amount sold, 

the price of the fuel,, and the billing dates. The suppliers of elec 

tricity and natural gas were contacted by mail beginning in August 1979. 

Two letters were sent to each company. The first, signed by the EIA 

Administrator, explained the legal authority and need for the data col 

lection. The second letter introduced Westat, Inc.,, the data collection 

contractor, and discussed the data collection procedures and the kind 

of information that would be requested. Follow-up telephone calls were 

initiated in October 1979 to insure the receipt of the letters and to 

establish a personal contact with the appropriate utility company 

representative.

After the building interviews were completed and the signed waivers were 

received, approximately 230 electric and natural gas companies and about 

1,300 fuel oil and other energy suppliers were identified for participation.

100
At the end of February 1980, each supplier was sent a packet containing 

instructions and explanations, signed waivers, and data-retrieval forms. 

Follow-up telephone calls were made to the suppliers of electricity and 

natural gas in March 1980 to make sure the utility companies received 

the forms, to answer any of their questions, and to obtain an estimated 

completion date. A letter was then sent to confirm the completion date. 

If the data were not received within a week of the completion date, a 

second telephone call was made to deal with any problems that might have 

arisen and to arrange a second date.

Some buildings had many tenants who were metered and billed separately. 

Interviewers were instructed to obtain lists of tenants in buildings 

where establishments were separately metered. If there were three or 

fewer establishments within a building, the interviewer attempted to 

get a signed waiver for each establishment. In buildings with four or 

more establishments, the building owner or manager was asked to sign a 

waiver releasing the aggregate utility records for the occupants of the 

building.

Companies were asked to supply limited consumption data for those build 

ings where an interview was completed but a signed waiver was not obtained• 

While energy suppliers will not provide individual building data without 

a waiver, some will provide aggregate data for groups of nonrespondent 

buildings. This information will be used to analyze the potential bias 

introduced by nonresponse and to improve the accuracy of consumption 

estimates in the commercial sector. The results of the utility survey 

should be available in late 1981.

Adjusting for Nonresponse

The amount of data collected from this survey was reduced by two types of 

nonresponse: unit nonresponse (e.g., noninterview) and nonresponse to 

particular items in an otherwise completed interview. As mentioned 

in the section, "Sample Design", unit nonresponse was handled by 

adjusting the sampling weights of responding buildings. Item nonresponse 

for selected building characteristics was treated by imputing data from 

responding cases, using a separate hot deck procedure for each item. The 

only data element for which a hot deck procedure was not used was square 

footage. For this variable, the lister's guess was used, unless that 

guess was less than 10,000 or greater than 100,000 square feet. When the 

lister's square footage estimate was in either of these categories, an 

average unweighted square foot per floor was computed for all responding 

buildings of the same type in the same size class. This value was then 

multiplied by the number of floors in the building of interest to produce 

an estimate of square footage for the building. Most of the imputed 

building characteristics items had less than two percent nonresponse; two 

of them (year constructed and square footage) had about three percent 

nonresponse, and one item (hours of operation) had about seven percent 

nonresponse.

101
Field Procedures

Once the sampled zip code groups and segments had been selected, the 

initial field step was to prepare a listing of building addresses 

located within the sampled segments (see Sample Design). The sample 

consisted of approximately 400 segments which were listed by a team of 

85 listers. Supervisors attended a 3-day training session during the 

first week of June 1979. During this session a combination of slides, 

exercises, lectures, and an actual listing were used as training devices. 

Supervisors were also given an annotated manual which described the ses 

sion. This manual was used as a guidebook to supervisors in order to 

conduct identical training sessions for the listers,

Prior to their training, each lister received a copy of a Listing Manual 

and a home study package with assignments to be turned in before training 

began. The supervisors trained 85 listers in 2-day sessions conducted, in 

9 cities. As soon as possible after the listing procedure began, the su 

pervisors relisted at. least one segment for each lister. This verification 

provided immediate feedback for the lister and corrected any misunder 

standings. The check also served to identify any definitional problems 

or procedural weaknesses.

Once all the segments had been listed, the field supervisors relisted a 

subsample of 53, not including the segments that, had already been checked* 

The relisting showed that less than one percent of the buildings had been 

missed. Buildings were usually missed because of questions concerning 

segment boundaries.

Training for the interview phase began with a 3-day session for super 

visors and their assistants in September 1979. Approximately 170 inter 

viewers were trained in 3-day sessions held during October and November 

1979. Westat, Inc., conducted the training of both the supervisors and 

the interviewers utilizing a variety of techniques,. The training materials 

used included: an annotated manual, interactive lectures, role-playing 

exercises, audio-visual presentations of the interview techniques, and 

slides relating specific building types to the questionnaire. The super 

visors and their assistants functioned as small-group leaders during the 

interview training.

The completed questionnaires were initially screened by the field 

supervisors. They were reviewed for completeness, correct identifying 

information, and ambiguities requiring clarification. The supervisors 

mailed the completed questionnaires to Westat, Inc., where they were 

subjected to a similar check. Also at this time, certain data were 

categorized and some of the more complex data items such as open-ended 

questions, were put into special processing. After the manual editing, 

the questionnaires were coded, keypunched, verified, and computerized. 

A machine edit check was made for reasonable values, proper skip patterns, 

and logical inconsistencies.

102
Weather Data

Two types of weather data will be used in conjunction with the building 

interview and consumption data. The first type is the 54-year annual 

average heating degree days (HDD) and cooling degree days (CDD) for the 

National Oceanic and Atmospheric Administration (NOAA) weather division 

in which the building is located. These data will be used in analyzing 

the effects of weather on trends in basic building structure and 

equipment.

The second type of data will be the HDD and CDD totals for each building 

by billing period. These totals will be calculated for the appropriate 

billing period. For example, one building may be billed on the 1st of 

the month, while another may be billed on the 5th. Thus, there will 

be different 30-day averages of HDD and CDD for each billing period. 

These data will allow more complete analysis of fuel consumption. 

Analyses of usage patterns and operation characteristics can be under 

taken only if the confounding effects of the weather are controlled.

population size and physical location. In this survey, the States were 

grouped into four regions:

Northeast - Maine, Vermont, New Hampshire, Massachusetts, Rhode 

Island, Connecticut, New York, New Jersey, and

(Note: Alaska and Hawaii are normally considered parts of the western region 

but were not included in the sample for this survey.)

Central Air Conditioning serves all areas of the building that are air 

conditioned. Such systems are specially designed for each building.

Central Heating Systems. This heating equipment category represents two types 

of systems depending upon the location of the system. A central system 

located within the building, (such as a furnace or boiler,) generates the heat 

but depends upon an additional system for distribution of the heat. A central 

system located outside of the building converts energy to a heated substance 

such as steam or hot water which is then distributed to the heated parts of 

the building by a separate system wholly contained within the building.

Combination Air Conditioning Systems. Air coolant systems composed of various 

types of equipment which are either combinations of window units, package 

units, or central systems.

Commercial Buildings. All nonresidential buildings with the exception of 

those where industrial activities occupy more of the total square footage than 

any other type of activity (see Nonresidential Buildings).

Cooling Degree Days refers to the number of degrees the average daily 

temperature is above 65 degrees Fahrenheit. Normally, cooling is not required 

in a building when the outdoor average daily temperature is below 65 degrees. 

Cooling degree days are determined by subtracting the base of 65 from the 

average temperature. For example, a day with an average temperature of 85 

degrees has 20 cooling degree days (85-65=20) s while one with an average 

temperature of 65 degrees or lower has none.

Electricity. Electric power supplied to a building by a central utility via 

underground or above-ground power lines. It does not refer to electric power 

generated onsite for the exclusive use of the building. In this case, the 

fuel used for the generator would be indicated.

Energy Suppliers. The companies which provide electricity, natural gas, fuel 

oil, coal, or other forms of energy to the buildings and to the individual 

customers within the buildings.

Establishment. As defined by the Standard Industrial Classification Manual, 

"an economic unit, generally at a single physical location where business is 

conducted or where services or industrial operations are performed."

Forced Hot Air. A heat distribution system consisting of two types of units 

which distribute heat via fans: (1) a self-contained air handling unit 

serving only a part of the building; and (2) a single central air handling

149
unit separate from the energy conversion system which distributes air 

throughout the building through ducts.

Fuel Oil refers to No. 1, No. 2, or No. 4 grade fuel oil, residual fuel oil ; 

or kerosene that night be burned for space heating or water heating puirpo sw. .

Glass as Percentage of Exterior Surface refers to the proportion of glass I:: 

the exterior wall "structure of the surface.

Heating Degree Days refers to the number of degrees the daily average 

temperature is below 65 degrees Fahrenheit. Normally, heating is not reqtd :i:«r: 

in a building when the outdoor average daily temperature is above 65 degree^! „ 

Heating degree days are determined by subtracting the average daily temper;ttr: 

below 65 degrees from the base 65. For example, a day with an average temper 

ture of 50 degrees has 15 heating degrees (65--50-15), while one with an 

average temperature of 65 or higher has none,,

Hours of Operation During a Typical Week refers to the number of hours per 

week that the building is occupied by regular employees (employees respons.i':: I 

for carrying out the primary activity or activities of the building), ant 

excludes hours when the building is occupied only by maintenance, security, :; 

other supportive personnel. Many buildings do not: maintain the same hours el: 

operation during the year. Alternate schedules were reported for these bull 3 

ings, but for this report "hours of operation" refers to the schedule follow:! 

most often. Other buildings do not have any regular schedule of hours, are 

open intermittently or by appointment only, or are open without being stsffel 

(this last category includes automatic bank tellers and roadside rest step:;;) 

These buildings were recorded as having 0 operating hours, according to the 

definition given by the questionnaire, even though they were not vacant:»

Imputation. A statistical method used to estimate the response to specific 

unanswered questions which should have been answered or were unknown at. the 

time of the interview.

form. It is usually delivered by tank truck and stored near the building In i 

tank or cylinder until used. Propane and butane are liquefied petroleum 

gases.

Master-Metered. The method used by utility companies (i.e., electricity and 

natural gas,) to measure the total volume of energy used by several individ i L 

customers collectively,,

Metropolitan refers to buildings located within Standard Metropolitan 

Statistical Areas (SMSA's) as defined in the 1970 Census. Except in New 

England, an SMSA is a county or a group of contiguous counties which co:atai :,: 

at least one city of 50,000 inhabitants or more, or "twin cities" with a

150
combined population of at least 50,000. The contiguous counties are included 

in an SMSA if, according to certain criteria, they are essentially metropolitan 

in character and are socially and economically integrated with the central 

city. In New England, SMSA's consist of towns and cities rather than counties. 

"Nonmetropolitan" refers to buildings not located within SMSA's as defined in 

the 1970 Census.

Multiple Building Unit. A single building address which at the time of the 

interview was discovered to be two or more separate buildings.

Natural Gas is utility gas supplied by pipeline to individual buildings by a 

central utility company. It does not refer to privately-owned gas wells 

operated by the building owner.

Nonresidential Building. A roofed and walled structure that is used for some 

purpose other than just a residence. The scope of this definition is quite 

broad and includes some buildings that are primarily residential (as well as 

commercial and industrial buildings). The term "residential" applies to 

structures where the primary activity is that of a residence for one or more 

households. Residential buildings were within the scope of the survey if they 

showed evidence of some kind of commercial or industrial activity. For 

example, a residential building, such as an apartment building, which also 

contained some obvious nonresidential activity such as a store or office was 

within the scope of the survey. A private residence which contained an 

office or business, such as a doctor's office in a home, was considered a 

nonresidential building for the purposes of this survey. In order for a 

private residence to have been selected for this survey, it had to have a sign 

(large enough to be visible from the street) advertising the presence of some 

commercial or industrial activity.

Number of People Working in the Building The normal number of people working 

in the building during a typical workday or that which occurs during most of 

the year.

Number of Floors is the count of building levels in the tallest section of the 

building including parking, basements, or other floors below ground level.

Package Units refers to air conditioning units which are built and assembled 

at a factory and installed as a unit to cool all, or portions of, a building.

Self-Contained Heating Units are units installed either in the building or on 

the roof and which generate and deliver heat to the area served.

Separately Metered. This refers to the method in which utility companies, 

(i.e., electricity and natural gas) measure the volume of energy consumed by 

individual customers in a building.

SIC. Standard Industrial Classification codes developed by the U.S. Bureau of 

the Census which categorizes businesses into groups with similar economic 

activities.

151
Special Building List. Part of the sampling procedure entailed locating 

"large" buildings within the sampled PSU's. "Large" buildings were defined asi
