PRELIMINARY CONSERVATION TABLES FROM THE NATIONAL 

INTERIM ENERGY CONSUMPTION SURVEY

Attached is the first report of the Office of the Consumption 

Data System, Office of Program Development, Energy Information 

Administration, presenting preliminary data from the National 

Interim Energy Consumption Survey (NIECS). The focus of this 

report is the conservation activities performed by households 

since January 1977, and the status of households with respect 

to insulation, storm windows, and other energy conserving 

characteristics. These tables are from preliminary data files. 

Therefore, the tables are in weighted percentages rather than 

weighted numbers. The tables will be reissued in final form 

in the fall of 1979.

Included in the report is a summary, a description of how the 

survey was conducted, preliminary sampling errors, and a 

glossary of terms.

The following EIA staff members have contributed to this 

project: Kenneth Vagts Director, Office of the Consumption 

Data System; Lynda Carlson overall manager for the residential 

sector; Wendel Thompson NIECS survey manager; Lynn Handler 

packager for the report and analysis author; Bruce Egan, 

Leigh Carleton, and Mike Lawrence table design and generation; 

Mike Maloney--systems design and data processing; Tom Woteki and 

Stuart Cohen statistics; Diane Good and Dotty Tate secretarial 

and clerical work. The survey fieldwork was conducted by Response 

Analysis Corporation.

Preliminary Conservation Findings

This report consists of four sets of conservation related 

tables. The first set presents statistics on the presence 

of storm windows and doors and insulation in the housing 

inventory for the winter of 1978-1979. The remaining three 

sets of tables are concerned with conservation additions 

made during three time periods: April 1977-December 1978 

(the period of eligibility for a 1978 energy tax credit), 

and the two calendar years of 1977 and 1978.

Each set consists of eight tables. Conservation inventories 

and additions are crossed by: census region (plus rural/ 

urban), type of heating fuel, weather zones, type of building 

structure, year house built, type and presence of air-condi 

tioning, family income, and value of residence.

The sample base for this report is 3,448. This figure includes 

all occupied residential buildings containing between one and 

four housing units in the National Interim Energy Consumption 

Survey (NIECS). Although, buildings with five or more housing 

units were included in the survey, statistics on these units 

will be presented in future reports. Residents of these 

buildings were not asked about conservation additions or about 

the presence or absence of insulation. Therefore, they have 

been omitted from this report.

A series of weights was applied to the sample units to allow 

estimates to be made of the entire population. After weighting, 

the estimated population was equal to 67.6 million housing 

units. The 100 percent figure given in the upper left hand 

corner of each table represents this weighted number.

The first set of tables show household inventories of conser 

vation items. Displayed here are statistics on storm windows 

and doors; presence, type, and quantity of attic insulation; 

wall insulation; and whether or not rooms were closed off 

(left unheated) during the winter of 1977. The inventory 

figures derived from the NIECS are not strictly comparable to 

those published in the latest (1976) Annual Housing Survey 

(AHS). The AHS data were for 1976 and the NIECS data were 

collected during the winter of 1978-79. In addition, the AHS 

limits its sample to occupied single-family homes. When the 

NIECS sample was adjusted to correspond to that used by the 

AHS, significant differences were found between the percentages 

of housing units with storm windows and doors. No significant 

difference was found in the two surveys between the percent 

of housing units with attic insulation.*

*The estimates and sampling errors given here are preliminary 

and subject to revision. Sampling errors have been estimated 

conservatively. For a discussion of sampling errors and a 

table for their computation, see page 67-
Forty percent ( + 3) of the NIECS households had storm windows 

on all of their~windows, 36 percent (j^ 3) had storm doors, 

and 68 percent (+ 3) had some attic insulation. Approximately 

one-third of the households had closed off one or more rooms 

during the winter.

The second set of tables gives statistics on conservation 

additions for the period of eligibility for an energy tax 

credit on 1978 Federal income taxes. In order to qualify 

for an energy tax credit, two criteria must be met. First, 

to be eligible, an addition had to have been made between 

April 20, 1977 and December 31, 1978. Second, additions were 

only considered to be eligible if they were made to houses 

built (or substantially completed) before April 20, 1977. 

The eight tables in the second section give three classifica 

tions of eligibility. Eligible additions were made in the 

appropriate time frame and to houses built in 1976 or earlier. 

Ineligible additions were made during the right time, but to 

houses built in 1977 or later. Eligibility could not be deter 

mined for those who did not know when their houses were built.

Some sort of conservation related equipment or insulation was 

added to nearly half of the housing units in the sample. 

Slightly more than 20 percent of the households had made more 

than one addition. Most additions were made in the area of 

inexpensive insulation, specifically: caulking (24 percent), 

plastic covering (15 percent), and weatherstripping (13 per 

cent) . Almost 40 percent (+ 3) of the households made an 

addition of this type. Wore expensive insulation additions 

or any kind of equipment additions were undertaken by very few 

respondents. Between 7 and 8 percent (+_ 2) of the households 

had added roof or attic insulation, storm doors, or storm 

windows.

The third and fourth sets of tables present statistics on 

conservation-related additions made during 1977 and 1978. 

In each of the two calendar years presented here, approximately 

one-third of the households added some sort of insulation or 

equipment. Nearly all of the additions made were in the cate 

gory termed "inexpensive insulation". Twenty-eight percent 

(+_ 3) of the households made an addition of this type in 1977 

and 25 percent (+_ 3) added inexpensive insulation in 1978. 

Within this category, the most popular additions included 

caulking, plastic coverings, and weatherstripping. In each 

of the two years, approximately 4 percent (+_ 1) of the house 

holds added storm windows, storm doors, or attic insulation.
When the NIECS sample was altered to correspond to that used 

in the AHS, differences in the percentages of storm windows 

and doors added became insignificant. With the exception of 

the previously mentioned, minor, very inexpensive additions, 

little was done in the way of conservation additions over the 

two year period.

These are preliminary figures subject to revision. Sampling 

errors have been calculated conservatively. Therefore, 

conclusions reached from these data may be subject to revision.

Preface

The tables presented are based on a sample size of 3,448 

housing units. Percentages have been weighted to represent 

a universe of 67.6 million housing units. Each housing unit 

appears in more than one row, with the result that each sub 

total will sum to 100 percent (taking rounding errors into 

consideration). In tables 9-16, the insulation and equipment 

items listed are not mutually exclusive. As a result, these 

items may sum to more than the "yes" and "yes, eligible" 

subtotals.

I/ HOUSEHOLD. Includes all the individuals who occupy a 

housing unit. By definition, the count of households 

is the same as the count of occupied housing units.

2/ NOT APPLICABLE/NOT REPORTED. Not applicable indicates 

that theitem wasnot relevant. (Renters did not report 

a value of residence, and households not occupying their 

housing unit during the previous winter did not report if 

any rooms were closed off.) "Not reported" includes any 

of the following responses: no answer, don't know, refused, 

and not applicable (when not shown separately).

_3/ HOUSING UNITS. Includes only occupied housing units

intended for,year-round occupancy, and excludes buildings 

with five or more units. Please refer to the glossary 

for a more detailed definition of housing units.

4/ STORM WINDOWS/STORM DOORS. Includes storm doors or storm 

windows, as well as, thermopane glass, double glass, or 

any other kind of insulating glass.

5/ HEATING DEGREE DAYS (HDD)/COOLING DEGREE DAYS (ODD).

Refers to the weather zones indicated on the map of the 

United States on pages 7 and 25. Please refer to the 

glossary for a more detailed explanation of heating and 

cooling degree days.

NATIONAL INTERIM ENERGY CONSUMPTION SURVEY 

Introduction

The National Interim Energy Consumption Survey (NIECS)* was 

designed by the Energy Information Administration (EIA) to 

provide information related to energy consumption by the resi 

dential sector. This survey, along with analogous studies for 

the commercial and industrial sectors, will enable the analysis 

of comprehensive consumption patterns for the United States.

Information on energy use in the residential sector was 

collected at the household level. A representative (national) 

sample of households was selected in the 48 contiguous states 

plus the District of Columbia. The data on actual energy con 

sumption was obtained from fuel records maintained by the 

household's fuel suppliers. An inventory of motor vehicles 

used by the household was also included in the survey.

Data Collection

Response Analysis Corporation (RAC), Princeton, New Jersey, 

conducted the interviews. A total of 4,849 housing units were 

drawn in the original sample. Of these, 342 were ineligible 

for this survey because they were either vacant or seasonal 

units (the occupants did not live in them for more than half 

of the year). Of the 4,507 eligible units, interviews were 

obtained from 3,843 households, yielding an initial response 

rate of about 85 percent. Subsequently, mail questionnaires 

were sent to the 664 households that were not interviewed. 

Completed mail questionnaires were received from 239 of these 

households. This additional effort increased the response 

rate by around 5 percent. The responses to the mail question 

naire are not included in the data presented here. Consequently, 

these results must be viewed as being preliminary. The primary 

reason for the lag in the processing of the mail questionnaires 

is that they are an abbreviated form of the regular question 

naire. An imputation process (hot decking) is being employed 

in order to obtain a completed version. This implementation 

will require some months of work.

Initial household contacts were begun in October 1978. The 

50-minute interview covered: structural features related to 

energy, such as size, insulation, and openings; the heating 

and cooling systems and the fuels used in these systems;

*Not to be confused with NIEC--the National Energy Information 

Center which is EIA's public information office.

47
energy conservation efforts; information on household appli 

ances and vehicles; and demographic data on household members. 

At the conclusion of the interview, respondents were asked 

to sign waivers authorizing RAG to obtain their records of 

fuel consumption from their fuel supplier.

Most of the 200 interviewers employed by Response Analysis 

Corporation had had previous survey experience. Training 

for KIECS was done by mail, using a 59-page instructional 

booklet. The booklet included specific procedures for con 

ducting this survey and provided guidelines on how to handle 

various interpretations of questions. A practice interview 

and a quiz on the instructions were also parts of the train 

ing. Ten percent of the interviewers were checked to insure 

that they conducted an interview in person.

Sample Design

The NIECS sample is a representative area probability sample 

consisting of 103 primary sampling units (PSU's). These PSU's 

were selected from approximately 1,140 PSU's that collectively 

form a mutually exclusive and exhaustive division of the con 

tiguous United States. Each PSU is a well-defined geographic 

unit, usually consisting of one or more counties. Based on 

the 1970 Census, PSU sizes range from a population of 50,000 

to approximately 3,300,000. Region, metropolitan status, and 

size classification were the primary considerations in the 

selection of the sampled PSU's.

Within each PSU, secondary sampling units (SSU's) were defined. 

Based upon 1970 Census counts, 400 SSU's were selected from 

the 103 PSU's. Each of these SSU's contained approximately 

2,500 persons and consisted of one or more blocks in urban 

areas and one or more enumeration districts in the non-urban 

areas. An additional 56 FSU's were selected independently. 

These 56 SSU's comprised a probability selection of areas that 

had undergone substantial new construction since 1970. Inde 

pendent sources (Rueben K. Donnelly address lists and county 

data) were used to update the population for these SSU's. 

Failure to update the estimated population for these areas 

would have increased the chance of selecting an inordinate 

number of households in an SSU.

Within each SSU, a subdivision was made. Census block 

statistics and rough field counts were used to break up each 

SSU into segments. These segments were formed so that they 

ultimately contained about 25 households. Finally, a sample 

of 10 or 11 households was selected to be visited. Thus, 

within each SSU 10 or 11 households were sampled, within each 

PSU an average of 40 to 45 households were sampled, and 

nationally, about 4,500 units were sampled.

48
Three checks were done to verify the coverage or completeness 

of the survey process. First, 100 prelisted sample locations 

were relisted by a third party to check the completeness of 

the original listing. Second, sample locations that had an 

unusually high vacancy rate were re-examined to determine 

whether interviewers misclassified a unit as vacant. Third, 

in order to increase the precision of our estimates, a tech 

nique called ratio estimation was employed. Ratio estimation 

uses known, accurate distributions of the population and 

revises survey estimates by applying a factor to each house 

hold.

These adjustments took place in two stages for the NIECS. 

The first stage factor was a ratio of the total number of house 

holds in each region by fuel type to an estimate of the number 

of households in each category. Only the PSU's in our sample 

and their appropriate weights were used. The figures used in 

both the numerator and denominator were based on the 1970 

Census. The implementation of this factor reduced the amount 

of variance due to the sampling of PSU's. The second stage 

factor adjusted data from the survey to independently derived 

current estimates of the number of households for specified 

groups. The ratio adjustment was calculated for each region 

by type of community. The second stage factor reduced both 

the between PSU variance, as in the first stage, as well as, 

the within PSU variance.

Minimizing Nonresponse

The Office of Federal Statistical Policy and Standards 

encouraged an analysis of the effect of nonsampling error 

in the NIECS. The previously mentioned coverage check and 

an intensive effort to minimize nonresponse were the outcome 

of several meetings and memoranda dealing with the nonsampling 

error issue. Many of the following procedures were used to 

test the feasibility of a multi-wave, multi-contact approach 

and may or may not be used in the larger Residential Energy 

Consumption Surveys (RECS). Most households received two 

letters in October 1978, prior to the interivew. An EIA 

letter stressed the importance of the survey and a RAG letter 

announced the upcoming arrival of the interviewer.

To elicit rapport and cooperation, a $2 incentive was given 

to the respondent before the interview. Interviewers made 

up to three call-backs at different times of the day and 

and week. They also queried neighbors as to the most opportune 

time to contact the respondent. The use of incentives will 

be analyzed in order to determine their utility and whether 

they should be used in the RECS.

49
A second wave was conducted in December 1978 to contact 

households that were not available during the first wave and 

to convince the first-wave refusals to reconsider. A second 

set of letters preceded the second-wave interview as well. 

A different interviewer was assigned and endeavored to com 

plete the interview by making up to four contacts.

A third wave followed in January 1979. This was an effort 

to reach nonrespondents in 14 sample locations that had low 

interview completion rates.

In a final attempt to complete an interview, an abbreviated 

version of the questionnaire, adapted for self-administration, 

was mailed to nonrespondents in February 1979. The $2 incen 

tive was included in the mailing.

Additional Survey Components

One purpose of the NIECS was to test the procedures and 

methodology for REGS. Three small studies, in addition to 

the basic NIECS survey, are also being conducted. These 

studies will be used to determine what additions and modi 

fications should be made for REGS.

A transportation panel consisting of a subset of the NIECS 

sample began in June 1979. Participating households are asked 

to keep a log of their fuel purchases and odometer readings for 

a two-month period. The panel consists of 500 to 1,000 house 

holds reporting each month. Separate tabulations of these 

data are planned.

Fifty NIECS houiseholds will be selected to be part of an 

energy assessment study. Trained technicians will analyze the 

energy-related components of a house. Exact square footage, 

temperature distribution in various parts of the house, pre 

sence of insulation, and features of major appliances (includ 

ing heating and cooling equipment) will be surveyed. Precise 

procedures are still being developed for this study.

When renters did not pay directly for their fuel costs, an 

interviewer contacted the apartment manager by telephone to 

ask what space and water heating fuels were used in the 

apartment building. When these data become available, they 

will be incorporated into the NIECS data set.

50
Data From Nonhousehold Sources (Fuel Suppliers)

Respondents in 95 percent of the interviewed households signed 

waivers to permit fuel suppliers to give Response Analysis 

Corporation the monthly record of their past year's fuel 

purchases. The data contained both the amount sold and the 

price of the fuel. The suppliers were contacted between 

March and May 1979 and were asked to supply fuel billing 

information for a 12-month period.

In order to attain the highest response rate possible, the 

following procedures were used:

o Letters were sent to each company after RAG

located the person who would act on the request 

for fuel bills. Followup telephone calls were 

made to insure the receipt of the letter and to 

help with any problems that may have arisen. 

Response Analysis Corporation also personally 

visited several companies to offer assistance.

o Some fuel oil and liquid petroleum gas (LPG)

suppliers provided the fuel purchase information 

over the telephone. The telephone was adequate 

for these types of suppliers because each com 

pany supplied data for only a few customers and 

the fuel records were not as detailed as records 

for electricity and natural gas sales. About 600 

of the approximately 800 fuel suppliers contacted 

in this survey were fuel oil or LPG distributors.

One unique aspect of this survey was the opportunity to obtain 

electricity and natural gas data for households that did not 

complete the interview or did not sign the waiver. Utilities 

would not supply individual household data without a waiver, 

but did supply aggregate data for groups of nonrespondents. 

This information provided a rare opportunity to analyze the 

bias introduced by nonresponse and to improve the accuracy 

of consumption estimates in the residential sector.

Master-metered apartments presented a problem since the fuel 

consumption costs are embedded in the apartment building's 

fuel bill. To collect data concerning apartment buildings and 

their use of energy, 50 buildings in the NIECS sample were 

selected for additional followup. This information will be 

used to allocate energy costs to individual apartments.

51
Weather Data

The first type of temperature data used was the 45-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 household was located.

These data will aid in analyzing the effects of weather on 

personal decisions to make changes in basic housing structure 

or equipment. The second type of data used were HDD and CDD 

totals for each billing period. These data will allow more 

complete analysis of fuel consumption.

Weather conditions will have to be calculated for the 

appropriate billing period. For example, one household may 

be billed on the 1st of every month, while another may be 

billed on the 5th. Obviously, there will be different 30-day 

averages of HDD and CDD.

Editing Completed Questionnaires

Interviewers mailed the completed questionnaires to Princeton, 

New Jersey, where they were reviewed for completeness and 

correct identifying information. This manual edit was seg 

mented and each part was worked on separately. Telephone 

calls were made to clarify ambiguities in the data.

A machine edit checked for reasonable values, proper skip 

patterns, and logical consistencies.

All key punching was verified.

NIECS Glossary

- Co nd^t-io Yi-inQ is cooling air by a refrigeration unit. 

It does not include fans, blowers, or evaporative cooling 

systems which are not connected to a refrigeration unit.

Air conditioning units which are not currently in working 

condition or not used, but are in place in the housing 

unit, are included.

B/cll-ing Tnn.j.od refers to the time between meter readings. 

It does not refer to the time the bill was sent or when the 

payment was to have been received. In some cases, the bil 

ling period is the same as the billing cycle which corresponds 

closely (within several days) to meter reading dates. For 

fuel oil and LPG, the billing period is the number of days 

between fuel deliveries.

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 deter 

mined by subtracting the base of 65 from the daily average 

temperature. For example, a day with an average temperature 

of 85 degrees has 20 cooling degree days (85-65=20), while one 

with an average temperature of 65 degrees or lower has none.

VooiA that go outside or to an unheated area, such as an 

unheated porch, garage, attic, or basement, are included.

credits obtained are acceptable in the regular school system.

Persons who have attended "post graduate" high school courses 

after completing high school, but have not attended college, 

are considered to be "Twelfth" grade graduates.

Persons who have attended more than four years of college, 

or who have attended professional schools (law, medicine, or 

dentistry, for example) are considered to have a college educa 

tion plus graduate or professional schooling after completion 

of four years of college.

The equivalent grade of the regular American school system 

is assumed for a person who obtained his formal education 

through other systems.

For persons who skip or repeat grades, the highest grade 

attended is accepted.

Peg-free Pat/a are the number of degrees of daily average 

temperature is below 65 degrees Fahrenheit. Normally, heating 

is not required in a building when the outdoor average daily 

temperature is above 65 degrees. Heating degree days are 

determined by subtracting the average daily temperature below 

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

average temperature of 50 degrees has 15 heating degree days 

(65-50=15), while one with an average temperature of 65 or 

higher has none.

Use of the Generalized Variance Tables

The following tables allow the user to roughly estimate the 

standard error of estimated percents calculated on the 

National Interim Energy Consumption Survey (NIECS) data. 

The entries in the table were derived using a combination 

of design effects that resulted from Annual Housing Survey 

(AHS) figures (the AHS and the NIECS are quite similar in 

design), the average size of the ultimate sample within a 

primary sampling unit (PSU), the variation of this average, 

and the average number of secondary sample units selected 

in a PSU.

Two tables are shown. One is to be used for characteristics 

that are not substantially effected by the cluster design and 

the other is to be used for characteristics that are effected 

by clustering.

In order to use these tables, the following procedures should 

be followed:

o Determine which table is to be used

o Determine how many households in the sample are 

eligible to have the characteristic. This will 

determine the appropriate row to be used.

o Using the table of estimates, determine what

percentage was estimated for this characteristic. 

The appropriate entry in the table is now avail 

able.

o Since these tables are based on one standard 

deviation, a 95 percent confidence interval 

would equal twice the value in the table.

An example is as follows:

Suppose, we discover that 500 households are in non-SMSA areas 

in the West and we wish to see how many have attic insulation. 

Using the appropriate table, we find out that 5 percent of 

the households have attic insulation. We also determine that 

attic insulation is effected significantly by the clustered 

design. We then use the lower table and the correct entry 

(using 500 for the row and 5 percent for the appropriate 

column) is 2.0. This means that there is a 95 percent pro 

bability that the percent of households having attic insulation 

in non-SMSA's in the West is between 1 and 9 (5+ 2(2.0)).
