APPENDIX 7-D.WEATHER DATA AND TEMPERATURE PARAMETERS 

7-D.1 INTRODUCTION 

To facilitate more precise analyses, DOE matched RECS households with National 

Oceanic and Atmospheric Administration (NOAA) weather station locations. This match 

allowed DOE to determine monthly cooling and heating degree-days, compared to the yearly 

averages available from the RECS survey. These values were used for a variety of purposes. 

7-D.2 OUTDOOR TEMPERATURE DERIVATION 

RECS 2005 provides yearly averages for heating and cooling degree-days but no data on 

a monthly scale. To find more precise temperature information for the households in the RECS 

sample, DOE developed an approach to assign a physical location to each RECS household. The 

following steps were performed: 

1.	 DOE assembled weather data from 282 weather stations that provide annual average 

outdoor air temperatures.1, 2 The annual average outdoor air temperatures represent 30­

year averages. DOE also gathered the heating and cooling degree-days at base 

3 temperature 65 o

F for year 2005 for these weather stations. The 2005 heating and 

cooling degree days match the period used to determine the degree-days in RECS 2005. 

2.	 RECS reports both heating degree-days (HDD) and cooling degree-days (CDD) to base 

temperature 65 o

F for each housing record. DOE assigned each RECS household to one 

of the 282 weather stations by calculating which weather station (within the appropriate 

census region or large state) gave the best linear least squares fit of the RECS data to the 

weather data. 

Figures 7-D.2.1 and 7-D.2.2 show the relationship between the gathered mean 

temperature values and the HDD and CDD values.

7.D.2.2 Imputation Method 

 To determine household location, DOE matched the RECS 2005 combinations (255 

individual combinations of Census Divisions plus 4 large states, together with the HDD and 

CDD data) to U.S. weather data. DOE used the U.S. weather station closest (or with minimum 

“distance”) from the RECS 2005 data combination. The following equation calculates the 

“distance” between the U.S. weather data and RECS 2005 data: 

" Distance " = ( HDD − HDD ) 2 + (CDD 2 − CDD ) 2

2 1 1 

 Where: 

 HDD1 = heating degree days from U.S. weather data, 

 HDD2 = heating degree days from RECS 2005 data, 

 CDD1 = cooling degree days from U.S. weather data, and 

 CDD2 = cooling degree days from RECS 2005 data. 

 Figures 7-D.2.3 and 7-D.2.4 show the relationship between the imputed mean outdoor air 

temperature values and the RECS 2005 HDD values.

 Table 7-D.2.1 shows the imputation results for all RECS locations. Note that some

weather station data matches with several of the RECS 2005 255 HDD & CDD combinations.

Table 7-D.2.2 shows a subset of the data matches.
