### APPENDIX 7

- D. WEATHER DATA AND TEM PERATURE PARAMETERS

7- D.1 IN TRODUCTION

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 perform ed:

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

tempera ture 65 o 

### F for year 2005 for these weather stations. 3 

### 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 valu es and the HDD and CDD values.7

### 7-D.2.1 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 CDD CDD

2 1 2

2 1 2



### Where:

HDD 1 

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

HDD 2 

### = heating degree days from RECS 2005 data,

CDD 1 

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

CDD 2 

### = 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.
