Notes:

1)    Source: 2005 RECS Averages are for single-family houses with the characteristics described in Table 24.

2)    All energy consumption values are presented in Mbtu in the RECS dataset. Additionally the energy consumption output from the DOE 2.1E building simulation model is also presented in Mbtu. Therefore we retain energy consumption as Mbtu, and convert to utility units (kWh, therm, etc.) for presentation to the user, using the fuel-specific conversion factors found in Table 2 above.

3)    Secondary heating is indicated for climate zones 9 and 16.
