Adopt the subcommittee recommendation that, by default, for purposes of SEEM calibration, the RTF assumes the fraction of total energy that goes to heating is the same in poor-VBDD homes and good-VBDD homes. For single-family homes, this assumption, together with the results of the annualized energy analysis, implies that poor-VBDD sites use 14% less heating energy than good-VBDD homes.
