SEEM Phase II Calibration for Manufactured Homes. Regional Technical Forum August 12, 2014. Phase II general approach. Phase I gave us total heating energy estimates for homes with clear VBDD signatures. RTF measure savings needs average electric energy savings for all program homes.
SEEM Phase II Calibration for Manufactured Homes

Sites excluded from Phase-II regression for a few reasons…
Note: We don’t remove sites with non-electric heating fuels since our goal is to estimate those features’ effects.
By the numbers….
All else equal, VBDD-electric in homes with feature differ from that of homes without feature by a factor of .
Hence, feature associated with adjustment to VBDD kWh.
Non-electric fuels account for 23.7% - 5.7% = 18% gap between good-VBDD and poor-VBDD sites.
That’s more than the 14% figure we got from annualized energy.
Propose to accept 18% figure and make no additional VBDD adjustment. (So non-electric fuels account for differences between good-VBDD and bad-VBDD sites, and they differ by 18%).
0.0% of Phase I kWh
7.9% of Phase I kWh
92.1% of Phase I kWh
I, ________, move that the RTF adopt the phase II calibration for manufactured homes as described above and summarized below.
