Direction for further analysis

Decision Details

Clarify eligibility requirements for (central system) heat pump UES measures so as to limit eligibility to single speed and two speed compressor systems.

BPA is planning lab and field tests of the new generation of central heat pumps with variable speed compressors. Results are expected in 2013, at which time the RTF may review a proposal for a UES measure for those units. In-situ duct system efficiency is the primary unknown at this point.
