Room heat pumps, such as portable heat pumps, window shaker style or "saddle bag/no gap" style. BPA has a qualified measure (new as of 10/1/2026) that could be a useful starting point. That measure is only for "no gap" models which I assume have the best year-round persistence. These may also be being purchased primarily for cooling, then having a significant add on benefit in the heating season displacing gas. We'd like to see RTF measure applications for a range of existing conditions including displacing gas. BPA's measure is for displacing electric resistance heat only, but if midstream or retail programs this may not be possible to verify. There are indications that Oregon legislature or other gov't policies might require programs to support cooling access via heat pumps regardless of existing condition. Having an RTF measure for this may support work to further study savings, use patterns, and potential of this equipment. One barrier to this equipment is compatible windows and consumer education about this prior to purchase.
