AI summary The Evaluator conducted a literature review, engineering calculations, and used program data to assess unitary savings values for products installed through the Efficient Product Installation program, reviewing single-family homes and apartments separately, and consulting technical reference manuals and public evaluations from similar jurisdictions.

Tracked Savings ENS uses unitary savings values to track the energy and peak demand savings associated with wood and pellet stoves. The unitary savings values are based on HOT2000 energy models created for the 2013 evaluation. The baseline...

AI summary ENS uses unitary savings values based on HOT2000 models to track energy and peak demand savings from wood and pellet stoves. For participants with air-source heat pumps (ASHPs), these values are adjusted by dividing by a COP of 2.1 from the Pennsylvania PUC's TRM. Peak demand savings are assumed to be the same for ASHP and electrical resistance baselines.
