Note: As of the December 2023 RTF decision both the conversion and upgrade options within this measure are "Under Review".
This measure is for the conversion from an electric forced air furnace to an ASHP. The ASHP can either meet the Conversion or Upgrade efficient condition. These two applications are designed to be additive as applicable. If the efficient case meets the Conversion criteria the savings would be for the Conversion application only. If the efficient case meets the Upgrade criteria the savings would be for the Conversion and Upgrade applications combined.
This measure uses the same methodologies as the single family ASHP measure but uses manufactured home data from RBSA I and II as well as the manufactured home specific SEEM calibration.
The conversion measure is the conversion from an electric forced air furnace to an 8.5 HSPF heat pump. Savings are based on weighted average results from evaluations. All applications were set to Under Review at the December 2022 RTF meeting due to the variability found between program evaluation results.
The upgrade measure is upgrading from an 8.8 HSPF heat pump to a variable capacity heat pump. Savings are based on calibrated SEEM runs. The Upgrade application is set to Planning due to less certainty in modeling of SEEM and general uncertainty around VCHPs. All applications were set to Under Review at the December 2023 RTF meeting.
