Geothermal & Ground Source Heat Pumps
Baseline
- Heat pumps having supplementary electric-resistance heat must have controls that prevent unnecessary supplemental heat operation. [COMPMOD]
Stretch
- Systems options include but are not limited to unitized heat pumps (PTHP, HPAC 2.0, CH4A window-integrated heat pump), centralized systems (VRF/VRV), and geothermal or ground-source heat pumps.
- Refer to NYC Pre-feasibility web map to determine if the property suite for geothermal energy conversion.
