The high-efficiency HVAC rate is available
to commercial customers that meet one of the
requirements below:
1. Use either an air-source or ground-source
heat pump as the only source of heating and
cooling in their facility.
2. Use an electric water heater (usually connected
to a desuperheater on the heat pump) as the
only source of water heating.
3. Receive prior approval of the equipment
from RPU. Note that equipment must be rated
by the Air-Conditioning, Heating, and Refrigeration
Institute (AHRI) and meet the minimum efficiency
standards listed below.
General Service- High
Efficiency HVAC (Loads
less than 75 kW)
Minimum Qualifications for Air Source
Heat Pump (ASHP) Systems:
Minimum Qualifications for Ground Source Heat
Pump (GSHP)/Geothermal Systems*:
(1) SEER: Seasonal Energy Efficiency Ratio
(2) EER: Energy Efficiency Ratio
*Water-to-Air Heat Pumps: The efficiency ratings
are determined using the Air Conditioning,
Heating, and Refrigeration Institute’s
(AHRI) directory, which may be found at www.ahridirectory.org.
EER rating is at ARI/ISO 13256-1 cooling conditions
of 77°F entering water temperature and
80.6°F dry bulb/66.2°F wet bulb entering
air temperature (ground loop heat pump).
*Water-to-Water Heat Pumps: The efficiency
ratings are verified using manufacturer specifications
which clearly demonstrate the Entering Water
Temperature (EWT), Gallons Per Minute (GPM)
water flow, and the associated EER rating.
EER rating is at ARI/ISO 13256-2 cooling conditions
of 77°F entering water temperature and
53.6°F leaving water temperature (ground
loop heat pump). Please include manufacturer’s
specification sheets verifying this information.
Note: Other all-electric HVAC systems may
be considered for this rate if they meet the
stated efficiency standards. To have a system
considered, customers must submit an engineering
analysis documenting the efficiency of the
system.
