West Penn Power AMENDED Program Year 3 Final Annual Report

4 Residential Energy Efficient HVAC Equipment Program
This program provides incentives supporting implementation of contractor-installed HVAC, or other
eligible systems in existing or new residential buildings. This program involves promoting the sale of
high-efficiency, ENERGY STAR® compliant equipment through installation contractors selling to
residential customers who are replacing existing home HVAC equipment. The program will replace
existing or standard HVAC equipment in residential applications with heating and cooling systems
approved by the ENERGY STAR® program of the US EPS/DOE.
The program also provides incentives for maintenance (tune-ups) of existing central air conditioners or
heat pump equipment, and will offer an incentive toward replacement of furnace fans meeting Energy
Star efficiency guidelines.
4.1 Program-Updates
On October 28, 2011, the Commission approved the Petition of West Penn Power Company, for
modifications to its EE&C Plan: Immediately following approval, the Company began implementing the
Amended EE&C Plan changes, which included an increase in rebate values for both the replacement and
maintenance of HVAC units.
4.2 Impact Evaluation Gross Savings
Savings associated with HVAC equipment types are estimated using a partially deemed approach, with
the kWh reduction determined using deemed hours of operation of the equipment determined by
which reference city the installed location is closest to an nameplate information from the equipment
regarding unit capacities and efficiencies. For all new HVAC systems, the baseline efficiencies are
stipulated in the PA TRM and are in accordance with Federal codes and standards. Savings associated
With HVAC maintenance, or tune-ups, are estimated using the PA TRM protocols for savings calculations.
The desk review indicated that the reported gross savings were under-calculated and adjustments were
made based on model/make specific capacities, efficiencies and a more nuanced mapping of home to
the TRM cities for EFLH. This resulted in desk review realization rates of 1.216 and 0.697 for kwh and
kW respectively.
The impact evaluation for the HVAC equipment component of the program included verification of
installation through web surveys and'a 1.00 realization rate was determined. The findings parallel the
2011 realization rate, which included verification through a web survey and onsite inspections to verify
installation and nameplate information for comparison to program records and the tracking system.
The EM&V team determined a realization rate of 0.855 for the HVAC tune-up.
The combined desk review and survey verification realization rates for this program are 1.216 and 0.697 '
for kWh and kW respectively.
