- March 2, 2006

## Key Residential Measures

- Lighting
- Heat Pumps
- Duct Sealing
- Weatherization
- New Construction - stick built and manufactured
- Appliances

## Residential Lighting

- ENERGY STAR® CFL’s at $2.50 per socket (screw-in or pin based, 5 watt minimum size)
- Up to $4 in hard to reach market segments (project approval required)

## Air Source Heat Pumps

- Reimbursement based on incremental savings of upgrading to a high efficiency model heat pump.
- Distinctions on when a house was built are no longer required, but different levels of credit are offered based on the home’s climate zone and whether the home’s duct system is determined to be inside or outside the heated envelope.
- Minimum SEER 14, HSPF 8.5, and PTCSTM commissioned heat pump certification is required.

## Air source heat pumps, cont.

- PTCS duct certification required on homes with ducts outside the heated envelope.
- SEER 14, HSPF 9.5, and PTCS certified heat pumps qualify for a higher credit or reimbursement.
- Heat pump must be installed by a PTCS certified contractor to PTCS standards.

## Reimbursements for heat pumps

## Weatherization

- $0.30 cents per kWh for measures on RTF list
- Attic, wall, and floor insulation
- Air Sealing
- Window upgrades
