Low-Income Weatherization Program

The Low-Income Weatherization Program’s (LIWP) Multi-Family Energy Efficiency & Renewables Program provides technical assistance and incentives for the installation of energy efficiency measures and solar PV in low-income multi-family dwellings serving priority populations. These projects reduce residential energy demand and GHG emissions, lower energy costs for low-income residents, and reduce owner operating costs.
