Technical Assistance & Demonstrations

The California Housing Partnership works directly with nonprofit affordable housing owners and public housing authorities to help them identify creative ways to finance energy and water retrofits and clean energy improvements for their properties. This involves educating owners about the programs and opportunities for incentives available to them, as well as developing innovative demonstration projects to explore new technologies, financing tools and business models for affordable rental homes.

Low-Income Weatherization Program

The California Low-income Weatherization Program for Multifamily Properties (LIWP) installs rooftop solar systems, solar hot water heater systems and weatherization measures on low-income multifamily properties in disadvantaged communities to reduce greenhouse gas emissions and save energy.

The California Housing Partnership works closely with the Association for Energy Affordability to lead the outreach effort for LIWP.

Demonstration Projects

The California Housing Partnership partners with mission-aligned organizations to demonstrate innovate energy and water technologies, business models and financing solutions for affordable rental homes.

In 2017, we published a case study on our Santa Monica test of financing energy savings through on-bill repayment, rather than through a loan. Our findings helped to shape California’s statewide on-bill repayment pilot, which launched in 2018.
