This case study discusses California’s Multifamily Affordable Solar Housing (MASH) program. MASH has brought solar energy to thousands of multifamily building owners and tenants across the state, allowing them to reduce carbon pollution and benefit from lower energy costs. MASH uses financial incentives and an innovative billing arrangement to help overcome the challenge of motivating building owners to invest in energy solutions for tenant units where the tenants pay their own utility bills – a barrier typically referred to as a “split incentive.”
Read the case study to learn about MASH’s key features, approach, partners, funding sources, and achievements, as well as their keys to success and tips for replication and sustainability.You will need Adobe Reader to view some of the files on this page. See EPA’s About PDF page to learn more.
