Green Affordable Housing: Solara

THE PROJECT

California’s first apartment community designed to be fully powered by the sun. Completion date for the affordable housing project: 2007.

OUR PARTICIPATION

Through our Greening of Affordable Housing Initiative, we work extensively with nonprofit community development corporations, architects, financial institutions, and government agencies at the local, state, and national level. Global Green USA was the Green Building/Renewable Energy Advisor on the project.

PROJECT DETAILS

SOLARA's 141 kilowatt, grid-tied photovoltaic (PV) system supplies power separately to each of the project’s 56 energy-efficient apartment units, community center, and common areas. While SOLARA was built exclusively with easily obtainable off-the-shelf technology, its major breakthrough was financial. By taking advantage of funding sources available to most new affordable housing projects in California, the development team was able to cover more than 92% of the cost of the $1.1 million solar system with incentives and create a business model that can be replicated in affordable housing developments across the state.

SOLARA's energy efficiency and renewable energy package may be its most obvious green feature, but the foundation of SOLARA’s success as a green affordable housing project lies in the design team’s holistic approach to sustainable development. The team focused on core elements such as community access and walkability, indoor environmental quality, water efficiency, and resource conservation throughout the design and construction process. The result is proof that quality, innovative, and environmentally-friendly housing can be accessible to everyone.
