A four-year $3.8M effort funded by the California Energy Commission will convert the William Penn Hotel (a historic, mixed-use building with low-income housing) into a showcase of innovative Zero Net Energy (ZNE) building design. The site includes a theater, offices and housing for ninety-one, low-income residents — including many formerly homeless and at-risk adults. The project is seeking innovative solutions and products to address a high-density urban housing environment in a high performance building. Project partners include Chinatown Community Development Center, RMW Architects, Integral Group, National Renewables and Energy Laboratory, and the San Francisco 2030 District.
