Ship Yard Becomes Energy Efficient Housing Site

Land that used to bustle with Navy and private ship building will soon host solar photovoltaic (PV) friendly and energy efficient housing for San Francisco families.

San Francisco, California – September 23, 2004 [SolarAccess.com] The San Francisco Public Utilities Commission (SFPUC) approved an agreement with Lennar/BVHP for the redevelopment of the Hunters Point Naval Shipyard, and to include energy efficiency measures and solar electric systems in the construction of 1600 residential housing units. Lennar is the primary building developer selected by the City and County of San Francisco, and will provide assistance to other contractors who require training in constructing with energy efficiency and renewable energy materials. “This agreement demonstrates how clean energy and environmental objectives can be integrated into a major new affordable housing development,” said SFPUC General Manager Patricia E. Martel. “By initiating energy efficient measures with builders, the city can encourage the development of new housing that does not contribute to peak electricity demand in San Francisco.” The agreement between the city and Lennar outlines specific energy efficiency measures for wall and attic insulation, combined water and space heating, better windows, and highly efficient appliances that will be coupled with rooftop solar electric power systems. The collective energy efficiency measures and solar systems should minimize development’s peak demand for electricity in the summer and winter months, and create a significant utility savings for homeowners. High efficiency insulation, and heating and cooling systems recommended for the project are estimated to result in a 48 percent reduction in annual energy costs. The PV array should produce more power than the homes consume during the peak hours of 9 a.m. through 3 p.m. throughout most of the year. Guidelines for the new development were created following a detailed study sponsored by the Building America program through the Seattle Regional Office of the United States Department of Energy. The study analyzed measures that could be incorporated into the housing development that would lower the cost of home ownership. Land from the shipyard is part of a final agreement between Congress and the Navy to govern the transfer of the Hunters Point Naval Shipyard to the City and County of San Francisco. The city and the Navy recently concluded an agreement for the transfer of Parcel A, which is a 78-acre plot where the proposed 1600 new homes will be built. Much of the land that belonged to the shipyard is still being examined for metal contaminants that were used during the Navy’s heyday of shipbuilding.
