When the Golden Gate Valley Library of San Francisco was renovating and updating to accommodate the Americans with Disabilities Act, the organization figured it was also time to green up the space and achieve LEED Silver for Commercial Interiors status. The building has since reached LEED Gold status.
Tom Eliot Fisch and Paulett Taggart Architects worked together on the project, performing a number of eco-friendly upgrades. Rather than adding a ramp or addition to the street-facing exterior, the team used a courtyard on the side of the building for a contemporary style, wheelchair-accessible glass and aluminum elevator.
The team also replaced windows with the most access to sunlight with high-performance glazing to reduce solar heat gain, and restored and cleaned the rest for added efficiency while maintaining the historical structure. They also added in a high efficiency mechanical system and energy efficient lighting to reduce energy use while improving comfort for visitors. Low flow faucets reduce water use, and low VOC paints and finishes improve air quality. Existing furniture was restored, and a photovoltaic rooftop system meets 25% of the energy demand.
To top it all off there is also an improved bike parking area, a new teen area, and improved accessibility for visitors with disabilities. The reservations, completed in 2011, have received several awards for its sustainable preservation of the building, originally built in 1918.
