What comes to mind when you hear the phrase "green building?" Sleek new structures with skins of advanced glass and recycled steel that blend into the landscape, facades and roofs draped in a combination of daylight-harvesting windows, wildlife habitat, and photovoltaics? New construction affords the flexibility to build contemporary masterpieces, like the California Academy of Sciences, which will receive its LEED Platinum certification this morning in San Francisco. The museum will be the largest and most visited LEED Platinum building in the world.
The Academy of Sciences is a breathtaking example of our city and our citizens' efforts to address the fact that roughly half of all greenhouse gas emissions in San Francisco are attributable to our buildings. In August of 2008, I signed a groundbreaking green building ordinance that created the most stringent green building requirements in the nation. This was a big step in the right direction, requiring that all new buildings be subject to an unprecedented level of LEED and green building certifications. However, a comprehensive recipe for our environmental and economic sustainability requires solutions to the challenges posed by existing buildings.
