According to the Union-Tribune, a $432 million project is making its way to San Diego City Council for consideration as the new San Diego City Hall. Although still in early stages, developer Gerding Edlen indicates that the design is beyond LEED Platinum, and according to some, it could be one of the greenest buildings on the West Coast if built. The 23-story building, with a design that kind of resembles a large sail, has some of the following green elements:
- Solar thermal panels that offset about 75% of total hot water demand;
- Solar PV panels that provide roughly 8% of total energy use;
- Natural light, efficient lights, and smart controls that reduce energy consumed by 9%;
- Small wind turbines that generate supplemental electricity;
- Waste water that's treated on-site for reuse and to be exported elsewhere;
- A green roof to capture and filter rainwater; and
- An efficient chilled water system that cools the building.
The Zimmer Gunsul Frasca Architects design is handsome and innovative, and if San Diego decides to build something, they'd be in good hands with Gerding Edlen. The company has considerable experience with LEED projects, as well as a cutting edge Living Building Challenge project called the Oregon Sustainability Center. In any event, only time will tell as the new green San Diego City Hall still has a number of details to be determined.
