New PUC building is 'greenest' in country


The building is located at Golden Gate Ave. and Polk Street and is the new home of the San Francisco Public Utilities Commission. The 13-story structure also harnesses wind energy and reuses all of its wastewater.

"We actually have a tidal basin that we have created here in the building and outside the building that will allow the water to really go through a tidal kind of system of ebbs and flows to clean the water," SFPUC General Manager Ed Harrington said.

The lights are controlled by a smart grid that dims lights near sunny windows.

The building will also force San Francisco Public Utilities Commission employees to go green on the way to work because there are only four parking spaces available for 900 employees.
