GREENSPAN: A RENEWABLE ENERGY PRODUCTION PROPOSAL FOR THE EASTER SPAN OF THE SAN FRANCISCO & OAKLAND BAY BRIDGE

San Francisco - Oakland, CA

Greenspan consists of a renewable energy production proposal for the eastern span of the San Francisco Bay Bridge. The project synthesizes bridge construction, roadway, and safety systems with new sustainable energy technologies, capitalizing on a unique opportunity to create a hybridized form of infrastructure. Greenspan strikes a balance between energy consumption and sustainable energy production.

Energy Production
Bridge lighting stanchions support the pedestrian and bicycle lanes on the south side of the viaduct as well as a steel-tensile fabric embedded with photovoltaic panels and micro wind turbines. The canopy takes full advantage of sun exposure & prevailing winds, while sheltering the underway of pedestrians and bikers. Providing 9 acres of surface, the integrated system produces over 3 million kWh of electricity annually.

California law requires 20% of its energy shall be produced from renewable sources by 2017.  Greenspan presupposes a tectonic vision that celebrates environmental responsibility, civic awareness and energy independence.
