Solar Photovoltaic Array San Francisco International Airport San Francisco, CA

Interactive Resources was retained by BASS Electric to provide structural engineering services for the 500 kW solar array at Terminal 3 of San Francisco International Airport. By addressing both generation and consumption, the airport was able to combine the short term payback of energy efficiency upgrades with the long term need for renewable, locally generated electricity. This 500 kW solar array on the roof of Terminal 3 is part of a City of San Francisco green initiative to get 20% of power from renewable resources by the year 2012. Mayor Gavin Newsom presided over the grand opening in August 2007.

The power generated from the photovoltaic array covers approximately 15% of the Terminal’s annual electric consumption and will avoid about 7,200 tons of Carbon Dioxide emissions over a 30 year period.

The energy efficiency solution included upgrading 4,239 lighting  fixtures and resulted in:

Reduced daily demand by 395 kW

Annual energy savings of 3,460,261 kWh

$278,600 annual energy cost savings

This state-of-the-art 500 kW photovoltaic generation system consists of:

Approximately 3,000 SunTech modules on a sunLink rack system

Curved array maintaining unique aesthetic of building

Easy access to support roof structure without relocating solar array
