Another California community college district undertaking a significant effort in the design and construction of energy-efficient buildings and associated renewable energy supply is the Los An- geles Community College District (LACCD), which consists of nine colleges at locations around the city of Los Angeles and serves 135,000 students.
Background
In 2008, the California legislature passed and then-governor Arnold Schwarzenegger signed SB1, known as “The Million Solar Roofs” bill. It was estimated at the time that the provisions in the bill would stimulate 3,000 MW of new solar electric power, the equivalent of approximately 6 “peak power plants”. The incentives for installing solar energy systems were soon incorporated into various facility plans, community colleges included, and sparked an interest in the construc- tion of grid-neutral and zero-net-energy (ZNE) buildings.
Meanwhile, voters in Los Angeles had passed a series of bond measures over the previous sev- en years totaling $5.7 billion for improvements to community college campuses, which included energy efficiency upgrades. With the timing of the bond program, SB1 funds and the commit- ment of the State of California to move toward less dependence on carbon-based energy, Los Angeles Community College District (LACCD) initiated a plan to build these facilities to achieve ZNE performance.
This idea was first tried out with five building projects in early 2009, one of which was the Harbor College Science Building. The District issued an RFP to three pre-qualified design-build teams, stating in part,
“This project shall be built in a manner that maximizes all possible sustainable attri- butes including, but not limited to, state-of-the-art building design, mechanical design, and material selection, and building integrated renewable energy-generation systems to achieve zero-energy consumption and a carbon-neutral profile upon completion.”
