From the Honest Buildings blog post:

In October 2011, the University of California at Davis unveiled a new mixed-use campus housing center called West Village. The $300 million project is one of the most innovative and ambitious of its kind. What makes it so special? For one thing, it sets a precedent with its scale: 130 acres, including 662 apartments and 343 single-family houses, 42,500 square feet of commercial space, a recreation center and village square. For another, it's ingeniously designed to not only generate as much energy as it uses (with a 4 megawatt solar panel system) but to make sure that residents don't need a lot of energy in the first place (for example, wooden slats keep sunlight from heating rooms too warm, creating the need for air conditioning).

Other features include a waste-to-energy bio-digester – an invention patented by UC Davis engineer that will be in full use next year. It will convert the village’s garbage and waste, also referred to as “feed stock,” into energy. (Source:  KQED News).
