Is Net-Zero Campus Construction Possible?
Wendell BraseAssociate Chancellor for Sustainability
California's Pathto Zero Net Energy
In 2007, the California Public Utilities Commission (CPUC) adopted the new goals to have all residential construction in California be zero net energy by 2020, and all new commercial construction in California be zero net energy by 2030.

Next Steps to Radically Improve Building Efficiency?
• Fatter buildings• Smaller windows / less glass• No more “glass box” architecture• Move glass to the north side of building• Electro‐chromic “smart” glazing systems
Next Steps to Radically Improve Building Efficiency?
• More precise ways to move energy• More precise ways to control energy• Desiccant dehumidification• Chilled beams• More district heating and cooling
Next Steps to Radically Improve Building Efficiency?
• Whole roof solar canopies• Solar panel canopies• Electric storage• Chilled water storage
