Renewable and Zero Net Energy

The California Public Utilities Commission adopted a “Big Bold Initiative” that decreed that all new residential buildings in California will be zero net energy by 2020, and all new commercial buildings will be zero net energy by 2030 (California Energy Efficiency Strategic Plan, January 2011). DEG brings years of experience in technology evaluation and energy modeling, engineering expertise in building and mechanical systems, and lessons learned from previous projects to develop optimal zero net energy designs for individual homes as well as communities.

  • In 2000, DEG was selected as one of four teams under the DOE’s Zero Energy Homes Program and worked with Centex Homes to build one of the first homes in the program.
  • In 2005, DEG was part of the SunPower team involved in the California Zero Energy New Homes Program, funded by the California Energy Commission. The goal of the program was to evaluate the market potential of moving residential new construction towards zero energy goals by 2013, with the short term goals in 2005 to reach 70 percent annual electric bill savings, and maximum peak of 1 kW energy expenditure.
  • We worked with EDAW/AECOM to help develop models for three zero carbon communities in California, Arizona, and North Carolina.
  • DEG is currently under contract with both PG&E and SCE to provide analysis support, design assistance and technology evaluations for their Zero Net Energy Pilot Programs and PG&E’s Zero Net Energy program.
  • DEG has a key role in the building design optimization and evaluation for the University of California, Davis West Village zero net energy community. We continue to consult with both UC Davis and the private development partners through the multi-year construction process.
  • DEG collaborated with One Sky Homes to design the first certified zero net energy home in California.
