California Public Utilities Commission has recently outlined requirements for Zero Net Energy Homes, the first state in the nation to create this mandate. As spelled out in the California Energy Efficiency Strategic Plan, the state has ambitious goals for the development of zero net energy buildings. The standards, which begin to take effect on January 1, 2020, will help with both energy savings and reduction of the carbon footprint of California's homes and buildings—the second-largest source of greenhouse gas emissions in the state.

These new measures include:

  • All new residential construction will be zero net energy (ZNE) by 2020.
  • All new commercial construction will be ZNE by 2030
  • 50% of commercial buildings will be retrofit to ZNE by 2030
  • 50% of new major renovations of state buildings will be ZNE by 2025, and 100% by 2025
