Zero Net Energy will be the standard for new construction by 2020

Green energy construction and retrofits

We are already there and beyond!

The California Public Utilities Commission (CPUC) adopted the aspirational goals that all new residential construction in California will be zero net energy by 2020, and all new commercial construction in California will be zero net energy by 2030.

The Danielsen Construction team has been practicing high-efficiency techniques for the last 10 years. We are already qualified to meet the ZNE standards for both retrofits and new construction.

What is part of ZNE?

Zero net energy means that the building produces at least as much energy as it consumes.

How do we achieve ZNE?

  • Assessment, Design, and Precise Execution
  • Air sealing, Duct engineering, Insulation
  • Properly sized and integrated HVAC system
  • LED Lighting
  • Solar Energy & Storage
