ZNE – Zero Net Energy

Zero Net Energy (ZNE, also called Zero Energy or Net Zero Energy) buildings produce as much energy as they consume. Starting in 2020, ZNE building techniques will be mandatory for residential housing.

How would you like to leave the temperature in your house at one setting and never worry about energy bills again? A ZNE building is self-sufficient, so it produces as much, or more, electricity than it uses.

We take the “whole house approach” to make the building truly energy efficient. This means that we look at each task, beforehand, to plan the building process, while maintaining a controlled budget.

Upgrading your home means upgrading your life!

Does your house meet the new standard?

Zero Net Energy will be a requirement in 2020...

…for all new residential construction in California, and all new commercial construction by 2030. This has been decided by the California Public Utilities Commission (CPUC).

We are already meeting these requirements to outperform the standards of today.

The U.S. Department of Energy’s (DOE) Builders Challenge program has recognized hundreds of leading builders for their achievements in energy efficiency. We are proud to be partner of this program!
