Zero net energy (ZNE) is becoming the new standard for California homes.

A ZNE home is energy neutral, meaning it produces as much energy as it consumes in a year. This is reached by first achieving high energy efficiency, then adding a renewable energy source like solar or wind.

California’s goal is for 50% of existing homes to be retrofitted to ZNE by 2030. To achieve this, strategically planned home performance upgrades will need to occur. ZNE can be achieved through the combination of upgrades, including but not limited to:

  • Air sealing and insulation
  • Efficient technologies including HVAC, lighting and controls
  • Renewable energy generators, like solar or wind

Benefits of ZNE

  • Provides the comfort, technology, and savings homeowners need.
  • Increases utility bill savings and provides a hedge against future increases in electricity costs.
  • Better home performance increases its value.
