ZERO Code for California
The ZERO Code for California (ZERO Codeca) is a building energy standard developed by Architecture 2030 that applies to new commercial, institutional, high-rise residential, and hotel/motel buildings.
Codeca proposes using a TDV-weighted source energy metric (current code uses TDV only) as the building performance measure, which promises to more accurately reflect carbon-intensity.
Local jurisdictions may wish to consider developing a reach code based on Codeca.
