The Zero Code project combines a model building energy standard with a policy approach to require the adoption of renewable energy to projects to offset designed energy use to achieve zero net energy in buildings. A version of the Zero Code has been adapted to California in compliance 2019 California Building Energy Efficiency Standards.
The Zero Code provides code-adaptable language that defines the energy efficiency measures and on-site renewable energy production and/or off-site renewable energy procurement to support the construction of zero carbon buildings.
