2022 ZERO Code for California

I'm proud to annouce that the next version of Architecture 2030's ZERO Code for California is published on their website. Click here. I was the primary author of this document, as a Senior Fellow with Architecture 2030. We are now working with AIA California to promote its adoption by local governments. It is also being proposed as an addition to the CalGreen, the green building code for California. The code builds on top of the California Energy Commission's tough energy standards and requires that all buidlings have a minimum amount of on-site solar; the rest is purchased through 100% renewable energy programs offered by the state's investor owned utilities or community choice aggregators. Since the electricity is clean, gas burning appliances are prohibited.
