To generate a building’s estimated energy consumption, and the renewable energy required to meet the Zero Code for California, first elect the pathway for meeting 2019 California Building Energy Efficiency Standards (BEES) – prescriptive or performance – and then enter information about your building and any on-site solar PV system(s). Click Generate Results to view the the Estimated Building Energy Consumption and/or off-site Renewable Energy Requirements.
Note: The Zero Code for California Energy Calculator currently includes weather and solar files for all 16 California climate zones.
The Zero Code for California energy calculator will be updated to reflect the 2022 California Building Energy Efficiency Standards (BEES) once analysis of its performance is published by the California Energy Commission.
The ZERO Code is an Architecture 2030 initiative.
Architecture 2030, in offering the ZERO Code, accepts no responsibility or liability for the accuracy of the inputs, assumptions, default values, and results estimated by the ZERO Code Energy Calculator, or for the design and performance of buildings utilizing the ZERO Code.
If you have questions about the ZERO Code, or if you are a legal jurisdiction that would like support in adopting the ZERO Code, please contact info@architecture2030.org.
