How new energy codes are affecting greenhouse growers
Added on 07 October 2022
Changes to the California Energy Code (Title 24, Part 6) for Controlled Environment Horticulture were proposed in 2020, adopted in 2021, and will go into effect at the beginning of 2023. Included in the new 2022 Energy Code are requirements for greenhouses and indoor cultivation facilities to meet minimum standards for horticultural lighting efficacy, dehumidification system efficiency, and greenhouse envelope thermal performance. The requirements affect facilities growing any crop. Newly constructed greenhouses, greenhouses being converted from unconditioned to conditioned, and additions to conditioned greenhouses with permits pulled after Jan. 1, 2023, may need to meet minimum efficiency requirements. Existing buildings are not affected unless a facility alteration triggers requirements in the Energy Code. California growers can use the Energy Code Ace website to access helpful resources for compliance with the California Energy Code.
