Energy Conservation Ordinances

Conserving energy in existing buildings is an important goal for the City of Berkeley. It helps save money and reduces green house gas emissions.

RECO/CECO Transition to BESO: The Building Energy Saving Ordinance (BESO) will replace RECO/CECO starting on December 1, 2015 (starting on October 9, sellers have the choice of complying with RECO or BESO). For more information, see:

  • RECO (Residential Energy Conservation Ordinance)
