 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. Half of all green house gas emissions in Berkeley come from electricity and natural gas usage in existing homes and businesses. Find out below about Berkeley's Energy Conservation Ordinances and the energy efficiency measures.

 RECO (Residential Energy Conservation Ordinance)

CECO (Commercial Energy Conservation Ordinance) 

RECO/CECO Update On September 10, 2013, City Council adopted a resolution directing staff to initiate a public process to update the City's existing Residential Energy Conservation Ordinance (RECO) and Commercial Energy Conservation Ordinance (CECO) laws. BESO was adopted into law on unanimous consent on March 10, 2015 and will replace RECO/CECO starting on December 1, 2015 (starting on October 9, sellers have the choice of complying with RECO or BESO).
