Commercial Energy Conservation Ordinance (CECO)

The purpose of CECO is to increase the energy and water efficiency in Berkeley commercial buildings. Compliance with CECO measures saves money, increases the comfort and reduces the amount of greenhouse gas emissions in buildings.

BESO to Replace RECO/CECO:
Effective December 1, 2015, Berkeley's Building Energy Saving Ordinance (BESO) will replace both the Residential and Commercial Energy Conservation Ordinances (RECO and CECO). The transition from RECO/CECO to BESO will occur between October 9, 2015 and December 1, 2015. For more information, see

Effective October 9, 2015

  • RECO and CECO requirements are no longer required at time of building renovation
  • For buildings & houses up for sale between October 9 to December 1, 2015, sellers may choose to either complete RECO/CECO measures (RECO Form A, CECO Form 2) OR complete a BESO Energy Assessment (BESO Compliance Form A)
  • Buildings with a previously filed deferral (RECO Form C or CECO Form 1, Part C) may choose to comply with either the BESO assessment or RECO/CECO measures
  • Deferrals for up to 12 months are only allowed with BESO Time of Sale Deferral Form C

December 1, 2015
