Building Energy Saving Ordinance (BESO)

BESO to replace the Residential and Commercial Energy Conservation Ordinances (RECO/CECO) 

Current Status BESO was adopted into law on unanimous consent on March 10, 2015. The ordinance will require energy assessments at time of sale for medium, small, and single family buildings, as well phased-in by building size and year for all buildings, with the exception of single family homes (1 to 4 units). This energy and water efficiency information will provide Berkeley property owners and potential buyers with an efficiency road map tailored for their building and link them to valuable incentives and resources provided through utility rate-payer efficiency funds. The goal of BESO is to accelerate greenhouse gas emissions reductions to help us meet our Climate Action goals, save money on utility bills, and improve occupant health and comfort.

BESO Energy Assessment Requirements When buildings are sold or due based on phase in schedule (whichever comes first), they are required to:

  1. Demonstrate the building is a high performance building; OR
  2. Conduct an energy assessment and disclose report and score to potential buyers and City

The Role of RECO and CECO Berkeley's RECO and CECO laws require buildings that are transferred or remodeled to install water and energy saving measures in order to reduce the electricity and natural gas usage and curb greenhouse gas emissions. RECO and CECO, enacted in 1987 and 1994 respectively, have played an important role in improving the energy efficiency of the existing building stock and saving the community money on utility bills while reducing greenhouse gas emissions. BESO will continue to ensure that property owners understand how to make Berkeley's buildings as energy and water efficient as possible.
