The Building Energy Saving Ordinance (BESO) was amended by the Berkeley City Council on December 15th, 2020 and the name of Chapter 19.81 of the Berkeley Municipal Code has been updated to the Berkeley Emissions Saving Ordinance in addition to several updates, including updates to the BESO requirements. See the webpage below for additional details on the changes to BESO.

Energy use in our homes and commercial buildings is the second leading contributor of greenhouse gases in the City of Berkeley making up 38% of our overall greenhouse gas emissions with 31% of Berkeley's citywide emissions coming from natural gas, according to Berkeley's latest green house gas inventory.

BESO requires building owners and homeowners to complete and publicly report comprehensive energy assessments to uncover energy and GHG emissions saving opportunities. The assessments are conducted by registered energy assessors (for Commercial, Multifamily & Mixed Use or Houses [1-4 unit residential buildings]) who provide tailored recommendations on how to save energy, eliminate fossil fuels and link building owners to incentive programs for energy efficiency and electrification upgrades (for residential see bayrenresidential.org; for multifamily see bayareamultifamily.org). Energy efficiency improvements and electrification recommendations are voluntary and encouraged. BESO is required prior to sale of a house or whole building under 25,000 square feet, and on a 5-year reoccurring cycle for large multifamily and commercial buildings.
