BESO Energy Assessors

What are BESO Registered Energy Assessors?
Building Energy Saving Ordinance (BESO), Berkeley Municipal Code 19.81, stipulates that owners of residential and commercial buildings must conduct Energy Assessments and disclose the findings in an Energy Report. These reports inform building owners, as well as potential buyers and renters, of building energy performance and cost-effective opportunities for improvement. Only energy service providers registered with the City of Berkeley (Registered Energy Assessors) will be able to conduct BESO assessments. BESO starts December 1, 2015.
