Berkeley’s Building Energy Saving Ordinance (BESO) requires building owners and homeowners to complete and publicly report comprehensive energy assessments to uncover energy savings opportunities.
BESO compliance is required on a phased-in schedule for all buildings except houses (1-4 units). The timing, frequency and specific type of energy assessment required depends on the type and size of building. The schedule is shown below:
|Building Size||Due Date||Report Required||Frequency|
|Buildings 50,000 sf or more||7/1/2018||Energy Assessment|
|Buildings 25,000-49,000 sf||7/1/2019||Energy Assessment|
|Buildings 15,000-24,999 sf||7/1/2020||Energy Assessment||10 years|
|Buildings 5,000-14,999 sf||7/1/2021||Energy Assessment||10 years|
|Buildings less than 5000 sf||7/1/2022||Energy Assessment||10 years|
The Energy Assessment is also due at the time of sale of a house or building under 25,000 square feet.
Filing fees range from $79 to $250 based on building size, see BESO Application for details.
Benchmark Report means an ENERGY STAR Portfolio Manager Benchmark Report, generated by the EPA Portfolio Manager online tool.
An Energy Assessment is a report prepared by an architect or professional engineer that identifies opportunities for water and energy efficiency in a building and available incentives and financing options. It includes an ENERGY STAR score generated by Portfolio Manager.
These reports are to be made available to existing lessees, prospective lessees and buyers prior to execution of a lease or contract of sale.
Certain exceptions, deferrals and extensions may apply. See Section 19.81.090 Exceptions, Deferrals and Extensions at: https://www.cityofberkeley.info/uploadedFiles/Planning_and_Development/Level_3_-_Energy_and_Sustainable_Development/BESOordinanceUpdated_20170329.pdf
