BESO Ordinance Requirement (Bldgs <25,000 ft2):

The Building Energy Saving Ordinance (BESO) requires annual building energy benchmarking through Energy Star Portfolio Manager as well as an energy assessment for all large buildings in Berkeley, phased-in by size. For all BESO requirements, please visit the BESO Large Building Requirements page.

AB802 California State Law Benchmarking Requirement (Bldgs <50,000 ft2)

AB802 requires benchmarking data to be submitted to the California Energy Commission by June 1st, 2018 for all buildings over 50,000 ft2 with no residential accounts. By complying with the BESO City ordinance, you will also satisfy the state requirement, as the City will submit your data in approved format to the State. 

Why Benchmark?
Benchmarking is the first step towards making buildings more energy efficifient. Through tracking building energy performance, you can identify ways to lower energy use and associated costs.


  • Inform investment decisions
  • Identify opportunities to lower energy costs  
  • Buildings with a verified benchmark score of 80 or above are exempt from assessment requirements  
  • Help Berkeley meet our community climate action goals  



Instructions for using the EPA's Portfolio Manager to comply with the City of Berkeley's BESO benchmarking requirement for buildings greater than 25,000 square feet.  

Step 1: Register Your Building

Step 1B. Determine if you will need to aggregate your whole-building data.)
If your building has multiple tenant accounts and needs aggregated whole-building data, you will need to use PG&E's Benchmarking Portal. Reference guides below to understand additional processes required to benchmark.
