 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 from all buildings over 50,000 sqft annually. 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 efficient. 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.   

If you are new to benchmarking, please complete steps 1-4 below. If you have submitted benchmarks in previous years, proceed to step 3 and 4.

Step 1:
Set-up your building in ENERGY STAR Portfolio Manager
Step 2:
Gather and input your energy use data 

  • Manually input data
  • Set-up PG&E’s Automatic Data Transfer

Step 3: Confirm your data is complete and accurate
Step 4: Submit the annual energy benchmark


Step 1. Set-up your building in ENERGY STAR Portfolio Manager

ENERGY STAR Portfolio Manager is a free online tool created by the U.S. Environmental Protection Agency to help building owners track their energy, water and waste usage. Annual Benchmarks must be submitted through this tool. 

If you’re new to benchmarking and ENERGY STAR Portfolio Manager you can use the following BESO Guide on How to Set-up Your Building on Portfolio Manager

Additional resources on getting started with Portfolio Manager.  


Step 2. Gather and input your energy use data

You will need to input your energy use data for the required benchmarking year into ENERGY STAR Portfolio manager. If you have access to the monthly energy bills for each of the electric and gas meters for your building you can input these directly into Portfolio Manager.

If your building has multiple tenant accounts and needs aggregated whole-building data, or if you want to have PG&E automatically transfer energy data into your Portfolio Manager account, you will need to use PG&E's Benchmarking Portal. 

How to set up PG&E’s automatic data transfer:

  1. Set up your account and building on PG&E’s Building Benchmarking Portal
  2. Select your Energy Meters and Initiate the data transfer to Portfolio Manager    

Step 3: Confirm your data is complete and accurate

Building owners are required to submit accurate and complete benchmark reports to be in compliance. Benchmarks submitted with errors may inaccurately represent your buildings energy use and may not be approved.

Please review the energy data and building characteristics for your building and run the data quality checker. Use the following guide on How to Run the ENERGY STAR Data Quality Checker. If your meter is connected to PG&E's data transfer service and there are overlapping monthly entries or some entries are missing, please use the following guide on How to Correct Energy Data Issues.

**Due to the impact of COVID-19, Commercial buildings may need to update the Weekly Operating Hours and Number of Workers on Main Shift to ensure the ENERGY STAR Score is accurate for the 2020 reporting year. Please see Step 2 of the following guide for information on how to update your building's property use detail. 

Step 4: Report benchmarking data to the City

Once the energy use data has been inputted for the full calendar year into ENERGY STAR Portfolio Manager you can report the 2020 Benchmark through this  2020 BESO Benchmarking Data Submission link

For detailed instructions use the following guide on How to Submit the 2020 Benchmark
