AB 802: benchmark your building's energy use


What is Energy Benchmarking?

Energy benchmarking is the practice of tracking a building’s energy usage and using a standard metric to compare the building’s measured energy performance over time and to similar buildings nationwide.

Building owners can access their building’s energy performance data and track it over time and/or compare it to other buildings using the ENERGY STAR® Portfolio Manager®. Portfolio Manager will give your building a score from 1 to 100. The higher the number, the more efficiently your building uses energy. The score will allow you to compare energy usage year-to-year and verify the energy savings from efficiency improvements.

Why Should Building Owners Benchmark their Buildings?

It's the law. As of January 1, 2017, owners of buildings greater than 50,000 square feet. must comply with California’s Assembly Bill 802: Building Energy Use Benchmarking and Public Disclosure Program. The bill is aimed at increasing the availability of building-wide energy use data that will help building owners manage their energy use. For details regarding this law, please visit the California Energy Commission Benchmarking website. If you still have questions please review our FAQs or download the flow chart.

Rising energy costs mean that energy now represents a significant portion of operating budgets for buildings across the nation. Using energy benchmarking has been shown to drive energy efficiency upgrades, reduce energy use, and increase occupancy rates and property values. Building owners that engage in energy benchmarking can also gain ENERGY STAR® recognition by benchmarking their buildings.

Steps to Benchmarking Your Building



Step 1


Step 2

  • Once these completed forms are received, City of Palo Alto Utilities (CPAU) will reach out to you by phone or email to confirm building and account holder information, and identify all associated meters.
  • After confirming all necessary information, CPAU will compile and send the data to you by email within 14 days.

Step 3

Note: You will need to know some basic information like all meter numbers, building square footage, year of construction, number of occupants and how the space is used at this time. If you need help setting up your Portfolio Accounts, let us know.
