What is Benchmarking?

Benchmarking is the process of measuring your building’s energy consumption and comparing it against past performance and to other similar buildings. Before you take steps to reduce your energy use, it’s helpful to build a complete picture about how your facility uses energy. Currently there are two options for benchmarking your building. 

Aggregated Energy Usage Data 

Currently, the California Energy Commission (CEC) is creating a statewide benchmarking program mandated by Assembly Bill 802 (AB 802) that was signed into law in October 2015.  Beginning January 1, 2017, AB 802 requires that California utilities provide aggregated whole-building energy usage information, subject to certain thresholds set by the number of accounts in commercial and multifamily properties, when requested by building owners. In order to receive your aggregated energy usage data you have to:

- Create your building portfolio in ENERGY STAR® Portfolio Manager

- After your building portfolio is created submit your request to SDG&E to receive your aggregated energy usage data.

Please note that if you're an owner of a commercial, mixed-use and multifamily building(s) larger than 50,000 square feet you will be required to annually report the benchmarking metrics to the CEC who will then make them available to the public.   

Non-Aggregated Energy Usage Data

If you know your building does not meet the threshold set by the number of accounts in commercial and multifamily properties, visit our page that provides instructions on how to receive non-aggregated energy usage data from SDG&E using ENERGY STAR Portfolio Manager.
