Energy Benchmarking

What is benchmarking?

Energy benchmarking is tracking a building’s energy and water use, then using a standard metric to compare the building’s performance against past performance and to its peers nationwide. These comparisons have been shown to drive energy efficiency upgrades and increase occupancy rates and property values. Rising energy costs mean that energy now represents a significant portion of operating budgets for buildings across the nation.


The purpose of the program is to help raise awareness and encourage building owners find ways to increase energy efficiency and reduce consumption of energy in existing nonresidential buildings across the state of California.

Getting started

The Environmental Protection Agency (EPA) has created an online benchmarking tool called the ENERGY STAR® Portfolio Manager. This is an interactive energy management tool that allows you to track and assess energy and water consumption for your building or across your entire portfolio of buildings in a secure online environment. The EPA has developed a Benchmarking Starter Kit to help you get started quickly. EPA offers free webinars to help you through the process. For questions on Portfolio Manager, refer to ENERGY STAR's online Help and FAQ or contact
