Often building owners and managers do not have information on their building’s energy use, making energy management nearly impossible. Benchmarking is the practice of tracking a building’s energy use over time and comparing changes to a baseline year or to other similar type buildings.

A free and easy-to-use online benchmarking tool, EPA’s ENERGY STAR® Portfolio Manager, can compare a single building’s performance with other similarly operating buildings, and calculate a 1-100 score to inform building owners and managers about their building’s performance relative to others in the marketplace. Any building or portfolio of buildings can use the tool.

By benchmarking a building’s energy use, building owners and managers have valuable data, which can be used to lower utility bills. Specifically, if a benchmarked building is not performing as well as expected, it could mean that energy is being wasted in the system.  This means that finding where that energy waste is occurring and eliminating it though an energy audit, retrocommissioning, or upgrades could create significant savings for a building owner over time.
