Portfolio Manager Technical Reference: U.S. National Energy Use Intensity

When you benchmark your building in Portfolio Manager, one of the key metrics you’ll see is energy use intensity, or EUI. Essentially, the EUI expresses a building’s energy use as a function of its size or other characteristics.

For most property types in Portfolio Manager, the EUI is expressed as energy per square foot per year. It’s calculated by dividing the total energy consumed by the building in one year (measured in kBtu or GJ) by the total gross floor area of the building.

The graph below shows some typical EUI values and is based on research EPA conducted on more than 100,000 buildings benchmarking in Portfolio Manager.

A graph that shows typical energy use intensity (EUI) for various building types.

The reference table in Portfolio Manager Technical Reference: U.S. National Energy Use Intensity is designed to help you to compare your property’s energy use to the national median (or mid-point) energy use of similar properties. This document also provides recommended practices to use to benchmark your building portfolio in EPA's ENERGY STAR Portfolio Manager.
