ENERGY STAR – Learning

How do I know how my facility is performing?

Understanding the energy use of a building or plant is important–just as it’s useful to know the estimated miles per gallon for your automobile. ENERGY STAR provides free tools and resources to help you measure the energy use of your facility and to compare your facility with other, similar facilities. For many types of commercial buildings, you can enter energy information into EPA’s free online tool, Portfolio Manager, and it will calculate a score for your building on a scale of 1-100. Buildings that score a 75 or greater may qualify for the ENERGY STAR. In the industrial sector, plants awarded the ENERGY STAR must score within the top 25 percent of energy efficiency within their industry nationwide, based on a plant energy performance indicator (EPI).
