The weather normalized EUI uses average temperatures over time to minimize the impact of outlying temperature changes year to year in energy use calculations.

• Calculating EUI: EUI (Energy Use Intensity) is the building’s total energy use for one year
• Divided by gross square footage. This information allows buildings with different sizes and
• Similar uses to be compared. To learn how to calculate your EUI, visit this resource: https://www.energystar.gov/buildings/benchmark/understandmetrics/what-eui
