Software: Energy Use Intensity

Energy Use Intensity

Energy Use Intensity (EUI) is a useful metric to monitor long-term energy efficiency trends for a building. ENERGY STAR defines EUI as “a unit of measurement that describes a building’s energy use. EUI represents the energy consumed by a building relative to its size. A building’s EUI is calculated by taking the total energy consumed in one year (measured in kBtu) and dividing it by the total floor space of the building.”

EnergyCAP uses weather-normalized energy use to calculate annualized EUI and displays it on a trend chart. EnergyCAP can also roll up EUI values at every level of the organizational hierarchy. This functionality provides a valuable picture of long-term energy efficiency trends for each department, division, region, and business unit, as well as for the entire organization.
