what are standard units for eui
âEnergy Use Intensityâ (EUI) goals are now being incorporated into architectural and engineering agreements for all our major building projects. Standard EUI units are expressed in terms of BTUs per square foot per year. Each new building and major renovation on campus has a unique EUI, depending on how the building will be used. On average laboratories use 5-10 times more energy than dormitories on a per square foot basis.
