Do you know your Energy Use Intensity (EUI)?
ENERGY STAR Portfolio Manager® expresses EUI as energy per square foot per year. Calculate EUI by dividing the total energy consumed by the building in one year (measured in kBtu) by the facility's gross square footage.
Below is a table of Median site EUIs for common property types. A full list can be found at energystar.gov
|Market Sector||Property Type||Median Site EUI (kBtu/ft2)|
|Food sales and service||Supermarket/Grocery Store||196|
|Healthcare||Hospital (general medical and surgical)||234.3|
