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|

Customers that complete the audit and reduce EUI will receive a minimum base incentive of $0.10/ft2.
Buildings under 200,000 ft2 must audit the entire building.
Buildings over 200,000 ft2 may complete an audit of the entire building or a partial building audit, provided the audited portion of the building is on a separate utility meter.
Building baseline EUI will be determined using 12-24 months of recent utility bills and gross square footage.
Customers will receive an additional $0.01/ft2 for every 1% EUI reduction over 5%.
Incentives are capped at a 15% EUI reduction or $0.20/ft2.
Incentives are capped at 75% of the total cost with a maximum incentive of $100,000 per project.
