Save 16 percent on energy bills* and get a payback within one year.

Retrocommissioning (RCx) is the process of improving the performance and energy efficiency of building systems, equipment, and operations as a whole. The Focus on Energy RCx offering identifies lower cost measures involving adjustments, recalibrations, and process changes to provide quick energy savings paybacks. Through RCx, you can manage energy use more effectively, improve indoor air quality and building occupant comfort, and discover maintenance needs before they become costly repairs. 


New offering in 2021!

Customers that complete the audit and reduce EUI will receive a minimum base incentive of $0.10 per square foot. Additional incentives up to $0.10 per square foot are available for achieving higher than a 5% reduction in Energy Use Intensity.

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

Market Sector Property Type Median Site EUI (kBtu/ft2)
Education College/University 84.3
Education K-12 School 48.5
Food sales and service Supermarket/Grocery Store 196

Incentive Structure

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.
