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.
How do I get started?
Choose and find an approved RCx Service Provider (RSP) Trade Ally
Work with your RSP to complete the RCx Enrollment Application [PDF] (pg. 3-4)
Complete the RCx audit within six months of approved enrollment.
RSP submits the estimated savings workbook, audit report and audit invoice to Focus on Energy. See page 4 for submittal information.
Focus on Energy reviews and approves the workbook and issues an Incentive Agreement to the customer.
Chosen RCx measures are implemented within six months of audit approval.
RSP resubmits the workbook with savings verification and implementation invoice and invoices from third-party contractors.
Focus on Energy reviews and approves the final workbook and issues a Project Completion Notice to the customer. Incentive will be sent upon receiving signed project completion notice from the customer.
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) |
| Education | College/University | 84.3 |
| Education | K-12 School | 48.5 |
| Food sales and service | Supermarket/Grocery Store | 196 |
| Healthcare | Hospital (general medical and surgical) | 234.3 |
| Office | Office | 52.9 |
| Warehouse/Storage | Distribution Center | 22.7 |

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. Customers are required to invest at least $0.10/ft2 in the project (audit plus implementation cost). |
