Retrocommissioning Program

RCx — A Fast-track Building Retrocommissioning Program

The RCx Program is your fast track to energy savings and is now being offered in partnership with The Southern California Gas Company.

If you are a customer of the LADWP and own a business, or represent a non-residential customer, the RCx program can help reduce your electricity and gas usage as well as reduce the cost of building operations. By implementing one or more of the program’s 13 retrocommissioning (RCx) measures, you can save on energy costs and improve building operations. So, if you are a non-residential LADWP customer, let us put our energy to work for you with this exciting program.

This is not your typical RCx that requires days of data collection, complex calculations for energy-saving measures, assessment reports, and in-depth system analysis. Instead, this is a simplified program that requires minimal system data and uses “prescribed” savings calculations, which makes the process much easier. It also means you’re on your way to savings much faster.

The Bottom Line

The first step is to survey your building to see if you qualify for any of the 13 measures offered by the program. You can perform the survey with your own staff, hire a retrocommissioning provider, or oversee the work of contractors you hire. You can easily find out whether you qualify and how much the savings and incentive will be. Then fill out a couple of forms or the spreadsheet and you are on your way.

What is commissioning?

The U.S. Department of Energy (DOE) defines commissioning as the "… process of ensuring that systems are designed, installed, functionally tested, and capable of being operated and maintained according to the owner's operational needs." Commissioning is a very methodical process that verifies whether all of a building’s equipment is operating as smoothly and efficiently as possible. The intent of commissioning is to insure proper building performance.

What is retrocommissioning?

Retrocommissioning (RCx) is a type of commissioning, and is often referred to as commissioning an existing building. According to the DOE, retrocommissioning is "the same systematic process applied to existing buildings that have never been commissioned to ensure that their systems can be operated and maintained according to the owner's needs."

The RCx Program Benefits

  • Cash incentive paying from $0.10 to $0.15 per kilowatt hour (kWh) saved (annualized)
  • Cash incentive paying $1.00 per therm saved (annualized)
  • Lower energy bills
  • A more productive facility
  • More efficient building operations
  • Longer equipment life
  • A building assessment by qualified engineering professionals
  • Support throughout the process

What are the RCx Measures?

The RCx program has 13 common controls- and schedule-based commercial building optimization measures.

HVAC airside measures include:

  • Reduce supply fan operating schedule
  • Adjust airside economizers
  • Adjust zone temperature deadband
  • Add supply air temperature setpoint reset strategy
  • Reduce supply duct static pressure setpoint
  • Add supply duct static pressure setpoint reset strategy
  • Add/restore supply fan VFD (Requires malfunctioning inlet guide vanes, or malfunctioning VFDs)

HVAC waterside measures include:

  • Add/optimize boiler lockout
  • Add chilled water supply temperature setpoint reset strategy
  • Add condenser water supply temperature setpoint reset strategy
  • Restore chilled water pump VFD

Lighting measures are:

  • Reduce lighting operating schedule
  • Restore lighting occupancy sensors


All LADWP non-residential electric customers in good standing are eligible to participate in this program as long as the building qualifies for one or more of the program’s 13 measures. The suggested minimum building size is 50,000 square feet, and facilities should be one of the recommended building types. Many measures benefit from a centralized building automation system, but it is not necessarily a requirement.

How It Works

You enroll in the RCx program by filling out an Application Form and providing minimal information about your building. You also provide limited specific data for the RCx measures you think you can apply at your building.

The application is in Interactive Adobe Acrobat PDF file format. Download the PDF file to your personal computer (PC). Once the file is saved and then opened on your PC, you may fill out the RCx Application, print it, sign it, and mail it to the address on the application.

The measure-specific data can be supplied by filling out hard copy forms and submitting those, or by filling in the Building Optimization Analysis (BOA) Tool.

The BOA Tool is an Excel spreadsheet-based program used to calculate energy savings for certain RCx measures. With a minimum of data that you provide, this tool calculates energy and demand savings and incentives amounts using prescribed savings. Visit the California Commissioning Collaborative website to download the BOA Tool at

Please send the completed electronic copy of the spreadsheets via e-mail to the RCx Program Staff at

The next step involves a Program Verification Engineer conducting a baseline inspection and confirming the data, which results in an Authorization to Proceed and the associated reservation of funds. After the measures are installed or implemented, the engineering staff will review the installation (or EMS software changes). Repair work can be done in-house or by a service contractor, who can be paid directly by the program. LADWP program assistance is available.

Upon successful completion of the installation inspection, the LADWP will process the incentive payment. Incentive checks are processed within 4 to 6 weeks of final approval.

It's that easy!
