Retrocommissioning Express (RCx) for Commercial Buildings

Take the fast track to energy savings!

Reduce your energy bills and the cost of building operations with RCx Express. This no-cost/low-cost program is available to non-residential customers in the shared service areas of SoCalGas® and the Los Angeles Department of Water and Power (LADWP). It requires minimal system data and uses pre-calculated savings, helping you save much faster than standard retrocommissioning programs.

RCx Program Benefits

  • Cash incentives paying $1 per therm saved and $0.08 per kilowatt hour (kWh) saved (annualized)
  • Reduced electricity and gas bills by up to 15 percent


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. In addition, customers who receive service from both SoCalGas and LADWP are eligible to receive financial incentives on both gas and electric measures. The suggested (but not required) minimum building size is 50,000 square feet, and many measures benefit from a centralized building automation system.

The BOA tool is an Excel spreadsheet-based program used to calculate energy savings for certain RCx measures. Visit the California Commissioning Collaborative website to download the BOA Tool.

3. After the measure specific data has been submitted, a Program Verification Engineer will conduct a baseline inspection. Confirmation of the measure-specific data results in an authorization to proceed and a reservation of funds. After the measures are installed or implemented, the engineering staff will review the installation (or software changes). Repair work can be done in-house or by a service contractor. 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.
