Mainstreaming RCx in a Utility Program - Lessons Learned 1
Steven Long, P.E., Southern California Edison and Eliot Crowe, Portland Energy Conservation, Inc.
Retrocommissioning (RCx) commercial buildings is gaining recognition in the utility industry as a cost-effective means of achieving energy savings. Realizing “installed” savings from these programs has been difficult for a variety of reasons, including the difficulty and the effort required in quantifying savings and the persistence of measures. The design of recent programs has tried to address these issues and has also incorporated other related functions such as benchmarking. In some cases, the program design features have worked well, while in others, the design features inadvertently caused unforeseen problems.
This paper explores specific aspects of the 2006-2008 Southern California Edison (SCE) RCx program and summarizes program design, results to date, lessons learned, and how problems were addressed. The topics discussed include marketing, screening, benchmarking, owner commitments and timeline, qualification of providers, incentives/offer, baseline data and calculations, grocery store RCx, and peak demand reduction.
Some general information about the program results to date is also presented.
