With an aging building stock, and owners reacting to increasing energy costs Retro-commissioning (RCx), or Existing Building Commissioning has come into being as a stand-alone engineering service.  RCx is a systematic, documented process that identifies low-cost operational and maintenance improvements in existing buildings and brings the buildings up to the design intentions of its current usage.  At Finn Projects, we draw on our experience in commercial, multi-residential and institutional buildings to provide RCx services.

RCx typically focuses on mechanical equipment, lighting and related controls.  RCx optimizes existing system performance, rather than relying on major equipment replacement.  The objective is to obtain improved indoor air quality, comfort, better control performance, and energy and resource efficiency.

Finn Projects' RCx process starts with our complete energy audit (see above).  We then conduct diagnostic monitoring and functional tests of all building systems.
