Retro-Commissioning Existing Buildings in New York State
The commissioning of existing buildings, referred to as “Retro-commissioning” (RCx), has gained prominence as a cost-effective strategy for improving energy performance. It is an independent process that takes place after construction, and is applied to buildings that have not previously been commissioned. RCx is a systematic process intended not only to optimize how equipment and systems operate, but also to optimize how the systems function together.
Cost-Shared Assistance for RCX Investigation
NYSERDA's Technical Assistance and FlexTech Programs provide outreach and cost-sharing assistance to building owners and property management firms interested in retro-commissioning. Both the Technical Assistance and FlexTech programs provide cost-shared energy studies and retro-commissioning investigations to identify building performance improvement opportunities and determine potential energy cost savings measures that could be achieved through retro-commissioning.
Building owners and property management firms interested in retro-commissioning their buildings may choose one of NYSERDA’s participating RCx Service Providers or FlexTech Contractors familiar with retro-commissioning. Those seeking technical assistance through NYSERDA’s FlexTech program must choose from the list of participating FlexTech contractors. If you choose to work with a contractor that is not listed as a participating FlexTech contractor, you may receive 50-50 cost-shared assistance through the Technical Assistance Program.
Commissioning New Buildings in New York State
NYSERDA promotes and supports better building design and construction practices such as commissioning. Commissioning is a process that starts at the beginning of the design process and culminates in the inspection, testing, balancing and verification that new building systems are operating properly and efficiently. Commissioning can reduce operating and maintenance costs, improve the comfort of a building's occupants, and extend the life of equipment. In addition, commissioning new construction projects can reduce construction delays, ensure the correct equipment is installed, reduce future maintenance costs and reduce employee absenteeism. Typically, returns for these commissioning services pay for themselves in energy savings in about a year. NYSERDA is currently offering several programs that are designed to encourage and standardize the commissioning of new buildings in New York State .
NYSERDA's New Construction Program (NCP) offers assistance to building owners interested in commisioning. Please see the NCP Web site for specific details on commisioning incentives.
