LEED-CI Commissioned system
I have a question concerning commissioned systems.
The office which I would like to certify with LEED CI will have only interior lighting changed. In view of that should the CxA commission systems which have not been changed in the office or should it only commission the new systems?

The CxA is required to commission the HVAC&R and associated controls, lighting and daylighting controls, domestic hot water systems, and renewable energy systems regardless of existing or new. Just because they are existing does not mean they funtion correctly or meet the new/revised function of the space. In my experience I typically find more issues with existing mechanical systems than with new systems when commissioning.

David has a good point that providing commissioning for existing equipment is beneficial but it is not required for LEED-CI certification. The LEED-CI Reference Guide states, “For commercial interior projects, the scope can vary tremendously. Some may include only lighting systems, whereas others may include all HVAC, service water, and lighting systems.” The bottom line is that you are only required to commission the systems included the project scope.
