Existing Building Commissioning

Our existing building commissioning projects are performed with specific goals such as improving energy consumption or mitigating indoor environment quality (IEQ) problems. Achieving these goals through existing building commissioning involves identifying the root problems of poor building performance as it relates to such issues as improper equipment maintenance, mechanical system design, and control problems. We recommend resolutions and coordinate the implementation of any modifications made to building systems, and help ensure that all operational issues have been addressed.

Approach to Existing Building Commissioning (EBCx)

There is a broad range of approaches to commissioning. The following is the generally accepted approach by most organizations. Each project must be reviewed on a case by case basis to determine the most appropriate approach.

Planning: EBCx provider is selected and EBCx goals are set. Setting appropriate goals are critical. An EBCx project can be for a variety of reasons including improving IEQ, occupant comfort, energy consumption, or a combination of these goals. It is important to clearly define the expectations as they can conflict.

Investigation: This can sometimes be broken up into more than one effort, a preliminary review then a more detailed review. It is important to remain flexible depending on what issues are discovered. Documentation is gathered and reviewed, people are interviewed and short term testing and monitoring is performed.

Implementation: In this phase the issues are corrected and re-tested to verify effectiveness. If the problems are relatively simple, then not a great deal of design work or planning needs to go into the correction of issues. Sometimes, complete capital upgrades are required to correct the problem.

Hand-off: In this phase the owner is given the documentation, training and tools to make the corrections sustainable.
