Post-Construction

Can this prerequisite be achieved if commissioning was not incorporated into the original design and construction phase? I am working with a building that was built and remained unoccupied for two years before deciding to pursue LEED-CS. We have commissioned the building post-construction, but will this be enough to comply?

Chris, Unfortunately I believe this project will not comply with the CS requirements. The intent of commissioning is for the CxAThe commissioning authority (CxA) is the individual designated to organize, lead, and review the completion of commissioning process activities. The CxA facilitates communication among the owner, designer, and contractor to ensure that complex systems are installed and function in accordance with the owner's project requirements. to establish the owners requirements and then ensure that the implementation and function of the building systems meet those requirements. A completed project excludes this capability by default.

The Refernce Guide requires that the commissioning agent review the OPROwner's project requirements (OPR) is a written document that details the ideas, concepts, and criteria that are determined by the owner to be important to the success of the project. and BODBasis of design (BOD) includes design information necessary to accomplish the owner's project requirements, including system descriptions, indoor environmental quality criteria, design assumptions, and references to applicable codes, standards, regulations, and guidelines. which must be done before final design (ideally before schematic design) and that commissioning must be incoporated into the construction documents. I am fairly confident that your project commissioning strategy would not be approved by the reviewer.

I am sorry for the bad news and my delay in responding to your question (I actually took a vacation).
