Our project team is building an addition to an existing facility. The owner would like to certify the whole building. The existing building was certified LEED EBOM about 6 years ago, but they have continued with sustainable improvements and would like to recertify the existing conditions along with the new building.

We are considering starting the performance period after construction is complete. It’s probably not logical to consider doing so but we have a chance that the square footage of new construction is just over the limit allowed in LEED EBOM. Clearly we would lose any construction credits including MRc3, MRc9 and IEQc1.5. Our intent is to Commission the building with a Level 2 audit and upgrade some of the mechanical systems in the process.

It certainly not standard operating procedure, but the building will be built in a green matter either way. Is there any reason why we would not be able to certify a building that has just finished construction?
