Our client constructed a 10 story healthcare building about a couple of years ago. Only the core and shell was constructed at that time. No interior build-out was part of the construction then.
Currently, three of the ten floors are in the process of being built out. Additionally, they intend to build out some of the other floors in the near future.
One scenario is to pursue LEED for Commercial Interiors certification only for the floors that are undergoing interior-build out. Under this scenario only the specific floors will be LEED Certified.
They are interested in pursuing LEED certification for the entire building.
Can we pursue LEED Core and Shell certification for the entire building? How would this reflect on the floors undergoing interior-build out?
Would LEED-EBOM be applicable at all here?

CI was designed for situations like what you describe: an interior build out of some of the floors in a core and shell building.
In a multi-tenant office building, you would normally pursue CI for each phase of the interior build out and have each tenant space get its own plaque. If all the space is going to be occupied by one tenant but built out in more than one phase, you could collect all the documentation for each phase and combine them all at the end for one certification.
It would be almost impossible to certify a previously constructed building under Core and Shell – it’s too late for commissioning, tracking construction waste, and documenting the IAQ plan, VOC compliance and all material purchases.
EB O&M is a good option if the building owner wants to address the operational issues and ongoing energy performance of the building. It can be difficult to collect and manage all that data in a multi-tenant building, though, so would take more work. Still, it’s a better reflection of the ongoing environmental performance of the building. We’ve seen older office building pursue LEED EB O&M to stay competitive with newer office buildings that had pursued LEED NC during construction.
