I was asked to create a LEED CS Scorecard for a project that is an addition of a floor added to the top of an existing multi-story LEED O&M certified building. I do not think CS is appropriate, as the owner will occupy the whole space. I am unsure if under O&M the client even needs to separately certify the space. All of the O&M credits have used the word "renovation", but I have not seen the word "addition". I felt that BD&C would be the most appropriate for this, if we had to certify it outside of the O&M, as it is an entire new space, including envelope. Thoughts?

This is definitely a "gray area" situation, Patty! It does sound like an addition to me, but to certify the addition separately fro the rest of the building they typically look at things like whether or not it has a separate mechanical system. Sounds like a question for GBCI.

When I worked on an ground floor addition to an existing college campus building that was connected to a basement renovation we got direction from USGBC to pursue CI. Their main rationale was that BD&C was a "whole building" rating system, and also the space was separated from the rest of the existing building by a secure entry, so CI for the addition made sense. The existing building was not LEED certified. In your case, the building is already certified with O&M, so in some respects it's not that different from an tenant improvement that modifies space within the certified building- same owner, maybe the same base building HVAC systems - which can be tracked under O&M per the TI guidelines and policies. I agree with Nadav it's a gray area that's worth checking with GBCI - let us know what you hear.

I'm working on a similar project right now and I think CI is the way to go, or else to wrap the new work into the next O&M certification. If O&M re-certification was going to be five years from now, then maybe re-certify earlier in order to incorporate the new work.

I agree with David and David. we have been in similar situations and have been instructed to pursue CI by GBCI. But always worth checking with GBCI prior to getting to far into the wrong scorecard. -David

Hi All, We are getting started on an interior renovation project for offices and learned that the building had previously been O&M certified. The O&M manual mentions "improvements" but it is unclear what extent of interior renovations will trigger a new ID+C application vs O+M recertification. The building will remain under the same ownership and occupying organization. Anyone have experience with this before we reach out to GBCI? thanks!
