Hi,
We have a project that includes a Hangar, with two levels of administrative offices and workshop area in one 250,000sf building. Adjacent to the building (80ft away) and separated only by pavement and greenery, is a 2 floor 25,000sf amenities building which will function as a controlled access (where workers must go through security before getting to the hangar) and will include services such as gym, dining, showers, that will be used daily by the Hangar´s workers (hangar has restrooms but no showers, lockers or cafeteria). Both buildings will be built simultaneously in an isolated area of the airport, where there will be a controlled access (through amenities building) allowing for entry only to hangar workers, office employees, personnel, and a few other transients. Would it be possible to register the project under the same LEED NC certification or would it be necessary to register 2 projects?
Thank you!

I used to submit this configuration and the review called for the mid-review to clarify the LEED boundary. This cause the project to delay for 2 month and we needed to revise the documents and resubmitted as only one building.
So, you should try to separate them with appropriate boundary or you could submit it as "Multiple Buildings in a campus site" scenario.

Jatuwat, thank you for your answer. In the LEEDv4 BD+C Reference Guide is stated: "If the project consists of multiple structures physically connected only by circulation, parking or mechanical/storage rooms, it may be considered a single building for LEED purposes if the structures have programmatic dependency (spaces, not personnel, within the building cannot function independently without the other building)..."
So I thought this might apply, although physical connection between buildings is not enclosed (the pavement and greenery are open space), but the reference guide does not specify on this.
Plus, there definitely is programmatic dependency between both buildings: the amenities building´s purpose is to provide access control, showers and cafeteria services to hangar´s workers, which are necessary and hangar building will not provide them. I don´t know if this would be a valid justification.

Hi Miriam,
We have a very similar situation with one of our projects - how did you end up proceeding, as one building or multiple buildings?
Thanks for any insight!

Hi!
I asked the GBCI and sent renderings of the project, the conclusion was that they were two physically-distinct buildings and for the purposes of LEED, they had to be considered as two separate buildings.
So the 3 options were:
1. Certify them as completely separate projects, each claiming a portion of the site as its own LEED project boundary
2. Group approach
3. Campus (or Master Site) approach
I hope that helps, but if you still have doubts I would recommend you write a question directly to the GBCI so they can review your particular case. Good luck!
