Hi everyone,

We are working on one building that has 2 different programmes. But, only one is going under LEED certification. That means that in GF both programmes appear, but with clear different entrances and lobbies. Our doubt is if building footprint should consider this non-certificated programme as well, since it it one building as a whole? Or should limit to LEED boundary on GF?

Thanks for your time!

Hi Victoria, I had a similar situation where two separate projects were being collocated into one building, but similarly with very definite physical separations, no shared access or common hallways. For our projects (we actually had two of these simultaneously for a total of 4 separate LEED projects), we made the LEED boundary for each project only their portion of the total building. Similarly, we had to determine how to separate the site for each of the projects. You will need to do that based on what is appropriate for your building's site. Our two projects were funded separately, so it was relatively easy to determine the site areas that were allocated to each of the projects. If your site boundary is not as clear cut, you may want to determine what you think is logical and realistic for your project and contact LEED Coach to determine if your intended outcome is appropriate.

Victoria, as much as you can, consider the mechanical "boundary" when we start to define your LEED building - i.e. you should account for complete mechanical zones and not have the LEED boundary bisect any zones.
