Hello Everyone,

I am preparing a project, which is going to be a newly constructed addition (horizontally) to an existing building. The existing building's function is warehouse/retail/offices and the new wing should be a warehouse with some office spaces. In this case the owner is the same and they will build-to-suit. The new addition is going to have own separate HVAC systems, etc.

In this situation, I have two options for the owner,

1) LEED BD+C NC Warehouses -> just for the addition which is separated from the non-certified building

2) LEED O+M -> for both the existing and the new addition, after it has been built (if they want to get a certification for the whole building)

My questions would be,

a) Are my options the right methods for the situation?

b) Can we do the NC for the addition, then O+M for the whole project?

c) Could you advise some guidance from USGBC documentation?

Thanks for your help!

Hi Dávid, I believe your numbered assumptions above are both correct: 1) LEED BD+C NC Warehouses -> just for the addition which is separated from the non-certified building (YES, YOU CAN DO THIS) 2) LEED O+M -> for both the existing and the new addition, after it has been built (if they want to get a certification for the whole building) (YES, YOU CAN ALSO DO THIS) For your questions: a) Are my options the right methods for the situation? (YES, I BELIEVE SO) b) Can we do the NC for the addition, then O+M for the whole project? (YES, THAT IS ALSO AN OPTION) c) Could you advise some guidance from USGBC documentation? (NOT SURE WHAT YOU MEAN...YOU NEED A REFERENCE FOR WHERE IT STATES THIS?)
