Hello, In the project that I manage is summarized in a rehabilitation of an existing building in which rehabilitates all floors. Also 2 mezzanines are constructed in two different plants that increase the total building floor space. These new plants are considered new construction gross square footage? For MR Credit C1.1, the option to follow is The LEED project does not include any additions? or The LEED project includes an existing building with one or more additions. Regards

Victor, I don't think adding interior mezzanines would count as adding new construction gross square footage in regards to LEED. Having a physical building addition like a new wing (with new MEP systems & new building envelope) to an existing building is what the addition is for MRc1.1. I would recommend explaining this in your PIf4 general project narrative so it's clear for USGBC.

I have a similar question, but just want to clarify. We are reusing an existing church structure, adding two floors within the existing volume, and then also adding an adjacent building with a connector between. When completing PI Form 2, should we include the two new floors added within the exisitng building under "Existing, renovated gsf"? If we include it in "Total gsf" but not also in "Existing, renovated gsf", we get an error message on the form. But it also doesn't really make sense to include these floors in "New construction gsf." I'm trying to clarify because this is impacting our MRc1.1 qualification.... thanks!
