I'm hoping someone knows the anser to this question. For the LEED ND certification the minimum requirement is "The LEED project should contain at least two habitable buildings and be no larger than 1500 acres." Does habitable mean buildings with dwelling units?

Has anyone pursued the schools Mold Prevention IEQc10 successfully and have format for the documentation created they would be comfortable sharing? Our contractor is excited about pursuing this credit but no on our team has pursued it before.

thanks in advance!
