I am currently involved in the rehabilitation project of a set of school buildings located on the same grounds. The buildings are divided programmatically - classroom building, library building, sports hall building. The intervention includes replacing HVAC and lighting systems, replacing window frames and all interior finishes and furnishings. It will also eventually include the demolition and construction of interior partition walls. Since they are K-12 school buildings the joint certification of all buildings in the same certificate is a possibility (LEED Interpretation 10203: "K-12 school projects are eligible to include more than one physically distinct structure within a single LEED registration").
My questions are:
1) what is the most appropriate system in this case, BD+C or ID+C?
2) if you do not want to certify all campus buildings, can you certify some of the buildings within the same certificate and exclude the others from the certification?
3) If some of the buildings have programs with different levels of education, i.e., a building for preschool and another for elementary school, is it still possible to certify all buildings in a single certificate?
