I am working on a project that is a part of campus. This project will be located next to a 4-story existing parking garage shared by other adjacent non-LEED certified buildings. The question I have is whether this parking garage needs to be included to the LEED project boundary. If so, does the garage need to comply LEED prerequisites and credits as well? If the existing parking garage should be included to the project boundary, this will include existing hardscape and landscape features around the garage as well. Does this mean the irrigation water calculation needs to include the existing irrigation area around the garage?
