This project consists of seven separate buildings on a shared contiguous "campus" site, including four office buildings, one retail building, one hotel, and one multifamily residential building. The project will be designed concurrently, and then built by the same owner in two successive phases, with each phase expected to take two years. Our intent is to pursue LEED certification of the buildings as follows: - Certification #1: One office building (Phase I, core and shell) - Certification #2: Four office/retail buildings (Phase II, core and shell) - Certification #3: One Hotel, residential, retail building (Phase I, new construction) - Certification #4: One Multifamily residential building (Phase II, new construction) The project boundary includes all seven buildings, including shared parking, and other site infrastructure including stormwater systems, etc. Given that the project will be submitting each phase separately, and under multiple rating systems (CS and NC), we are seeking guidance as to how to document those site credits which are common to the "campus" site. Can the Application guide for Multiple Buildings and On-Campus Building Projects be used across rating systems (CS and NC) for credits for which the requirements for each rating system is the same (e.g. SSc5.1)? Similarly, can the Campus Guide be used across different Phases? For example, for SSc5.1, the project would like to demonstrate that in aggregate, the project has sufficient open space, per the LEED requirements (in both CS and NC), to meet the credit for each of the buildings, even if individual buildings per their allocated LEED boundaries do not. The Campus guide supports this approach: "For previously developed sites where there are multiple buildings in the project scope, enter aggregate data in the Submittal Template, as appropriate". Furthermore, we believe that the CIR dated 4-18-2003 regarding SS credits and campus approach further supports this approach. We would like clarification as to whether this approach is acceptable where there are multiple rating systems (CS and NC) at play. Or whether open space requirements will need to be met for each individual LEED building / project boundary (four in all) for the project.
