Energy Modeling for a Group Certification

We are working on an open-air shopping mall with 6 buildings arranged around a main "street". Some are attached and some aren't. There is also a parking structure contiguous with 3 of the buildings. We plan to register the project under LEED-CS for a Group Certification. When certifying buildings under the Application Guide for Multiple Buildings & On-Campus Building Projects, according to Appendix A, each building part of a multiple building LEED application must individually meet the requirement of EAp2; the buildings will be aggregated for EAc1. Questions: · Is common area/site lighting, including that in grounds and structured parking, apportioned to each building in the application? · Would apportionment be done on the basis of the area of any one building as a percentage of the total area of all the buildings? · Is common area photovoltaic or other renewable energy system apportioned in the same way to each building? · Is photovoltaic or another renewable energy system installed on one building and which the energy is applied to common area usage apportioned to each building or must it be assigned to the building on which it is installed?
