The project at hand is ~500,000 sf and contains 4 buildings, each with 2 sub-floors, a ground floor, and between 4 and 11 stories and a district heating source. We are using the Application Guide for Multiple Buildings and the project has a Master Site, 1 block registration, and 1 single building registration. It is clear we need to demonstrate each buildings individual compliance, but we have the following questions: 1) Does each building need to be individually modeled with and without the district heating plant to demonstrate compliance; 2) Do EAp2 and EAc1 submittal forms need to be submitted for each building within the group; and 3) As the project is quite large our idea is to create a representative energy model by building out the geometry of the floors that are different, but then just multiplying the energy use of the floors that are identical rather than putting between 3 and 9 identical floors into the model - would this be acceptable to meet prerequisite and credit requirements?
