Inquiry

This project is seeking a single LEED-CS certification for 12 free standing structures in close proximity at a single retail outlet shopping mall. Per ASHRAE 90.1-App. G protocol, each structure will be modeled individually to accurately represent the thermal envelope and building orientation comparisons. When inputting information into the EA credit-1 online template, should the energy performance for all twelve buildings be totaled and input as a single amount for both baseline and proposed (i.e. will a single EA template input be allowed by adding the energy model performance of each structure to reach a total for input on the template)? The alternative would be treating each structure individually (12 EA template inputs) and averaging all energy performance differentials to determine the total project EA credit.
