Dear all, I am modeling a C&S project (large shopping mall). For the process loads, I am using: - For the Core Areas: ASHRAE 90.1 User's Manual - Page G32 - Table G-B - For the tenanted areas: LEED Reference Guide - Page 616 - Table 1 (CS Appendix 2) 1) Is this correct? 2) Is it normal to have my process costs at ~14% based on these tables? I will upload a detailed table demonstrating how I got this 14% based on the references I listed above. Many thanks,

This approach meets the minimum requirements. However for the core areas a better approach would be to work with the owner to determine the likely equipment being used in those areas and model what will be installated not some assumption from a book. This would give you an opportunity to evaluate what is being installed to see if there are opportunities to reduce energy usage. This is the point of energy modeling. Not minimum compliance for LEED.
