CS-2009 EAp2: Minimum Energy Performance
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,

A portion of our building envelope is historic. Can we exclude it from our model?
For an existing building, do I need to rotate the model?
Our process load is higher than 25%. Do we have to justify that?
Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?
Can mezzanines open to floors below be excluded from the energy model?
How do I provide a zip code for an international location?
For a project outside the U.S., how do I determine the climate zone?
For a project outside the U.S., how do I determine the Target Finder score?
Do hotel rooms need automatic light shut-off control?
How commonly are the 90.1 mandatory compliance forms submitted as part of EAp2/EAc1?
The Section 9 space-by-space method does not include residential space types. What should I use?
Can the Passive House Planning Package (PHPP) be used to energy model for LEED?
Which baseline HVAC system do I use if my building has no heating or air conditioning?
Our project has a diesel backup generator. Should we include it in our energy model?
Can SHGC be higher in the proposed than in the baseline model?

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.
