For LEED ID+C project, Do we have to include the entire building for energy simulation modeling? or just tenant scope of work Thanks in advance

To demonstrate compliance using the performance method (Section 11) you will need to model the tenant space. This would include the scope of work plus components of the shell. I think this approach is rarely used in CI. Are you not able to meet the prescriptive requirements of 90.1 associated with the tenant scope of work?

We are pursuing Option 2 at EAc1.3 using an energy simulation according to Appendix G. Is the energy modelling according to Appendix G also applicable for this Prereq.? The reference guide doesn't provide a minimum percentage improvement!? Thanks in advance!

Option 2 under EAc1.3 does not require an Appendix G model. Simply beat the efficiency levels in Table 6.8.1A-G by the required percentages in the credit requirement to qualify. No modeling required. An Appendix G model is not an option for this prerequisite as it is not about energy saving calculation but rather about minimum code compliance.

Hi Marcus, Can you pls elaborate further on the above reply. how can we comply with the credit requirement without performing the energy modeling under option2? Is there any approach shared by GBCI/USGBC on this? If you are allowed to share, can you let us know how you have managed to get through this credit without simulation? Thanks Sriman

My previous statements regarding Option 2 for EAc1.3 were in error. That's what I get for reading the credit language and not the Reference Guide. It appears that modeling is required. I can envision using a simplified model or spreadsheet tool to demonstrate that the credit requirements have been met but the Reference Guide does not mention that as an option.
