My building has four floors, and 4th flr is left empty for future use. I did not include it in simulation, so I got the comments from the reviewer: Revise the model as necessary to include all unfinished space, and to model any unfinished lighting, HVAC, and receptacle systems identically in the baseline and proposed case, consistent with ASHRAE 90.1 baseline requirements.
On the other hand, the owner has identified the design of 4th flr will be the same as 3rd flr, current system has taken 4th flr into account.
My question is how to simulation 4th flr in proposed model? Should I use the parameters on 3rd flr or refer to baseline model?
