CS-2009 EAp2:Minimum Energy Performance

% of Glazing & Floor Area Base Case vs Project

Hi, I am new to LEED and looking at the energy model submitted by our consultant for the compliance on EAp2. I have a basic question. Should the base case scenario and the real project be modelled with the same percentage of glazing and floor area? When comparing the input data I see these values are very different. It would seem as if we were comparing apples with pears, as these are buildings with different amount of windows and floor area. This is a C&S certification. Thank you for your support!

Floor area should be identical. Window Wall Ratio (WWR) should also be identical unless it is over 40%, in which case base should be at 40% and proposed should reflect actual WWR.
