I have a reviewer requesting that we oversize the PROPOSED case for a "possibly conditioned in the future" warehouse.
We have usually modeled the BASELINE case and PROPOSED case identical, then oversized the cooling and heating for the BASELINE by 1.15 and 1.25 respectively.
On this project, for some reason, he/she is requesting that we oversize the PROPOSED also "to make them identical"
My question is: is the identical requirement in Table G3.1 section 10.c & d prior to taking into account section G3.1.2.2 Equipment Capacities, or does it simply not apply when we have nothing defined. Or an erroneous interpretation on the reviewers part.
I do not have a USER'S MANUAL, that may explain it a little better, so I am also interpreting the way I have an all my previous project.
My interpretation is the Systems are identical, though the Capacities are adjusted in the BASELINE (oversized)
Thanks

Identical is modeled identically in all respects. Without a design the Proposed would also be over-sized identically according to G3.1.2.2. Think of it this way, since you do not have a proposed design you have to include the baseline system just as you would in the baseline. With that said there may be a sizing difference between the systems in the two models since both are auto-sized and it may be possible that the envelop and/or lighting are different.
