Baseline building should always be just providing the minimum outdoor air 
ventilation rate required by 62.1. It should never be increased. For proposed, 
it just means that your OA should never be below the minimum OA requirement of 
62.1. Now if the design chooses to pursue 30% more OA. Then you should reflect 
in your model what is in the design. G3.1.2.5 just wants to make sure that you 
do not model your proposed to be below the minimum OA. Providing 30% more OA can 
earn you a credit but it will affect your EAc1.
