All,
I am modeling a library that has a mix of air-cooled roof top units and
water-cooled packaged AC units with a cooling tower. Based on floors,
square footage, and heating type, it falls under ASHRAE App-G baseline
system 5.

My question: Should the baseline systems be all air cooled? Or should it
match the proposed system, including both air cooled units and water
cooled units with a cooling tower?

Thanks for your input,

Sam Mason
