Hi Sir

We are working in a  project which has a conditioned area of  >240,000 ft2 and G+11 floors. We consider exceptions to G3.1.1 due to varying operational schedule of the building and designed with single zone systems conforming with the requirements of system 4 for certain zones.

Now the query is either we want to consider the total cooling tons of the building or only the cooling tons of the chiller alone for baseline chiller selection.

Thanks in Advance.
