We have a 2-story bldg. over 25,000 sq.ft. that has offices and anicllary spaces; one adjacent 2-story high theater; and one adjacent 2-story high Gym.

We are modeling it as one HVAC system for the 1st Floor and one HVAC system for the 2nd Floor (VAV, #6). Then, we are modeling the Theater as a separate HVAC heat pump system and the Gym as a separate HVAC heat pump system as well (CV, #4).

Is our modeling approach correct ?

Thank you in advance for any input/answer.
