1) Make sure your zoning pattern will not require any reheat. Certain VAV
zones served by the same system may require reheat if the central ahu
supplies much cooler air than what is required by some zones.
2) If there is no heating system in your building you should not include it
in the model. Make sure the heating system is set to Not installed. Then
the heating setpoint does not even matter.
