RE: [EnergyPlus_Support] Re: 2 Pipe Fan Coil Unit for Cooling + Radiant floor for heating





Here’s an example:

You may assign heating and cooling priorities for all zone equipment.

 

The Building Performance Team
James V. Dirkes II, P.E., BEMP , LEED AP
1631 Acacia Drive NW
Grand Rapids, MI 49504

The I/O file also says that it will use the heating equipment priority to determine which system runs first. Can somebody elaborate on how to determine what the priority is and how to change it.

Thanks,
Shubha
