[EnergyPlus_Support] The purpose of doing HVAC simulation

["brainwt" <deukwookim@xxxxxxxx>]

Dear All

I'm not a specialist on the field of HVAC engineering, but very curious about the purpose of HVAC simulation by EnergyPlus.

(If anyone want to know the energy performance of "building itself" from the architect point of view, it would be suitable to run by "IdealLoadAir" system.)

Anyway, what is the purpose of HVAC simulation using EnergyPlus? 

Possible answers would be,

1. to get more accurately calculated system sizes compared to RTS

2. to develop new control algorithms (night purge, setpoint reset, economizer control, etc) 

3. to check validity of the applied control algorithm

4. to develop new systems 

5. no special reasons, LEED requires it

6. other, please specify


Any comment would be appreciated. 

Thanks in advance.
