Unusually High Cooling, Pump, and Heat Rejection Energy Values in Weekly Ironbug/Honeybee Simulation

[Dhanushkodi]

Hi everyone,

I am working on an HVAC simulation in Ironbug/Honeybee and I am facing an issue with unusually high energy values during a 1-week simulation period. I would appreciate any help in diagnosing whether this is a modeling issue, or HVAC configuration problem.

Could this happen because:

• all 42 zones are connected to a single air loop,

• chiller sizing/control issues,

• plant loop temperature settings,

• duplicate HVAC assignments,

• or schedule problems?

I have attached the Details of Air Loop, CHW Loop and CW loop.

Thanks in Advance
