Error on the system outdoor air method

Hi all

By using ladybug tools HVAC systems; PVAV with central heatpump i faced this error:

  1. ** Severe ** Sizing:System - The system outdoor air method is set to VRP in 2 ZONE PVAV

I was wondering if you can help me on this issue.


Hi @Mariafa ,

That’s not an error. It’s a warning letting you know that the outdoor air method is being set to Ventilation Rate Procedure (VRP). The simulation will still proceed but EnergyPlus just wants you to be aware that this is happening.
