I used the PNNL model for Full service Restaurant (https://www.energycodes.gov/prototype-building-models#Commercial)
Iam using Energyplus 9.5 and the model is reporting error like this
* Severe * CheckAirLoopFlowBalance: AirLoopHVAC PSZ-AC_2:2 is unbalanced. Supply is > return plus outdoor air.
* ~~~ * Environment=RUNPERIOD 1, at Simulation time=08/24 03:40 - 03:50
* ~~~ * Flows [m3/s at standard density]: Supply=8.388132E-004 Return=0.000000 Outdoor Air=0.000000
* ~~~ * Imbalance=8.388132E-004
No changes done on the model other than updating to the latest version How to fix this issue?? Thanks in advance.
