Revision history [back]

Hello,

I implemented a HVAC-System in my building with four thermal zones. For that I built an air loop, a hot water loop, a chilled water loop and a condenser loop. Every coil are attached to their water loop. But as I want to run the simulation the following error appears:

rogram Version,EnergyPlus, Version 9.2.0-921312fa1d, YMD=2019.12.15 18:30, * Severe * <root>[Coil:Cooling:Water][Coil Cooling Water 1] - Missing required property 'air_inlet_node_name'. * Severe * <root>[Coil:Cooling:Water][Coil Cooling Water 1] - Missing required property 'air_outlet_node_name'. * Severe * <root>[Coil:Heating:Water][Coil Heating Water 1] - Missing required property 'air_inlet_node_name'. * Severe * <root>[Coil:Heating:Water][Coil Heating Water 1] - Missing required property 'air_outlet_node_name'. * Fatal * Errors occurred on processing input file. Preceding condition(s) cause termination. ...Summary of Errors that led to program termination: ..... Reference severe error count=4 ..... Last severe error=<root>[Coil:Heating:Water][Coil Heating Water 1] - Missing required property 'air_outlet_node_name'. *** Warning: Node connection errors not checked - most system input has not been read (see previous warning). *** Fatal error -- final processing.

During Sizing: 0 Warning; 0 Severe Errors. *** EnergyPlus Terminated--Fatal Error Detected. 0 Warning; 4 Severe Errors; Elapsed Time=00hr 00min 0.45sec

I am a beginner and follow the steps of the book "Building Energy Modeling with OpenStudio" at checkpoint 7.

Does anyone know where the problem is and can help me please?
