Hii, How can I model an ‘IdealLoadsAirSystem’ in my model (openstudioapplication-1.7.0) to extrapolate the thermal load outputs (cooling/heating) given by the building envelope alone? Version: openstudioapplication-1.7.0 Model: https://drive.google.com/drive/folder... Thank you
You can turn on Ideal air loads on the Thermal Zones tab 
@Alisacusu : You also need heating/cooling thermostats (no thermostats == no ideal heating/cooling loads). Several geometry issues. In the Geometry tab, activate Geometry Diagnostics, then click on Space Level Issues/Incorrectly, then Space Level Issues/Non-Enclosed, then Potential Adjacency Issues/Enable : OpenStudio will highlight problem surfaces. You'll likely need to activate Output Diagnostics/Enable DisplayExtraWarnings in the Simulation Settings (and run a quick 1-day simulation) to isolate the surface issues to fix.
