Hi everyone, I am trying to directly calculate the energy balance (sensible heating/cooling) for the air node in a MixedAir model to determine the exact heating/cooling load components. To evaluate the heat balance, I considered the following key factors: > 1) Internal Convective Heat Gain Rate > > 2) Surface Convection Rate > > 3) Outdoor Air Transfer Rate > > 4) System Ai...

I have an ERV which is providing a maximum airflow through the heatwheel. This maximum is below the ASHRAE 62.1 minimum for the system that it is connected to. The ERV does have still an OA bypass. How do I set the maximum amount of air that can flow through the ERV so that the ERV air + the extra OA needed by the zone 62.1 minimum will go into the mixed air loop in my AHU?

 Is this a known compatibility issue between OpenStudio Application 1.11.1 and this specific SketchUp 2026 build, and if so, is there a fix or newer plug-in build in progress?

Can we add a schedule file in OpenStudio without using a measure? In OpenStudio, I can load the schedule file, but I cannot apply it, or I may have missed something. When using a measure, I was able to apply the schedule file. But without using the measure, after loading the schedule file in OpenStudio, I assumed it should appear in the library on the right side, but I could not...

I am working on a relatively simple model for a natatorium, based on an AirLoopHVAC and a PlantLoop. The air temperature setpoint is around 82 F with nighttime setback +/- 3 F for cooling/heating, and the pool temperature setpoint is around 80 F. The air humidity setpoint is around 50%, with nighttime setback +/- 10% for cooling/heating. I don't know if I will need the setbacks ...
