In EnergyPlus, I have previously used the Hybrid Ventilation module with natural ventilation (ZoneVentilation:WindandStackOpenArea) and mechanical ventilation (both HVACTemplate:Zone:IdealLoadsAirSystem and HVACTemplate:Zone:PTHP).

However, ZoneEarthTube objects do not have an individual name, and are only specific to a given zone, which does not allow a direct use in AvailabilityManager:HybridVentilation.

I would like to use ZoneEarthTube as natural ventilation, to replace mechanical ventilation whenever conditions apply.

How would be the best way to go around this? Would adding a name input to ZoneEarthTube (and, respectively, chaning the Input Data Dictionary file)? or would this also require a change to what AvailabilityManager:HybridVentilation allows as natural ventilation?
