I keep receiving the following error when I try to apply a measure:
This error does not only occur when I apply this measure. It pretty much happens when I apply any measure.
I don't think it occurs on "any measure". This is a logic error, clearly, as indicated by the Optional not initialized.
In this specific example, it's happening here: https://github.com/NREL/openstudio-ex...
Meaning your Space does not have a ThermalZone attached to it...
And you're hitting it on any measure that does use that os_lib_hvac.rb's createPrimaryAirLoops function.
Unfortunately, the function is wrong (openstudio-extension-gem 0.7.0 and 0.7.1 are affected at least, but that function was removed for the forthcoming release...):
if space.thermalZone
thermal_zone = space.thermalZone.get
Should actually be
if space.thermalZone.is_initialized # alternative: !space.thermalZone.empty?
thermal_zone = space.thermalZone.get
Anyways: to work around your issue, please assign a ThermalZone to all of your Spaces. A Space must have a thermal zone in order to be simulated by E+.
Oh! I have a few spaces that are not assigned a thermal space because I was not planning on assigning an HVAC system to it.
Thank you!
They still should have a ThermalZone assigned. The ThermalZone does not require a thermostat nor HVAC equipment though.
If this solved your issue, please mark the answer as accepted so the thread is marked as resolved. Thanks
