This appears to be a bug that affects thermal comfort when the ClothingInsulationSchedule method is chosen for the Clothing Insulation Calculation Method. The lack of documentation for the Zone Thermal Comfort Clothing Value is also an issue.
The good news is two-fold. First, from the code, it appears that this is just a reporting issue for this variable. The code is using the correct value for calculating thermal comfort based on the user defined clothing value. For some reason though, with the ClothingInsulationSchedule, the line of code that also assigns the reporting variable is missing.
Second, there is a temporary work-around. Change the Zone Thermal Comfort Clothing Value to CalculationMethodSchedule and then set the Clothing Insulation Calculation Method Schedule Name to a schedule that is always 1 (which tells E+ to use the clothing insulation schedule all of the time). I tested this and was able to get something other than 0 to show up for the Zone Thermal Comfort Clothing Value output variable.
I will log this as a bug and plan to work on it as soon as possible. Hopefully, this fix will make it for the V25.2 release. Thanks for bringing this to our attention!
