How does Sefaira calculate 'unmet hours'? I understand that this is the percentage of the number of hours in a year in which more than one room in the building is not "comfortable". I assume that "comfortable" is defined by the temperature range (rather than the setback range) of the HVAC system. What measure of thermal comfort is calculated for each room for comparison to the temperature range?
Furthermore, is there a relationship between unmet hours and dry bulb temperature?
I have been unable to find information about this in the offical Sefaira doccumentation and any help would be greatly appreciated! There are lots of tutorials that talk about thermal comfort but they all focus on dry bulb, operative temperature or ASHRAE.
