how to calculate the thermal comfort in designbuilder [closed]

edit

in my project i have a VRF in my detailled HVAC system when i stimulate i have some confusing results C:\fakepath\az.PNG in summer months all hours are uncomfortable things that i find really absurd my heating and cooling setpoint are 20 and 24 also when i stimulate the air temperature (in simulation is above 24 in summer) but in cooling design is 24 what's the diffrence between the air temperature in cooling design and in simulation
