There is a simple fully closed glassed zone without any infiltration, ventilation or HVAC system. The floor is bare ground and there is no basement or slab. In this case the zone temperature should be around 60C in winter and 100C in summer. but it is around 20C in winter and 45C in summer. why?
It is modeled by EnergyPlus 9.0.1
This is the model: File Link
