Thermal comfort for car occupants is important factor for automotive design. We have been developing the numerical simulator for the prediction of the thermal environment and thermal comfort in vehicles. In the previous paper, the comprehensive combined analysis method with multi-node thermoregulation model, radiation model and CFD (Computational Fluid Dynamics) is proposed. In this paper, the applications of this method to car occupants are presented. We focused on investigating the effects of glass properties on thermal environment of compartment and thermal comfort for passengers. The calculated results were compared every part of glazing, front windshield, front sidelite and rear sidelite in summer condition. It was found that the differences of air temperature between normal glass glazing and functional one are not so much but the differences of human feeling are significant. Further more, the effects of functional glass on the reduction of air-conditioning power are simulated. This simulator was a useful tool for investigating the thermal environment differences between solar reduction glass and normal glass clear, which enable to make the effects of functional glass clear from the view point of thermal comfort.
