This paper describes several improvements and application of thermal physiological and psychological prediction system. First, we performed examination to evaluate the comprehensive effect of floor heating system on physiological and psychological responses. Secondly, we proposed a new evaluation method to predict thermal sensation vote by using an advanced prediction system. In addition several numerical simulations of whole body temperatures and thermal psychological responses were performed with our system. The results suggested that the present advanced system had high usability. Finally, we applied the system and predict the optimum floor temperature when using floor heating system.
