Simulation of Radiation Heat Flux Effect in Buildings on Human Thermal Comfort Under Transient Conditions

The purpose of this study is to investigate the effect of radiation heat flux from lighting lamps in buildings on human thermal comfort. In order to obtain the thermal responses of human body exposed to radiation heat flux from lighting lamps, a mathematical model based on Gagge model with some modifications were developed and the effect of radiation heat flux from lighting lamps on human thermal comfort was examined under transient conditions. The human body was divided into 16 sedentary segments and the variation of sensible, latent heat losses, and skin wettedness were calculated under radiation effect in buildings.
