The purpose of the present invention is to provide a system for estimating the heat load of a perimeter zone in which the heat load of a perimeter zone can be highly accurately detected without providing a dedicated detection device, such as a radiation thermometer, for detecting the heat load. This system for estimating the heat load of a perimeter zone is characterized in being provided with a light-transmissive solar cell installed on a window surface, and a heat load estimation means for estimating the heat load of the perimeter zone on the basis of output characteristics of the solar cell, the heat load estimation means determining the temperature of the solar cell and the amount of solar radiation from the window surface on the basis of the open-circuit voltage value and the short-circuit current value caused by power generated by the solar cell, and calculating the average radiation temperature of the perimeter zone using the temperature of the solar cell and the amount of solar radiation. |
