  • C111 Development of room temperature restraint method by the radiation reduction from the back side of steel roof

抄録

In summer, prefabricated buildings, warehouses, factories, etc., from the attic side of the building using a steel roof, there are much heat intrusion, room temperature rise has become a problem. As a countermeasure to prevent the intrusion into the room from the past of the roof, such as insulation materials or high solar reflectance paint to paint on the roof surface was mainstream. The heat from the attic surface into the room is generally transferred by convection and radiation. The high solar reflectance coating so as to suppress the heat intrusion by reflecting sunlight. The heat insulating material reduce the heat intrusion by lowering the attic surface temperature. In this study, we verified the mechanism of increased inhibitory effect of heat intrusion and room temperature and WBGT in the summer when you have painted a low emissivity paint in the attic surface of the prefabricated unit house.
