Effect of Heat-Reflective Insulation Coating of Building Energy Saving in Summer
In order to discuss the effect of energy saving of heat-reflective insulation coating on exterior walls of building, the wall temperature change of two test rooms with heat insulation or not in Hangzhou has been monitored in summer, and the heat flux data of east, south and west walls were analyzed. The results indicate that the reflective coatings reduce the exterior surface temperature by up to 7 to 8 °C. The reduction in heat gain of east, south and west walls is significant, which is the cooling effect. The total surface heat gain of exterior walls without reflective coatings is 2.44 times larger than those without them. In particular, the heat gain of walls with reflective coatings is nearly 5.27 times more than that of walls without reflective coatings. The reduction in electricity consumption of air-conditioning system in the building with reflective coatings is 2.5 kWh/m2 per month by calculation, which well proves the energy saving effect of reflective coatings.
