Abstract
This research was conducted to study the performances of the heat and multilayer reflection insulators used for buildings in South Korea to realize eco-friendly, low-energy-consumption, green construction, and to contribute to energy consumption reduction in buildings and to the nation’s greenhouse gas emission reduction policy (targeting 30% reduction compared to BAU(business as usual) by 2020). The heat insulation performance test is about the temperatures on surfaces of test piece. The high air temperature and the low air temperature were measured to determine the overall heat transfer coefficient and thermal conductivity. The conclusions are drawn that the heat transmission coefficients for each type of existing reflection insulator are: A-1 (0.045 W/(m·K)), A-2 (0.031 W/(m·K)), A-3 (0.042 W/(m·K)), A-4 (0.078 W/(m·K)), and the average heat conductivity is 0.049 W/(m·K); The heat conductivity for each type of Styrofoam insulator are 0.030 W/(m·K) for B-1, 0.032 W/(m·K) for B-2, 0.037 W/(m·K) for B-3, 0.037 W/(m·K) for B-4, and the average heat conductivity is 0.035 W/(m·K) regardless of the thickness of the insulator; The heat conductivity values of the multilayer reflection insulators are converted based on the thickness and type C-1 (0.020 W/(m·K)), C-2 (0.018 W/(m·K)), C-3 (0.016 W/(m·K)), and C-4 (0.012 W/(m·K)); The multilayer reflection insulator keeps the indoor-side surface temperature high (during winter) or low (in summer), enhances the comfort of the building occupants, and conducts heating and moisture resistance to prevent dew condensation on the glass-outer-wall surface.
