摘　　要：国内外对冷屋面用反射型隔热涂料节能效果的评价方法,有涂层稳态表面温度、等效热阻以及建筑能耗模拟分析等。其中,等效热阻法在建筑节能设计中应用简便、易操作。从理论和上海静安科技馆40 mm PU屋面的应用实例证实,热反射隔热屋面节能效果显著。The evaluation methods of reflective thermal insulating coatings for cool roofs in China and abroad are introduced including the surface temperature of the coating by steady-state approximation, equivalent thermal resistance calculation, and simulation analysis of building energy consumption. The method of equivalent thermal resistance calculation is straightforward approach for energy-efficient design of buildings. The obvious energy efficiency achieved by reflective thermal insulating roofs is approved by the case of 40 mm PU roof of Jing＇an Science Museum in Shanghai and in theory.
