复合墙体保温层位置和厚度对建筑能耗的影响

采用清华大学开发的商业版建筑能耗计算软件DeST-c对典型办公建筑在6种外墙保温方式下以及在5个不同城市当中的建筑全年累计冷、热负荷进行了模拟计算。这6种外墙保温方式分别是内保温、外保温、中间保温、一半内一半外保温、一半中间一半内保温、一半中间一半外保温。这5个城市分别是哈尔滨、西安、上海、昆明、广州。采用生命周期耗费分析法对典型办公建筑在这5个不同城市当中的保温层经济厚度进行了计算,并根据计算结果对我国5个不同气候区域的外墙保温技术进行了一定的分析。

Effects of Insulation Position and Thickness of Composite Wall on Building Energy Consumption

Heating load and cooling load of commercial building with six kinds of composite walls in five cities of our country are calculated by software named DeST-c which is developed by Tsinghua University. These six kinds of composite walls are respectively characterized by placing insulation at the inner surface of wall, placing insulation at the outer surface of wall, placing insulation in the middle of wall, placing half insulation at the inner surface and the other half insulation at the outer surface of wall, placing half insulation in the middle and the other half insulation at the inner surface of wall, placing half insulation in the middle and the other half insulation at the outer surface of wall. These five cities include Harbin, Xi＇an, Shanghai, Kunming and Guangzhou. Besides, economic insulation thicknesses of this building in five cities are calculated by life cycle cost analysis method. According to the results, the technology of wall insulation in different areas is analyzed.
