充分利用太阳能和减少围护结构散热是建筑节能的两个主要途径。在太阳能建筑中,广泛使用两种传统的建筑材料——玻璃和岩棉。玻璃能使太阳辐射进入,并能阻止红外线辐射。岩棉等保温材料具有良好的绝热性能,常用于减少围护结构散热。但是,这两种材料都有缺点:玻璃虽透光但因传热系数大成为节能的薄弱环节,为了节约采暖能耗不得不限制其面积,但这样又不利于太阳能的利用。保 Making full use of solar energy and reducing the heat dissipation of enclosures are the two main approaches to building energy efficiency. In solar buildings, two traditional building materials are widely used - glass and rock wool. Glass allows solar radiation to enter and can block infrared radiation. Rock wool and other thermal insulation materials have good thermal insulation properties and are often used to reduce the heat dissipation of enclosure structures. However, these two kinds of materials have drawbacks: although the glass is transparent but the heat transfer coefficient is a weak link for energy saving, in order to save heating energy has to limit its area, but this is not conducive to the use of solar energy.
