美国建筑设计采用的节能手法有:1.双重外墙:把建筑物的外墙作成里外两层,中间留有一定空间,并控制中间的空气流动。2.采光竖井:为解决室内部分空间日光少的问题,大型建筑较普遍地设置采光竖井。3.水平挑檐:在建筑物窗外设水平挑檐,既可遮挡直射日光,又可利用水平挑檐将日光反射到室内天花板,以节约照明能源。4.节能窗玻璃:多层窗玻璃的最外层内侧涂有特殊金属膜,可以有选择地反射辐射线。5.主动式太阳能系统:在设计合理与日照量充足时,可为集热器面积2~3倍的建筑面积提供采暖制冷。
Energy-saving techniques used in the US architectural design include: 1. Double external walls: Make the external walls of the building two layers inside and out, leaving some space in the middle, and control the air flow in the middle. 2. Lighting Shaft: In order to solve the problem of less sunlight in the interior part of the room, large-scale buildings are generally equipped with lighting shafts. 3. Horizontal provocation: Provocation at the exterior level of the architectural window can not only block direct sunlight, but also use horizontal provocation to reflect sunlight to the interior ceiling to save lighting energy. 4. Energy-saving glazing: The innermost layer of the multilayer glazing is coated with a special metal film that selectively reflects the radiation. 5. Active solar energy system: When the design is reasonable and the amount of solar radiation is sufficient, it can provide heating and cooling for the building area of 2~3 times of collector area.
