夏热冬冷地区围护结构建筑节能技术

夏热冬冷地区冬夏期间耗能都比较多，为降低能耗可采取以下方法：在可能的情况下，尽量避免建造东西向建筑，减少东西向外窗面积；不同朝向窗墙面积比不应超过０．２５（北向）、０．３０（东西向）、０．３５（南向）；建筑物体形系数宜控制在０．３０或０．３０以下；同时还应合理选用围护结构（包括墙体、屋顶、窗等）。

BUILDING' S HEAT-SAVING TECHNOLOGY OF PROTECTIVE STRUCTURE IN HOT SUMMER AND COLD WINTER DISTRICTS

In the hot summer and cold winter districts,the building's heat consumption has been comparatively enormous and costly.In order to reduce building's energy consumption,the following methods have been adopted namely:1,under certain conditions,it would avoid as much as possible of eastern-western facing buildings 2,reducing as much as possible of eastern-western facing windows' s areas 3,the diffierent various window facing area' s ratio should not be over 0.25(facing north),0.30(facing east-west),0.35(facing south)and 4,the building's volume coefficient should be controlled within 0.30 or under 0.30.Simultaneously an appropriate adoption of quality protective structure (including building's body,roof ,window etc.)should be well carried out.
