拉萨居住建筑空间模式与室内热环境的关系研究

RELATIONSHIPS BETWEEN SPATIAL PATTERNS OF RESIDENTIAL BUILDINGS AND THE INDOOR THERMAL ENVIRONMENT IN LHASA

为了解决建筑设计节能问题,选取四户不同空间形态和模式的民居,对其室内外空气温、湿度及壁面温度进行定量实测和分析,并结合DesignBuilder软件进行模拟验证,研究建筑空间模式与室内热环境的关系。分析表明:建筑中某一单元的南边房间数量越多,室内的温度越低,北侧房间越多,温度越高;阳光间与相邻房间之间的隔断在白天不利于室内温度上升,在夜间有利于维持室内的温度;直接受益式房间的进深越小,温度越高,当房间位于东南侧,该现象尤其明显。

In order to solve the problem of energy conservation for an apartment in building design,four dwellings with different space forms and modes were selected,and the actual measurement method was adopted to quantitatively teste and analyze the indoor and outdoor air temperatures and humidity and wall temperatures,combined with DesignBuilder software for simulation verifiction,and the relationship of building space modes and the indoor thermal environment was studied.The analysis showed that:1)The greater the number of rooms on the south in a building,the lower the temperture of the apartment,and the more rooms on the north,the higher the temperature;2)The partition between the sun room and the adjacent room was not conducive to the rise of room temperatures during days and was beneficial to maintaining room temperatures at nights.3)The smaller the depths of directly profitable rooms,the higher the temperatures.This phenomenon was especially obvious when apartments faced southeast.
