摘要
外窗作为建筑围护结构的重要部组成部件,起着与外部光、热环境进行隔离或交换的作用,对调节室内热舒适性、改善空气质量以及必要的照明起着至关重要的作用。在亚热带地区,由于其特殊的气候特征,建筑节能既要考虑夏季隔热,又要兼顾冬季保温,因此外窗的节能设计就显得尤为重要。本文以住房和城乡建设部、财政部可再生能源建筑应用示范项目为例,通过建筑构造技术设计,提出了亚热带地区不同建筑围护结构各朝向气候适应性窗的概念,通过计算机模拟分析与实验测试,对该窗的夏季隔热和冬季保温效果进行了验证。本文所介绍的构造技术强化了气候适应性窗在区域气候方面的得热优势并弱化了其不利影响,为亚热带地区建筑外窗的设计提供了新的思路。
As the major component of building envelope,external window plays the function of insulating and exchanging light and heat with outside environment,which is very important for the building to regulate the indoor thermal comfort,improve the indoor air quality and supply necessary lighting.In the subtropical area,for building energy conservation,the heat insulation in summer as well as heat preservation in winter with special climatic characteristics should be taken into account.Consequently,it is most significant of all to realize energy-saving design for external window.In this paper,taking the Building Sample Application Projects of Renewable Energy Sources Supported by Ministry of Housing and Urban-Rural Development and Finance Ministry as an example,a new climatic adaptive window conception in different directions of building envelope for subtropical area was proposed with the application of building construction technology.Based on the computer simulation and measurement,the windows＇ effectiveness of heat insulation in summer and heat preservation in winter was verified.As a result,the heat receiving advantages of window were strengthened and its adverse effects were weakened according to the regional climate conditions,and therefore,a new design method for external window in subtropical area was provided.
