摘　　要：拉萨拥有丰富的太阳能资源,但海拔高,冬季极寒,照度和室内热舒适度是影响拉萨民居室内环境质量的关键指标,而外窗遮阳构件尺寸对二者均产生显著的影响。目前针对西藏传统民居的遮阳构件光热性能的研究较少,且缺少定量分析。本文以照度和热舒适性作为优化目标,运用遗传算法对拉萨传统民居典型空间的遮阳构件尺寸进行多目标优化计算,得出拉萨民居适宜的遮阳构件最优尺寸范围,为拉萨民居的光热环境改善提供科学依据。Lhasa has abundant solar energy resources,but due to its high altitude and extremely cold winter,illumination and indoor thermal comfort are the key indicators affecting the indoor environmental quality of Lhasa residences,and the size of external window shading components has a significant impact on both of them.At present,there are few studies on the shading components of traditional Tibetan houses,and there is a lack of quantitative analysis.Taking illuminance and indoor thermal comfort as the comprehensive optimisation objectives,this paper uses genetic algorithm to calculate the size of the shading components in the typical space of traditional houses in Lhasa,and summarises the suitable size range of shading components for Lhasa dwellings,so as to provide a scientific basis for the improvement of the light and heat environment of Lhasa dwellings.
