喀什传统民居与新式民居夏季热环境对比研究

A comparative study of summer thermal environment between traditional and modern residential buildings in Kashgar

为了解干热气候下喀什民居的夏季热环境状况,选取典型喀什传统民居和新式民居进行现场热环境实测,对比分析传统民居和新式民居室内外热环境差异及其原因,提出针对喀什新式民居的热环境改善建议。研究结果表明:1)喀什传统民居的夏季热环境整体上优于新式民居,庭院界面半开敞设计利于改善庭院内热环境,半地下室空间起到明显降温作用;2)新式民居朝外街开口不利于夏季热环境,围护结构热工性能不如传统民居。研究结果为喀什民居的热环境改善和气候适应性设计提供科学依据。

In order to understand the summer thermal environment of residential buildings in Kashgar in the hot-arid climate, typical traditional and modern residential buildings were selected for thermal environment field measurement. The differences and causes of indoor and outdoor thermal environment between traditional and modern residential buildings were compared and analyzed, and suggestions were put forward for improving the thermal environment of modern residential buildings in Kashgar. The results show that: 1) The summer thermal environment of traditional residential buildings in Kashgar is better than that of the modern buildings;the semi-open design of the courtyard interface is conducive to improving the thermal environment in the courtyard, and the semi-basement space has a significant cooling effect. 2) The opening of the modern residential buildings towards the outer street is not conducive to the thermal environment in summer, and the thermal performance of the envelope is not as good as that of the traditional residential buildings. The research results provide a scientific basis for the thermal environment improvement and climate responsive design of residential buildings in Kashgar.
