基于热舒适改善的陕南乡村民居被动式建筑设计策略

Rural residence passive design strategies in Southern Shaanxi based on improving thermal comfort

对陕南乡村民居建筑的围护结构特点与室内热状况进行实地调查,结果显示,乡村建筑由于缺乏科学设计,围护结构热工性能差、建筑能耗高、室内热环境不理想等问题尤为突出。结合陕南气候条件,利用Ecotect软件分析各种被动式设计手段对室内热舒适的影响,以当地的典型砖混民居为例,对比分析了采用被动式设计技术前后的室内热环境变化,结果表明,该地区乡村民居采用适宜性被动式设计技术可有效提高室内热环境质量,本研究可为陕南及同类地区的乡村民居设计提供理论参考。

The field survey is made of building envelope characteristics and indoor thermal conditions of residence in southern Shaanxi. The results show that owing to lack of scientific design in the current rural buildings there are such protruding problems as poor thermal performance of building envelope, high energy consumption, undesirable indoor thermal environment etc. Combined with the climate condition in southern Shaanxi, Ecotect software is used to analyze various passive design methods on the influence of indoor thermal comfort. With the local typical brickand-concrete construction of residence as an example, a comparative analysis is made of the indoor thermal environment changes by adopting the passive design strategies before and after. The results show that the quality of indoor thermal environment is improved obviously after adopting the suitable passive design strategies and accordingly the research will provide reference for rural residential design in Southern Shaanxi and similar areas.
