摘要
通过对湘北地区某乡村砖混结构民居的围护结构特点以及室内热环境状况进行调研,发现该类建筑存在围护结构热工性能差、建筑能耗高、室内热环境质量低等问题。针对上述问题,结合夏热冬冷地区的地域气候特点,提出了合理选择建筑朝向、改善围护结构热工性能、控制窗墙比以及自然通风等适应性的被动式建筑设计优化方案,利用Ecotect软件分析了上述优化策略对室内热环境改善的影响。通过正交试验方法设计试验方案,并计算分析了9组方案在全年典型日的P M V值,得到湘北民居最优设计方案。
Investigated and researched the retaining structure of a rural residential brick concrete house in the north of Hunan and the indoor thermal environment conditions, and found some problems such as poor thermal performance of house envelope, high energy consumption, low quality of indoor thermal environment, etc. Aiming at the problems and combining with the regional climate characteristics in hot summer and cold winter area proposed passive-house design optimal scheme of reasonably selecting house orientation, improving retaining structure thermal performance, controlling window wall ratio and natural ventilation, etc. Analyzed the influence of the optimization strategy on the indoor thermal environment improvement by Ecotect software. Designed the experiment scheme by the orthogonal testing method, calculated and analyzed the PMV values of the typical day of the year of nine schemes, and obtains the optimal residential design of north Hunan.
