极端干热气候乡土建筑用能模式与能耗强度

Energy Consumption Modes and Energy Intensity of Vernacular Buildings in Dry-hot Climate

农村建筑是我国建筑行业开展清洁节能和低碳减排关注的重要领域,在以吐鲁番为代表的极端干热气候区,农村建筑采暖、制冷负荷大,节能形势严峻。以乡土建筑“部分空间、部分时段”的节能型用能方式为前提,通过文献研究归纳吐鲁番乡土建筑特征,现场调查乡土建筑围护结构、用能模式、能耗强度和居民空间行为的相关信息数据,提炼节能型建筑用能模式,提出适宜的环境与节能优化方案,并给出能耗强度限值作为评价指标。为后续吐鲁番地区乡土建筑能耗定额标准的研究和制定提供参考,对吐鲁番地区农村建筑能耗总量的控制具有重要意义,并且丰富了极端干热地区农村建筑的能耗研究。

Rural buildings are an important area of concern for clean energy conservation and lowcarbon emission reduction in domestic construction industry.In extreme dry-hot climate areas represented by Turpan,rural buildings have large heating and cooling loads,and the energy-saving situation is severe.According to the premise of the energy-saving consumption mode of vernacular architecture in“part of space,part of time”,the characteristics of Turpan vernacular architecture are summarized through literature research,and the relevant information of vernacular building envelope,energy consumption pattern,energy consumption intensity and residents’spatial behavior is investigated on site.The energy consumption model of energy-saving buildings is refined,proposing suitable environmental and energy-saving optimization plans,and the energy consumption intensity limit as an evaluation index.This research provides a reference for the subsequent research and formulation of energy consumption quota standards for rural buildings in Turpan,which is of great significance for controlling the total energy consumption of rural buildings in Turpan,and enriching the research on energy consumption of rural buildings in extremely dry and hot areas.
