【摘要】：通过对严寒地区某公寓室内热环境和围护结构热损耗的测试,研究既有公寓建筑能耗现状和节能降耗策略,并利用Energy Plus分析不同围护结构改造措施对建筑采暖能耗的影响,本文首次提出将石蜡基相变材料用于外墙体抹灰的改良策略中.结果表明:严寒地区既有公寓具有很大的节能潜力,墙体中使用石蜡基相变材料节能效果显著,坡屋面较倒置屋面更节能;并得到适宜该地区的玻璃窗形式,为严寒地区公寓式建筑围护结构的节能改造及设计提供参考依据.
[Abstract]:Based on the test of indoor thermal environment and heat loss of enclosure structure in an apartment in severe cold area, the present situation of energy consumption and energy saving and consumption reduction strategy of existing apartment buildings are studied. Energy Plus is used to analyze the influence of different retrofit measures on building heating energy consumption. In this paper, the application of paraffin-based phase-change materials to the improvement of outer wall plastering is proposed for the first time. The results show that there is a great potential for energy saving in existing apartments in severe cold areas, and the effect of using paraffin-based phase-change materials in walls is remarkable. The slope roof is more energy efficient than the inverted roof. The form of glass window suitable for this area is obtained, which provides a reference for the energy-saving reconstruction and design of the building enclosure structure in severe cold area.

【正文快照】： 自1999年中国实行高校扩招至今,学生公寓建设规模已经超过了过去几十年的总数.在中国北方地区最突出的建筑用能为冬季采暖[1],但由于缺乏科学的理论指导,使得很多既有学生公寓的建筑采暖能耗偏高,已远远超过中国当前的节能要求.建筑的节能与可持续发展已经成为当今建筑发展的
