寒冷地区近零能耗建筑中被动式技术的节 能潜力研究-以大连独栋别墅为例 1 大连理工大学 周文倩 ，李祥立，端木琳 摘 要：中国建筑能耗在全社会终端能耗量中占比达三成，所以建筑节能工作势在必 行。近零能耗建筑作为建筑节能的初步目标和方向，需要多种技术的结合与创新，其中被动 式技术是实现建筑近零能耗必不可少的设计手段，但各技术对节能的贡献率有待进一步的研 究。本文以大连为例，利用Weather Tool 软件对被动式技术在寒冷地区的适用性进行分析， 比较各技术的节能潜力。再根据建筑模型参数的设定，利用EnergyPlus 软件对建筑能耗进 行模拟，明确了不同被动式技术的节能率，最后提出了适用于以大连地区为典型的寒冷地区 近零能耗建筑的被动式节能技术措施。 关键词：寒冷地区；近零能耗建筑；被动式技术；节能潜力 Abstract ：The building energy consumption in China accounts for 30% of the total energy consumption of the entire society, so it is imperative for building energy-saving work. Net-zero- energy buildings as the preliminary building energy-saving goals and directions, need the combination of various technologies and innovation, including passive technology which is an essential means of achieving net-zero-energy design of buildings, but the contribution of various technologies to energy saving rate remains to be further studied This paper took the city Dalian as an example and the Weather Tool software was chosen to analyze the applicability of passive technologies in cold regions, and to compare their energy-saving potential. After setting the parameters of the building model, EnergyPlus was used to simulate the energy consumption, and the energy savings under different passive technologies were clarified. Finally, the passive energy- saving technology measures were proposed which were applicable to the near-zero-energy buildings in Dalian, a typical city of cold regions. Keywords ：cold regions; near-zero-energy buildings; passive technology; energy-saving potential 引言 上世纪70 年代至今，被动式技术在不断的探讨和研究中日趋成熟。国外“被动房”技 术起步早且发展迅速，尤其是德国的被动房技术体系，在国际上处于领先地位。Eike Musal[1] 等人对欧美等国的282 栋零能耗示范建筑分析发现，高效保温技术、太阳能利用、建筑遮阳 1 作者简介：周文倩，女，1993 年5 月，在读硕士，辽宁省大连市大连理工大学综合实验4 号楼427 ， 116023，wqzhou@ ，河南省辉县市人，居住建筑自然通风量 预测模型的研究 基金项目：国家重点研发计划近项目“近零能耗建筑技术体系及关键技术开发” （2017YFC0702600 ）
