高速公路服务区被动式超低能耗建筑实践研究
|
摘要
被动式超低能耗建筑,主要特点是不采用主动的采暖和空调形式来实现舒适的室内环境。目前,被动房在中国已有很多成功的实践,但将其应用于高速公路附属建筑尚属首次。围绕曲港高速公路博野服务区被动房项目的设计工作展开研究,对相关技术要点进行分析,主要包括外保温系统、高效节能门窗系统、外遮阳系统、新风系统、地源热泵系统5项关键技术,同时采用清华大学开发的DeST软件对建筑能耗进行逐时模拟,论证各项指标是否满足被动房设计要求,并对被动房加强参数和节能率进行分析。研究表明,博野北区被动房能够满足相关被动房设计标准,与常规节能型的公共建筑相比,博野北区被动房空调系统年累计耗冷热量能够减少80. 4%,节能效果明显。
Passive ultra-low energy consumption building,of which the main feature is not using the form of active heating and air conditioning to achieve a comfortable indoor environment. At present,the passive house in China has completed a lot of successful practice,but it is the first time to apply the passive house to the expressway service area. This paper focuses on the design work of the passive house project in Boye District of Qugang Expressway and introduces the relevant technical points. It mainly includes five key technologies,such as external insulation system,energy efficient door and window system,external shading system,fresh air system and ground source heat pump system. Meanwhile,the DeST software developed by Tsinghua University is used to simulate the building energy consumption, demonstrate whether the indicators meet the requirements of passive house design,and analyze the reinforcement parameters and energy efficiency. The study shows that the passive house of Boye North District can meet the relevant standards. Compared with the conventional energy-saving public buildings,the cumulative heating and cooling consumption of the passive air-conditioning system in Boye North District can be reduced by 80. 4% indicating significant energy saving effect.
