RESEARCH ON TARGET VALUE OF AUXILIARY ENERGY CONSUMPTION IN PASSIVE ULTRA-LOW ENERGY CONSUMPTION BUILDING DESIGN IN COLD ZONE
-
摘要: 目前,被动式超低能耗建筑标准适用于设计后评价,缺乏针对设计前期形体生成阶段的能耗目标值。以寒冷地区典型居住建筑为研究对象,对形体生成阶段的被动超低建筑能耗目标进行研究。通过实地调研和数据分析,建立寒冷地区被动式超低能耗居住建筑典型模型,确定影响能耗变量的取值范围,并采用正交工况设计和能耗模拟相结合的方式,推导居住建筑形体生成阶段的采暖需求目标值。提出的能耗目标值计算方法可有效控制被动式建筑能耗、辅助超低能耗建筑设计,并为其他地区以及其他建筑类型的超低能耗建筑设计理念提供理论支撑和设计参考。Abstract: At present, the passive ultra-low energy consumption building standard is suitable for post-design evaluation, and it lacks the energy consumption target value for the form generation stage in the early stage of design. Taking typical residential buildings in cold zone as the research object, the passive ultra-low building energy consumption target in the form generation stage was studied. Through on-the-spot investigation and data analysis, the typical model of passive ultra-low energy consumption residential buildings in cold zone was established, and the value range of influencing energy consumption variables was determined. The heating demand target value of residential buildings in the shape generation stage was deduced by combining orthogonal design and energy consumption simulation. The proposed calculation method of energy consumption target value could effectively control passive building energy consumption, assist ultra-low energy consumption building design, and provide theoretical support and design reference for ultra-low energy consumption building design concepts in other regions and other building types.
