通过标准化的建模及模拟,对购物中心被动设计在方案阶段的节能潜力展开量化评价。以寒冷地区为例,提取出具有典型气候特征的3种购物中心标准几何模型和运行参数;并选取Grasshopper和EnergyPlus分别作为参数化建模和能耗模拟软件;同时,从场地、建筑和围护结构3个层面,总结出影响购物中心节能潜力的24个被动设计参量;最终通过模拟得到24个被动设计参量在3种标准模型中的节能潜力及排序。结果表明:入口风速、走廊空间、天窗面积比和屋面传热系数是影响寒冷地区购物中心节能潜力的4个重要设计参量,此结果可为设计师在方案阶段进行建筑优化设计提供量化指导。
In this paper, the energy saving potential of passive design for shopping centers in the early design stages is quantitatively evaluated through standardized modeling and simulation. With cold regions taken as an example, three common standard geometric models and operating parameters of shopping centers with typical climatic characteristics were extracted. Grasshopper and EnergyPlus were chosen as the standard parametric modeling software and the energy simulation software, respectively, while 24 passive design parameters from the site, building and envelope that affect the energy-saving potential of shopping centers were summarized. Finally, by simulation, the energy saving potential rankings of the 24 passive design parameters in three standard models were obtained. The result shows that the entrance wind speed, corridor space, the ratio of skylight area to roof area and roof heat transfer coefficient are four important design parameters that affect the energy saving potential of shopping centers in cold regions, providing designers with quantitative guidance for design optimization in the early design stages.
