摘要
建筑设计参数对建筑运营过程中的能耗和成本有着重要的影响,而新疆冬季严寒且漫长,使得该地区建筑能耗及运营费用高于其他地区.因此,本文利用离差最大化法结合正交试验设计,以某教学建筑为例,考察了在新疆4 个热工分区的典型城市气象条件下,包括中庭面积比、天窗面积比、不同立面的窗墙比、外围护保温层厚度、外窗类型等 8 个设计参数对建筑能耗和全局成本的影响,并通过综合考虑建筑能耗和全局成本目标,确定最佳的建筑设计方案.研究结果表明,在 4 个典型城市气象条件下,最佳设计方案可以实现建筑节能 10.47%～13.48%,全局成本降低 32.62～62.91 元/m2.研究有助于设计者选择适用于该地区的最佳设计参数,从而实现建筑的节能目标.
Abstract
Building design parameters have an important impacton energy consumption and cost during building operation,and the severe and long winter in Xinjiang makes thebuilding energy consumption and operation cost in this region higher than other regions.Therefore,in this paper,using the deviation maximization method combined with orthogonal experimental design,the impacts of eight design parameters,including court area ratio,skylight area ratio,window-to-wall ratio of different elevations,thickness of perimeter insulation,and type of external windows,on building energy consumption and global cost are examined under typical urban meteorological conditions in four thermal subregions of Xinjiang as an example of a teaching building.The optimal building design solution is determined by integrating the building energy consumption and global cost objectives.The results of the study show that the optimal design scheme can achieve building energy savings of 10.47%to 13.48%and global cost reduction of RMB 32.62 Yuan/m2 to RMB 62.91 Yuan/m2 under the meteorological conditions of four typical cities.The study helps designers to select the optimal design parameters applicable to the region,thus realizing the energy-saving goals of the building.
