摘　　要：目的 研究严寒地区某近零能耗办公建筑负荷特性,以便逐步完善近零能耗办公建筑的性能化设计方案,达到近零能耗建筑预定的性能目标。方法 以处于设计阶段的某近零能耗办公建筑为研究对象,使用DesignBuilder软件对参照建筑与目标建筑分别进行能耗模拟,并对结果进行分析比较。结果 目标建筑全年累计热负荷指标为15.96 (kW·h)/m^(2),全年累计冷负荷指标为19.94 (kW·h)/m^(2);目标建筑与65%的节能建筑相比,累计总负荷指标降低45.86%,热负荷指标降低64.34%,冷负荷指标降低5.89%。结论 近零能耗办公建筑夏季冷负荷指标略高于冬季热负荷指标,各项节能技术对降低热负荷指标及累计总负荷指标均有促进作用,内部热扰和外窗太阳得热对冷热负荷指标影响应予以重视。The load characteristics of a nearly zero energy office building in severe cold area were studied in order to gradually improve the performance-based design,and to achieve the performance goals for nearly zero energy buildings.A nearly zero energy office building in the design stage taken as the research object,the energy consumption of the reference building and the target building were simulated using DesignBuilder software.The simulation results were analyzed and compared.The cumulative annual heating load index of the target building is 15.96(kW·h)/m^(2) and the cumulative annual cooling load index is 19.94(kW·h)/m^(2).Compared with the 65%energy efficient building,the cumulative total load index of the target building is reduced by 45.86%.The heating load of the target building is reduced by 64.34%and the cooling load of the target building is reduced by 5.89%.So in the summer the cooling load of the nearly zero energy office building in Shenyang is slightly higher than the heat load in the winter.Each energy-saving technology has a promoting effect on reducing the heat load and the cumulative total load index.The influence of internal heat disturbances and solar heat from external windows on the cold and heat load index should be given attention.
