摘要:本文以哈尔滨某办公建筑为例进行研究,结合有交互作用的正交试验法,应用EnergyPlus对外窗、外墙、屋面传热系数和窗墙比四个因素进行模拟实验,计算不同组合工况下的建筑能耗数值。基于计算结果,采用方差分析法,解析外围护结构传热系数和窗墙比对办公建筑采暖、制冷与总能耗影响的相关强度,进而提出严寒地区办公建筑设计策略,以及在严寒地区办公建筑节能设计、研究中,应该将建筑制冷能耗独立考虑的结论。
Taking an office building in Harbin as an example, the orthogonal test method is used in the simulate experiment. In the course of the experiment, EnergyPlus is used to study four factors, such as heat transfer coefficients about window, wall and roof and the window-wall ratio. The energy consumption of buildings under different combination conditions is calculated. Based on the results, variance analysis was used to analyze the correlation coefficient of the heat transfer coefficient and the window-wall ratio of the exterior envelope to the heating, cooling and total energy consumption of office buildings. Then the paper puts forward the design strategy of office buildings in severe cold regions and the conclusion that the building cooling energy consumption should be taken into consideration separately in the energy saving design and research of office buildings in severe cold regions.
