高层办公建筑能耗影响因素的研究

Investigation of Influencing Factors of Energy Consumption in High-rise Office Building

运用动态能耗模拟软件eQUEST建立了长沙某高层办公建筑的能耗模型,得到不同建筑及设备条件下的全年建筑能耗。利用正交试验法分析得出建筑长宽比、窗墙比、外窗类型等能耗影响因素的重要程度。研究结果表明,室内设定温度、设备和照明功率密度、外窗类型是影响夏热冬冷地区高层办公建筑能耗的显著因素。

A building energy consumption analysis model for high-rise office building in Changsha is established on the basis of the dynamic energy consumption simulation software eQUEST to get the total building energy consumption under the condition of different buildings and equipment. Orthogonal test design theory is used to rank the energy consumption influencing factors, such as the building aspect ratio, window wall ratio, external window types and other factors in order of importance. The results show that the indoor setting temperature, equipment and lighting power density, external window types are significant factors of the high-rise office buildings in the hot summer and cold winter area.
