基于EnergyPlus的几种典型平面形状的塔式办公建筑的能耗差异分析

Energy consumption difference analysis of some typical geometry office tower based on EnergyPlus

塔式办公建筑的空调能耗占到建筑总能耗的50%～60%.建筑内部的太阳辐射得热量的多少直接影响着建筑的空调能耗,这个又与建筑外围护结构的面积、朝向及建筑的外形等有密切关系.采用EnergyPlus建筑全能耗模拟软件对圆形、正六边形、正方形、正三角形平面形状的塔式办公建筑进行的全年能耗模拟,根据模拟结果对这几种塔式办公建筑的能耗差异进行了分析.

The cooling energy consumption of office tower accounts for 50% - 60% of total building energy consumption. The solar heat gain directly impacts the cooling energy consumption of building. This has close relationship with the area of the building envelope, orientation, the building shape and so on. This paper use the EnergyPlus to simulate the build- ing annual energy consumption for each office tower whose floor shape is circular, regular hexagon, square or regular triangle. Energy consumption difference between these office towers is analyzed according to the simulation results.
