摘要:

以广州市一栋办公楼为研究对象,采用正交试验方法研究了外遮阳、自然通风、自然采光、外墙节能、外窗节能等5种被动式节能技术对其冷负荷与建筑能耗影响的显著性。研究结果表明:5种被动式节能技术对该办公楼的冷负荷与建筑能耗均有显著影响,但影响的显著性排序不同;对冷负荷影响最显著的是外遮阳技术,而对建筑能耗影响最显著的是自然采光技术;显著性排最后的均为外墙节能技术。

Abstract:

Taking an office building in Guangzhou as a research object, with the orthogonal experimental method, studies the significance impacts of five passive energy saving technologies, including external shading, natural ventilation, day lighting, envelope energy saving and external window energy saving. The results show that all of the five passive energy saving technologies have significant impacts on cooling load and building energy consumption, but the significance sequence is different. The external shading is the most significant factor for cooling load, while day lighting is the most significant factor for building energy consumption. Envelope energy saving is the least significant factor for both the cooling load and building energy consumption.
