电能是我们运用最为广泛的能源,电能的节约对我们整个社会来说都有积极的意义。建筑电气节能的设计思路也得到了社会的广泛关注。相对于整个能耗总量来说,建筑能耗占有很大比例。本文以电气节能为基础,详细的介绍了建筑电气节能的设计要点,根据实践得来的经验,探讨相应的配电、照明系统,为以后的工作提供一定的参考价值。 Electricity is our most widely used energy source, and saving electricity has a positive effect on our society as a whole. The design idea of ​​electrical energy-saving building has also been widely concerned by society. Building energy consumption accounts for a large proportion of total energy consumption. Based on the electrical energy saving, this paper introduces the design essentials of the building electrical energy saving in detail, and based on the experience gained from practice, explores the corresponding power distribution and lighting system to provide some reference value for future work.
