随着经济的发展和人们生活水准的提高民用建筑成为了建筑耗电的大户,这就对民用建筑电气的优化设计即对电气节能的设计提出了更高的要求。近几年民用建筑电气节能的重要意义已逐步受到人们的重视。现就电气节能设计应遵循的原则,从供配电系统设计、合理使用电动机、功率因数补偿、照明节能、可再生能源利用、能源管理系统、高效节能光源、灯具的选用等方面,论述了建筑电气节能的合理应用。 With the development of economy and improvement of people’s living standards, civil buildings have become the major consumers in building electricity consumption. This puts forward higher requirements on the optimization of electrical design of civil buildings, that is, the design of electrical energy-saving. In recent years, the importance of electrical energy-saving civil buildings has gradually been people’s attention. Now on the principle of electrical energy-saving design should follow, from the power supply and distribution system design, rational use of motor, power factor compensation, energy-saving lighting, renewable energy use, energy management systems, energy efficient light sources, Reasonable application of electrical energy-saving.
