Study On Building Electrical Energy-Saving

With the rapid development of China’s economy, the energy shortage problem is more prominent, how to save energy and improve energy efficiency will be related to the sustainable development of China’s economy. With the sustained and stable development of China’s building industry, building energy waste is growing, but for the building, whether it is electrical equipment or lighting systems, there is a huge potential for energy savings. Therefore, the research of building electrical energy-saving is very important.This paper firstly analyzes the background and significance of the building electrical energy-saving, raise the problems and principles to be followed in the current building electrical energy-saving. Then, on the basic of the domestic and abroad research on the major energy-saving measures for the building electrical, we can get the specific technology solutions. Finally, analyze the building energy-saving by a practical example.The specific technology solutions of building electrical energy-saving mainly include:(1) Distribution transformers energy-saving technology solutions:choose the transformer model reasonably, optimize the transformer operation, distribute the transformer load economically.(2) Lines energy-saving technology solutions:choose the conductor section reasonably, reduce the line length.(3) Lighting system energy-saving technology solutions:on the basis of satisfying the power requirements, configure light reasonably, adjust the factors that influencing the lighting system of the building electrical, choose the high efficiency energy-saving lamps and accessories, choosing the ballasts reasonably, optimize the manner of lighting control and so on.
