Abstract:  In the outline of the 13th Five-Year Plan of China，it is proposed to build a resource-saving and environment-friendly society. In order to carry out the development strategy of energy saving and e-mission reduction，the design of energy saving and consumption reduction should be strengthened in building electrical design. Taking the engineering design of Shabei Experimental School as an example,this paper discusses the technical measures of saving energy and reducing consumption in building electri-cal design and the energy saving design of power supply and distribution system , the energy saving design of lighting system，the new electrical equipment，photovoltaic power generation and the natural light guide tube system in basement are adopted ,and the technical measures of energy saving and consumption reduction in building electrical design are discussed. The results have achieved better energy saving effect.
