Building electrical design includes high voltage and weak electrical design. The high voltage design is described in chapter 2, chapter 3 and chapter 5. And the weak electric design are described in chapter 6 . The whole article is summarized in chapter 1. The design of the power supply system is elaborated in chapter 2. The classification of load and load power supply measures are introduced in power supply system. Equipments are selected and checked according the load calculation and the calculation of shortcircuit current. The general lighting and emergency lighting design is described in chapter 3. Then intensity of illumination is calibrated, and two kinds of intelligent lighting control methods are briefly described. The design content and basis of automatic fire alarm and fire linkage is introduced in chapter 4. The design of lightning proof and grounding method is discribed in chapter 5. At last, the weak electric system design is simply introduced. A kind of intelligent parking management system is generally introduced. This design pleted 22 drawings, for power distribution part of 6, lighting part of 9, fire control section 6 painting, another for drawing lists, a legend. The electrical design of department store is a lively practice, which not only integrates use of knowledge, but also bines the theory with practice. The practice exercises independently analysis and the ability of solving building electrical design problems, which lays a solid foundation for work in the future.
