It is designed includes a calculation and design of power supply and distribution system , a design and calculation of lighting system and a design of fire alarm system. First of all, the load step of the design of power supply and distribution system is based on the properties of the building and national normative criterion, in which lighting of the walkway and antechamber, `passenger elevator, drainage pump, living pump, and the fire load are all secondary loads, while others are trigrade load. Then it obstains transformer capacity and slects proper transformer according to loading capacitance capability by using needfulcoefficient method and load index method。 and it also can use the natorietyvalue method to calculate the short –circuit current for highvoltage and low voltage of the transformer. And then check of the thermal stability and dynamic stability of che cable or bus, and check of the thermal stability and dynamic stability and breaking capability of switchgear. Second, che the design of lighting system. We must get clear on the applying functions in construction, and then calculate the illuminance of each atrial by using utilization factor. After that we can get che arrangement of the lamps and the sockets according to national normative criterion according to ―residential design codes‖ and ―Standard for Lighting Design of Buildings‖ to satisfy the requirements of illuminance uniformity of illuminance power density. Third, che the design of fire alarm system. Get clear of the fire rating of the building, and the secondary protected object must use concentrated alarm system. Lay the alarm detector in the suit position and design the linked fire control according to national normative criterion. Key words: Residential, Electrical Design, Power Supply and Distribution System, Lighting System, Fire Alarm System III 目 錄 中文摘要 ................................................................................................
