ABSTRACT
This page is about common hotel’s electricity design, including lighting system design, air-condition and motive system design, fire auto report to the police system design, defend the thunder and connect the ground system design, underground floor person defend system design .
    lighting system design: Strict design according to the standard of the building lighting’s request. Notice: economize on lighting energy, lighting control and lighting quantity, make the design humanization.
    air-condition and motive system design: Consume energy to the best limit, to the best close to the center carry.
fire auto report to the police system design: this engineering belong to two according to the grade of safety.
defend the thunder and connect the ground system design: this engineering belong to three defend the thunder building, on all sides and roof of the building place Φ12 steel of zinc regard as lightning rod, on the roof of the high building use the lightning rod for protect function. this engineering connect the ground system belong to TN-S system
defend the thunder and connect the ground system design: this engineering belong to three defend the thunder building, on all sides and roof of building place Φ12 steel of zinc regard as lightning rod, on the roof of the high building use the lightning rod for protect function. this engineering connect the ground system belong to TN-S system.    underground floor person defend system design: each fire fight device electrical allotment, install of evacuate lighting and lighting power that meet an urgent need. The person defend fire auto report to the police equipments design.
This design carries on the systematical design to that building according to the design norm strictly, its contents can well appears to construct the special features of the electricity profession and tight sex of the profession.
Key words：lighting system; fire auto report to the police system; defend the thunder and connect the ground.
Keyword：lighting system；fire auto report to the police system；defend the thunder and connect the ground system
