Compared with traditional buildings, intelligent buildings have incomparable advantages. Through advanced technical means, anyone in the building can get comfortable, safe and efficient office environment and rich, intelligent and personalized information services at any time and in any relevant place.

Building equipment automation system can realize the rational use of equipment, save energy and manpower, ensure the safe operation of equipment, strengthen the modern management of building mechanical and electrical equipment and improve economic benefits.

Intelligent building is an advanced stage of architectural development. Due to the development of intelligent technology, there is no unified definition of intelligent building at present, and Europe, the United States, Japan, Singapore and the International Society of Intelligent Engineering have different formulations. Taking Japanese standards as an example, the definition of intelligent building by Building Intelligence Branch of Japan Electrical Machinery Industry Association is: integrating the most advanced technologies in computer, information and communication. Make the power, air conditioning, lighting, disaster prevention, anti-theft and transportation equipment in the building work in harmony, and realize building automation (BA), communication automation (CA), office automation (OA), security automation system (SAS) and fire automation system (FAS). A building that combines these five functions with the Structured Integrated Wiring System (SCS) and the Structured Integrated Network System (SNS).
