An intelligent building concept and characteristics
1.1 The concept of intelligent building
"Intelligent building" concept, was born in the early 80s of the 20th century, it is the inevitable result of the information age. With the intelligent building (also known as Intelligent Building) in the continuous application of intelligent technology and development, it is very difficult to "intelligent building" a precise definition of the next.
American Intelligent Buildings Institute (AIBI, AmericanIntelligentBuildingInstitute) definition of "intelligent building" is the structure, systems, services, operations and interrelationships of a comprehensive and integrated, and the best combination, obtained by high efficiency, high performance and high comfort building. The new definition is more general and abstract.
From a development point of view, should be emphasized that intelligent building is a multi-disciplinary, multi-technology system integration features, which refers to the use of intelligent building system integration method, the intelligent computer technology, communication technology, information technology and art of organic architecture , and through automatic monitoring equipment, information resources management and information services to users and their optimal combination of the building, which was a reasonable investment for the information needs of the community and has a safe, efficient, comfortable, convenience and flexibility Features of the building.

Intelligent building construction, also known as 3A. The advantages of intelligent building
1.2 (1) create a safe, healthy, comfortable and can improve the efficiency of the office environment.
In developed countries, people causing residents headaches or malaise, or even frequently called sick buildings "People Building Syndrome" (SickBuildingSydrome) buildings. The first intelligent building to ensure the safety and health, its fire and security systems are intelligent; its air conditioning system to monitor the content of harmful pollutants in the air, and automatically disinfected, making it "safe and healthy building." Intelligent Building of the temperature, humidity, lighting levels are to be automatically adjusted, or even control the color, background noise and smell, so people feel comfortable as at home, which can greatly increase the work efficiency.
(2) Energy Conservation To modern commercial buildings, for example, the air conditioning and lighting systems, large energy consumption, accounting for 70% of total energy consumption of buildings. To meet user requirements on the environment under the premise of intelligent building, through its "wisdom", as far as possible use of natural light and cold air (or heat) to regulate the indoor environment to minimize energy consumption. By pre-established procedures on the calendar, the distinction between "work" and "non-work" time, the implementation of the indoor environment of different standards of control, after work automatically reduce the indoor illumination and temperature and humidity control standards, have become essential for intelligent buildings function. Use air conditioning and control industries latest technology to maximize the energy savings are the main features of the intelligent building, its economy is of such construction can be an important reason for rapid promotion.
(3) to meet various user requirements in different environmental functions
Intelligent building demands of their architectural design with smart features, in addition to support 3A (or 5A) function to achieve, must be open, large-span frame structure, allows the user to quickly and easily change the function or re-use of the building planning architecture. Necessary for indoor office communications and power supply also has great flexibility, through the structured cabling system, distributed in a variety of indoor standard weak and strong electric outlet, just change the jumper cables, you can quickly change the function socket such as changing the computer program-controlled telephone interface, in some circumstances there are wireless solutions as a strong complement.
(4) modern means of communication and working conditions.
In the information age, time is money. In the intelligent building, the user through international direct dial telephone, video phone, email, video conferencing, information retrieval and statistical analysis and other means, it may be a global financial business intelligence, technology intelligence and data systems in a variety of the latest information; through the international computer communications network, at any time with world trade and other enterprises or institutions of various operations. Unprecedented speed, greatly in favor of decision-making and competition, this is the modern company or organization with competing rent or purchase the reasons for intelligent buildings.
1.3 the application of intelligent building
Abroad, the development of intelligent building has been a great start that people only recognize the need for large-scale public building intelligent, so there intelligent office buildings, office buildings and integrated building and so on, and is widely used in commercial, industrial, transportation , research, government offices and hospitals and other occasions. Today, intelligent building with its strong vitality and prominence of economic efficiency, the rapid development of the vertical and horizontal. In developed countries. Chorus of many singles and professional women no time to deal with domestic exposure to competition, to meet the needs of this social development, intelligent home emerged. Its main features are:
By automatic fire, access control and security systems to ensure security; through a central monitoring system to ensure healthy and comfortable home environment; through the computer communication network broadband technology to communications, counseling and social services, intelligent; application of multimedia and high-tech provides learning, entertainment and a good working environment and to achieve the automatic management of household. Housework fully automated, automatic cooking, utility energy-saving automatic operation and automatic billing, product advice and does not go out shopping. Learning computers, health care also depend on computers, self-air convection, sunshine, smell, Feng Yusheng and birds, people like being in nature.
2 Building Automation System (BAS) applications
2.1 Building Automation System (BAS) in the form
Building automation (BA), also known as building automation, or building automation. BA broad definition should include Fire automation (FA) and security automation (SA), Figure subsystems include the following:
(1) power system (2) lighting system (3) air conditioning and heating and cooling systems
(4) environmental monitoring and water supply and drainage system
(5) elevator system
(6) Parking Management System
