The emerging intelligent building is a new cross-disciplinary set of multi-disciplines that integrates modern computer technology, network communication technology, modern automatic control technology, and electrical technology. Building electrical is obviously the foundation and mother of intelligent building. Intelligent building is only an inevitable trend for building electrical adapting to the development of modern knowledge and information society.
The advantages of building intelligence
Energy saving
Taking a modern commercial building as an example, its air-conditioning and lighting systems consume a lot of energy, which accounts for about 70% of the total energy consumption of buildings. In order to meet the user's requirements for the environment, intelligent buildings should use their "intelligence" to make use of natural light and atmospheric cooling (or heat) as much as possible to regulate the indoor environment in order to minimize energy consumption. According to the procedures determined in advance on the calendar, the distinction between "work" and "non-work" time, the implementation of different standards of indoor environment automatic control, automatically reduce the indoor illumination and temperature and humidity control standards after work, has become the basic function of intelligent buildings. Using the latest technologies in air conditioning and control industries, maximizing energy savings is one of the key features of smart buildings, and its economy is also an important reason for the rapid promotion of such buildings.
2. Safe, comfortable and convenient environment
Intelligent buildings first ensure a high degree of safety for people, finances and property, and have the ability to respond quickly to disasters and emergencies. Intelligent buildings provide indoor suitable temperature, humidity and fresh air, as well as multimedia audio and video systems, decorative lighting, and public environmental background music, which can greatly improve people's work, study and quality of life. Intelligent buildings provide people with an efficient and convenient work, study and living environment through modern communication means such as telephones, televisions, computer local area networks and the Internet, and various network-based business office automation systems.
3. Save labor costs for operation and maintenance
According to the statistics of the American Building Association, the life cycle of a building is 60 years. The cost of maintenance and operation in the 60 years after its commissioning is about 3 times the construction cost. According to statistics from Japan, building management fees, utility bills, gas charges, maintenance of machinery and equipment, and lifts account for about 60% of the entire building's operating expenses; and its cost will increase at a rate of 4% per year. Therefore, relying on the intelligent management function of the intelligent system, it can play its role to reduce the maintenance cost of electromechanical equipment. At the same time, due to the high degree of integration of the system, the operation and management of the system is also highly centralized, and the personnel arrangements are more reasonable, making the labor cost to a minimum. .
Intelligent buildings have other intelligent technologies than traditional buildings, such as: security protection technology, communication network technology, system integration technology, intelligence of residential communities, and intelligence of office buildings. These technologies are to let the building buildings have a feeling and a brain, the design is more humane, and people can get a better experience in life and work.
