With the continuous progress of computer technology, information technology and communication technology, the concept of intelligent building began to rise in the 1980s. Intelligent building was first born in the United States, followed by the rapid development of European, Japanese and other countries and regional markets. China's intelligent building industry began to develop in the 1990s. Since the 21st century, China's economy has been rapidly improving and the real estate market has entered the construction peak, making China's intelligent building industry enter the stage of rapid development.

According to the "2018-2022 China Intelligent Building Industry Market Analysis and Research Report" released by The New Sijie Industry Research Center, from 2012 to 2017, the scale of China's intelligent building market continued to rise, the market scale in 2017 reached 264 billion yuan, a year-on-year growth of 7.0%, the scale of China's intelligent building market continued to expand. It is expected that the scale of intelligent building market in China will maintain a rapid growth rate from 2018 to 2022.

Traditional construction mainly includes civil engineering, mechanical and electrical installation and decoration decoration works three large, because of the intelligent building involves the application of electronic information technology, the high professional, thus formed the independent intelligent building system, mainly composed of information infrastructure system, information application system, building equipment monitor system, public security system, computer room engineering five subsystems. At present, the investment in building intelligent system accounts for about 5%-10% of the total investment in building engineering, and some of the investment can even reach 15%. With the continuous expansion of the construction industry, the penetration rate of China's intelligent building market continues to improve.

In terms of distribution of intelligent buildings, north China has the largest proportion of intelligent buildings, accounting for 33.4%. The second is East China, accounting for 28.5%; South China's share is 20.4 per cent. These three regions have developed economy and are the main concentration of intelligent buildings in China. With the continuous improvement of the economy, the scale of the intelligent building market in central China and northeast China is also gradually expanding, accounting for 7.9% of the market share; The share of southwest China is only 1.5%, and its development is relatively slow.

In terms of building types, intelligent buildings in China are mainly commercial buildings, office buildings and residential buildings. Commercial buildings accounted for the largest share, at 20%; Office buildings accounted for 15%, ranking second. Residential construction was third at 11%. It can be seen that the commercial office field is the main application market of intelligent buildings in China.

The scale of intelligent building market in China is expanding rapidly, and the number of enterprises in the industry is increasing. At present, there are about 1100 enterprises with intelligent building engineering contracting qualification in China. Among them, smaller and weaker enterprises occupy a larger share, and these enterprises have a lower level of design ability and do not have core competitiveness. The number of enterprises with strong strength, high research and development ability and comprehensive intelligent solutions for customers is small, and the overall market is extremely scattered.

Compared with developed countries and regions such as Europe, The United States and Japan, the penetration rate of smart buildings in China is low, and there is still a lot of room for improvement, according to an industry analyst from Siworld. However, the development of China's intelligent building industry is not sufficient, the number of powerful enterprises is small, the design level of most enterprises can not meet the needs of customers, and the industry lacks of leading pillar enterprises. With the continuous advancement of China's urbanization process and smart city strategy, the demand for intelligent buildings will continue to grow, and the intelligent building industry will usher in the phase of elimination and integration, which is conducive to the improvement of the overall competitiveness of the industry.
