Intelligent buildings are built on the platform of buildings, with communication technology as the mainstay and system integration as the method, which organically combines computer technology, network technology, automatic control technology, software engineering technology and architectural art design to break through information barriers among isolated systems and make buildings an intelligence of information interchange. The main body realizes the intelligent management of buildings and the effective utilization of information resources.
With the continuous development of the real estate industry in China, the intelligent building market has grown rapidly, and the concept of building intelligence has become more and more popular. With the rapid development of new urbanization, the continuous expansion of building intelligence application subdivision and the strong support of national industrial policy, building intelligence market has become a new gold digging ground.
Intelligent building market has great potential in China. At present, the demand of intelligent building market in China mainly consists of two parts: one is the direct application of intelligent technology in new buildings, the other is the intelligent transformation of existing buildings. Among the existing buildings, about 3% (average transformation period is 30 years) of residential buildings and 6% (average transformation period is 15 years) of industrial and public buildings will be intellectualized every year. According to the average transformation cost of 80 yuan per square meter of residential buildings and 150 yuan of public buildings, the intellectualized transformation scale of existing buildings will reach 380 billion yuan and CAGR will reach 9% by 2018. Among them, the largest proportion of public buildings is 38%.
Based on the completed area of various types of buildings announced by the Ministry of Housing and Construction in 2012, assuming that the completed area of residential buildings increased by 11% annually, the annual growth of factory buildings and warehouses by 8% and the annual growth of office and commercial service buildings by 15%, the new building area in 2018 will be close to 6.8 billion square meters and CAGR 11.4%. In 2012, China's smart building construction accounted for about 30% of the new buildings, while in the same period, the proportion of newly built smart houses was 70% in the United States and 60% in Japan. Assuming that the proportion increases by 3% annually in the forecast period, the smart building area will increase from 1.1 billion square meters in 2012 to 3.3 billion square meters in 2018.
Building intellectualization has outstanding advantages in low carbon and energy saving, while bringing more comfortable experience to people's lives. China's new building area is about 2 billion square meters every year. In addition to the government's standardized and scientific guidance on building intelligence construction, the industry generally looks forward to the development of building intelligence. According to the analysis and estimation of "Research Report on Market Deep Analysis and Investment Strategy of Building Intelligence Industry" issued by Prospective Industry Research Institute, the total scale of building intelligentization market will reach 1.06 trillion yuan by 2018 and 15% by 2014-2018, of which the incremental scale of building intelligence accounts for about 64%.
