"The green standard is not perfect, and the return on investment is not quantified, resulting in poor energy efficiency in buildings." Yan Baolong, director of market information of Honeywell Automation Control System Group in Greater China, said when analyzing the reasons why the implementation of green buildings is not in place. The development trend of intelligent building industry The future development of intelligent building will be mainly reflected in the development of intelligent building technology and related technologies, the development of intelligent building application fields and the sustainable development of intelligent building and related industries. Analysis of Intelligent Building Market Pattern From a regional perspective, East China, South China and North China are the most important intelligent building markets in China, and East China accounts for about 1/4 of the national intelligent building market. We predict that in 20 14-20 18, the above three areas will still be the main intelligent building market. However, with the development of regional economy moving westward, the market scale of building intelligence in Central China, Northeast China and Southwest China will gradually expand. Chart The regional distribution of intelligent buildings in China The development trend of intelligent building industry in the future will be mainly reflected in the development of intelligent building technology and related technologies, the development of intelligent building application fields and the sustainable development of intelligent building and related industries. (1) Intelligent building technology and related technologies will develop at a faster speed. The development of IT technology such as electronic technology, automation technology, communication technology, computer technology and other technologies directly related to the construction industry, such as new materials and new equipment, provides all-round technical support for the development of intelligent building technology. The achievements and foreseeable development prospects of intelligent building attract a large number of outstanding talents and provide rich human resources for the development of intelligent building technology. Take the domestic situation as an example. When intelligent building technology first entered China, there were only a handful of technicians engaged in related work, and experienced professionals were even more scarce. After years of development, the number of professional and technical personnel in intelligent building and related technologies and industries is not the same as that of that year, and a considerable number of professional institutions engaged in intelligent building research have been established; Many colleges and universities offer courses related to intelligent building, and some universities offer related majors to train professionals from junior college to graduate students, so as to provide reliable human resources guarantee for the sustainable development of intelligent building technology. Due to the amazing development speed and good development prospect of intelligent building, it attracts a lot of funds and provides reliable financial guarantee for the research and development of new technologies and new products. At the end of 1990s, the famous Siemens company entered the intelligent building industry by acquiring the technology and products of Landis company with mature technology, great popularity and high market share, and soon became one of the internationally famous suppliers of technology and products, which is a typical example. (II) Intelligent Building and Its Sustainable Development The concept of "intelligent building" comes from "intelligent building", and the early intelligent building mainly refers to "building automation system". With the increasing importance of computer network system, office automation system and modern communication system in modern architecture, a new concept of intelligent building marked with "3A" is naturally formed. With the progress and development of the times, the scope of "intelligent building" is constantly developing and enriching. Due to the wide application of intelligent building technology in residential buildings, residential quarters with intelligent, information and digital functions are constantly emerging for people to live in. Intelligent residential quarters have dynamically changed the original meaning of "intelligent building" and become another important part of "intelligent building". The construction and development of intelligent housing (residential area) not only reflects a country's economic strength, but also is one of the comprehensive signs of a country's scientific and technological level, and also becomes the inevitable trend of housing construction and development in human society. Today, human society has entered 2 1 century. In modern cities, people have built more and more intelligent buildings (groups) and modern residential quarters with the characteristics of "intelligent buildings". Although they have established their own unique comprehensive "information systems", from the perspective of the whole city, they are still only "information islands" or "information units" with complete functions. How to organically link these information islands, give full play to their functions and functions, and then push the whole city towards modernization, informationization and intelligence, the concept of "digital city" came into being.
In a sense, we can think that "digital city" is a special extension of the concept of "intelligent building". It can be imagined that all intelligent buildings, such as houses, communities, hospitals, banks, schools, supermarkets and shopping centers, will be connected through the information network, and the intelligent buildings, intelligent houses or wireless city based on the information platform of "Digital City" will be very different from modern intelligent buildings, intelligent houses or wireless city. These foreseeable prospects indicate that "intelligent building" has an extremely broad development field. (III) Sustainable development of intelligent buildings and related industries The development of intelligent buildings in China in recent years has promoted the rapid development of related industries and has become an important part of high-tech industries. The rapid development of intelligent building technology and the continuous expansion of intelligent building field will make the scale of related industries grow and the development speed accelerate. In recent years, the expanding industrial team and the formed industrial scale are examples. The development of intelligent building also promotes the rapid development of intelligent technology of building equipment. In recent years, the control systems of refrigeration units, elevators, power distribution, lighting and other systems and equipment are becoming more and more intelligent, which provides strong technical support for the improvement of intelligent building functions. On the other hand, it also promotes the continuous improvement of product technology level and product upgrading in related industries. Intelligent building and its related high-tech industries can develop at a high speed in the world, which is beyond personal will. Its inherent advantages, especially its huge economic benefits, make it full of vitality and in the ascendant, and will become one of the main high-tech industries in the 2 1 century. Prediction and Analysis of Intelligent Building Market Scale Investment Consultant pointed out in "Report on In-depth Investigation and Investment Prospect Prediction of Intelligent Building Industry under Construction in the 13th Five-Year Plan of China" that the market scale of intelligent building in China will increase from 427 million US dollars in 20 12 to 104 billion US dollars in 2020, which provides a broad development space for advanced building technologies and services. The future will present the scene of the rapid development of the new building market in Asia, which will also promote the rapid development of intelligent buildings. By 2030, Asia's energy consumption will account for 45% of the world's total energy consumption, among which buildings will be the major consumers of electricity. The rapid development of urbanization in Asia will reduce the impact on climate change through the development of intelligent buildings. In Asia, the concept of intelligent building includes green building and intelligent building. In this regard, there are many key evaluation criteria for green and intelligent buildings. In many Asian countries, smart cities have achieved a sustainable urban development model. Smart cities include many contents, mainly the infrastructure of communication technology (ICT), and ecological, sustainable, green and low-carbon cities, which interpret different green elements. Japan and South Korea have two smart cities, Fujisawa and Matsushima respectively. There are 36 smart cities under construction in China. By 2050, Singapore will become a smart country, with Hisquin as its flagship smart city. Delhi and Mumbai industrial belts will become smart cities in India in the future. China is investing 250 billion yuan to build Tianjin into a low-carbon demonstration city. Smart cities provide a lot of business opportunities for communication and information technology, software, electronic hardware products and low-carbon industries. At present, communication information technology and software enterprises are growing in the smart city market. System and service providers establish cooperative relations with the government and become independent investors. Apart from Japan, zero-energy building is more of a concept than a higher goal in many Asian countries. Generally, zero-energy buildings are used as demonstrations of various low-carbon technology applications. In developing countries, the key of smart grid lies in upgrading the existing power grid infrastructure, while in developed countries, it is related to the power grid communication system. For China and India, it is urgent to upgrade the power grid to meet the increasing power demand. Different countries are at different stages of smart grid development. China municipal government promised to invest 654.38+05 billion dollars to upgrade the power grid. Many other Asian countries are also investing in smart grids. The electricity market in Asian countries is still a state monopoly, but Australia has completely liberalized its control. In developing countries, manual demand management (DSM) is generally used to solve the power shortage problem. Automated Management Reflection (AutoDM) is in its infancy in Asia, but the existing DSM market provides business opportunities for the future development of AutoDM. Future Development Direction of Intelligent Building Projects According to the report "In-depth Investigation and Investment Prospect Forecast of Intelligent Building Industry under Construction in China in the 13th Five-Year Plan", the intelligent building industry has a high degree of prosperity, and will develop in three dimensions in the future: (1) Smart grid and intelligent building will gradually merge and develop in the direction of green energy saving. From the development history and experience of foreign countries, the integration of smart grid and intelligent building is a trend, and the core is to provide more energy-saving buildings. It is not only conducive to creating a sustainable development environment, but also conducive to giving users a practical energy-saving experience, enjoying the real differential electricity price brought by energy saving, reducing electricity expenses and achieving better economic benefits. This is also the core of all-round marketing of intelligent buildings. (2) Intelligent buildings gradually extend from commercial buildings to social public buildings and residences. In the United States, energy saving based on intelligent buildings has expanded from commercial buildings to social public buildings. (MUSH mainly refers to municipal institutions (municipal government and state government), schools (including universities), hospitals, etc. ). China is mainly concentrated in the field of commercial buildings. In the future, with the continuous promotion of energy conservation and emission reduction in China, the scope of energy conservation will gradually expand to the field of social public buildings. At present, the business of companies in the industry has begun to penetrate into hospitals, exhibitions and exhibitions. With the continuous development and maturity of ZigBee, WIFI and other wireless network technologies, it is possible to connect the home wirelessly, and the cost is lower than that of wired, which promotes a new wave of smart home marketing. (3) Domestic equipment developers extend the industrial chain and gradually participate in providing comprehensive solutions for the industry. The leading companies in foreign industries are equipment suppliers, while the companies that provide solutions and energy services have a small market share. Due to the gap between China and foreign countries in equipment technology research and development, China only focuses on the integration of smart devices, and most of them still use foreign devices. With China's technology gradually achieving a wider range of independent innovation, such as Huawei, Tongfang, Zhejiang Kong Zhong, etc., they have certain advantages in equipment research and development, and will extend the industrial chain and cut into specific industry solutions in the future. At present, the main business of Tongfang Taide, a wholly-owned subsidiary of Tongfang Co., Ltd., is R&D and sales of building automation equipment and professional solutions for building energy conservation. The same is true of Zhejiang Kong Zhong and Huawei. In the future, the mainstream integrated solution providers in the industry will face more intense market competition. Integrated solution providers strengthen their own services and improve the competitiveness of the industry. Based on all aspects of communication and information technology (ICT), energy and low-carbon technology, intelligent buildings are integrated to form smart cities and smart grids. Government, end users and building owners are the driving forces for the development of intelligent and green buildings. Intelligent buildings are developing continuously in smart cities, and green buildings will also become the main trend of new buildings in Asia. In the future, by 2020, Asia's construction market share will account for 43% of the world, and China, Indian, Japanese and Indonesian will be the fastest-growing areas of intelligent building industry. By 2020, driven by urbanization, smart cities and the government's carbon reduction targets, the market size of intelligent buildings in Asia will reach 654.38+0.4 billion US dollars.
