Smart city: building "smart" life

Guide: what is smart building? If the structure and decoration of the building are compared to a person's healthy body and beautiful appearance, the intelligent system built through various modern technologies enables the building to have a smart brain and sharp vision, feeling, hearing and touch, which can collect and process information inside and outside the building, and make appropriate responses through the intelligent system, so as to bring diversified information, safety, comfort Convenient living environment

Siemens crystal building in London covers an area of more than 6300 square meters. Compared with other similar office buildings, it can save 50% electricity and reduce 65% carbon dioxide emissions

CITIC Pacific Plaza in Shanghai saved 1.85 million kwh of energy consumption in the first year through customized energy-saving solutions

the construction of smart cities has been in full swing all over the country, and smart buildings, as one of its main construction, have sprung up one by one. What is intelligent building? If the structure and decoration of a building are compared to a person's healthy body and beautiful appearance, the intelligent system built through various modern technologies enables the building to have a smart brain and sharp vision, feeling, hearing and touch, which can collect and process information inside and outside the building, and make appropriate responses through the intelligent system to provide various information for building managers and users, Improve people's living quality and bring diversified information and a safe, comfortable and convenient living environment to residents

intelligent buildings are bringing many fundamental changes to people's production and lifestyle. In this series of processes, scientific and technological bamboo shoots are everywhere

the era of cement and mouse has come.

in western developed countries, building intelligence has already risen. In 1984, utbs company of United Technologies transformed a financial building in havoc, Connecticut, and named it city place. It mainly added computer equipment, data communication lines, program-controlled switches, etc., so that residents can get communication, word processing, e-mail, information retrieval, market inquiry and other services. At the same time, all air conditioning, water supply and drainage, power supply and distribution equipment, fire prevention and security equipment in the building are controlled by computers to achieve comprehensive automation and informatization. After the transformation, the function of the building has made a qualitative leap, and the building users have obtained an economical, comfortable, efficient and safe environment. The first intelligent building in the world was born. Since then, the global building intelligence construction has embarked on the track of rapid development

Chen long, a researcher at the Institute of automation of the Chinese Academy of Sciences, said that the development of intelligent buildings is a comprehensive reflection of the level of science, technology and economy. It has become one of the important symbols of the modernization level of a country, region and city. For different purposes, different people and different regions, intelligent buildings will be people-oriented and provide personalized services for people. It is reported that China's intelligent building design standard defines intelligent building as: taking building as the platform, combining building equipment, office automation and communication network system, integrating structure, system, service, management and the optimal combination between them, so as to provide people with a safe, efficient, comfortable and convenient building environment

since the introduction of intelligent building technology into China in the early 1990s, intelligent building technology has been popularized and applied in China, and its application field has expanded from hotels and business buildings to residential buildings, urban complexes and other buildings. At present, Shanghai, Tianjin, Guangzhou, Shenzhen and other cities have entered a new climax of intelligent building construction. Following the completion of the first intelligent building in China, Beijing development building, Shanghai Jinmao building, Shanghai Shimao International Plaza, Nanjing CITIC Bank building, the new terminal of capital airport and other intelligent buildings have also been completed

for ordinary residents, the charm of intelligent buildings may lie in more intuitive and free control. Last week, homecontrol, an application developed by Siemens to remotely control building automation equipment, was launched in the Android Market. Previously, this application could only be used on Apple's ISO system. The release of Android version means that more users will be able to control intelligent buildings through intelligence. According to the relevant person in charge of Siemens, homecontrol supports six languages, and this application can realize the automatic operation of remote buildings. No matter day or night, users can monitor and adjust the heating, ventilation, air conditioning and other equipment and systems of buildings at any time through this application, so as to make the energy use of buildings more efficient

with this program, users can easily master the current operation status and important indicators of heating, ventilation and air conditioning systems. If the system cannot operate effectively or fails, the application will notify the user. This energy consumption indication function uses symbols in different colors to tell users where adjustments are necessary. If there is a problem, the user can also adjust it directly through homecontrol. For the staff of building property, they no longer need to be stationed in the central control room. As long as one machine is in hand, they can freely master the ventilation, air conditioning, heating, etc. of the building elsewhere. However, homecontrol itself does not take any action, but only reminds customers of various energy-saving possibilities. Enabling remote access can also directly control the comfort of buildings or residences. For example, when people come back from vacation, they can turn on the heating system in advance before they get home; If the shutter is forgotten to close, the owner can close it remotely wherever he is

in addition to the comprehensive wiring and security of buildings, building automation is one of the core systems of intelligent buildings. Ignoring obscure technical terms, the so-called building automation is to detect, analyze and control the electrical equipment in the building to achieve the purpose of unified and efficient management. As the problem of excessive building energy consumption has become increasingly prominent, the requirement for quantitative reduction of energy consumption has become increasingly urgent. Designers should not only take energy conservation as the starting point of building automation system design, but also be able to effectively grasp and measure the effect of energy conservation. In addition, the whole energy-saving process needs to be more intelligent, which can combine data analysis, automatic decision-making and other technologies with manual control of power consumption, temperature control, equipment energy conservation and other measures to provide more perfect and detailed data for energy conservation

in recent years, new changes in design have brought business opportunities to building automation enterprises. Many intelligent product manufacturers began to adjust their business strategies and turn to the field of energy conservation. According to the relevant person in charge of Mitsubishi Electric, Mitsubishi Electric advocates the concept of visual energy conservation. It not only pays attention to improving equipment performance, but also relies on visual and transparent management methods to grasp the trend of energy consumption and put forward targeted opinions on building operation. In the practice of building energy-saving projects, Mitsubishi Electric integrates all kinds of energy consumption into a complete energy consumption analysis system according to the characteristics of school energy consumption, and regularly adjusts energy-saving measures to achieve good energy-saving effects; By analyzing the characteristics of the utilization rate of school buildings, the air conditioning and lighting systems in classrooms, dormitories and other places have achieved a high degree of intelligent automation control, so that the power consumption of the school has decreased

looking forward to the future, the head of Siemens Building technology solutions and services believes that the traditional division between security and building automation is gradually blurring, and perfect and overall crisis management and building automation solutions and value-added services will be the general trend. To meet these needs, the comprehensive building solutions provided by Siemens can realize the integration of multiple technical basic systems: electrical installation, heating, ventilation, temperature control, lighting control, access control, video monitoring, alarm system, fire detection and evacuation system

from fast food restaurants to towering office buildings, buildings have a variety of shapes and sizes. But most buildings have two things in common: a great appetite for energy and great potential for energy efficiency improvement. In fact, according to the statistics of the U.S. and German governments, residential and commercial buildings consume 40% of the world's primary energy and emit 21% of the world's carbon dioxide. Another set of research figures shows that the global energy consumption for building heating and lighting accounts for about 40% of the total energy consumption. However, with the wide adoption of intelligent building management system, the load of power supply and heat supply network will be greatly relieved

therefore, such scenes are becoming more and more common: when the last employee swipes his card to leave the office, all the lights in the office will be turned off automatically; In hot summer, if only twoorthree employees are working in the office, the air conditioner will automatically adjust the room temperature according to the number of indoor personnel; If the room temperature of a room is too low or too high, the system will send the alarm information to the relevant management personnel to remind them that it is still the building made of reinforced concrete, but because of the large invisible information densely distributed in it, the IQ of the building will be upgraded as a whole and become greener. In fact, the development of intelligent building itself and the course it has gone through are also moving in the direction of green building

green buildings are not unfamiliar to us. The most intuitive interpretation is that buildings can achieve the purpose of energy conservation and consumption reduction. Zhongqinghua, the technical director of Siemens Building Technology, said that the International Association has a formal definition of green building. Green building requires that the design, construction and operation of a structure and its surrounding environment should first comply with the more effective use of resources (such as energy, water, raw materials, etc.). Secondly, green buildings should reduce waste, pollution and damage to the environment. Moreover, green buildings can improve the health and productivity of residents. The characteristics of green buildings are that they all have green sustainable site evaluation, so as to achieve building water conservation, energy utilization and atmospheric protection. They make rational use of resources, have excellent indoor environmental quality, and adopt innovative design processes

it can be seen that the definition of green building is not only to install the system in a building and achieve the effect of energy conservation and consumption reduction through hardware, but also to be supplemented by energy consumption monitoring and energy-saving measures to reduce power consumption. Zhong Qinghua introduced that the real cost of the building lies in the design, construction, operation and reconstruction after 60 years. 80% of the cost of a building is generated in operation, of which energy consumption accounts for 40% and operation cost accounts for 60%. Therefore, we have new thoughts on architecture. In buildings, we can invest in insulation materials, heating and cooling, lighting and electrical appliances to reduce emissions. According to Siemens' calculation, the investment return rate of heat supply, refrigeration and lighting emission reduction is the highest

Siemens has been focusing on building energy efficiency since the 1990s. Zhong Qinghua said that through Siemens' contract energy management, customers do not need to bear any cost. Siemens scientifically and reasonably designs and modifies the heating and cooling, lighting and emission reduction of buildings. The raw materials used in the production of composite polyurethane adhesives are petroleum processing products, so as to reduce energy consumption and improve operation efficiency, and pay the costs required by the project through this saved cost. It is understood that Siemens has been widely involved in the field of green and energy-saving buildings, including the first zero carbon building in Hong Kong and the Beijing Chaoyang District government office building

it is reported that Siemens Shanghai, which was put into use in 2011
