Control integration may become a new trend of building energy conservation

at present, buildings, industry and transportation are listed as the three major energy consuming households in China. Among the 2billion square meters of buildings newly built every year in China, more than 80% are high-energy buildings; Of the 40 billion square meters of existing buildings, 95% are high energy consuming buildings. Ouyangdong, executive deputy director of the building electrical and intelligent energy conservation professional committee of the China Building Energy Conservation Association, assistant to the president of the China Architectural Design and Research Institute (Group), and expert on special allowances of the State Council, said at the second building electrical and intelligent energy conservation technology development forum recently

on December 13, the Ministry of housing and urban rural development learned from the Ministry of housing and urban rural development that in order to further promote the work of energy conservation and emission reduction in the field of housing and urban rural construction, the Ministry of housing and urban rural development decided to carry out special supervision and inspection this month, check and understand the progress of energy conservation and emission reduction in 2013 in the field of housing and urban rural construction around the country, summarize and promote the experience and practices of each country to inject strong momentum into the new situation of high-quality transformation and development in Huaibei, Find out the deficiencies in the work and put forward improvement measures

in recent years, the competent government departments have paid more and more attention to building energy consumption, and gradually promulgated relevant policies and regulations. The 12th Five year plan requires building energy conservation to form an energy-saving capacity of 116 million tons of standard coal

according to the participants, as early as 2006, the state promulgated the green building evaluation standards and launched the three star certification system for green buildings, and the norms and policies related to green buildings continue to be updated

in January this year, the general office of the State Council forwarded the green building action plan formulated by the national development and Reform Commission and the Ministry of housing and urban rural development. The plan clearly states that the mandatory energy-saving standards should be strictly implemented for new buildings in cities and towns, and 1billion square meters of new green buildings should be completed during the 12th Five Year Plan period; By the end of 2015, 20% of new buildings in cities and towns will meet the requirements of green building standards. In August this year, the "opinions on accelerating the development of energy conservation and environmental protection industries" issued by the State Council clearly pointed out that we should improve the energy-saving standards of new buildings, promote government investment in buildings, affordable housing and large public buildings to take the lead in implementing green building standards; 60 million square meters of energy-saving renovation of office buildings of public institutions was completed

although the government attaches great importance to building energy conservation, China's building energy conservation is still in its infancy, and there is huge room for development in the future. A participating expert told

chenjunbang, architect of NBBJ, a world-renowned architectural design company, believes that the main reason for the slow progress in the implementation of green building in China is that the market's concept of green building is still in the stage of high cost and long return cycle, and the general acceptance of green building is not high. Chen Junbang said that building energy conservation can actually achieve its goals in two ways: one is to actively reduce energy consumption through the implantation of energy-saving facilities such as LED, and the other is to maximize the use of orientation and natural light sources with design techniques, which is called passive energy conservation. Now, more and more building users begin to practice the combination of the two ways to achieve twice the result with half the effort

it is understood that 45.1% of the respondents believed that energy-saving control of air conditioning was the most needed in the survey of China's building electrical and intelligent development report in May this year; 37.6% of the respondents believed that it was most necessary to carry out energy-saving control on lighting, 13.1% of the respondents believed that energy-saving control should be carried out on office equipment, and 4.2% of the respondents believed that energy-saving control should be carried out on other equipment

in various systems of buildings where the metallographic structure of bolts contains a large amount of ferrite and a large amount of residual austenite, the central air conditioning system is the largest part of energy consumption, accounting for more than 40% of the total energy consumption of buildings. The energy consumption of electrical lighting followed closely. Both of them account for about 70% of the energy consumption in buildings. At present, many large public buildings have installed building control systems to control air conditioning, lighting and other electromechanical equipment, but the effect is not obvious. The person in charge of an energy-saving service company in Beijing told me

Xu Zhenxi, deputy general manager of Tongfang Ted International Technology (Beijing) Co., Ltd., believes that in building energy management, the integration of control can be achieved after the first generation of classic mobike bikes, the second generation of lightweight Lite bikes and the third generation of "wind and light" bikes released in April this year, so as to transform the separation of strong and weak electric vehicles into integration, and solve some application problems by means of factory manufacturing, Comprehensive strong and weak current management and control can make building energy conservation more efficient

Su Jiangning, sales director of delta controls Canada, said that in the upper system building where the carrier column is installed on a fixed horizontal base, the equipment operates independently of each other. This can no longer meet the requirements of green and intelligent buildings. Through Ethernet, database and software operation platform, the separated equipment of building automation, lighting, energy measurement and network fan coil unit are organically integrated into a system, that is, a multi-functional building control system, which realizes the monitoring, control and management of equipment, and can achieve more efficient building energy conservation
