Rely on science and technology innovation to improve the level of green construction?

How to rely on scientific and technological innovation to improve the level of green construction, the following Zhongda Consulting for you to bring relevant content for reference.

The economic form of human society has experienced three kinds of agricultural economy, industrial economy and knowledge economy. Along with the evolution of energy consumption through the natural environment, a small amount of energy consumption carbon emissions to a large number of burning coal fuel carbon emissions development process. The massive consumption of natural resources has led to the increasingly poor natural environment, manifested in serious ecological pollution, global temperature rise. With the deepening of people's awareness of the importance of the environment, the low carbon economy in the era of knowledge economy has been the global people's **** knowledge, people strongly hope that through the global emission reduction and carbon limitation to achieve the purpose of improving the environment. Therefore, low carbon economy is the inevitable trend of civilization progress. China's national conditions make energy-saving low-carbon cycle has become a necessary path of economic development. At present, the contradiction between China's economic and social development and resources and environment is becoming more and more prominent, seriously restricting the sustainable development of society. According to China's specific national conditions of many people and few resources, the central government proposes to make resource conservation a basic national policy, develop a circular economy, protect the ecological environment, accelerate the construction of a resource-saving and environmentally friendly society, and promote the coordination of economic development with population, resources and the environment, which is of very strong practical relevance. In all social production activities, the natural resources consumed by construction activities account for 40%; in all the garbage, the garbage generated by construction activities also accounts for 40%. Therefore, the construction industry in the construction of resource-saving, environmentally friendly society bears an incumbent social responsibility. Building construction technicians should enhance the sense of social responsibility, constantly improve the level of green construction technology, and strive to provide scientific and technological support for the construction of energy-saving construction enterprises.1 Green building, green construction awareness 1.1 Green building connotation of the current construction of the following characteristics: ① building energy consumption for the whole life of the human energy consumption of the most; ② building is the closest human life environment; ③ building is the environment of environmental pollution is also the environment beautification Green building should conform to the following characteristics. Green building should meet the following characteristics: ① green building should be in line with the functional conditions of a number of programs in the whole life of the least energy-consuming, the most environmentally friendly one; ② green building is a low-carbon and recycling economy, the inevitable requirements of sustainable development; ③ practical, economic, and may be the conditions of the aesthetics of the predecessor of green building should be said to be.1.2 green construction connotation is well known, the building is the closest to the environment of human life. Research shows that the whole life of the building consumes the most energy for human beings. Therefore, building construction is the construction process of realizing the design function of the building entity, green construction is an integral part of green building, and green building is an important prerequisite for green construction. Green construction, as an important stage in the whole life cycle of a building, is a key link in realizing resource conservation and energy saving and emission reduction in the construction field. Green construction refers to construction activities that maximize resource conservation and reduce negative impact on the environment through scientific management and technological advancement to achieve energy saving, land saving, water saving, material saving and environmental protection (four savings and one environmental protection) under the premise of guaranteeing the basic requirements of quality and safety in engineering construction. Green, energy-saving, environmental protection is the purpose of green construction. According to the 3R principle of reduce, reuse and recycle, it coordinates the saving, recycling and reuse of resources and energy, reduces the consumption of resources and energy, reduces the emission of pollutants, and reduces the impact of construction on the environment. Traditional construction is characterized by high input, high consumption, high emissions and low efficiency. In comparison, the characteristics of green construction include resource conservation, energy saving, environmental friendliness, and economic efficiency. At the same time, good, fast, save and safe are the traditional construction goals; land saving, water saving, energy saving, material saving and environmental protection are the green construction goals. Therefore, green building, green construction and traditional building, traditional construction is not antagonistic, is the inheritance of development, is in the new period of harmonious enhancement.2 The road of green construction implementation of green construction, should be based on the principle of local conditions, implementation of the national, industry and local relevant technical and economic policies. Green construction should be the embodiment of the concept of sustainable development in the comprehensive application of engineering construction, and not only refers to the implementation of closed construction, no dust, no noise nuisance, planting flowers and grasses around the site, the implementation of regular sprinkling, etc., but involves all aspects of sustainable development, such as ecological and environmental protection, resource and energy utilization, social and economic development. Specifically include the following aspects.2.1 Continuing education, enhance the concept, consciously green construction action is governed by the idea, the idea is driven by the concept. Therefore, green construction should start from the continuous education of the whole staff, only to enhance the concept of green construction of the whole staff, only the leadership of the enterprise attaches importance to the staff consciously, green construction can be durable and constantly improve. The connotation of green construction is very rich, the realization of green construction must be a big place to look, small place to start, must be innovative construction concepts, construction techniques, construction equipment and construction technology. Green construction must be an enterprise-wide action. It is necessary to implement scientific management, improve the level of enterprise management, so that the enterprise from passive adaptation to active response, so that the enterprise to implement green construction institutionalized, standardized. This will give full play to the role of green construction in promoting sustainable development, increase the economic effect of green construction, and improve the enthusiasm of contractors for green construction. Engineers and technicians must firmly establish the concept of green construction. Green construction is a resource-saving, environmentally friendly construction method. The concept of green construction has penetrated into the advanced construction enterprises and employees in western developed countries. For example, the environmental annual report of Japan's Daelim group announces the company's CO2 emission control, construction waste reduction, toxic chemicals control and green procurement, etc., in order to gain trust from the community and improve the corporate brand image, which is worthy of our reference.2.2 Standardize, Institutionalize, and Improve the Level of Green Construction Management 1) Green construction technology depends on the management of the implementation and protection of green construction management should be based on the concept and system of the traditional construction management, and should be implemented and guaranteed. Green construction management should be based on the concept of construction management and system on the comprehensive improvement. 2) Management should have an organizational system to support the typical green construction organizational system as shown in Figure 1. 3) Standardization, institutionalization is the guarantee of long-term management green construction management should be based on lessons learned, combined with the actual level of construction technology and the actual development of a number of rules and regulations, but also through the regular assessment of a series of rules and regulations to mark the progress with the times. 4) The green construction management should be based on the actual level of construction technology and the actual development of a series of rules and regulations. Warning, the establishment of standardized facilities. 4) Green construction of the management system to enhance the green construction of the construction organization design to enhance the green construction, at least in the good, fast, save, safe on the basis of increasing the content of water conservation, land conservation, environmental protection, regeneration, and to increase the selection of the appropriate technology, the appropriate measures, the appropriate equipment. The general catalog of construction organization design should increase the chapters, and each sub-item should have green measures.2.3 Comprehensive integration and optimization, and constantly improve the green construction technology inheritance optimization and integration of traditional and practical construction technology, absorption and application of re-innovation of foreign green construction technology, and independent innovation of advanced green construction technology.2.3.1 Effective combination of traditional crafts and new technologiesIt should be pointed out that the traditional technologies all have the further improvement of the green level of the subject. For example:The use of 0-negative tolerance (computer joining); the reduction and application of flooring materials; construction measurement of fine positive leveling layer reduction and cancellation; the use of well-point water and so on. Practical summary to enhance the level of traditional practical green construction technology, vigorously promote the Ministry of Housing and Urban-Rural Development issued by the construction industry ten new technologies (2010): foundation and underground space engineering technology; high-performance concrete technology; high-efficiency reinforcing steel and pre-stressing technology; new type of templates and scaffolding application technology; steel structure technology; installation engineering application technology; energy-saving and environmentally friendly construction application technology; construction waterproofing new technology Construction process monitoring and control technology; construction enterprise management information technology. 10 new technologies are good, fast, save, safe and other aspects of the effect, and therefore have the significance of green construction, should be based on this to improve the level of green construction. For example: pile side grouting; early dismantling technology; high-performance concrete; top, push, rise assembly steel structure.2.3.2 Traditional technology innovation in the absorption and application of foreign advanced green construction technology on the basis of innovation and application according to China's national conditions, which is an effective shortcut. For example, quick-dismantling platform template, prefabricated assembly heat preservation residence and so on. The following highlights the innovative application of the following technologies in China.1) Underground engineering cover digging method cover digging method is excavated from the ground down to a certain depth, the top will be closed, and the rest of the lower works in the closed roof under construction. The main structure can be worked along or against. When subway stations are constructed in busy urban areas, they often occupy roads and affect traffic. When the subway station is located on the main road, and the traffic can not be interrupted, and need to ensure a certain traffic flow requirements, cover excavation method can be used. Therefore, the cover digging method is the local underground engineering Ming do need to cross the highway, buildings and other obstacles and take the new engineering construction methods, Shanghai has more than underground deep foundation pit project applications, such as the Shanghai Bund channel renovation project, etc. 2) residential prefabricated assembly process residential prefabricated assembly process using industrialized production methods. Is part or all of the components of the residence in the factory prefabrication is completed, and then transported to the construction site, the components will be assembled through a reliable connection and built homes, in Europe and the United States and Japan is known as industrialized housing or industrialized housing. Introduced into China in recent years, and has been the initial development. 3) electromechanical pipeline prefabrication assembly process of modern building mechanical and electrical installation is moving towards the direction of factory and assembly, its basic feature is that all the work is clearly divided into two parts of prefabrication and assembly. Neither affected by the weather nor restricted by the conditions of civil construction and equipment installation, it can shorten the construction cycle, accelerate the construction progress, reduce the erection of overhead work and overhead work aids, and ensure the quality and safety of construction.
