1 Analysis of Building Energy Consumption in China
Judging from the consumption of various resources in China at present, the energy consumption of coal and petroleum resources is in the forefront of the world, and China is also a very large consumer country. China's economic development is inseparable from energy consumption, but if we don't pay attention to energy conservation and realize efficient use of energy through green emission reduction, then China will encounter energy crisis in the future. 2 1 century, China's economy developed rapidly and people's living standards improved continuously. The construction of building projects is increasing in speed and quantity. At the same time, the energy consumption has been rising in a straight line. However, there are few enterprises applying green energy-saving technology in buildings, and they can't basically complete the construction according to the standards of green emission reduction, resulting in large energy consumption, which is an important reason why China urgently needs energy conservation at present.
2. The current problems of energy saving in civil engineering buildings
2. 1 Lack of correct understanding of energy-saving housing.
Developers and construction units of many construction projects in China pay insufficient attention to energy conservation and emission reduction. Although energy-saving materials and technologies have been widely promoted in recent years, many people have not applied them to practical projects, and many projects have not adjusted their technologies in time. In order to obtain more economic benefits, some developers have applied some European architectural styles that are not in line with the actual situation, which not only leads to the formation of energy-saving targets, but also has a great impact on the functions of buildings. In addition, there are many available energy sources in the built environment, but they are not fully used, thus causing great waste of energy.
2.2 The technical level of energy conservation and emission reduction needs to be improved.
In China's civil engineering construction industry, the goal of energy conservation and emission reduction is very clear, and the slogan is memorized, but it is not reflected in actual actions. Even in the application, there are many problems. For example, in the aspect of civil engineering building energy saving, although it is involved, it has not achieved its actual effect, which has a great relationship with the advanced choice of energy-saving technology and has not achieved good use effect. For building energy conservation and emission reduction, this is a technical content that needs to be adhered to for a long time and needs to be implemented in every construction link.
3 effective measures for building energy conservation in civil engineering
3. 1 Improve resource utilization
Energy saving and emission reduction in construction projects need the cooperation of building materials and technologies. Therefore, relevant staff should actively apply new technologies and materials in the process of technological innovation to ensure the high quality and performance optimization of construction projects, and scientifically apply various local resources to improve the utilization efficiency of these resources and reduce the waste caused by on-site construction. For example, the active application of renewable energy and clean energy is the main development goal. For some civil construction projects, solar energy technology and wind technology can be better applied. Through the application of solar power generation system, solar cells can be saved, and solar energy can be converted into electric energy, which can be used at night if electricity is needed. The application of this technology can not only reduce the waste of coal resources, but also minimize the waste of related resources.
3.2 establish and improve the building energy-saving management mechanism
Building energy conservation needs to be improved and built, and energy conservation management system is the most basic guarantee. However, in the actual situation, there is a relative lack of energy-saving technology, and many rules and regulations and supervision systems are not perfect, which leads to no basis for implementation. In order to promote the energy-saving management of China's construction industry, relevant departments should earnestly strengthen the implementation of all links, establish technical rules and regulations for construction units, improve laws and regulations, and ensure the construction industry to achieve energy-saving goals from the legal point of view.
3.3 "people-oriented" as the guiding concept
The concept of energy conservation is to compare energy conservation with simple houses and low-standard buildings in the traditional way of thinking, but this idea is definitely wrong. We should apply the concept of energy saving to the whole construction process while improving the quality of construction projects. Social development and energy saving are necessary development contents. Only when everyone in the society can understand the concept of energy saving in place can we strengthen people's sense of responsibility and optimize the efficiency of resource use. Building energy efficiency is a policy that benefits the country and the people. People should actively adopt energy-saving building methods, reduce resource consumption, improve building efficiency and optimize its performance.
3.4 Strengthen the training of professional and technical personnel and construction personnel.
In the application of energy-saving technology, in addition to adopting new energy-saving building materials, it is also necessary to improve the technical ability and comprehensive quality of employees. Many energy-saving technologies are relatively complex and have high technical requirements. Therefore, relevant enterprises should strengthen the training and education of on-site staff, so that every staff member can have energy-saving awareness and technical ability, master energy-saving technologies in an all-round way, and apply them to every link of construction projects, which is more conducive to the research and application of building energy-saving technologies. In short, from the current energy utilization efficiency in China, the overall development of the construction industry has a certain impact on the surrounding environment, and there is a waste of resources. Therefore, it is very important to strengthen the coordination between construction industry and environment. Therefore, in the process of civil engineering construction, we should strengthen people's satisfaction with the quality of life, actively explore the energy washing problem in the construction industry, and put forward targeted solutions to make outstanding contributions to the energy conservation and environmental protection work of construction projects.
