Energy conservation and environmental protection in building construction?

With the continuous development of China's economy and the continuous progress of science and technology, people's requirements for the quality of life are getting higher and higher, and their understanding of the concept of environmental protection and energy conservation is getting higher and higher. Green building has become a new concept in the construction industry, and energy-saving and environmental protection technology has also become a new means to enhance the competitiveness of construction enterprises. In building construction, strengthening the effective application of energy-saving and environmental protection technologies can effectively reduce the energy consumption of houses in the process of building construction, and also meet the requirements of low-carbon and environmental protection economic development. This paper analyzes the current application status of energy-saving technology, and puts forward relevant strategies on how to make better use of energy-saving and environmental protection technology.

With the development of society, China's construction industry has made great progress, but at the same time it is facing new problems-the shortage of resources and energy, which has brought severe challenges to the smooth development of construction projects. In view of this problem, the construction industry should analyze according to the actual situation and use science and technology to make the limited resources play the maximum value.

1 application status of building energy-saving construction technology

1. 1 Construction engineering resources are seriously wasted. Although many building materials can be recycled, this way of recycling materials has not been fully utilized in some construction enterprises. In addition, in the construction site, many materials are piled up at will, and there are no perfect storage measures, which also leads to materials being discarded for various reasons and serious waste. 1.2 The policy of energy-saving buildings has not been thoroughly observed and implemented, and the publicity of environmental protection policies by relevant departments is not in place, resulting in the lack of sufficient cognition and attention of leaders and responsible persons in some areas to the technical concept of energy-saving buildings; Some people are only in the form of energy-saving and environmental protection technology, and have not implemented it in practical work.

2 the application value of energy-saving and environmental protection technology in residential construction

The application of energy-saving and environmental protection technology in building construction is of great significance, which is conducive to saving materials and energy at first. Compared with ordinary materials, the price of new environmental protection materials seems to be higher, but the purpose of using energy-saving materials is to better save energy, minimize energy consumption during construction and promote the sustainable development of construction enterprises. Secondly, the application of energy-saving technology can effectively reduce construction costs, make construction enterprises achieve greater economic benefits and promote the development of construction enterprises. Housing will consume a lot of energy and resources in the construction process. Adopting reasonable energy-saving and environmental protection technology can effectively integrate manpower, material resources and financial resources, save resources and ensure construction quality.

3 Application of energy-saving and environmental protection technology in building construction

3. 1 application of building materials. Steel, cement, wood, etc. Are common materials in building construction. In the selection of raw materials, modern energy-saving and environmental protection materials should be reasonably selected, and the material quality and data parameters should be strictly reviewed according to the architectural design requirements, which should meet the relevant standards [1]. Consider and analyze the economy, health and efficiency of materials from many aspects; In the construction process, pay attention to the construction technology, and carry out the construction on the basis of energy saving and environmental protection. For example, in building roofs and walls, materials with high thermal insulation and good waterproof performance can be used; In the structure of doors and windows, modern new transparent heat insulation glass is applied.

3.2 Save energy. The application of new energy in building construction will have a good effect. In actual construction, it is necessary to make a reasonable and scientific analysis of the building environment, and then select energy-saving materials according to the scientific design of the building, so as to maximize the advantageous value of energy saving, so as to realize energy saving in residential construction [2]. For example, in the process of building construction, when the rational use of solar energy plays a greater role, effective measures are taken to maintain the protective structure around the building to increase the safety and environmental protection of the building. The traditional building envelope consumes a lot of heat, but the modern building envelope has been effectively improved on the basis of new energy, and the energy-saving effect has been improved.

3.3 Building wall energy-saving and environmental protection technology. The wall is an important part of the house. Traditional walls are mostly made of solid clay bricks. Although the cost is low, its thermal insulation performance is poor, and the thickness to be stacked should meet the relevant standards, which causes a waste of resources to some extent. The composite wall technology can be used in modern housing construction, and the purpose of energy saving and environmental protection can be achieved by using modern science and technology.

3.4 Energy-saving and environmental protection technologies in roof construction. In building construction, we should take energy conservation and environmental protection as the concept, and formulate appropriate construction technology according to the actual situation of the construction site, so as to achieve a high degree of unity. For example, the environment and climate in the building area will have an impact on the construction. When selecting materials, analysis and research should be carried out according to the actual construction site to ensure the adaptability of construction technology. The building area is characterized by warm winter and cool summer. During the construction process, the roof ventilation should be controlled reasonably to ensure the air is dry.

3.5 Energy-saving and environmental protection technologies for doors and windows. People have higher and higher requirements for the lighting of the living environment. In order to meet the requirements of residents, it is necessary to increase the reserved area of doors and windows in the construction process, so that the insulation effect of doors and windows and lighting can be better played, which also increases the difficulty of construction to some extent. With the continuous progress of building technology, the thermal insulation technology of many doors and windows products has been improved, and the performance of some metal doors and windows has been improved, which makes the heating and thermal insulation aspects well solved [3]. The environmental protection and energy saving of doors and windows are mainly manifested in solar heat gain, thermal insulation, lighting, air permeability and so on. At present, the existing materials in building construction are mainly hollow glass with low radiation and thermal cutting. Some ways to achieve the above objectives are to increase the number of glass layers in doors and windows or to paste transparent ester molds.

4 conclusion

With the continuous development of science and technology, new energy and new materials have been widely used in various fields of the construction industry and played a huge role. In actual construction, construction enterprises should fully understand the significance and value of energy-saving and environmental protection technologies, select reasonable materials, enhance employees' awareness of environmental protection, improve the technical level of construction-related personnel, scientifically and reasonably adopt energy-saving and environmental protection technologies in roofs, walls, doors and windows of housing construction, give full play to their energy-saving and environmental protection values, and promote the stable development of housing construction industry.
