1, the importance of energy-saving and environmental protection technology in building construction
Energy-saving in building construction mainly refers to the scientific development and utilization of new energy, improving energy utilization and reducing energy consumption while effectively and rationally utilizing existing energy in the construction process. In today's era of dust and garbage everywhere, people urgently need a comfortable and clean living environment.
If new environmental protection materials can be used in building construction, it can not only reduce resource consumption and waste discharge, but also improve people's living environment, which is very beneficial to people's living environment and health level. At the same time, it is helpful to improve the ecological environment and protect various endangered species to a certain extent. The application of energy-saving and environmental protection technology in building construction has shortened the construction period and accelerated the progress, thus reducing the installation cost of engineering buildings. The application of energy-saving and environmental protection technology in building construction will improve building construction technology, work efficiency and construction quality, and create huge economic and social benefits, which is the need to promote building construction progress and conform to the needs of the times.
2. Problems existing in energy conservation and environmental protection in building construction.
First of all, some backward construction units are still in use because of aging equipment. The management of the enterprise only considers the construction cost increased by upgrading the construction infrastructure, but does not consider the waste of water, electricity and materials caused by the use of aging equipment in construction, and the waste of resources caused by inefficient equipment and its impact on the construction process.
Second, the enterprise energy conservation and environmental protection management mechanism is not perfect. If a scientific and reasonable management mechanism for energy conservation and environmental protection is not established or there are too many loopholes in the existing management mechanism, the responsibility cannot be effectively implemented, and the assessment and supervision are not done well, it will be difficult to implement real energy conservation and environmental protection.
Third, and most importantly, enterprises' awareness of energy conservation and environmental protection is not strong, which makes energy conservation and environmental protection technologies unable to play an effective role in enterprise development. It is a common phenomenon that management neglects to implement relevant national laws and regulations and fails to make good use of existing energy conservation and environmental protection technologies. Moreover, the government's supervision and punishment measures are not clear enough, which seriously hinders the implementation and promotion of energy-saving and environmental protection technologies.
3. The application of energy-saving green environmental protection technology in building construction
3. 1 New energy-saving and environmental protection materials in building construction
Building energy conservation plays an indispensable role in implementing the strategy of sustainable development. The application of building materials is an important part of building construction. Modern green building materials have excellent quality, good performance and high environmental coordination. It has the characteristics of relative safety in use, less pollution after use and reusability to some extent. There are many kinds of green building materials used in modern architecture. Let me briefly introduce some of them.
First, modern green concrete materials. Concrete is the main material of modern buildings, and the use of green concrete is an important embodiment of developing green buildings. Concrete has excellent applicability, workability, durability, stability, economic rationality and various mechanical properties. There are many classifications, such as high-performance concrete materials, green concrete, aerated concrete, synthetic fiber concrete, hollow precast concrete and so on. In addition to their excellent characteristics, they also have their own unique good performance, which is conducive to saving resources and protecting the environment.
The second is wood. There are many special kinds of wood in modern building materials, such as colored wood, which can be divided into congenital coloring and acquired coloring, porcelain wood, plasticized wood, hydrophobic wood and so on. , has been well applied in different occasions.
The third type is thermal insulation material, which can be divided into two types according to different states: plate-like and slurry-like, and can be divided into internal and external thermal insulation materials according to different parts of the enclosure structure.
Four, waterproof materials, modern green building materials should not only have waterproof function, but also have decontamination, heat preservation and other functions that have little impact on the environment. Polymer cement waterproof coating, permeable crystalline waterproof material, plastic leak-proof agent and polyethylene double-sided composite waterproofing membrane are all good waterproof materials. Wood, stone, clay brick, concrete and steel are all traditional building materials, and now the main structural materials are concrete and steel. Wood is renewable but slow, and stone is resource-consuming but durable, all of which have the characteristics of green building materials, but also have their limitations. An effective backup resource is bamboo panels. Clay brick has low energy consumption, but it needs to be used at the expense of destroying fertile land. Production and use have been banned now. Its green alternative building material is industrial waste residue, which has rich sources and superior mechanical properties to clay bricks, and has broad application prospects. Steel is irreplaceable, so it is urgent to develop "green steel" with low energy consumption and less emissions. The use of green steel is a breakthrough in the use of traditional building materials, and its advantages are self-evident.
3.2 Technical measures for energy saving and environmental protection
The first is to improve the management mechanism. At present, construction enterprises are weak in supervision and management of environmental protection and energy conservation. In view of this situation, construction enterprises in the new period must constantly improve the management mechanism of building energy-saving and environmental protection technologies to ensure that energy-saving and environmental protection technologies are effectively applied in construction enterprises. On the basis of establishing and perfecting the management mechanism, the corresponding restraint and punishment mechanism should be established to ensure the effective operation of the established mechanism. Secondly, in view of the phenomenon that some construction units are still using aging equipment and wasting resources, it is necessary to have a long-term vision for the development of enterprises to eliminate these inefficient energy-consuming equipment and introduce new energy-saving and environmental protection equipment.
Third, the waste generated by construction should be reused. Construction waste has a huge renewable utilization space, so we should increase the technical development and support for its comprehensive utilization, learn from the advanced experience of predecessors, take good energy-saving and environmental protection measures for every step of the construction plan, strengthen supervision, reduce the amount of waste generated and improve the utilization rate of building materials. Fourthly, the following principles should be adhered to when adopting energy-saving and environmental protection technologies in building construction: First, energy-saving technologies should not be popularized at the expense of building functions; Second, it is necessary to combine the reality, adhere to the people-oriented principle, ensure the effectiveness of building energy-saving construction, and ensure and improve the comfort and comprehensiveness of energy-saving buildings.
Fifth, the application of energy-saving and green environmental protection technology in building construction requires construction workers to have certain professional skills, so it is necessary to strengthen the professional technical training of construction workers and improve their professional technical level.
Sixth, the construction of modern construction enterprises needs to use modern science and technology, so it is necessary to constantly innovate and improve building energy-saving and environmental protection technologies to promote their application level, accelerate the popularization and application of high-performance materials, and improve the utilization rate of resources; Choose energy-saving technology to reduce energy consumption; In addition, we should strengthen the application of clean energy technology, put an end to the use of polluting materials and control the discharge of harmful substances.
Seventh, the application of all energy-saving and environmental protection measures and technologies requires enterprise managers and construction workers to have a strong awareness of energy-saving and environmental protection. Only when construction workers deeply understand the significance of energy conservation and environmental protection, and actively engage in learning and using instead of passively accepting, can the effective use of energy conservation and environmental protection technologies be guaranteed. Therefore, people at all levels should deepen their awareness of energy conservation and environmental protection.
4. Conclusion
Energy conservation and environmental protection in building construction is an important means to implement the sustainable development strategy, which not only saves resources and protects the environment, but also benefits the development of enterprises and society, in line with the current global development trend. With the remarkable improvement of people's living standards, people have higher requirements for good environmental conditions. In the past, we only pursued social and economic development without paying attention to improving environmental benefits, which caused extremely serious environmental pollution, wasted limited natural resources and destroyed the good living environment in the past, which not only adversely affected economic development, restricted the sustainable development of society, but also affected our own living standards. The polluted environment also has a certain impact on our own health. Architecture plays an important role in environmental protection and energy consumption. If energy-saving and environmental protection measures can be implemented in building construction, it will help solve the current environmental problems, improve the ecological environment and create great benefits. Relevant enterprises should have a long-term vision, effectively use energy-saving and green environmental protection technologies, and lay a solid foundation for promoting the development and stability of enterprises.
