1 preface
The development of construction industry is deeply influenced by economic and social and cultural development. Under the background of vigorously developing environmental protection in the world, the construction industry will also be affected and develop in the direction of green and environmentally friendly buildings. Buildings occupy a lot of land resources in the construction process, and secondly, a lot of materials such as glass are used in the design process, which seriously affects the environment. Therefore, it is of great significance for the development of global environmental protection to vigorously promote the process of green environmental protection in the construction field. The following will explain the concept of green environmental protection technology and its application value in engineering, summarize the application status of environmental protection technology in the construction field, and put forward the development prospect of environmental protection technology in the construction field.
2 Overview of energy-saving and green environmental protection technologies
Generally speaking, energy-saving green environmental protection technology is a variety of technologies developed based on the principles of energy saving and ecological environment protection. Under the background of global environmental protection, energy-saving and green environmental protection technologies have been vigorously developed and widely used in various fields, and the construction field is one of them. As far as the construction field is concerned, green environmental protection technology refers to the continuous improvement of project management level and the introduction of advanced technology and construction technology in the process of project construction, with the aim of energy conservation and environmental protection and on the basis of ensuring the project quality. With the full implementation of environmental protection policy in recent years, green building requirements have been put forward, specifically to ensure that the whole engineering building can meet the requirements of energy saving, water saving and electricity saving [1].
3 the inevitable trend of energy-saving and green environmental protection technology in engineering application
Environmental protection in the field of architecture is mainly manifested in the rational application of building materials and the development and utilization of new building energy, thus improving the availability of building materials and reducing the waste of building materials. During the construction of a building project, it is a common phenomenon that garbage is randomly piled up around the project, which seriously affects the surrounding environment. In view of this, the introduction of green environmental protection technology in the construction process can effectively improve the construction efficiency, shorten the construction period, reduce the amount of engineering waste and reduce the impact period of construction on the surrounding environment. In addition, glass or other materials that affect the natural environment will be widely used in traditional engineering construction, and the introduction of green materials or construction technology can reduce the application of such building materials that are not conducive to environmental protection. No matter what direction is given, green building will be the inevitable trend of development in the field of architecture [2].

4. 1 application of energy-saving technology in external wall insulation engineering
Energy-saving technology of external wall insulation is to set insulation layer on the external wall of the building, so as to achieve energy-saving effect. External wall thermal insulation technology has certain continuity, which can avoid the common phenomenon of broken bridge in traditional walls. At the same time, the thermal conductivity of polystyrene board used in external wall insulation technology is relatively small, which can reduce the heat loss in the engineering room. In addition, the application of external wall thermal insulation technology can reduce the weight and thickness of the wall, thus increasing the applicable area of the building. The participation of external wall thermal insulation technology in the building will not only affect the quality of the whole building, but also improve the comfort of the building because of its increased heat storage function [3].
4.2 Application of Photoelectricity, Photothermal Energy Saving Technology in Building Engineering
The photoelectric and photothermal technologies used in buildings are mainly photoelectric energy-saving technologies and photothermal energy-saving technologies. The applied energy mainly comes from the conversion of solar energy, which can be converted into usable energy to provide the heat and electric energy needed by buildings. The advantages of photoelectric and photothermal energy-saving technologies are that solar energy is a renewable resource, sustainable and harmless, suitable for long-term application, and can realize the energy-saving effect of buildings on the basis of providing convenient energy. In addition, solar energy does not need to be transported or complicated conversion process, and the conversion device can be directly installed in the building, thus realizing the application of solar energy and reducing the process cost. However, it is worth noting that solar energy can not keep a balanced amount for a long time with the changes of seasonal and regional factors, and it belongs to phased application energy, which has certain future development potential.
4.3 Application of energy-saving technology of ground source heat pump in building engineering
Ground source heat pump is also a kind of refrigeration and heating technology, which is often called geothermal. The application of ground source heat pump technology can provide heating for buildings in winter and cooling function in summer, and realize intelligent adjustment of buildings, which has certain practical significance and is also a common application technology in buildings at present. The application advantages of ground source heat pump technology in buildings lie in its small floor space and compact layout. At the same time, the application of energy-saving technology of ground source heat pump can prevent the problem of building ground subsidence, and this technology is relatively mature at present, and the construction is relatively simple, which can provide long-term stable heat energy and refrigeration supply.
Application and development prospect of energy-saving and green environmental protection technology in architecture
Environmental protection and energy saving are the primary problems facing the current social development, such as reducing the waste of resources, improving the utilization rate of various resources, and strengthening the development of environmental protection energy and materials. Under the background of environmental protection, the construction industry, as the main leading industry, must take the lead in setting an example and make contributions to the development of environmental protection. As far as the application of green environmental protection technology is concerned, it has great development potential in building engineering. The concept of building greening is bound to involve the transformation of building mode and material application, and the application of environmental protection energy and materials is bound to be involved in the process of transformation. Based on this, environmental protection technology has great application value and development prospect in the field of architecture.
6 conclusion
To sum up, under the background of environmental protection, green building will become the inevitable trend of future development, and the realization of environmental protection building or green building will involve the application of large-scale environmental protection new energy.
