Abstract: In recent years, under the background of increasing environmental pollution and resource shortage, energy-saving and environmental protection technology is widely used in civil engineering construction. However, at present, the application advantages of energy-saving and environmental protection technology have not been brought into full play, and the environmental protection performance of civil engineering construction and subsequent residential links still needs to be improved. Taking the application of energysaving and environmental protection technology in civil engineering construction as the research object, this paper analyzes the application significance and shortcomings of energy-saving and environmental protection technology, summarizes the application points of energy-saving and environmental protection technology and specific measures to improve the application level of energy-saving and environmental protection technology, In order to give full play to the important role of energy-saving and environmental protection technology in civil engineering construction, and make civil engineering construction more safe and efficient.
