Abstract: With the rapid development of social economy and the continuous improvement of people's daily living standards, higher requirements are put forward for the construction quality of the construction industry. Therefore, in order to comply with the national development requirements, relevant construction enterprises should integrate green energy-saving technology into the construction process, so as to improve the construction quality and level. Because green energy-saving technology has the advantages of energy conservation and emission reduction, it can reduce energy and resource consumption and reduce the pollution of radiation pollution to the surrounding environment, which is of great signifi cance for the development and construction of China's housing construction industry. Based on this, This paper discusses the development status of new green energy-saving technology in China, analyzes the characteristics of green energy-saving technology and its importance in building construction, and studies the embodiment of green energy-saving technology in design and its application in building engineering construction
