Abstract: Civil engineering is an important part of the construction industry, and is closely related to people's lives. With the continuous development of economy, People�s quality of life has been signifi cantly improved, at the same time, the requirements for the environment are also increasing. Therefore, the application of energysaving design tocivil buildings can improve energy effi ciency and contribute to the sustainable development of civil engineering. This paper discusses the application principle of energy-saving design in civil construction, and puts forward the strategy of energy-saving design in architectural design.
