With the improvement of urban development level,the overall quality level of new and old buildings in the city has a certain difference. During the construction phase of the new construction project,more new technology and construction materials were applied,and the overall quality and functionality of the building were upgraded to a new level by using green and energy-saving building materials. The old buildings in the city have practical problems of energy loss. In order to ensure a better development space for China's urban construction,and to ensure that construction companies can compete in a fiercely competitive environment.It is crucial to fully optimize the energy efficiency of buildings through energy-saving renovation projects. This paper analyzes the shortcomings of the energy-saving and loss-loss work of building construction in China at present,and brings a relative strategy on how to strengthen the construction level of energy-saving renovation. I hope to bring certain reference value to the relevant workers.
