Application and Impact Assessment of Renewable Energy in Construction Projects

As a new type of environmentally friendly energy, renewable energy is widely used in various fields of society, and its purpose is to reduce the pollution of social production to the environment. For the research on the application effect of renewable energy, there are few cases and insufficient research depth. In order to solve the above problems, this paper proposes an improved regression analysis method, which refers to the construction engineering yearbook of 2020~2022 and the actual construction project as a case for analysis, and compares with SPSS, Mintab and other software to verify the effect of renewable energy application before and after. Among them, the complex data in renewable energy and construction projects are processed by binary classification, and the data with large field spans and low similarity are scaled to improve the unity of research content. The results of the study are realistic: renewable energy has an impact on energy consumption, cost and CO2 emissions in construction projects, and the reduction range is between 10~20%, and there is a positive proportional relationship. At the same time, the application of renewable energy is directly affected by energy policy and environmental policy, and the impact coefficient is between 0.3~0.5. This shows that the application potential of renewable energy in construction projects is huge, and the development sustainability of construction projects is improved.
