Establishment of a green degree evaluation model for wall materials based on lifecycle

Abstract With the increasing demand for green and environmentally friendly building materials, the development of the building materials industry is gradually moving toward an ecological and sustainable direction. At present, there are various indicators for evaluating the greenness of wall materials, and the evaluation methods are mainly in view of personal experience. Therefore, this study designed a green degree evaluation model for wall materials. The model is first in view of the lifecycle of the wall material, considering factors that affect the greenness of the wall material. Then, an improved mathematical hierarchy process is used for modeling, and finally, indicator weights are calculated, and the model is simulated for application. The results indicate that the model can reasonably and accurately rate the greenness of wall materials with different characteristics and has high scientific and practical significance. The survey results show that the satisfaction level of the model is high, indicating that it has broad application prospects and development potential in practical applications and can provide strong support for promoting the sustainability and green development of the building materials industry.
