[Retracted] Evaluation Algorithm of Ecological Energy-Saving Effect of Green Buildings Based on Gray Correlation Degree

Table 1

Classification of environmental protection evaluation standards.

Division of primary and secondary factors of evaluation	Environmental protection evaluation index	Evaluation criteria and equivalent division results
Main evaluation grade classification criteria	Main sources	Subsidiary indicators affecting the evaluation results of the model
	Strength and toughness	The key index affecting the evaluation results of the model is second only to the pollution intensity of green building materials
	Pollution intensity	The key indicators affecting the evaluation results of the model are much more important than other factors
	Bearing capacity	Subsidiary indicators affecting the evaluation results of the model
Classification criteria for secondary evaluation	Pricing range	On the premise of the change of environmental protection evaluation standards, the pricing range of green building materials also changes
