T/UNP 516-2025 Green building materials evaluation specifications
Basic Information
Scope
Main technical content: This standard specifies the principles of green building material evaluation, grade classification, evaluation objects, indicator requirements, evaluation methods, and determination rules, and is applicable to green building material evaluation activities. The standard follows the principles of fairness, science, and operability, and divides green grades into one to three stars. Single-type building materials produced by the same enterprise, the same production base, and the same process are used as evaluation objects. The evaluation indicators cover both the production process and product performance. The production process involves requirements such as environmental protection and management systems, and the product performance evaluates different types of building materials by sub-indicators of energy attributes and quality attributes. The evaluation is carried out through methods such as checking data and reports. If the corresponding requirements are met, the materials can be determined as green building materials.
