Measures operational efficiency, including water use, energy consumption, and waste management. What is NSF/ANSI 347

Prior to NSF/ANSI 347, specifying a sustainable roofing membrane was challenging. Specifiers had to choose between various single attributes, such as durability, low VOCs, or recyclability, without a comprehensive, multi-attribute assessment. This led to the development of a standard that evaluates a product's entire life cycle, from raw material extraction to end-of-life management.

This section focuses on reducing the environmental impact of the manufacturing facility itself, covering energy consumption, water usage, waste management, and greenhouse gas emissions during the production of the membrane. 3. Membrane Durability such as durability

This section forms the foundation of the assessment by analyzing the inventory of ingredients used to manufacture the membrane. Points are awarded based on:
