Which organizations commonly provide standards used to meet LEED credit requirements?

• A. National Electrical Code
• B. ASHRAE, ASTM, and EPA
• C. ISO 9001
• D. OSHA

Answer: (B)

LEED credits are built around performance standards from respected technical bodies that focus on how buildings operate and perform. ASHRAE provides the core standards for energy use and indoor air quality, with examples like energy and ventilation requirements that many credits reference. ASTM covers a wide range of material and product standards that support credits related to sustainable materials, durability, and performance. EPA contributes environmental benchmarks and programs such as Energy Star and other environmental guidance that inform credits on energy and water efficiency and overall environmental impact. Together, these organizations supply the standards that LEED relies on to define what qualifies for credits.

Elements like the National Electrical Code, ISO 9001, or OSHA aren’t the primary sources LEED credits draw from for building performance requirements. NEC focuses on electrical safety, ISO 9001 on quality management, and OSHA on workplace safety; while important in their domains, they aren’t the standard set LEED mainly uses to meet credit requirements.
