Which LEED knowledge domain guides the sustainable sourcing of materials and waste management?

• A. Indoor Environmental Quality
• B. Energy and Atmosphere
• C. Materials and Resources
• D. Regional Priority

Answer: (C)

The idea being tested is which LEED domain governs where materials come from and what happens to them at the end of their life. Materials and Resources is the domain that centers on the life-cycle impacts of materials, guiding how products are sourced responsibly and how waste generated during construction and operation is managed. It covers sustainable sourcing, product transparency, and diversion of waste through reuse, recycling, and responsible end-of-life handling, with credits like building product disclosure/optimization and construction waste management.

Indoor Environmental Quality focuses on the indoor environment and occupant conditions such as air quality, lighting, and comfort; Energy and Atmosphere concentrates on energy performance and system efficiency; Regional Priority addresses location-based credits.
