  1. A LEED project team is tracking construction waste. They generated 100 tons of waste and diverted 65 tons through recycling. What is their diversion rate?

    Answer: 65%

    Diversion rate = (diverted waste ÷ total waste) × 100 = (65 ÷ 100) × 100 = 65%.

  2. Which of the following is considered 'pre-consumer' (also called 'post-industrial') recycled content?

    Answer: Fly ash from coal combustion used in concrete

    Pre-consumer (post-industrial) recycled content includes manufacturing byproducts diverted from waste streams before they reach consumers — fly ash from power plants is a classic example.

  3. In LEED v4, the 'Interiors Life Cycle Impact Reduction' credit for interior projects rewards teams that reuse existing building elements. Which element would qualify as a reused interior component?

    Answer: An existing raised access floor system retained from a previous tenant

    Reusing existing interior elements — such as raised floor systems, interior walls, doors, or ceiling systems — avoids the manufacturing impacts of new materials and counts toward life cycle impact reduction.

  4. What LEED credit category specifically addresses the potential for materials to release harmful chemicals during a building's operational phase?

    Answer: Indoor Environmental Quality — Low-Emitting Materials

    Low-Emitting Materials is an Indoor Environmental Quality credit that limits VOC emissions from installed products to protect occupant health after the building is occupied.

  5. Under LEED v4's Construction and Demolition Waste Management credit, which of the following must a project team document?

    Answer: The total weight or volume of waste generated and the diversion rate achieved

    LEED requires documentation of the total waste generated and the percentage diverted from landfill through recycling, reuse, or composting to verify credit compliance.

  6. Which strategy would contribute most directly to achieving LEED's 'Building Life-Cycle Impact Reduction' credit?

    Answer: Reusing an existing historic building structure rather than demolishing and rebuilding

    Reusing an existing building's structure and envelope is the most impactful strategy for this credit because it avoids the embodied carbon and resource use associated with new construction materials.

  7. Under LEED v4, what is the minimum number of permanently installed building products needed to earn points under the Building Product Disclosure and Optimization credits?

    Answer: 10 different permanently installed building products

    LEED v4 requires at least 20 different permanently installed products meeting the credit criteria to earn one point under most Building Product Disclosure and Optimization credits.
