LEED AP Building Design and Construction (BD+C) Practice Exam

What is the minimum percent reuse required for building and material reuse?

1. 10%

2. 25%

3. 50%

4. 70%

The correct answer is: 25%

The minimum percent reuse required for building and material reuse in the context of LEED certification is indeed 25%. This requirement is part of the LEED framework, which aims to encourage sustainable building practices through the repurposing of existing materials and structures. By mandating a minimum reuse percentage, LEED promotes the reduction of waste and resource consumption associated with new construction projects. Achieving this 25% threshold supports the larger goals of sustainability, including minimizing environmental impacts, conserving natural resources, and reducing carbon emissions associated with manufacturing new building materials. This reuse can be accomplished through various practices, such as incorporating salvaged materials, reusing structural elements from existing buildings, or renovating rather than demolishing old structures. By focusing on this level of reuse, projects can also potentially qualify for points under the LEED rating system, further incentivizing sustainable design and construction practices.
