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

What is the maximum percentage of compliant building products that structure and enclosure materials can constitute for material disclosure and optimization?

1. 20%

2. 30%

3. 40%

4. 50%

The correct answer is: 30%

In the context of the LEED v4 potential for Material Disclosure and Optimization, the maximum percentage of compliant building products that structure and enclosure materials can constitute is indeed 30%. This specification emphasizes the need for transparency in material sourcing and the impact of building products on human health and the environment. LEED encourages the use of environmentally preferable products, and by limiting the percentage, it ensures that a diversity of materials is included, promoting a broader sustainable approach. It fosters innovation and the selection of products that not only contribute to performance but also possess lesser environmental impacts. This requirement aligns with the overall goal of the LEED framework, which is to minimize the environmental impact of the built environment through a holistic view of materials. The focus on 30% ensures that buildings utilize a variety of compliant materials without allowing any single type of material or product to dominate, thereby promoting sustainability and conscientious material usage.
