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

What percentage of open space must be vegetated to meet LEED requirements?

1. 20%

2. 25%

3. 30%

4. 35%

The correct answer is: 25%

To meet LEED requirements, at least 25% of open space must be vegetated. This standard aligns with LEED’s emphasis on promoting environmental stewardship and enhancing biodiversity through the use of landscape elements. Vegetated open space can help reduce heat island effects, improve air quality, provide habitats for wildlife, and support stormwater management by increasing the permeability of the site and reducing runoff. The requirement for vegetated open space is part of the Sustainable Sites Credit category, which encourages practices that lead to more ecologically beneficial landscapes. By ensuring that a minimum percentage of open space is vegetated, LEED drives projects to incorporate natural elements that contribute positively to the environment and improve the overall quality of life for occupants and surrounding communities. This standard reflects a growing recognition of the importance of green spaces in urban and suburban settings.
