What is the minimum percentage of total site area required for outdoor space?

In order to achieve a LEED credit for outdoor space under the Sustainable Sites category, projects are generally required to provide a specified minimum percentage of the total site area as usable outdoor space. This requirement promotes the benefits of outdoor environments for occupants, including improved health and well-being through access to nature and outdoor activities.

The minimum percentage stipulated for outdoor space in LEED BD+C projects is indeed 30%. This space should be designed to be usable and accessible, providing opportunities for various types of outdoor activities, which can contribute to the overall quality of life for building occupants.

Designing outdoor spaces also encourages biodiversity and increases the site’s ecological value. By adhering to this percentage, projects are more likely to support sustainable practices, such as stormwater management and habitat preservation. Therefore, ensuring that 30% of the total site area is allocated to outdoor space aligns with LEED’s sustainability goals.
