Requirements

Provide outdoor space greater than or equal to 30% of the total site area (including building footprint).

At least 25% of the required outdoor open space must be vegetated space planted with two or more types of vegetation or have overhead vegetated canopy.

The outdoor space must be physically accessible and be one or more of the following:

  • social area: a pedestrian-oriented paving or landscape area that accommodate outdoor social activities
  • recreational area: a recreation-oriented paving or landscape area that encourage physical activity;
  • diverse green space: a landscape area with two or more types of vegetation that provide opportunities for year-round visual interest;
  • garden: a garden space dedicated to community gardens or urban food production; or
  • habitat area: preserved or created habitat that meets the criteria of SS Credit Protect or Restore Habitat and includes elements of human interaction. These areas automatically meet the vegetation criteria of this credit.

Extensive or intensive vegetated roofs that are physically accessible can be used toward the minimum vegetation requirement, and qualifying roof-based physically accessible paving areas can be used toward credit compliance.

Wetlands or naturally designed ponds may count as open space if the side slope gradients average 1:4 (vertical:horizontal) or less and are vegetated. See all forum discussions about this credit »

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
