LEED BD+C: Healthcare | v3 - LEED 2009

Site development - maximize open space

SSc5.2 | Possible 1 point

Intent

To promote biodiversity by providing a high ratio of open space to development footprint.

Requirements

Case 1

Reduce the development footprint1 and/or provide vegetated open space within the project boundary such that the amount of open space exceeds local zoning requirements by 25%.

OR

Case 2

For areas with no local zoning requirements (e.g. some university campuses, military bases), provide a vegetated open space area adjacent to the building that is equal in area to the building footprint.

OR

Case 3

Where a zoning ordinance exists, but there is no requirement for open space (zero), provide vegetated open space equal to 20% of the project site area.

All cases

For projects in urban areas that earn SS Credit 2: Development Density and Community Connectivity, vegetated roof areas can contribute to credit compliance.

For projects in urban areas that earn SS Credit 2: Development Density and Community Connectivity, pedestrian-oriented hardscape areas can contribute to credit compliance. For such projects, a minimum of 25% of the open space counted must be vegetated.

Wetlands or naturally designed ponds may count as open space and the side slope gradients average 1:4 (vertical: horizontal) or less and are vegetated.
