If your project has an ample amount of surrounding site area, this may be a straightforward credit for you. This credit encourages projects to not only set aside open space, but to ensure that it’s accessible and promotes outdoor recreation for building users.
An asphalt playground, however, won’t cut it. Teams must dedicate a percentage of the open space to vegetation. There are plenty of great options for outdoor recreation that can help you achieve this credit, so get creative with your site.
No. Open space, as defined by this credit, is an outdoor space that must be physically accessible and provide opportunities for outdoor recreation (see the LEED Reference Guide for specifics). Vegetation is the portion of this open space that is not paved or made up of turf grass.
Artificial turf can contribute to the open space areaOpen space area is usually defined by local zoning requirements. If local zoning requirements do not clearly define open space, it is defined for the purposes of LEED calculations as the property area minus the development footprint; it must be vegetated and pervious, with exceptions only as noted in the credit requirements section. Only ground areas are calculated as open space. For projects located in urban areas that earn a Development Density and Community Connectivity credit, open space also includes nonvehicular, pedestrian-oriented hardscape spaces., but you must ensure that your project also includes the required percentage of actual vegetation in order to earn the credit.
To create exterior open space that encourages interaction with the environment, social interaction, passive recreation, and physical activities.
Provide outdoor space greater than or equal to 30% of the total site area (including building footprintBuilding footprint is the area on a project site used by the building structure, defined by the perimeter of the building plan. Parking lots, parking garages, landscapes, and other nonbuilding facilities are not included in the building footprint.). A minimum of 25% of that outdoor space must be vegetated (turf grass does not count as vegetation) or have overhead vegetated canopy.
The outdoor space must be physically accessible and be one or more of the following:
For projects that achieve a density of 1.5 floor-area ratioThe density of nonresidential land use, exclusive of parking, measured as the total nonresidential building floor area divided by the total buildable land area available for nonresidential structures. For example, on a site with 10,000 square feet (930 square meters) of buildable land area, an FAR of 1.0 would be 10,000 square feet (930 square meters) of building floor area. On the same site, an FAR of 1.5 would be 15,000 square feet (1395 square meters), an FAR of 2.0 would be 20,000 square feet (1860 square meters), and an FAR of 0.5 would be 5,000 square feet (465 square meters).

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.
For projects that are part of a multitenant complex only
Open space can be either adjacent to the building or at another location in the site master plan. The open space may be at another master plan development site as long as it is protected from development. If the open space is not adjacent to the building, provide documentation showing that the requirements have been met and the land is in a natural state or has been returned to a natural state and conserved for the life of the building.
Has anyone tried using the area of a green wall to achieve the 25% vegetated space portion of this open space requirement?
Can balconies count as part of open space?
Hi, have you tried submit the balconies as part of open space?
Balconies can reasonably be included in open space calculations IF they meet the following:
1) Your project is in an urban area and is going to earn SSc2. From the reference guide "pedestrian-oriented hardscapeThe inanimate elements of the building landscaping. It includes pavement, roadways, stonewalls, wood and synthetic decking, concrete paths and sidewalks, and concrete, brick, and tile patios. can contribute to credit compliance. For such projects, a minimum of 25% of the open space counted must be vegetated."
2) Balconies or pedestrian-oriented hardscape areas must be accessible by all FTEFull-time equivalent (FTE) represents a regular building occupant who spends 8 hours a day (40 hours a week) in the project building. Part-time or overtime occupants have FTE values based on their hours per day divided by 8 (or hours per week divided by 40). Transient Occupants can be reported as either daily totals or as part of the FTE. Residential occupancy should be estimated based on the number and size of units. Core and Shell projects should refer to the default occupancy table in the Reference Guide appendix. All occupant assumptions must be consistent across all credits in all categories. and provide "passive or active recreation opportunities."
