The credit is not applicable.
Additional Considerations
In some projects, a design team may find that the
overall open site area exceeds the local open space
requirement by 25 percent, but the amount of
landscape area must be increased (relative to the
hardscape area) to meet the LEED criteria. In
these situations, the increase in landscape area is
assumed to result in no cost increase, or a possible
cost decrease, as demonstrated in credit SS-5.1.
In some GSA projects (e.g., Courthouses) a
portion of the open site may be reserved for long-
term building expansion. If expansion is known to
be likely at a given site, the area of the open space
should be evaluated based on the expected post-
expansion site areas.
Synergistic Credits
