Hi
I have a question about this description: pedestrian-oriented hardscape areas can contribute to credit compliance. For such projects, a minimum of 25% of the open space counted must be vegetated.
In this case pedestrian-oriented hardscape should be EQUAL to 20% of the project's site area and then minimum of 25% of the open space counted must be vegetated (even if I have more hardscape area I only count for LEED 20% of site area)
OR
I count total pedestrian-oriented hardscape on project site and then I try to achieve 25% vegetation?
example:
site area: 10 000 sf
required pedestrian-oriented hardscape area: 10 000 * 0.2 = 2000 sf
min. vegetated open space: 2000 * 0.25 = 500 sf
or
total pedestrian-oriented hardscape area on site: 5000 sf
min. vegetated open space: 5000 * 0.25 = 1250 sf
Thanks

The 25% is relaive to the pedestrian-oriented hardscape, not the whole site.

Hi Tristan, still confused. Which scenario is it for Michal's example? 500 sf or 1250 sf? I am faced with the same exact question. Knowing if Michal should use the 500 or the 1250 value will determine if I should or should not go for this credit. Thanks, Jay

Jay, there are two requirements that are being referenced. One is the percentage of the total site that must be open space. Then there is a percentage of open space that must be vegetated.The credit language at the top of the page breaks this down pretty well on a case by case basis. Let me know if there is still any confusion.

Hi All
I'm after Design Review and a second scenario is correct (we count vegetated open space from TOTAL pedestrian-oriented hardscape area (if we contribute pedestrian-oriented hardscape to credit compliance)):
total pedestrian-oriented hardscape area on site: 5000 sf
min. vegetated open space: 5000 * 0.25 = 1250 sf

Tristan: I think the question is that... Is it required to input all of the Open Space area provided into the calculation if the design has more than the 20% open space required?

If Michal's case is what the credit intend, that means the more the open space provided the more the vegetated area shall be provided?
However, referring to the Example 1 of the reference guide, look like the required vegetated area shall be (Total site area)*30%*25%?
