SS Credit: Open Space

Open space is not about how much land is leftโ€”itโ€™s about how well it is used.

ย What is the Intent of this Credit?

The goal is to:

๐Ÿ‘‰ create accessible outdoor space that:

  • encourages interaction with nature
  • supports social interaction
  • promotes physical activity

๐ŸŽฏ Big Picture

Open space is not leftover spaceโ€”it is intentional, usable space.

๐ŸŒ Why This Matters

Open spaces provide:

๐Ÿ‘ฅ Human Benefits

  • improved well-being
  • increased productivity
  • opportunities for recreation

๐ŸŒฑ Environmental Benefits

  • habitat creation
  • urban biodiversity
  • rainwater infiltration
  • reduced heat island effect

๐Ÿ“ Core Requirement (VERY IMPORTANT)

โœ… Total Open Space Requirement

๐Ÿ‘‰ Provide:

๐Ÿ‘‰ โ‰ฅ30% of total site area

(including building footprint)

๐ŸŒฟ Vegetation Requirement

๐Ÿ‘‰ Of that open space:

๐Ÿ‘‰ โ‰ฅ25% must be vegetated OR have canopy

โš ๏ธ Important Rule

๐Ÿ‘‰ Turf grass does NOT count as vegetation

๐ŸŽฏ Memory Trick

  • 30% = total open space
  • 25% = vegetated portion

๐Ÿ“ Where Can Open Space Be Located?

๐Ÿ‘‰ Open space can be:

  • adjacent to building
  • elsewhere on site (master plan)
  • shared across development

๐Ÿ’ก Shared Space Insight

๐Ÿ‘‰ Shared open space:

  • can count toward compliance
  • must still meet usability criteria

๐Ÿงฉ What Qualifies as Open Space? (HIGHLY TESTABLE)

๐Ÿ‘‰ Open space must be:

๐Ÿ‘‰ physically accessible

AND include at least one of the following:

๐Ÿ‘ฃ 1. Pedestrian-Oriented Space

  • seating areas
  • plazas
  • gathering areas

๐Ÿƒ 2. Recreation-Oriented Space

  • fitness areas
  • play areas
  • sports spaces

๐ŸŒธ 3. Garden Space

  • diverse vegetation
  • year-round interest

๐ŸŒฝ 4. Community Gardens

  • urban agriculture
  • food production

๐ŸŒฟ 5. Habitat Areas

  • restored or preserved habitat
  • must align with Habitat credit
  • must allow human interaction

๐ŸŽฏ Exam Insight

Open space must be:
๐Ÿ‘‰ usable + accessible + intentional

๐ŸŒŠ Special Conditions

๐Ÿธ Wetlands & Ponds

๐Ÿ‘‰ Can count if:

  • vegetated
  • side slope โ‰ค 1:4 (vertical:horizontal)

๐Ÿข High-Density Projects (FAR โ‰ฅ 1.5)

๐Ÿ‘‰ May include:

  • vegetated roofs (for vegetation requirement)
  • accessible roof areas (for open space)

โš ๏ธ Conditions:

  • must be physically accessible
  • must support human use

โš ๏ธ What Does NOT Qualify

โŒ Non-Usable Spaces

  • narrow strips of turf
  • leftover landscaping
  • decorative-only areas

โŒ Artificial Turf

๐Ÿ‘‰ Does NOT count as:

  • vegetation
  • open space

๐Ÿ’ก Design Considerations

๐Ÿ‘‰ Open space should be:

  • appropriate for climate (e.g., xeriscape in arid regions)
  • designed for actual use
  • integrated with site design

๐ŸŒฟ Example:

  • shaded seating in hot climates
  • wind-protected areas in cold climates

๐Ÿง  Where People Get Confused

โŒ Misconception 1:

โ€œAny landscaping countsโ€

๐Ÿ‘‰ No
๐Ÿ‘‰ Must be:

  • usable
  • accessible

โŒ Misconception 2:

โ€œTurf grass counts as vegetationโ€

๐Ÿ‘‰ No

โŒ Misconception 3:

โ€œDecorative spaces qualifyโ€

๐Ÿ‘‰ No
๐Ÿ‘‰ Must support:

  • social or physical activity

โŒ Misconception 4:

โ€œOpen space must be ground-levelโ€

๐Ÿ‘‰ No
๐Ÿ‘‰ Roof spaces can qualify (if accessible)

Why does LEED require open space to be usable, not just available?
Because:
โ€ข usability drives human interaction
โ€ข improves well-being and activity
โ€ข ensures real benefit, not just compliance
Why does LEED exclude turf grass from vegetation calculations?
Because:
โ€ข turf provides limited ecological value
โ€ข requires high maintenance (water, chemicals)
โ€ข does not significantly support biodiversity
