Formulas Used

Total LEED Points

total = total_points

Energy Category Achieved

energy_pct = energy_points / 35 * 100

Maximum Possible

max_possible = 110

Points to Next Level

to_next_level = total_points < 40 ? 40 - total_points : (total_points < 50 ? 50 - total_points : (total_points < 60 ? 60 - total_points : 80 - total_points))

How It Works

How to Estimate LEED Points

LEED (Leadership in Energy and Environmental Design) rates buildings on a 110-point scale.

Certification Levels

  • Certified: 40-49 points
  • Silver: 50-59 points
  • Gold: 60-79 points
  • Platinum: 80+ points

    • Point Categories

  • Energy & Atmosphere: 35 points max
  • Sustainable Sites: 28 points max
  • Indoor Environmental Quality: 17 points max
  • Materials & Resources: 14 points max
  • Water Efficiency: 11 points max
  • Innovation & Regional: 10 points max

    • Worked Example

    A building project scoring across all LEED categories.

    2. 02Water: 8 points
    3. 03Materials: 7 points
    4. 04Indoor quality: 10 points
    5. 05Sites: 12 points
    6. 06Innovation: 5 points
    7. 07Total: 20 + 8 + 7 + 10 + 12 + 5 = 62 points (LEED Gold)
