SS Credit: Heat Island Reduction

Option 1: Non-roof
  • Ensure that the hardscape areas are consistent with other credits. Be sure that the tree-shaded area is calculated as the 10-year canopy width at noon (i.e., in plan view, plant canopy width has no extending shadows regardless of time of year). Any given surface area may only be counted in the calculations once, even if it is addressed through multiple strategies.
Option 2: Roof
  • Note that LEED Interpretation 10235 (exempting functional space such as helipads) is not applicable to O+M v4. It can only be applied to v2009.
Option 3: Non-roof and Roof
  • Be sure that all areas are included in the calculations, even if the non-roof or roof materials do not meet the requirements.
Option 4: Parking under cover
  • Ensure that all parking areas that are under the same management control as the building and that directly support the operations of the project building are included in the LEED project boundary and the calculations for this credit.
  • Ensure that the number of parking spaces is consistent with the number of parking spaces stated within other credits. Include motorcycle parking in this value, but exclude bicycle parking.
