The LEED guide in the perimeter area explanation section says:  "Below-grade walls with areaways and walls that abut adjacent buildings are excluded". I have some questions about this statement as follows:

  • Spaces within the perimeter area next to the below grade walls are excluded from the 75% requirement?
  • May I exclude a section of the floor plate area from the minimum perimeter area calculation if it is adjacent to below grade walls? Which portion would I be able to extract?
