Inquiry

The LEED Calculator reads: "1. First, determine which regularly occupied areas are considered to be perimeter rooms and which are considered to be non-perimeter rooms. Using the floor plans for your project, superimpose an offset line 15 feet off of the exterior walls. The rooms that are entirely within the region between the exterior wall and the offset line are considered to be perimeter rooms. Those rooms that are not within this region or are intersected by the offset line are non-perimeter rooms." The LEED Reference Guide page 257 defines the perimeter as, "all regularly occupied areas that are 15 fee or less from a perimeter wall, either in whole or in part." I would think that the definition in the LEED Calculator is correct as rooms that extend beyond the 15 foot perimeter are generally large rooms with relatively limited exterior exposure and should not be considered perimeter rooms. Please confirm.
