Hello,
Does anyone know how to interpret "no more than 45 degrees" of exception 5.b - table G3.1 (90.1-2007/2010/2013) ? :
5. Building Envelope
All components of the building envelope in the proposed design shall be modeled as shown on architectural drawings or as built for existing building envelopes.
Exceptions:
b. Exterior surfaces whose azimuth orientation and tilt differ by no more than 45 degrees and are otherwise the same may be described as either a single surface or by using multipliers.
Because "no more than 45 degree" include 45 degree, does the exception still apply if the azimuth of two walls is exactly 45 degrees?
In other words, considering a LEED project, can a perfect octagonal building shape be modeled as a square building (as long as they have the same floor area and the 8 walls have a similar construction) ?
Thanks
Julien
