Why it matters
A sustainable roofing zone may use solar panels, planted roofing, or both, subject to the applicable exclusions and exceptions. The design team should determine coverage from the actual scope and code requirements, not from the building’s gross roof area alone.
In practice
A project example
A developer incorporates the required roof strategy during schematic design so mechanical equipment and access routes do not consume space assumed available for solar or planting.
