What is the proper application of an alternative solution in building design?
When a design differs from the acceptable solutions in division b, then it should be treated as an alternative solution.
A proponent of an alternative solution must demonstrate that the solution addresses the same issues as the applicable solution in Div B. Claus 1.2.1.1 (1)b identifies the principal that div B establishes quantitative performance targets that alternative solutions must meet.
An effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions. An applicable, acceptable solution is any solution which respects its respective NBC statements
