The PFI access door can contribute directly to a project's ability to achieve LEED certification:
Note 1: Maximum door size 24" x 36" can also be calculated by multiplying the surface area of the door (24"x36"). The maximum surface area is 864 sq inches. The maximum height or width is 36". All door sizes equal or smaller than 864 sq inches fall within the standards. Ex. Door size of 28" x 28" = 784 sq inches.
