I came across some interesting info about building codes in Dade county, FL:
"I first heard of the Dade County Blues last year while chatting with a couple distributors from Florida. These gents explained to me that the Miami-Dade County Building Code Compliance Office requires that every product to be used in new home construction be put through a rigorous screening process before it can be approved for use on the house." [Because of hurricanes] Andrew & Stacy go on to wonder if this could happen elsewhere in regard to green building.
