Topic
Duct Construction

Question

Is it the intent of M1601.1 to require Florida Licensed Professional Engineers to use ACCA Manual D to size ductwork in residences, or may a PE use standard procedures as outlined by ASHRAE and typically used in commercial applications for sizing ductwork?

Answer Published 05/02/2017 at 8:30 AM

No, the Section cited specifically states "or other approved methods". There is no problem with accepting a design by ASHRAE, with careful evaluation a local authority could accept a manufacturer's program, but it would be a local determination.. If the jurisdiction where the referenced project is not accepting the manufacturer's program, that is fully within their authority.
