SMACNA Issues Fifth Edition of HVAC Systems Duct Design Manual

The Sheet Metal and Air Conditioning Contractors’ National Association published the fifth edition of its HVAC Systems Duct Design Manual, which is available digitally and in print. This edition presents the methods and procedures for properly designing an HVAC air distribution system, with new detailed information on duct design, duct fitting selection, examples, calculations and tables.

In addition to the basic engineering principles for the sizing of HVAC ductwork systems, the manual also provides detailed information on: air distribution materials; methods of construction; economics of duct systems; duct system layout; fan selection; duct leakage; acoustic considerations; and testing, adjusting, and balancing.

The updated 404-page standard was revised to provide contractors, designers and facility owners with the information needed to apply effective and efficient solutions to their projects. For more information, visit smacna.org/resources/technical/technical-standards.
