The Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA), aleader in promoting quality and excellence in the sheet metal and air conditioning industry, released two new standards to the industry. 

First is the 2^nd edition of the Kitchen Ventilation Systems and Food Service Equipment standard.  This standard continues to serve as a reference guide to industry-accepted practices for the fabrication and installation of commercial kitchen ventilation systems, as well as custom-built food preparation and serving equipment. It assists designers, contractors, and code officials in understanding the complexities of designing, installing, constructing, and balancing the exhaust and make-up air systems required for commercial kitchen ventilation. This edition was developed in accordance with NSF/ANSI 2: Food Equipment, the latest applicable codes, and recognized industry standards.

Also released was the HVAC Duct Design Guide (5^th Ed.) in Spanish. The manual presents the methods and procedures for designers to properly design an HVAC air distribution system, as well as 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, pressure losses, fan selection, duct leakage, acoustic considerations, and Testing, Adjusting & Balancing.

“Our association is committed to compiling, updating, and validating the highest standards for our industry and the clients they serve,” said Eli Howard, SMACNA’s chief operations officer. Free copies are available to SMACNA members, and they are available for purchase by other members of the industry.

Technical standards and manuals developed by SMACNA members have worldwide acceptance by the construction and code community, as well as local and national government agencies. SMACNA standards and manuals address all facets of the sheet metal and HVAC industry – including duct construction and installation, indoor air quality, energy recovery, roofing and architectural sheet metal, welding, and commissioning – and advancements are made possible by those in the industry who provide suggestions for improvement based on knowledge, experience, and research. All of SMACNA’s standards manuals are available via SMACNA’s online bookstore.
