IMC Code Change Update The 2009 code change that required 28 gauge residential sheet metal ducts has been reversed in the 2015 International Mechanical Code (IMC). This press release adds some detail to the announcement.
The Green Impact of Efficient Duct Design An Aug 2009 article published in the RSES Journal, authored by Chris Van Rite presents – Proper sizing and installing ductwork can make an HVAC system and the system owner “green” in more ways than one.
Air Flow is Critical To HVACR System Performance, An April 2008 article published in the RSES Journal, authored by Chris Van Rite presents Understanding the benefits–and drawbacks–of flex ductwork are critical to creating efficient HVAC systems.
Static Pressure Losses in 6”, 8”, and 10” Non-Metallic Flexible Duct A Texas A&M study measured airflow static pressure losses through non-metallic flexible ducts.
Changes Relating to January 23, 2006 NAECA Update The National Appliance Energy Conservation Act (NAECA) of 1987 established among other things minimum Seasonal Energy Efficiency Rating (SEER) for A/C equipment. The minimum SEER required by NAECA since 1992 has been 10 SEER. On January 23rd, 2006 the NAECA minimum SEER increased to 13 SEER.
