A calculation tool estimates air loss from HVAC ductwork systems. These tools utilize standardized methodologies developed by the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA) to determine the amount of air escaping from ductwork at specific pressure levels. This estimation is often presented as a percentage of total airflow or as a CFM (cubic feet per minute) value.
Accurate evaluation of duct system integrity yields numerous advantages. Reduced energy consumption, improved indoor air quality, and enhanced HVAC system performance are all direct results of minimizing unintended air losses. Historically, precise quantification of duct leakage was challenging, leading to inefficient systems. Standardized methods, promoted by SMACNA, provide a more reliable and consistent approach, enabling better system design and commissioning.
