SMACNA together with ASHRAE is developing a new standard that will contain test procedures and requirements for total HVAC system air leakage in commercial buildings. This activity is needed because as much as one third of a system's airflow can leak through the air distribution system, which in turn causes a loss of comfort and heating or cooling capacity. System air leakage also significantly increases air conditioning and heating bills, and can contribute to indoor air quality problems. This seminar focuses on the benefits and costs of performing system leakage tests from the perspective of a TAB contractor, an association of sheet metal contractors, and researchers. Steps needed to achieve widespread reductions in leakage and improved air-handling system efficiency are also presented.
