Duct leakage is detrimental to indoor air quality (IAQ), comfort, and energy efficiency. It is often accompanied by other problems, such as inferior commissioning and cleaning. Airtight circular (round) ductwork is known to have many other benefits over rectangular ductwork, including cost. But why do designers, installers, and building owners forego airtight duct systems- It is due to: (i) lack of awareness of the benefits, (ii) lack of performance requirements and penalties for noncompliance, and (iii) no one is found accountable, as there is no commissioning.

Finland has set minimum requirements in the National Building Code for thermal insulation and ventilation of new buildings since 1976. The requirements have been changed several times in order to improve energy efficiency in buildings. The changes have been made in 2003, when the level of the requirements was tightened by 25-30%, and in 2007, when the requirements were changed because of the implementation of the EPBD. The latest tightened (-30%) requirements were given on December 2008 and will come into force in the beginning of 2010.
