The feasibility of good air-tightness in new buildings can be determined based on the obtained air tightness classes as defined in EN 12237.

Jeroen Soenens and Pedro Pattijn

Portugal introduced, for the first time, in the 2006 Building Regulations, a requirement on the airtightness of the ductwork in new HVAC installations. A test is required during commissioning.
