Since 1949, the Qualibat association is a qualification and certification body for construction companies. Qualibat is accredited by Cofrac. More than 70 000 workers are qualified or certified by Qualibat.   In 2011, Qualibat launched qualification "8711" for building airtightness testers. Almost 1000 testers have been qualified since then.   In 2014, Qualibat launched qualification "8721" for ductwork airtightness testers. Since then, around 70 testers have been qualified.

In 2007, the Effinergie association launched its first label “BBC-Effinergie” for new buildings, requiring a primary energy use of 50kWh/m² per year. The label was very successful and became mandatory for all new buildings under the 2012 Energy Performance regulation (RT2012).    When the RT2012 came into force, Effinergie launched its new label "effinergie +"   The “effinergie +” label requires (among others):

The Independent AirTightness Testing Scheme (iATS) is a scheme created for companies (including sole traders and partnerships) that carry out air tightness testing activities and to provide reassurance to clients that the work is carried out to a high degree of quality and integrity.   iATS is authorised to operate as a Competent Persons Scheme (CPS) for air tightness testing, effective from 18 April 2015.   If you would like more information about the scheme, please click on the link provided below.

A recent survey amongst experts of the TightVent Airtightness Committee revealed changes in regulatory building airtightness requirements in 6 out of 10 countries since 2011 as well as significantly growing awareness. These are positive signs that should be reinforced with quality assurance measures to reduce the risk of discrepancies between claimed or expected and actual performance. Several good examples of such measures have been documented in the QUALICHeCK project and could serve as inspiration for other parties.

La ventilation influence le calcul du niveau E dans les réglementations régionales sur la performance énergétique des bâtiments (PEB). La présente Infofiche examine les possibilités de diminution de ce niveau, tant pour le résidentiel que pour le non-résidentiel. Elle s'adresse au responsable du calcul PEB et à l'auteur de projet, mais également aux entrepreneurs concernés par la ventilation afin de les aider à convaincre sur le choix de solutions énergétiquement efficaces.   Sommaire de cette infofiche:

We spend up to 90% of our lives indoors. Yet the air quality inside buildings has been shown to be 2 to 5 times poorer than outdoors. This can also true for modern energy efficient buildings due to increased insulation levels and greater air tightness.
