“a voluntary, non-political, professional association of persons performing the measurements of building airtightness by means of the fan pressurization method or derived methods and promoting a complex quality of buildings, particularly the reduction of energy consumption due to the limitation of their air permeability”

• motivation
− need of information exchange (learning from good examples, successful approaches...)
− contribute, support this information exchange
• expectations (role of the EU network)
− gathering the information about the approaches adopted in different countries to deal with selected issues („summary tables“)
− gathering detailed information concerning main issues (conference / workshop papers, leakage data...)
− facilitate a homogenous testing practice - common approaches or guidelines (e.g. structure of test protocol, of a lekage database training...,)
we can offer...
Jiří Novák | April 2011
• experience with:
− round-robin tests
− development and analysis of a leakage database
− implementation of EN 13829
− developpment of a common test protocol
thank you...
