Agenda• 1) Why this meeting?• 2) Activities of your associations - Your expectations with a EU
network– Roll call of meeting participants, including presentation of your
association, its activities and motivations (5 min each maximum, you are welcome to use any material (PPT, brochures, etc.)
• 3) Overview of possible actions• 4) Prioritization of actions and expected outcomes• 5) Next meetings
– Internet meetings– Physical meetings
Why this meeting?• Clear trend towards more airtightness measurements
– e.g., in the UK since the gradual enforcement of the regulation regarding airtightness;
– in France, there are over 400 qualified testers whereas airtightness measurement used to be confidential in France up to 2007
– …• Common concerns:
– How to set up a competent tester scheme?– How to develop guidelines beyond EN 13829?– How to define calibration procedures for airtightness testing?– …
Why this meeting?• Currently no airtightness association at EU level• Several associations have expressed interest in
TightVent activities and use TightVent as a support for a EU forum
What is TightVent Europe?• The European Buildings and Ductwork
Airtightness Platform• Launched in January 2011• Objective:
– Facilitating exchanges and progress on building and ductwork airtightness issues, including the production and dissemination of policy oriented reference documents and the organization of conferences, workshops, webinars, etc.

Management structure
General objectives of this meeting• Know each others activities and needs• See if there is converging interest for conducting
specific actions
Airtightness associations• Partnership conditions until April 2013
– Memorandum of understanding to be signed between associations and TightVent
– No charge until April 2013• After April 2013, to be discussed with the
interested parties• Not limited to EU associations
Activities of your associations• Belgium
– No network in Belgium yet, however, strong interest in the initiative because there is no requirement on the qualification of the testers
– Expectations:• Share experience on competent tester schemes in view of developing one in the Belgium framework
• Czech Republic (see specific presentation)– 35 members (active airtightness testers)– Expectations:
• 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 share:• round-robin tests• development and analysis of a leakage database• implementation of EN 13829• development of a common test protocol
Activities of your associations• Denmark (see specific presentation)
– 1 certified companies, 10 in the pipeline (representing in total 15-20 testers)
– Expectations:
• Germany– Flib has 300 members (mostly testers)– Expectations:
• Database developments, XML output files, calibration, designers and craftsmen, etc.
Activities of your association• Sweden (see specific presentation)
– No certification for airtightness today but significant activity on guidance to developers, training and research (e.g., durability)
– Expectations• Competent tester schemes• Input to testers training• Database development• Development of requirements• Strategies when it comes to big buildings or testing a part of a building
• UK– Expectations
• Resolve challenges with regard to test reliability
Possible actions• Starting with simple actions
