1. A.BD.CZ Association of Czech airtightness test providers Jiří Novák Czech Technical University, Prague

2. situation Jiří Novák | April 2011 2009: approx. 5 airtightness test providers in CZ launch of state subsidies for construction of passive houses new construction – financial support bound up with a succesfull airtighnes test expected rise of the number of test providers need of quality control

3. foundation of A.BD.CZ Jiří Novák | April 2011 July 2009: Asociace Blower Door CZ founded (A.BD.CZ) “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” www.asociaceblowerdoor.cz July 2010

4. goals of A.BD.CZ Jiří Novák | April 2011 supervision and quality control of the professional activities of the members support of knowledge exchange and lifelong learning of the members development of measuring procedures and their implementation cooperation with state authorities

5. members of A.BD.CZ Jiří Novák | April 2011 35 members 19 mesuring devices membership open to every active airtightness test provider observation of ethical code required violations of ethical code – disciplinary procedure

6. foregoing activities Jiří Novák | April 2011 common protocol of test results for the purpose of Green Savings programme (subsidies for PH) definition of general conditions of the test (state of the building at the moment of the test)

7. ongoing activities Jiří Novák | April 2011 general meetings with workshops round-robin tests (2010, 2012) collection of test results development and analysis of a leakage database

8. planned activities Jiří Novák | April 2011 certification of members commentary of EN 13829 (common interpretation)

9. EU network - motivation / expectations Jiří Novák | April 2011 motivation −need of information exchange (learning from good examples, successful approaches...) −contribute, support this information exchange

10. EU network - motivation / expectations Jiří Novák | April 2011 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...,)

11. 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

12. thank you...
