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

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”

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...,)

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...
