  4. 4. Conclusions from Brussels June 2011 workshopIt seems very useful to have international collaboration on the topic of building and ductwork airtightnessThe European countries have a common challenge which justifies a common platformImportant to have a platform in which all stakeholders can participate  Launch of TightVent Europe Website www.tightvent.eu 4

  10. 10. ConclusionsBuilding and ductwork airtightness is one of the key challenges for the futureTightVent Europe has the ambition to be the meeting place for airtightness issues in close collaboration with all relevant initiativesIn particular building airtightness is a complex issue since it involves nearly all stakeholders and complex liability and cost issuesAn ingelligent and pragmatic framework for compliance is CRUCIAL! 10
