25 January 2018 | "Ductwork airtightness: Standardisation’s on- going work and an overview of status and trends in Sweden, Japan, Spain and Portugal"



Work performed so far in the field of ductwork airtightness has shown that it may lead to important energy losses and increased fan energy use. Nevertheless, a recent survey has shown that ductwork airtightness does not seem to be taken into account (neither in regulation nor in energy performance programmes) in most European countries. Progress is therefore needed to better understand the impact of ductwork airtightness on energy use (fan, cooling and heating) and indoor air quality.



The objective of this webinar was:




  • to demonstrate the importance of ductwork airtightness;

  • to give information on standardisation's on-going works at CEN and ISO on this subject ;and

  • to give an overview of status and trends in Sweden, Japan, Spain and Portugal.



This webinar was organised with the support of TightVent Europe (www.tightvent.eu)  and  AIVC.  Both initiatives are facilitated by INIVE (www.inive.org).
