The airtightness track at the AIVC 2017 conference consisted of 23 presentations organised in 5 sessions of which 3 were topical sessions with a number of invited presentations. Most of the airtightness topics in the call for papers for the … Continue reading
New Zealand homes and apartments have become more and more airtight and have reached a level of airtightness that requires dedicated ventilation. Despite the fact that there is no airtightness requirement in the New Zealand Building Code, new homes regularly … Continue reading
Eurovent Certita Certification is pleased to announce the launch of a new certification programme for Ventilation Ducts (DUCT). The DUCT programme has been developed in 2015-2016 with the support of a dedicated launching committee. The first release of the Operational … Continue reading

The “ASHRAE HVAC Duct Sizer” application designed by Carmel Software Corporation for ASHRAE, allows the user to quickly size one HVAC duct run or a range of duct sizes using the constant friction method. In the “Size by Airflow” mode, … Continue reading
The 7th TightVent conference will be held on 18 and 19 September 2018 in Juan-les-Pins, France together with the 39th AIVC conference and the 5th venticool conference. More information will follow soon so stay tuned.
The Air Infiltration and Ventilation Centre (AIVC) has released a new Contributed Report (CR#16) , including 23 factsheets specifically related to ventilation and airtightness issues, field data, and solutions, delivered in the framework of the EU QUALICHeCK project.
The report is now available at: http://aivc.org/resource/cr-16-towards-compliant-building-airtightness-and-ventilation-systems
A new Ventilation Information Paper (VIP), has been released by the Air Infiltration and Ventilation Centre (AIVC), which analyses both the policy instruments used (regulatory requirements and incentives, specific programme requirements, quality frameworks for testers and builders) and the changes observed in practice in terms of building and ductwork airtightness over the past 5 years, using as reference mostly publications from AIVC and TightVent Europe led events.
The review begins with the motivations for improving building airtightness, including energy use impacts, building durability, indoor air quality (IAQ) impacts, and safety of occupants. Mandatory building airtightness testing has come gradually into force in the United Kingdom, France, Ireland and Denmark. It is also considered in many other European countries, either as regulatory or programme requirements, mostly because of the increasing weight of building leakage energy impact on the overall energy performance of low-energy buildings. Because of legal and financial issues due to wrong tests, several countries have developed qualification schemes for building airtightness testers and also airtightness databases that prove to be very useful for monitoring policies and building stock.
As for ductwork airtightness, this issue is rarely addressed despite significant energy savings and/or IAQ impacts associated. The feedback as well as energy and IAQ analyses of the recently introduced Effinergie requirements in France would be very helpful to make progress on this issue.

The final programme for the 38th AIVC – 6th TightVent – 4th venticool conference: “Ventilating healthy low-energy buildings” has been released. The joint conference, co-organized by the International Network on Ventilation and Energy Performance (INIVE), on behalf of the Air Infiltration and … Continue reading
