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.
