Workshop, Lund, March 16-17, 2015 – Voluntary and Regulatory Frameworks to Improve Quality and Compliance of ventilation and airtightness! The principal objective of this workshop is to discuss and identify ways to reduce these deviations with or without regulatory measures, thereby increasing the confidence in declared values of documents produced to show compliance with the regulations…. more

36th AIVC – 5th TightVent – 3rd venticool joint Conference in Madrid, Spain! The 36th AIVC conference: ‘Effective ventilation in high performance buildings’ will be held in the city of Madrid, Spain together with the 5th TightVent and the 3rd venticool conferences in September 23-24, 2015.

Accuracy of multi zone air leakage measurements

Researchers at Lawrence Berkeley National Laboratory have investigated the accuracy of using fan pressurization methods to determine leakage between adjacent zones, based on field measurements and simulations and comparing the uncertainty for the different measurements and calculation methods. The study also involved…Read more

Hands-on training for designers and craftsmen in France

The new French regulation (RT 2012, fully operational since January 2013) requires that the building airtightness of all new residential buildings be justified. This has led to over 100 000 tests performed every year, and of course, pressure on designers and craftsmen to address this issue. Because building airtightness entails practical challenges difficult to understand only in theoretical courses, several initiatives have grown to teach professionals how to achieve good airtightness in practice on building parts (windows, wall interfaces, duct penetrations, etc.)… Read more

Favorite Recent developments in TAAC

In September 2012, TightVent Europe set up the TightVent Airtightness Associations Committee (TightVent TAAC committee) aiming to bring together airtightness testers associations with the primary goal to promote reliable testing and reporting procedures.  Since then, the committee has met nine … Continue reading

Favorite Recent Belgian developments on quality frameworks for airtightness

The Flemish, Brussels and Walloon regions of Belgium have introduced the airtightness of buildings determined by fan pressurization tests in their regional Energy Performance (EP) regulations. Airtightness testing is not mandatory; however, when using the result of an airtightness test instead of the default air permeability value (for heating calculation)  = 12 m3/ (h.m2), a substantial improvement in energy performance can be achieved…Read more

Favorite 16-17 March 2015, Workshop, Lund – “Ventilation and Airtightness in Buildings : Voluntary and Regulatory Frameworks to Improve Quality and Compliance”

The international workshop on “Ventilation and Airtightness in Buildings : Voluntary and Regulatory Frameworks to Improve Quality and Compliance” will be held in Lund, Sweden on March 16-17, 2015. One topic of specific attention will be schemes implemented in various countries to increase the confidence in airtightness test results used in energy performance certificates and to improve the quality of the works. Discussions will be based on analyses of lessons learnt from field data.

This workshop is a joint initiative from: the QUALICHeCK consortium (http://qualicheck-platform.eu), AIVC (Air Infiltration and Ventilation Centre, www.aivc.org), TightVent (Building and Ductwork Airtightness Platform, www.tightvent.eu) and venticool (the international platform for ventilative cooling, www.venticool.eu).
