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 … Continue reading →
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 … Continue reading →
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 … Continue reading →
The 2013 Conference of the Air Infiltration and Ventilation Centre, AIVC, was organized together with the 2nd Cool Roof Conference and the 1st Venticool Conference in Athens, Greece during September 2013. The theme of the Conference was ‘Energy Conservation Technologies for Mitigation … Continue reading →
Mandatory building airtightness testing has come gradually into force in the UK, France, Ireland and Denmark. It is considered in many other European countries because of the increasing weight of the building leakage energy impact on the overall energy performance … Continue reading →
