Building thermography 360 pages ebook- with information related to airtightness testing

The handbook: “Building Thermography-including blower door and heat flux meter”  approaches the technique both from a theoretical and practical point of view. It includes one chapter dedicated to the technical characteristics of thermal cameras and software, two chapters dedicated to blower door test and its synergy with thermography with an explanation of standards and case histories and a final chapter which treats heat flux meter and measuring of thermal transmittance in situ.

LBNL paper on 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 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
