19 January 2021, Webinar – Building airtightness improvements of the building stock- Analysis of European databases

Air infiltration in buildings has multiple consequences on energy use and indoor environmental quality. Therefore, in the last 10 years many countries have introduced requirements for building airtightness in their EP-regulation. Those requirements often prescribe that a test is performed by a qualified tester and that every test performed is recorded in a database.  Hundreds of thousands of data are now available in Europe.

Building airtightness: A critical review of testing, reporting and quality schemes in 10 countries

This report gives a critical review of steps taken in 10 countries (Belgium, Denmark, Finland, France, Germany, Netherlands, Japan, Sweden, UK, USA) with regard to testing and reporting schemes as well as overall quality approaches to improve building airtightness. The analyses are mostly based on contributions and discussions with 20 speakers invited to the AIVC-TightVent airtightness international workshop held in Brussels, 28-29 March 2012; they also include information from earlier publications as well as from the authors’ experience.

Methods and techniques for airtight buildings

This report gives an overview to the design principles and construction methods for building airtightness. Its primary objective is to disseminate basic information on steps to follow at design stage as well as on tightening products and frequent field issues.

It stems from the MININFIL project run between 2009 and 2010 under the PREBAT programme with the support of ADEME. In particular, it can be read as an introduction to the over 150 construction details developed within this project.
