9 December 2020, Webinar – Resilient Ventilative Cooling in practice

The current development in building energy efficiency towards nZEB buildings represents a number of new challenges to design and construction. One of these major challenges is the increased need for cooling in these highly insulated and airtight buildings, which is not only present in the summer period but also in the shoulder seasons and in offices even in midwinter. Resilient ventilative cooling can be an energy efficient solution to address this cooling challenge in buildings.

21 February 2020, Webinar – Durability of building airtightness: Assessment through laboratory testing

Mandatory or voluntary building airtightness testing has come gradually into force in many European countries mostly because of the increasing weight of building leakage energy impact on the overall energy performance of low-energy buildings. Therefore, airtightness levels of new buildings have significantly improved in the last decade, but a lot of questions remain regarding the durability of airtightness products.

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.

25 April 2019, Webinar – Ductwork airtightness measurements: protocols

Various studies have shown that ductwork leakage has a major impact on energy use (i.e. increased fan energy use, heating & cooling losses etc.). However, in most European countries, it is not common to perform ductwork airtightness tests, which is probably due to the lack of awareness on the consequences of ductwork leakage. As follows, ductwork airtightness is not properly taken into account in most Energy Performance Regulations and Calculations.

8 October 2013, Webinar - Building Airtightness Solutions: System approach and characterization of air barrier and moisture management systems

While building airtightness is a key concern in Nearly Zero-Energy Buildings in most European climates, there exists already a wide range of commercially-available products specifically designed to minimise leakage in building envelopes.
 
The objective of this webinar was to give information on the performance and properties of these products based on research including laboratory and field tests. The speakers provided information on standards already published and under development on this subject.
