23 May 2019, Webinar – New Perspectives on Kitchen Ventilation

Cooking is a major source of indoor contaminants, including moisture, odors and particles. Proper venting of cooking activities is an essential part of providing acceptable indoor air quality in homes. This webinar will discuss kitchen venting, including measurements of contaminants that are emitted from cooking, discussions of kitchen exhaust ventilation system performance and guidance on best practices for kitchen ventilation.


12 January 2016, Webinar - Building airtightness and initiatives to improve the quality of the works

The QUALICHeCK-TightVent webinar: "Building airtightness and initiatives to improve the quality of the works" was held on Tuesday 12 January, 10:00-11:30 (Brussels time). The objective of this webinar was to give background information on selected initiatives to improve the quality of the works with respect to building airtightness.

The programme included 4 presentations of 20 minutes as follows:


27 April 2015, Webinar- Compliant Energy Performance of Buildings Certificates and better quality of the works — ground status, initiatives and perspectives

The Energy Performance of Buildings Directive recast gives ambitious goals for the building sector to reduce energy use as well as greenhouse gas emissions. It requires member states to engage in the generalization of Nearly Zero-Energy Buildings and to set up the necessary actions to support the mandatory availability of Energy Performance Certificates (EPC), both for new and existing buildings.

The objectives of this webinar were:


26 November 2012, Webinar - Demand-Controlled Ventilation in the European context Approaches in 4 countries and at EU level

Because ventilation represents a very substantial part of the space conditioning energy needs, there is a growing interest in European member states for Demand-Controlled Ventilation (DCV), i.e., for strategies and systems to control the amount of air provided indoors depending on the actual needs.

The objective of this webinar was to give an overview of the approaches developed in 4 European countries to consider these systems consistently with European standards, in particular, in an energy performance regulation context. 


20 November 2020, Webinar – COVID-19 Ventilation related guidance by ASHRAE and REHVA

Ventilation is recognized as a major element in strategies for minimizing the risk of COVID infection. REHVA and ASHRAE have developed guidelines taking existing evidence of long-range aerosol based transmission into account including the importance of ventilation.

This webinar presented the guidelines by REHVA and ASHRAE and also had a closer look to the similarities and differences in both guidelines.


30 November 2020, Webinar – Better Quantifying and Locating Building Leakages

Air infiltration in buildings has multiple consequences on energy use and indoor environmental quality which depend on the location and distribution of leakages. Among others, pollutant infiltration and air draft are highly affected by leakage distribution. In current practice, leakage detection is frequently performed together with an airtightness test. Leakage detection methods allow to identify the locations of the leakages, but in most cases do not allow to quantify the amount of leakage corresponding to each identified leakage.
