9 November 2011, Webinar – Achieving better envelope airtightness in practice-Recent Norwegian training and dissemination schemes

Following the recast of the energy performance of buildings directive published in May 2010, EU countries will have to implement regulations to increase the number of nearly zero-energy buildings (NZEB) in the next few years, and to generalize nearly zero energy targets in new buildings and major renovations. In most European countries, building and ductwork leaks have a significant impact on energy performance and indoor climate and therefore merit special attention in the context of this directive.


6 March 2018, Webinar – IAQ sensors for smart ventilation of buildings

AIVC defines smart ventilation as a process to continually adjust the ventilation system of a building in order to provide the desired Indoor Air Quality (IAQ) benefits while minimizing energy consumption, utility bills and other non-IAQ costs (thermal discomfort, noise, etc.). Smart ventilation responds to one or more of the following: building occupancy, outdoor conditions, electricity grid needs, operation of other building systems, direct sensing of contaminants.


26 March 2020, Webinar – Ventilative Cooling – design and examples

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. Ventilative cooling can be an energy efficient solution to address this cooling challenge in buildings.


30 January 2020, Webinar – Durability of building airtightness: Assessment through field measurements

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. However, rather limited expertise is available as regards the durability of building airtightness at mid- and long-term scales.


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.
