13 January 2017, Webinar - On the quest for indices defining Indoor Air Quality. What is a reasonable approach?

Over the years, different approaches and indices have been used to define indoor air quality. The most frequently used, recognised by the public, and equated with indoor air quality are, of course, ventilation rate and concentration of carbon dioxide. Other approaches define the levels of dissatisfaction with acceptability of indoor air quality, as expressed by the building occupants. At some point in time, the total concentration of airborne volatile organic compounds was proposed, as well.

20 November 2014, Webinar - Status and trends in competent tester schemes in Denmark, Ireland and Sweden

Over the past few years, there has been an increasing number of airtightness tests performed in Europe either for specific high-performance buildings programmes or for a wide range of buildings in regulatory contexts. This has led to the development of competent tester schemes to contain potential legal and competition issues.

The objective of this webinar was to give information on the status and trends in airtightness testing in Denmark, Ireland, and Sweden including the details and feedback on competent tester schemes.

25 April 2018, Webinar – Ventilative cooling and summer comfort: Freevent project in France

Ventilative cooling reduces overheating, improves summer comfort and decreases cooling loads. It is therefore one of the most efficient ways to improve summer comfort. Conditions on site, thermal inertia, solar control and other constraints have an impact on the choice of the system and its design. The overall performance is linked to good sizing, design, correct usage of thermal storage, and last but not least a correct control, commissioning and maintenance.

17 December 2015, Webinar – Ventilative cooling potential and compliance in Energy Performance regulations — Status and perspectives in Belgium, Estonia, Greece

Ventilative cooling—i.e., the use of natural or mechanical ventilation strategies to cool indoor spaces—can be very effective to reduce the cooling energy demand in buildings in summer or mid-season conditions. This webinar was part of a broader series focusing on ventilative cooling in energy performance, within the context of compliance with building regulations in several countries.

8 December 2015, Webinar – Assessing ventilative cooling potential in Energy Performance regulations. Status and perspectives in Austria, Denmark, France

Ventilative cooling –i.e., the use of natural or mechanical ventilation strategies to cool indoor spaces– can be very effective to reduce the cooling energy demand in buildings in summer or mid-season conditions. The principal objective of this webinar series was to give the status, needs, and perspectives on developments to consider ventilative cooling in energy performance assessment methods in several countries. This first webinar will focus on the developments in Austria, Denmark and France.

1 July 2013, Webinar – Building and Ductwork Airtightness: Legislative Drivers, New Concerns and New Approaches

The implementation of the EPBD recast puts increasing pressure on the market to achieve better building and ductwork airtightness: for most European climates and countries, good airtightness levels are necessary to achieve nearly zero-energy buildings. The webinar aimed to inform about legislative drivers that have brought to light new concerns and stimulated new initiatives. Recent trends in European regulations as well as field studies supporting the development of competent testing schemes were discussed.

4 June 2013, Webinar - Building Airtightness Solutions: Recent Research and Characterisation of Sealants and Tapes

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 minimize 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 also provided information on standards already published and under development on this subject.

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.
