Webinars

The Air Infiltration and Ventilation Centre (AIVC) in collaboration with IEA EBC Annex 86 organized a spring workshop consisting of a series of four webinars on:

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.
 

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. You will learn about legislative drivers that have brought to light new concerns and stimulated new initiatives. We will discuss recent trends in European regulations as well as field studies supporting the development of competent testing schemes. 
 

AGENDA

PROGRAMME

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.

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.

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.

Building airtightness is a critical factor for Nearly Zero-Energy Buildings and represents a key challenge for the building sector.

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.

Presentations & Speakers:

There are several initiatives to collect building airtightness data from field measurements whose number increases rapidly with the trend towards low-energy buildings. The objective of this webinar was to give an overview of the needs identified in several countries and reasons behind the development of air leakage databases. This webinar was organised within an AIVC-TightVent project whose aim is to facilitate the development of air leakage databases.
