The 1st Expert meeting of the IEA EBC Annex 62- Ventilative Cooling will be held from Wednesday April 23 to Thursday April 24, 2014 in Lausanne, Switzerland.
IEA EBC Annex 62 has now entered the working phase with as first focus the preparation of the first Annex deliverable, the State of the Art report. At the 1st expert meeting, the first draft will be discussed with the intention to have the final version ready before the second expert meeting in September 2014. In parallel, research work on the subtasks according to the work plan will be initiated.
AIVC aims to play a central role in the ventilation and infiltration community with respect to the dissemination of information, either with its conferences or workshops, or with the material available on its website. The annual conferences continue to be greatly appreciated: 96 % of a sample of 76 conference attendees rated the 34th conference as excellent or satisfactory, 91% would recommend it to others. As you will see in this newsletter, we are working to uphold this quality for our future events.
There is a trend to perform more ventilation and air infiltration measurements in buildings, either to strengthen commissioning procedures or to learn from field data. This trend is stronger in nearly zero-energy buildings projects or programmes given the significant share of ventilation and infiltration losses on total building energy use.
The design of fans has evolved to meet the ever-increasing demands for higher efficiency machines, combined with the requirements for lower noise and high availability. In addition many fans are now being used in safety related applications, such as smoke control in buildings and underground spaces in the event of a fire. Variable speed is now more common, leading to some additional design problems and many existing users are revisiting their plant looking at ways to upgrade the fans.

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 venticool platform was inaugurated in September 2012 in response to the needs felt to increase awareness regarding ventilative cooling and to foster exchanges on this topic both for practitioners and researchers. 15 months later, its relevance is clearly confirmed:
