We received the information from CEN that the result of the vote among the CEN Technical Board (CEN-BT) on EN779-2012: Particulate air filters for general ventilation - Determination of the filtration performance was “disapproved”

Total 22 approvals were received so nearly whole Europe and only Italy (UNI) emitted a fundamental disagreement. For a lot of CEN-TC participants who worked for many years on this standard it was disappointed and frustrated to hear that only one country can block their voluntary work done so far.

We understood that it is now up to CEN-BT to decide what to do with the appeal from Italy and hopefully they will do it during the March meeting. We are convinced that CEN-BT will make a wise decision and that the revised EN779 will be soon the new standard.

This is to inform you that the REHVA Annual Conference will take place in Timisoara, Romania, April 19-20 2012. 

The REHVA Annual Conference is organized in cooperation with the Romanian Installation Engineers Association (AIIR) and the Romanian General Association for Refrigeration (AGFR) in Hotel Timisoara. It is situated in the cultural and historic centre of Timisoara overlooking the Opera Square.

Air filters are related to high consumption of energy by the fans in the ventilation systems. There is a potential saving by using the most efficient air filter, in terms of low pressure drop and efficiency according to European filter standards.

A duct system is the conveyer system of treated air from one location to defined destinations in buildings and it is important that all the air arrives at the destination point/outlet, this means leak tightness ducts.

Based on a top down calculation Eurovent concluded that for air filtration the energy saving potential is 3,150 GWh/year and for ducts 29,550 GWh/year so totally nearly 33,000 GWh/year.
