Brussels, Krakow, 10 October 2016. In the course of its 2016 Eurovent Summit, the Eurovent association has released the first edition of its air curtain standard. The code of good practice titled Eurovent 16/1 defines the first testing efficiency calculation method for air curtains. The document fills a standardisation gap, which has characterised these products for a long time. It defines the Air Curtains’ categories, standard rating conditions, and testing methods, and it can serve as input of how to calculate the buildings’ energy saving by using Air Curtains.
