Nordic Ventilation Forum online was arranged for the third time. The webinar is part of a Nordic project for co-operation in the area of ventilation. It was initiated in 2020 by Nordic Building authorities in charge of ventilation regulation. The aim is to improve the information exchange between Nordic countries for better indoor environment and performance of ventilation, as well as develop background information for future development of ventilation, to maintain the leading role of Nordic indoor air quality and ventilation technology. The webinar is intended for all professionals who are interested in future development of ventilation technology.
