Research news - One in five persons in Germany suffers from a pollen allergy. During pollen season, the question of how to air rooms without triggering allergies constantly arises. A team at the Professorship of Ecoclimatology at the Technical University of Munich (TUM) systematically investigated pollen concentrations in office spaces and derived practical tips for airing rooms from the data. According to the 2013 issue of the German Federal Health Gazette, around 15 to 20 percent of the population in Germany suffers from hay fever. Because Europeans and North Americans spend over 90 percent of their time in closed rooms, pollen concentrations in buildings need to be taken into account. In addition to meteorological factors, the type and frequency of room ventilation was also taken into account in the study published in the specialist journal 'Indoor Air'. During their investigations, the authors at the Professorship of Ecoclimatology at TUM concentrated on birch pollen, as it triggers allergic reactions with particular frequency, as does grass pollen.
