BGN-Lüftungs-Rechner und Timer Gute Luft ist eine der Grundlagen für Gesundheit, Wohlbefinden, Leistungsfähigkeit und für gutes Arbeiten. Personen in Räumen verändern die Innenraumluftqualität, da die CO2-Konzentration in der Luft durch die Ausatmung der Personen ansteigt. Manche Viren, wie z.B. Coronaviren, verteilen sich mit den ausgeatmeten Aerosolen in der Raumluft. Das Risiko einer Infektion kann durch richtiges Lüften gesenkt werden. Doch wie soll gelüftet werden? Die BGN-Lüftungs-App unterstützt Sie, den optimalen Zeitpunkt zum Stoßlüften für jede Raumsituation zu ermitteln. Dabei kann auch die Unterstützung durch eine technische Lüftung oder Raumluftreiniger mit berücksichtigt werden. Die App bietet eine Hilfestellung zum richtigen Lüften von Gaststätten, Büros, Besprechungsräumen und Kleinbetrieben. Zur Erinnerung kann ein Timer gesetzt werden.
