BGN ventilation calculator

Open the windows and ventilate - that is the easiest way to comply with the requirements of the SARS-CoV-2 occupational health and safety regulations when ventilating workrooms. How often and for how long depends on the room size and the number of guests in the room. 1,000 ppm is the maximum CO2 concentration in the room generated by human exhalation.

The BGN has developed a simple ventilation calculator and put it online, which anyone can use to determine how often rooms must be ventilated during corona times if no ventilation systems are available.

Can also be ordered in the media shop
