Requirement:
DIN EN 15251: 2012 / DIN EN 16798-3
Outside air volume flow: between 20 and 36 m³ / h per person.
Average CO2 concentration: 1000 ppm
In this case, the iV-Office is designed with 25 m³ / h per device, resulting in an outside air volume flow of 100 m³ / h with 4 devices in the room (two pairs of devices).
This corresponds to 5 m³ / h per person with a group of 20 people.
