In the new laboratories, the scientists also want to work on innovative air ducts for special spaces, such as operating theaters. The new ducts should prevent, for example, that germs enter with the rising air in the operation area during surgery. In the Test Center, there is space for vehicles. As a result, the experts can also check the air quality in cars. These tests are necessary because there are a number of new composite materials in the vehicle models.
In what ways can it now be determined how good the indoor air is, or to what degree it has been consumed? "Until now, only a high concentration of CO2 could be an indicator of poor air quality. This value is measured by sensors, which report it to the ventilation system. We go one step further and investigate other parameters at the same time. In doing so, we use sensors to record the carbon dioxide, nitrogen oxide and ozone levels. We also rely on metal-oxide semiconductors that respond to food, drinks and human scents," describes Burdack-Freitag. On the basis of various measurement data, a ventilation control can respond more accurately than before, such as to stuffy air during meetings.
Which ventilation should be used in which building is one of the key issues during the planning phase of a new building. "In this process, it's important to keep in mind that air exchange rate and ventilation efficiency are two different parameters. The rate describes the air volume that flows into the room in one hour. If fresh air doesn't move through the room, but instead right back o
