Ventilation

Importance of ventilation concepts

When buildings are used, ventilation and thus the exchange of "used" air is becoming increasingly important. This is because the used air in buildings in which people live or work has to be regularly replaced by fresh air.

Whereas in the past the natural exchange of air or window ventilation often led to this exchange, intelligent ventilation concepts are required in the course of energy-efficient building planning and the changed use of buildings. The building envelopes become denser and the individual functional layers in the exterior components are optimised to meet the building physics requirements. Thus, within the framework of ventilation concepts - supported by special ventilation systems - the required air exchange is regulated across all areas of use.
 

Importance of ventilation concepts


In the event of a fire in residential or non-residential buildings (e.g. commercial buildings, special buildings such as hospitals, nursing homes or schools), ventilation ducts must be fireproof so that no hot gases or smoke can enter other areas instead of the supply or exhaust air. A fire-resistant or non-flammable design prevents the spread and significantly reduces the fire hazards.
