Belüftungsfunktion

Belüftungsfunktion refers to the process of air exchange within a space, typically a building. Its primary purpose is to ensure a healthy indoor environment by removing stale air and introducing fresh outdoor air. This exchange is crucial for diluting and removing indoor pollutants such as carbon dioxide, volatile organic compounds (VOCs), moisture, and odors.

There are several methods to achieve belüftungsfunktion. Natural ventilation relies on pressure differences caused by wind and temperature variations to drive air through openings like windows and doors. Mechanical ventilation systems, on the other hand, use fans to actively supply and exhaust air. Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) are advanced mechanical systems that pre-condition incoming fresh air using the thermal energy of the outgoing stale air, thus saving energy.

Effective belüftungsfunktion is vital for occupant comfort and health, preventing issues like condensation, mold growth, and the build-up of unhealthy air concentrations. The design and implementation of ventilation systems consider factors such as building size, occupancy levels, and the specific intended use of the space to ensure adequate air change rates and maintain optimal indoor air quality. Regulations and standards often dictate minimum ventilation requirements for different building types.
