Ilmanvaihtokyky

Ilmanvaihtokyky refers to the ability of a building or a space to effectively exchange indoor air with outdoor air. This process is crucial for maintaining good indoor air quality and ensuring a healthy and comfortable living or working environment. Proper ilmanvaihtokyky helps to remove pollutants, excess moisture, and odors, while also supplying fresh oxygen.

There are two primary methods of achieving ilmanvaihtokyky: natural ventilation and mechanical ventilation. Natural ventilation relies on the natural movement of air, driven by pressure differences created by wind and temperature variations. This can be achieved through open windows, doors, and other openings in the building structure. Mechanical ventilation, on the other hand, uses fans and ductwork to actively move air in and out of the building. This system can provide more controlled and consistent air exchange, regardless of external weather conditions.

The effectiveness of ilmanvaihtokyky is influenced by several factors, including building design, airtightness, the presence and type of ventilation systems, and occupant behavior. Inadequate ilmanvaihtokyky can lead to a buildup of pollutants, potentially causing health problems such as headaches, fatigue, and respiratory issues, often referred to as "sick building syndrome." Therefore, ensuring sufficient and appropriate ilmanvaihtokyky is a fundamental aspect of building design and maintenance.
