läpivetävyys
Läpivetävyys is a Finnish term that describes the phenomenon of air or wind passing through an enclosed space. It refers to the ability of air to circulate or move through a building, room, or other enclosed area. This can occur through intentional openings like windows and doors, or unintentionally through leaks and cracks in the building's structure. The concept is important in building science and ventilation, as it directly impacts indoor air quality, energy efficiency, and thermal comfort.
High läpivetävyys can lead to drafts and heat loss, making a building uncomfortable and increasing heating
