Zugluft

Zugluft, a German word, literally translates to "draft" or "air current." It refers to an unintentional flow of air through a space, often caused by gaps or openings in a building's envelope. This can occur around windows, doors, electrical outlets, or where different building materials meet.

The presence of Zugluft is typically felt as a noticeable movement of air that can create a sensation of coldness, even if the overall room temperature is comfortable. It is a common concern in residential and commercial buildings, as it can lead to discomfort for occupants and contribute to energy loss.

From an energy efficiency perspective, Zugluft represents a pathway for conditioned air to escape a building and for unconditioned air to enter. This necessitates the heating or cooling system to work harder to maintain the desired indoor temperature, resulting in increased energy consumption and higher utility bills.

Addressing Zugluft involves identifying and sealing air leaks. Common methods include weatherstripping around doors and windows, caulking gaps in walls and around fixtures, and using foam sealant for larger openings. Understanding the sources of Zugluft is crucial for effective mitigation.
