Stoßlüften

Stoßlüften, or “shock ventilation,” refers to a method of rapidly ventilating indoor spaces to improve air quality and reduce humidity levels. This technique is particularly relevant in the context of energy-efficient buildings where airtightness is a priority.

Stoßlüften involves opening windows wide for a short period, typically 5 to 10 minutes, to allow a significant influx of fresh air into a room. This practice is essential in modern UK homes, especially those built to high energy-efficiency standards, as they often have limited natural ventilation to prevent heat loss.

Practical Examples

1. Energy-Efficient Homes: In newly built homes adhering to the UK’s Building Regulations, achieving a balance between energy efficiency and indoor air quality is crucial. Stoßlüften allows residents to quickly refresh the air without compromising the thermal envelope of the building, thereby maintaining energy efficiency.
2. Retrofit Projects: During the retrofit of older homes, where insulation might be improved, implementing Stoßlüften becomes vital. For instance, in a Victorian terrace house that has been retrofitted with modern insulation, regular Stoßlüften can help mitigate issues related to condensation and mould growth, ensuring a healthier living environment.
3. Case Study: A family living in a Passivhaus (a building standard aimed at ultra-low energy use) successfully uses Stoßlüften during the winter months. They open their windows for a few minutes each day, which helps maintain a comfortable indoor climate while keeping heating costs low. This case illustrates the practical application of Stoßlüften in energy-efficient homes, highlighting its role in balancing comfort and efficiency.

Understanding Stoßlüften is essential for homeowners and builders in the UK, particularly in the context of energy-efficient construction and retrofitting. By incorporating this practice into daily routines, residents can enhance their indoor air quality while preserving the energy performance of their homes.
