VoltAir - energy self-sufficient louvre window

Controlled natural ventilation minimizes the CO2 content in rooms with the help of a window and ensures good and healthy indoor air quality. On the other hand, valuable heat escapes through a window and enormously increases energy consumption and heating costs. It represents a weak point, so to speak, in the energetically sealed building shell. Louvre windows from EuroLam enable this balancing act between optimal ventilation of rooms without excessive cooling. With our energy self-sufficient louvre windows, with an integrated photovoltaic panel in the glazing, there is automatic, controlled, electrically operated natural ventilation without an additional power connection or the costly laying of cables in the building.

The energy self-sufficient louvre window works without an additional power connection. The energy is supplied by a photovoltaic panel integrated into the glazing. A control that is also integrated regulates the opening and closing of the window. In the basic version of the control, the times for ventilation are preset. The times were determined by EuroLam as part of a research project and are designed for optimal ventilation with minimal cooling of the room. Another form of control is equipped with monitoring of the CO2 content and temperature monitoring of the room air. This means that the limit value of 900ppm CO2 specified in DIN EN 15251 can be met even more precisely.
