Natural ventilation: Harnessing wind and heat to create a good internal climate

Cost-effective and energy-efficient climate control

Our natural ventilation systems harness wind and heat to create a comfortable and healthy internal environment, with optimal temperature and humidity levels, and good air quality.

Our natural ventilation schemes consist of automatically opening and closing windows and rooflights, and can range from a simple open/close switch to a fully integrated energy management system with carbon dioxide and temperature measuring, weather sensors and interfaces with building management systems.

These systems can provide a highly energy efficient solution that requires a small initial investment to maintain a good internal climate with extremely low running and maintenance costs.
