Further roof solutions for daylight, ventilation and smoke and heat exhaust. In addition to smoke extraction hoods, flat roofs can incorporate rooflights for daylight, ventilation, roof access or smoke and heat exhaust. Our article on configuring and comparing flat-roof domes online helps with product selection and technical assessment. Natural ventilation of underground car parks uses openings or ventilation shafts for air exchange. Wind pressure, thermal buoyancy and pressure differences move the air, so a continuously running fan is not required to generate airflow. However, this solution is not automatically suitable for every car park. Size, use, traffic volume, geometry and state building regulations determine the requirements. The openings must also be sufficiently large, appropriately distributed and...

Night cooling, also known as night cooling, is an innovative method of air conditioning for buildings, schools, kindergartens and homes that is used particularly in hot summer months. It is an environmentally friendly and cost-efficient solution that is primarily used in modern buildings such as data centers, schools, kindergartens and offices.
How night cooling works
Night cooling uses the cooler temperatures of the night to cool the interior of buildings. This natural method of building air conditioning reduces the need for artificial air conditioning, resulting in significant energy savings.
