Bauwerksdachkühlung

Bauwerksdachkühlung refers to a cooling system integrated into the roof structure of a building. Its primary function is to reduce the internal temperature of the building by actively removing heat from the roof area. This can be achieved through various methods, most commonly by circulating water or air through pipes or channels embedded within or on the roof. The cooled medium then absorbs heat from the roof surface or the space beneath it.

One prevalent type is active Bauwerksdachkühlung, which utilizes mechanical systems like pumps and fans to circulate a coolant. In contrast, passive systems rely on natural processes such as evaporation or radiative cooling. Evaporative cooling systems, for example, involve wetting the roof surface, and the subsequent evaporation of water draws heat away. Radiative cooling systems are designed to reflect solar radiation and emit thermal radiation into the atmosphere, thereby lowering the roof's temperature.

The benefits of Bauwerksdachkühlung include a reduction in a building's energy consumption for air conditioning, as less heat enters the interior. This leads to improved thermal comfort for occupants. Additionally, it can contribute to mitigating the urban heat island effect by lowering ambient temperatures in densely built areas. The implementation of Bauwerksdachkühlung can vary significantly depending on the building type, climate, and available resources.
