The idea of cooling a building overnight probably originated at the same time as heating a house. As early as the Middle Ages in southern Europe and the Middle East, wooden shutters with slits or small holes were mounted in front of the "windows" to prevent the building from heating up too much.
While in our latitudes, with the temperatures prevailing here, this topic was not a top priority for a long time, in modern architecture, air conditioning and air exchange are attributed an important role.
Without the complex use of air conditioning units, it is possible to create a balanced climate through the temperature difference and the resulting air currents alone.
The night ventilation is an energy-saving passive room cooling.
The sheets provided for shading and air exchange offer additional protection against rain, hail, wind and also pests. The air diffusers, design and free cross-sections can be freely selected according to taste and use.
In summer, it often gets unbearably hot in offices, schools and other buildings. In addition, people, equipment and lighting constantly give off heat.
Large modern glass fronts further intensify this effect. To counteract this, the work area must be cooled.
Controlled natural ventilation uses the natural pressure differences between the inside of the building and the outside for air exchange.
Such a pressure gradient can be quickly achieved by opening windows and shading them with perforated sheeting. Additional fans or a large amount of energy are not necessary.
The shading can be in the form of movable blinds that automatically adjust themselves according to the sun, a classic window shutter, or by means of a parallel vent window that additionally ensures the security of a building.
In addition to sustainability and energy efficiency, this offers a natural and environmentally friendly source of cooling.
A ventilated façade, such as the façade of the Euronews building produced by DF-Perforated Sheets, offers higher energy efficiency than an unclad building.
The perforated sheet façade can provide effective protection against heat when there is a lot of sunlight. At the same time, strong heat transfer between the façade and masonry is reduced.
The perforated sheet structure and air circulation can dissipate heat build-up and reduce the temperature of the building exterior.
