3G multifunctional windows for Københavns Energi
The system consists of automatic ventilation windows in the front of the building as well as in the air shafts on the roof. The ventilation windows are so-called 3G multifunctional windows, which consist of a single layer of glass on the outside, where the lower part of the window can be opened, and of double window pane on the inside, where the upper part of the window can be opened.
Technical Specifications
Fresh air is let in through the low-set exterior window frame, ascends in the air space due to thermal buoyancy and is let into the offices through the high-set interior window frame. When the sun is shining the exterior air is preheated in the air space, which reduces draft. The fresh air is mixed with the existing air in the offices and sucked out through the chimneys in the ceiling, which primarily works due to the simple effect in chimneys (thermal buoyancy). The open and closing mechanism of the individual windows is done by aid of engines that are controlled by a thermostat/CO2 meter placed centrally in the rooms or by manual operation.
Between the panes are integrated window blinds that limit glare and reduce superheating of the rooms.
The natural ventilation principle has replaced the traditional mechanical ventilation system with piping hid under the ceiling and thus allows for the possibility of a 3.5 metre floor-to-ceiling height in the rooms. All windows are floor-to ceiling windows, which allow for the daylight to penetrate far into the rooms, thus reducing the need for artificial lighting.
