The OPENLY AIRBOX© is an innovative and controlled residential ventilation system that positions itself as a sustainable alternative to conventional solutions. Unlike Minergie ventilation, where air is often pumped into rooms through ducts or drawn in through window vents with exhaust vents in wet rooms, the OPENLY AIRBOX© responds directly to indoor air quality: As soon as the CO₂ level or humidity reaches a critical threshold, the Airbox opens automatically and provides fresh air. In the summer, the Airbox also plays a key role in nighttime cooling by dissipating excess heat, thereby optimally regulating the indoor climate.

OPENLY AIRBOXES© offer a flexible and effective ventilation solution that can be combined with any standard window. They are installed in the window reveal, which not only has aesthetic but also practical benefits: the airbox remains invisible from the outside, while at the same time increasing sound insulation and ensuring pinch protection by eliminating the need for open windows.

Another advantage is the uncomplicated handling: the windows can of course also be opened manually if desired. In this way, the comfort of a classic window is retained, while the benefits of automated ventilation are fully exploited.

Compared to traditional Minergie ventilation systems, the OPENLY AIRBOX© therefore offers a more resource-efficient and flexible solution that is impressive in terms of technology, comfort and design. Thanks to its intelligent placement in the reveal, the airbox blends harmoniously into the façade without detracting from its appearance.

In summary, the OPENLY AIRBOX© stands for visual clarity, efficient sound insulation, safety thanks to anti-trap protection and an optimum indoor climate at all times - and all without complex pipe systems.

Since February 2025, Openly Airboxes have been receiving Minergie P certification and are therefore eligible for cantonal subsidies in Switzerland and KfW 40 funding in Germany.

The OPENLY AIRBOX is just the hardware with a simple open/close logic.

The air boxes are controlled by CO2 and temperature sensors located in each room. These sensors are connected via the EnOcean wireless protocol and are installed by our technology partner CLEVERSON during commissioning. No electrical planning is required!

The algorithms of the underlying control system can be individually adapted to the building and its occupants.
