A walkable façade corridor is created between the levels, which functions as a solar air collector . The short-wave solar radiation is absorbed in the space between them and heats the air. On cooler days, employees can manually open the inner glass level to channel the pre-heated fresh air into the building.
When the outside temperature is high, the outer glass layer is opened, allowing the heated air to escape. The inner, thermally insulated facade remains closed to protect the interior from overheating. The installed sun protection glass allows plenty of daylight to enter, but reflects infrared radiation and thus prevents unwanted heat generation. 

It all began in 2010, when an innovative building's shell was sought for the Dutch branch in Nijverdal. This should reflect the corporate values of openness and transparency to the outside world, establish communicative connections between indoor and outdoor spaces, and take into account the manufacturer's product range. On this basis, façade planners Marcel Bilow and Dr. Thiemo Ebbert from imagine envelope developed the CO2mfort façade together with Thomas Auer  from Transsolar, Professor of Building Technology and Climate-Friendly Construction at the Technical University of Munich, in cooperation with the TU Delft  . It is based on a resource-saving energy concept with minimal use of technology (low-tech instead of high-tech) and places particular emphasis on the active participation and influence of the employees. 

The most recent practical example is the showroom of the Allgäu-based building element dealer Linara in Kaufbeuren, which opened in 2024, a 100 percent subsidiary of the Solarlux Group. Here, too, the CO2mfort facade  ensures natural air conditioning of the offices with fresh air supply. The double-skin façade was designed in the area of the office landscape, allowing individual and manual control system of the indoor climate. Architect Peter Kuczia on the "Depending on the weather, employees can unfold the bi-foldings inside and let the pre-heated fresh air flow into their workspaces." This is especially advantageous on colder days. In hot weather, only the outer slide-and-turn elements are fully opened. This prevents heat build-up."

How can environmentally friendly living be combined with a high standard of living? Answers to this question are provided by the new Solarlux concept house in the Salzkammergut region of Upper Austria. The building, which was constructed almost entirely in wood, was designed as an atmospheric place that makes modern and sustainable architecture tangible with all the senses. The architect achieved this, among other things, through careful integration into the unique mountain landscape, generous, movable glass facades that create seamless transitions between indoors and outdoors, a loggia as a climate buffer, and a building technology that consistently relies on renewable energy sources. 

The 3 m deep loggia serves as a climate buffer, with the indoor climate individually controlled by the opening and closing of the cero sliding window on the inside and Proline T sliding-turn elements on the outside.

In Vienna's 5th district of Margareten, feld72 Architekten ZT GmbH closed a gap that had existed for decades. The design eye-catcher is the delicately structured glass front facing Straussgasse, which encloses and at the same time emphasizes an old building. Visual depth is created by the glass, one-meter-wide buffer zone in residential floors three to five. These are designed as convertible Wintergardens protected from noise and weather, which can be flexibly opened and transformed into airy loggias using floor-to-ceiling sliding elements of the Solarlux Proline S Mega system.
