The concept of putting a winter garden inside a glass exterior, covering the ellipse-formed office building is a essential component of the ''intelligent house.''
The winter garden itself provides an 'in-between room' thanks to the the free form of the building's central construction and the outer corner. It is used as an accessable area to enjoy and offers a clear advantage over conventional facades.
The ship's-hull-formed outline provides distance between the bordering buildings, so that a optimal view and light intensity can be achieved for all office rooms.
The transparent exterior therefore acutely fulfills its purpose by sealing off the offices from the heavily trafficed Klingelhöferstrasse. Protecting against pollutants and vehicle exhausts, the glass facade enables the office windows to be able to remain open.
At the same time, the winter garden fulfills the function of climate control, protecting against the warmth in the summer and retaining the warmth in the winter. This is made possible thanks to a natural ventilation of the winter garden through side openings in which fresh air and humidity can be upwardly released through the hand-accesible windows.
Access warmth is prevented by thermal ventilators in the summer months. The rising warm air in the upper area is funneled outside by the ventilation elements. In addition, the inner facade is protected by a outer attached sunscreen, that provides additional cooling during the summer months.
During the winter months, the sunlight heats up the airspace and forms a warm air cushion around the building, just like a greenhouse.
