Good design is ultimately a combination of understanding what the market needs, what technology can deliver, and how the underlying physics affect the performance. In order to tackle the challenges ahead, we rely on in house specialists in different fields, in close collaboration with top Universities and Research institutes that provide state-of-the-art information. The main difference with traditional companies is that we are not held back by any existing products or market positions. The Fassada H60 hybrid concept was studied profoundly in different fields (e.g. dynamic mechanics, watertightness, pressure equalization…), and the combination of experience, academic research and intensive laboratory and field testing provide the basis for this success.
