Breathing Facades: Facade Technology toward Decentralised, Natural Ventilation
The German firm Josef Gartner Ltd. has been developing facades with different versions of double-shell systems since the 1980s – and these are now increasingly being employed for decentralised facade ventilation in the Anglo-Saxon lands. In German-speaking countries, in contrast, prefabricated facade modules, either with or without deflector skin – including ventilated cavity – as wind protection, have come out ahead.
The firm’s newest development is the operable closed-cavity facade (CCF). More and more, maintenance costs play a decisive role in life-cycle costs or building envelopes. This is one reason that, particularly in countries with high income levels, the first low-maintenance double-shell facades – such as the elaborate CCF facades – are being implemented.
