The facade consists of etched glass shingles with several functions: they lend the building’s main body lightness with their transparency, insulate against cold and heat and form an essential part of the lighting arrangement for the building. The incoming light is refracted for the first time on the facade before entering the interior.

The facade was designed as a self-supporting construction, completely independent from the actual building. Steel framework elements make up the construction which supports the glass shingles on the outside as well as the glasswork on the inside of the structure. In this way it covers the completely free-standing concrete building like a double casing. Between the outer and inner glasswork there is a 90-centimetre wide light pit that makes it possible to direct daylight to the first subterranean level. This gap is equipped with cleaning lifts used for the servicing and maintenance of the building. In addition, it accommodates the lighting installation which illuminates the Kunsthaus during the night.  [ Kunsthaus Bregenz official website ]

The Kunsthaus Bregenz was conceived as a daylight museum. The facade made of glass shingles serves as a skin to diffuse daylight which first passes through rows of windows and then through the light ceilings in the halls.

Although the light has been refracted three times (glass facade, insulating glasswork, illuminated ceilings), it illuminates the halls differently depending on the time of day or year. In this way, a natural lighting atmosphere is created although the building has no visible windows. Over the hanging light ceiling, specially developed pendulum lamps, controlled by an exterior light sensor on the Kunsthaus roof, have been installed that complement the daylight. Every lamp can be controlled separately or as a group and can be infinitely dimmed (light management system Luxmate professional).

 The pendulum lamps hang in pairs at a 90° angle to one another and are equipped with 58 Watt fluorescent lamps and diffusion attachments. [ Kunsthaus Bregenz official website ]
