Zumtobel illuminates first high-rise building with wood-hybrid construction
03.12.2012
In Vorarlberg, Austria, the first high-rise building with wood-hybrid construction – called LifeCycle Tower – is being built. A unique piece of architecture is being created based on a resource-conserving method of construction. The 8-storey high-rise building features a major innovation: no panels are fitted to the weight-bearing elements of the building. In this way, even the inside of the bare, unclad wooden structure can be experienced, which saves resources and is also a fire protection measure.

As a leading provider of trendsetting lighting solutions, Zumtobel has developed a customised lighting concept for the LifeCycle Tower that is based on the latest standards. The integral lighting concept allows to save energy on a sustainable basis while creating a high-quality ambience in the rooms. In addition to Zumtobel, the Vorarlberg-based architects' studio Hermann Kaufmann, the international engineering studio Arup as well as the Wiehag wood construction company and Graz University of Technology are involved in the international research project.

Daylight-based lighting management and lighting quality
In addition to state-of-the-art, perfectly glare-free office luminaires and energy-saving LED lighting for corridors, Zumtobel's Luxmate Litenet lighting managements system is used in the world's first high-rise building with wood-hybrid construction. Luxmate Litenet combines complex system features such as use of daylight, presence detectors, integration of emergency lighting, and predefined room profiles in one central unit that can be easily operated. An external daylight sensor continuously monitors incident daylight and accordingly adds only as much artificial lighting in each room as required in order to provide a perfect lighting solution. This saves unnecessary energy costs. The cost reduction concept is also assisted by presence detectors: the luminaires' switching times, which can be flexibly set, make sure that unnecessary lighting of individual rooms is prevented, thereby helping to save energy.
Also the level and slat position of the blinds are accurately set by Luxmate Litenet. In the process, recurring lighting and blinds situations can be configured as scenes and called up at the press of a key via the control units, if required.

Reliability in emergency cases
Light is extremely important in situations where people need guidance and safety: Nearly hundred emergency and escape sign luminaires of Zumtobel's Onlite product range – linked to the Luxmate Litenet lighting management system – are used in the high-rise building. They are supplied by an autonomous emergency power source and monitored. The complete state-of-the-art LED emergency lighting system is displayed and controlled via the lighting control program. This keeps the maintenance effort low. Moreover, system checks are run automatically for the most part and are also logged.

Perfect light for people, in harmony with the environment, seems to have been implemented perfectly in the world's first high-rise building with wood-hybrid construction.
