The Illwerke Zentrum building in Montafon by CREE

Montafon

Illwerke Zentrum

Representing a huge step forward for timber-hybrid construction in Europe, CREE’s first external customer order showcases its versatility and aesthetic possibilities against an idyllic backdrop in Vorarlberg, Austria.

This building breaks the mold: rather than towering over its lakeside surroundings, the hydropower center commands yet complements the landscape with its imposing length of 120 m. Each 2,000 m2 floor level went up and was enclosed in an impressive 7 days.

Complete with a works restaurant and visitor center, this project demonstrates the versatility of interior spaces in a CREE building. The IZM also represents a milestone in resource-efficient, sustainable construction: it is the first green building of its size in Vorarlberg and one of the largest office buildings in the world to use timber-hybrid construction. A bold and substantial step forward for CREE and Illwerke AG.

“In a modern office building, the issues of energy-efficient operation and cost-optimized maintenance are omnipresent. The optimal materialization of the surfaces, as well as the open structure of the workplaces, reduced the cleaning and maintenance costs per m2 by one third compared to our conventional office buildings. The use of a state-of-the-art building control system, which regulates the entire technical building equipment, such as heating, air conditioning, LED lighting technology, as well as the execution of the building envelopes in passive house quality, could reduce the energy consumption per m2 usable area to one tenth of the consumption of the original IZM office building from 1950. The IZM excels not only because of its energy figures, but also because of the feel-good factor that wood as a raw material brings to the whole building.”
