Wiener Linien is building a new campus to train its apprentices, in which sustainability and a low carbon footprint play a big role. Located in the main workshop in Vienna's Simmering district, Wiener Linien’s Apprentice Workshop 2.0 will be built with sustainable materials and using an energy-efficient construction method. The basement floor will be made from recycled concrete, the ground and first floors will be a solid wood construction. The structure will be heated with geothermal energy.

The building’s roof will be greened and a photovoltaics system will provide energy. Machine halls and state-of-the-art workshops will be located on the new building’s ground floor. Above it, modern training, laboratory and lecture rooms will adorn the first floor. Open common rooms are supposed to promote exchange of ideas and knowledge.

More than 1,100 m³ of glued wood products from the Hermagor, Sachsenburg and Stall locations were used. NORITEC Holzindustrie GmbH, located at the site of the HASSLACHER Group in Stall im Mölltal, supplied 2,200 m² of HASSLACHER ribbed panels, consisting of 233 m³ of cross laminated timber and 193 m³ of glued laminated timber. Using the so-called screw-clamp method, these were used to make 80 elements. The Sachsenburg and Hermagor sites provided 365 m³ of glued laminated timber, some of it post-processed composite elements. Thanks to the use of wood, this building sequesters 830 t of CO_2.
