glemm21

Wolfgang Rieder and his company are pursuing the goal of becoming climate-positive by 2030 by gradually replacing cement in the concrete matrix and implementing various sustainable approaches. This concept is being trialled in practice at the new headquarters in Maishofen. Rieder emphasises that the aim is to achieve CO2 neutrality by 2025 by focusing on innovative material combinations, digitalisation, waste reduction and extending the service life of products.

One example of this sustainable transformation is the new glemm21 headquarters, which was created by revitalising a disused bus garage rather than building a new one. Numerous materials and components such as steel beams, floor coverings and furniture were reused to save grey energy and reduce CO2 emissions.

The campus was designed to offer modern, flexible working environments while also incorporating green spaces and an integrated e-mobility concept. The building's façade is made of CO2-reduced glass fibre concrete panels, with 50% of the cement replaced by local pozzolans, resulting in a 30% reduction in CO2.

The existing building and numerous other components were reused under the motto ‘Reuse and Recycle’. These include an I-beam from 1958, 150 tonnes of recycled steel beams, furniture and even a dismantled Swiss stone pine wall cladding, which contributes to the modern, creative working atmosphere. Existing surfaces, such as old tiles from the car wash, have been retained and create an exciting contrast in combination with new materials. By renovating the existing building, the client saved around 1000 tonnes of CO2 compared to a new building and created an exemplary example of resource-efficient, circular construction. The transformation process was accompanied by a specialised engineering firm for energy-efficient construction.
