glemm21

Building owner Wolfgang Rieder focuses on material innovation, digitalisation, waste reduction and extended service life - the aim is to offset more CO₂ than is produced. One model for this is the glemm21 headquarters, a building that repurposes an old bus garage instead of building a new one. This saves the company grey energy and does not seal any additional areas.

The ‘reuse and recycle’ concept also characterises the interior: Old steel beams, floor coverings and furniture were reused. Historic building elements were retained and modern accents added. Overall, the conversion project saved around 1000 tonnes of CO₂ and demonstrates resource-efficient construction.

The headquarters offers modern work zones and green spaces as well as an e-mobility concept. Sustainable materials such as CO₂-reduced glass fibre concrete panels and regionally produced timber elements extend the life cycle of the building. A new hybrid hall made of wood and concrete increases production capacity, utilises zenith light for optimal working conditions and ensures better indoor air thanks to air humidification.
