About the team
Our interdisciplinary project team from the Biberach University of Applied Sciences consists of energy and civil engineers, project managers and architects. Students work on the project with the support of professors. But also, the various institutes of the university contribute to the progress of the project with their profound expertise, innovative approaches and practical experience.
‘The SDE21 gives us students the chance to gather specialized expertise in the field of energy-efficient construction and hone both our practical and social skills.’

The competition entry of Team X4S pursues the following project goals:
Resilience and robustness
The project contribution follows an efficiency strategy that is characterised by social, economic and ecological sustainability. The compact building is limited by an energy efficient and multifunctional building envelope.
Active and passive solar energy is to be used on the shell. The high quality new building will upgrade the existing building and enable its renovation while retaining its existing use. Gentrification is to be avoided and affordable rents with a minimal CO₂ footprint achieved. In order to maintain the rent level, an appropriate use of resources is important.
innovative timber construction
Innovative timber construction offers considerable potential for existing buildings due to short construction times, low loads to be borne and the storage of CO₂ in the building structure. A specific technology is the use of hardwoods. When used correctly, hardwoods offer advantages for the load-bearing structure.
Besides, the increased use of hardwoods for construction purposes is an important perspective for sustainable timber construction in view of climate change and the use of local resources. The high degree of prefabrication of wood modules specially adapted to the situation also reduces the construction time on site.
To meet the increasing importance of domestic hardwoods in the industry due to climate change, beech is used in some cases. With its low dead weight and ability to store CO₂, wood is basically an excellent building material.
A central element of the concept at a technical level is the reduction of the energy and resource consumption. On a social level, the aim is to strengthen and enhance the current social structure and to implement the concepts at minimum cost in order to avoid gentrification. This increase in efficiency will be achieved through coordinated measures, from the resource-saving use of materials to a highly optimised building envelope and grid-compatible operation.
‘The SDE21 offers the university an opportunity to demonstrate its expertise as it competes with 18 other colleges and universities. Our concept clearly focuses on sustainability at every level. That includes architecture, urban integration and intelligent, regenerative energy production.’
