We examine everyday practices in terms of their social structuring, cultural significance, and spatial dimension, as well as their internal logic, habitualization, and change. Everyday actions almost always involve a reference to the materiality of the world—infrastructures, artifacts, geographical conditions—as well as energy and resource consumption. Our research analyzes how these relationships arise, intensify, stabilize, or break down from various perspectives. Sustainability is addressed in its ecological and social dimensions, which are regularly pitted against each other in socio-political debates. In our analyses of socio-ecological transformation processes, we consider questions of social power relations and social inequality.

The topics in which lifestyle and sustainability are empirically investigated at the professorship include

• Spatial mobility and transportation
• Everyday practices and lifestyle
• Living and working
• Nutrition
• Design and changes in the built city
• Ideas about possible futures
• as a cross-cutting issue: social inequality.
