The construction of buildings brings about a substantial ecological load: about 40% of energy consumption and about 25% of material moved by our economy is due to the construction of buildings. New construction technologies and new building components would allow us to reduce the ecological load of buildings to a fraction of its present value. However, the problem of making our building stock more sustainable is only to a minor extent a technical one. The required change of technologies can only be managed by simultaneously taking into account technical potentials and their social context. Social studies of technology, with their focus on the construction of technologies as an interactive effort of various actors and on the inseparability of the social and technical side of sociotechnical systems provide a perspective to better understand the processes involved in the construction and dissemination of sustainable buildings. A number of strategies to manage technical change towards sustainability will be discussed: better integration of various actors at the supply side, shift to a market for innovative and ecological building services, improvement of user-producer relationships and integration of consumers into the innovation process.
