Home swapping as instrument for more housing sufficiency!

The current ecological challenges with an urgent necessity to reduce consumption of energy and resources call for a reconsideration of many aspects of current (western) lifestyles. Since housing is one major source of energy and resource consumption, the development of a sustainable housing provision is of upmost importance. Unfortunately, the public debate is constricted to efficiency and consistency measures, based on technical improvements, which do not question norms and values leading to necessary lifestyle changes. Such a one-sided approach will fall short for various reasons – the most important being the ever-increasing per capita housing space that cancels out efficiency gains. Instead, discussions on an environmentally sound housing provision should consider the concept of sufficiency, leading to a reduction of the physical building stock due to a decrease in per capita consumption. Despite acknowledging the necessity of a reduced per capita living space, the academic debate remains quite limited without offering appropriate systematic strategies. Thus, this paper takes up the instrument of home swapping to discuss its holistic value, adding to the debate on sufficiency strategies in the field of housing. It is shown that home swapping has enormous potential to reduce per capita housing space by better allocating living space.
