Housing has a vast impact on our environment and society. This impact has categories with certain limits. Some of these limitations are given by the planet. They range from resource shortages to climate change. The boundaries in the social field result from the society that we, as citizens of the world, want to have. It includes aspects such as social justice. Strategies can help us to stay within these boundaries. Sufficiency is a promising strategy that focuses on achieving sustainability goals through changes in human behavior. While it has yet to gain much attention concerning residential buildings, some general concepts and criteria have demonstrated their worth in theory. So far, no evaluation system assesses all impacts of housing with consideration of the limitations. An evaluation system based on the Doughnut Economics model of Kate Raworth meets this requirement. This system allows analyzing the effects of sufficiency aspects on housing in a case study. Thereby one learns about the sufficiency aspects of housing.
The results additionally give the knowledge to improve the evaluation system. An examination of strengths, weaknesses, opportunities, and threats for the sufficiency aspects personal living space, energy demand, and low-tech gives an overview. These aspects are tested in a case study on a standard multi-family home which concerns the global warming potential, representing the global environmental impact, and affordability, representing social local factors. All aspects reduce the global warming potential. But none of the applied sufficiency aspects lowers the effect to a level compatible with the evaluation system's boundaries. Besides this, the aspects of personal living space and energy demand improve housing affordability by reduced costs. In general, sufficiency aspects affect housing's social and environmental impact, and the evaluation system helps to understand these effects. Other strategies must accompany sufficiency to reach more sustainability. Further research, application to real-world buildings, and the enhanced evaluation system guide us into strong sustainability in housing.
