Collaborative Housing: A tool for social integration and increased sustainability
- 2022

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- All over the world there is a shortage of adequate, affordable housing that enables social integration and sustainability. Many individuals and households have access to housing but live in different kinds of involuntary isolation with respect to age, gender, income, culture and ethnic background. There is a lack of housing forms that can contribute to solving these societal challenges through different forms of tenure such as rental and housing cooperative. In Sweden, there is an urgent need to solve societal challenges and increase housing provision due to unwanted isolation, segregation and a housing backlogof more than 600,000 units. The production of new housing offers an opportunity for innovative housing solutions and a more connected society.There is an increasing interest in learning from recent experience of collaborative housing as a tool for social integration and increased sustainability. Collaborative housing in Europe seems to reappear during economic, social, cultural or ecological crises. This report is based on the research project Sustainable living in community: a step towards integration and reduced climate impact conducted by the authors. Collaborative housing projects in Sweden have been studied using systematic literature review, space syntax analysis, observations, questionnaire surveys, online diary, interviews with residents andprofessionals. In addition, recent examples of collaborative housing in Denmark and the Netherlands have been studied. A concluding workshop with different stakeholders in order to receive feedback to the preliminary findings has been conducted.This Building Issue highlights the concept of collaborative housing, as a housing form where residents collaborate within different stages of the project – from design to daily self-management of the building, agree on a common purpose and have social interaction among themselves. Collaborative housing can contribute to addressing several aspects related to social sustainability and social integration. Common spaces in a building can be designed to favour social integration of people with different backgrounds, ages and living conditions. Collaborative housing can embrace different forms of tenure and collaborationwith external actors and enables residents to exert their individual and collectiveeffort to make decisions concerning their living environments.The aim of this study is to contribute with practical knowledge regarding collaborative housing as a system and as a process to achieve adequate and affordable housing as well as for building bridges between people with different backgrounds and living conditions. The aim is also to show how the design of collaborative housing can encourage social interaction among residents as well as sharing practices. This report offers recommendations to different actors within the housing sector and civil society such as starter groups for new projects and professionals from the private and public sectors.

- The aim of this article is to explore the everyday life experiences of elderly (+70 years) living with young locals and refugees in a collaborative housing project before and during the COVID-19 pandemic in Sweden. The paper discusses the importance of the spatial dimension in the conceptualization of social integration. The main method is a qualitative case study based on observations of settings, document/video analysis, online diary entries made by ten residents and eight semi-structured interviews conducted with the residents. SällBo was conceived as a new type of collaborative housing in which elderly, young locals and refugees share common spaces with the aim of enabling social integration. In this context, COVID-19 interrupted the ongoing processes of living together after four months of moving to the house. The three main themes that emerge from the empirical material are (1) changes in the use of common spaces and social interactions, (2) residents’ resilient coping responses during the pandemic and (3) insights for future design of collaborative housing based on their experience. The pandemic caused a moment of institutional vacuum, which triggered the agency of the residents whilst developing social bonds and social bridges among them. Social connection created in everyday life at SällBo’s common spaces has triggered processes of social integration. The ongoing processes of social integration have included the spatial dimension. We understand social integration as a process that involves people from different generations and ethnic backgrounds, which takes place in common spaces and everyday life as different modes of socialization.

- In developing countries, urbanization is dominated by the growth of informal settlements which represents 40–80% of major cities. The challenges brought up by the growth of informal settlements spans from social-economic to environmental. Previously, upgrading of the informal settlements focused on social-economic aspects such as provision of necessary services for the residents, whereas the quality of the outdoor thermal environment has not received much attention. This paper entails to investigate the potential of upgrading the outdoor thermal environment in informal settlements in the warm humid city of Dar es Salaam, Tanzania through examining the influence of addition of trees with different Leaf Area Index (LAI) and incremental increase of buildings heights. The study uses simulation as a method for analysis of the warm season and calculates the Physiological Equivalent Temperature (PET) as a thermal index. Results show substantial improvement of both microclimate and outdoor thermal comfort. Incremental increase of buildings heights in a street canyon to 12, 18, and 24 m leads to the reduction of PET by 2.5, 2.8, and 3.8 °C respectively at 2:00 p.m. Similarly, applying LAI's of 2, 4, and 6 m2/m2 leads to reduction of the mean radiant temperature by 7.9, 10.1, and 12.2 °C; while PET was reduced by 3.9, 4.7, and 5.6 °C respectively at 2:00 p.m. Nonetheless, upgrading of informal settlements shows marginal influence on the reduction of air temperature. Despite the noted thermal improvement in the studied area, the thermal comfort limits of the warm season were difficult to reach. The findings suggest that addition of vegetation is the economically most effective way for upgrading thermal conditions in informal urban fabric areas.

- In warm humid tropical climates, the outdoor environment defines the lives of the majority of the population in terms of social and economic aspects. Improvement of the outdoor thermal environment encourages social and economic prosperity of the urbanites. This paper explores urbanites’ thermal comfort in the informal urban fabric of warm humid Dar es Salaam, Tanzania. Simultaneously, the study conducted micrometeorological measurements and a questionnaire survey consisting of 1541 respondents for both the warm and cool seasons. The thermal indices, Standard Effective Temperature (SET*), Universal Thermal Comfort Index (UTCI) and Physiological Equivalent Temperature (PET) were calculated. Results show that urbanites of the informal urban fabric areas experience both narrower and higher thermal comfort ranges when compared to both similar climates and other types of climate in the formal urban fabric context. Thermal acceptable ranges were found to be 30.2−32.5 °C and 23.4−27.4 °C for UTCI and SET* respectively. Despite the fact that the results showed the high adaptive capacity of the urbanites, they also revealed the urbanites’ tolerance to high thermal index temperatures due to the limited adaptive options available within the informal urban fabric morphology. The study findings could contribute significantly to the upgrading of informal settlements.

- The thermal environment outdoors affects human comfort and health. Mental and physical performance is reduced at high levels of air temperature being a problem especially in tropical climates. This paper deals with human comfort in the warm-humid city of Guayaquil, Ecuador. The main aim was to examine the influence of urban micrometeorological conditions on people’s subjective thermal perception and to compare it with two thermal comfort indices: the physiologically equivalent temperature (PET) and the standard effective temperature (SET*). The outdoor thermal comfort was assessed through micrometeorological measurements of air temperature, humidity, mean radiant temperature and wind speed together with a questionnaire survey consisting of 544 interviews conducted in five public places of the city during both the dry and rainy seasons. The neutral and preferred values as well as the upper comfort limits of PET and SET* were determined. For both indices, the neutral values and upper thermal comfort limits were lower during the rainy season, whereas the preferred values were higher during the rainy season. Regardless of season, the neutral values of PET and SET* are above the theoretical neutral value of each index. The results show that local people accept thermal conditions which are above acceptable comfort limits in temperate climates and that the subjective thermal perception varies within a wide range. It is clear, however, that the majority of the people in Guayaquil experience the outdoor thermal environment during daytime as too warm, and therefore, it is important to promote an urban design which creates shade and ventilation.
