| Summary: | This report describes the work with generating a proposal for a sustainable, circular and reusable house on Site number 91 in new central parts of Kiruna. New ideas have been developed and tested in collaboration between Kirunabostäder, municipality and research partners. The study includes: generative design (GD) where a software prototype has been developed to be able to generate different building volumes for Site 91 and assess social factors like solar radiation, view, variation and green spaces. A representation of neighbouring buildings was also created to allow for a better evaluation of the generated building. Compared to the earlier developed optimization method the idea with GD is to create more opportunities for interaction between Kirunabostäder, Kiruna municipality and architects.Design for disassembly and reuse was studied in a cooperating master thesis project which resulted in an architect model of a proposed building for Site 91. An environmental assessment for three different building systems was done assuming that the building will be moved and reassembled after 50 years.An inspiring attic garden and orangery has also been developed for increased wellbeing and social comfort. A playing ground based on natural building elements (e.g. unaltered trees) was also developed.Procurement and requirements that can be formulated for circularity and reuse have also been discussed.In a longer perspective, the results from the project can contribute to a more sustainable Kiruna by exemplifying choices for sustainable and circular solutions for Kiruna housing and Kiruna municipality.
