- Identifying design variations that strike the balance between environmental, energy and cost can be aided using multi-objective optimization. From the resulting Pareto-solutions, selecting a single optimal solution remains a challenge. Thus, research is still needed to increase the practical use of optimization for architectural, engineering and construction (AEC) practitioners. This paper presents the use of an optimization approach where the results and an environmental assessment are discussed with AEC practitioners. The method was tested in two case studies: a prestige tourist cottage and a multifamily residential building. Different superstructures, insulation materials and windows were varied for the cottage’s envelope whilst evaluating life-cycle energy and cost. In addition, the environmental impact in terms of CO2 emissions was evaluated for the initial and optimal design suggestions for the two different superstructures. For the residential building, the insulation material thickness and the windows were varied for its evaluation of life-cycle energy and cost. For the cottage, a report was written and then read by the practitioners and used as a base for future decisions. For the residential building, the results were presented orally for the practitioners. In both cases, it was possible to communicate the overarching results of the optimizations through visual plots, although future research should find ways to also explain the detailed results.

Hållbarhetsutvärdering av byggnader : Case Ripan i Kiruna
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Sustainability includes several parameters, and these can be measured and valued in many different ways. This study focuses on balancing the various parts to achieve sustainability by minimizing energy for heating and energy to produce the materials used in the building as well as minimizing cost for material investment and cost for heating using optimization techniques. This is balanced together with the environmental impact. This report describes an initial study for sustainability optimization of a smaller building. The goal is to develop a comprehensive approach to provide a broader basis of decisions for new construction.The calculation included the building envelope (exterior walls, roof and floors), interior walls and stabilizing elements for different frames of wood (timber frame and CLT).The result from the Ripan Case shows that the timber frame design has the lowest embodied energy and operating energy, and lowest cost for investment and heating during the operating phase. The environmental impact of the timber frame design was also low.

Önskehus på Tomt 91 i nya Kiruna
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- Background We have developed genomic tools to allow the genus Populus (aspens and cottonwoods) to be exploited as a full-featured model for investigating fundamental aspects of tree biology. We have undertaken large-scale expressed sequence tag (EST) sequencing programs and created Populus microarrays with significant gene coverage. One of the important aspects of plant biology that cannot be studied in annual plants is the gene activity involved in the induction of autumn leaf senescence. Results On the basis of 36,354 Populus ESTs, obtained from seven cDNA libraries, we have created a DNA microarray consisting of 13,490 clones, spotted in duplicate. Of these clones, 12,376 (92%) were confirmed by resequencing and all sequences were annotated and functionally classified. Here we have used the microarray to study transcript abundance in leaves of a free-growing aspen tree (Populus tremula) in northern Sweden during natural autumn senescence. Of the 13,490 spotted clones, 3,792 represented genes with significant expression in all leaf samples from the seven studied dates. Conclusions We observed a major shift in gene expression, coinciding with massive chlorophyll degradation, that reflected a shift from photosynthetic competence to energy generation by mitochondrial respiration, oxidation of fatty acids and nutrient mobilization. Autumn senescence had much in common with senescence in annual plants; for example many proteases were induced. We also found evidence for increased transcriptional activity before the appearance of visible signs of senescence, presumably preparing the leaf for degradation of its components.

Hur bör vi handla? Filosofiska tankar om rättvisemärkt, vegetariskt & ekologiskt
- 2012
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Handelns utveckling och globalisering under de senaste årtiondena har inte bara inneburit välståndsökningar för många människor, utan den har också gett upphov till ett antal svåra moraliska utmaningar: de skenande ojämlikheterna mellan rika och fattiga länder, den globala miljöförstöringen och klimatförändringarna samt vad många upplever som en allt mer utbredd respektlöshet för både människor, djur och natur. Vilket ansvar har vi som konsumenter för att göra något åt detta? Är det till exempel moraliskt fel av oss att inte köpa rättvisemärkt och ekologiskt varje gång vi handlar i livsmedelsaffären? Är det moraliskt fel att äta kött? Vilket ansvar har de kommersiella företagen? Kan de fortsätta att enbart fokusera på marknadsandelar och vinster, eller har alla företag en moralisk skyldighet att arbeta aktivt med etik- och miljöfrågor? Och vilket ansvar vilar på våra folkvalda politiker och de internationella politiska institutionerna för att försöka vända den negativa trenden? Denna bok ger en introduktion till aktuella etiska och politiska diskussioner kring fenomenen rättvisemärkt, vegetariskt och ekologiskt. Den är framför allt riktad till dem som vill bidra till att göra världen bättre, och ger därför många råd och tips på hur man kan engagera sig aktivt och mer effektivt. Men boken introducerar också de djupare moralfilosofiska diskussioner som ligger bakom ett sådant engagemang. Hur långtgående skyldigheter har vi i den rika världen egentligen att hjälpa de fattiga och utsatta i det globala Syd? Har djur lika stort moraliskt värde som människor? Och har naturen ett egenvärde, eller är den bara värdefull i kraft av vad den kan ge oss människor?

Me-ness and we-ness in a modified everyday life close to death at home
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overarching aim of this thesis was to describe how family members experienced everyday life with life-threatening illness close to death, with focus on self-image and identity. The thesis comprises four papers, each with a specific aim to illuminate various aspects of the phenomenon under study. The study population consisted of 29 participants; ten family caregivers and five families, including five patients with life threatening illness and their family members. Data were based on retrospective single interviews (paper I), prospective individual, couple and group interviews with the families over six to eighteen month (papers II-III). Interpretive description approach (papers I, II, IV), narrative method (paper III) and secondary analysis (paper IV) were used to analyze data. The findings show how living close to death influences everyday life at home, at several levels (papers I-IV). From the perspective of the dying person, narrations of daily situations was described by four themes related to identity and everyday life; inside and outside of me, searching for togetherness, my place in space and my death and my time. The changing body, pain, fatigue, decreased physical capacity and changed appearance, appeared to influence the dying person’s need for altered knowledge and community, and as a result the patterns of interaction within the families changed. The strive for knowledge and community took place at home, an arena for identity work and the conscious search for meaning, knowledge and community; it was limited by time and inevitable death (paper III). For the family member, life close to death can mean sharing life with a changing person in a changing relationship (paper II). It may mean that everyday life needs to be modified in order for it to work (papers I-IV). New patterns of dependence and an asymmetrical relationship affect all involved (papers III-IV). Daily life close to death is about finding the space to promote the individual self-image, me-ness, at the same time as finding new ways of being a family; we-ness (paper II). Regardless of being the ill person or not, the family members we interviewed had to face impending death, which challenged earlier ways of living together (papers I-IV). From the perspective of the relatives, the everyday life of caring for the dying family member was characterized by challenged ideals, stretched limits and interdependency (paper I). Situations that challenged the caregivers’ self-image were connected to intimacy, decreasing personal space and experiences such as “forbidden thoughts”. The findings suggest that the bodily changes were of importance for the self-image, and that the former approach to the own body was important in the process of experiencing the body. The person living close to death was in transition to something new; being dead in the near future. One way of handling the struggles of everyday life was to seek togetherness, strive to find other persons with similar experiences while sharing thoughts and feelings. Togetherness was sought within the family, in the health care system and on the internet; a sense of togetherness was also sought with those who had already died. The other family members were also in transition as the future meant living on without the ill family member and changing their status to for example being a widow or being motherless. Identity work close to death denotes creating an access ramp into something new; a transition into the unknown. From a clinical perspective, this study emphasizes the significance of creating a climate that allows caregivers to express thoughts and feelings.
