Klimatförändringar orsakade av utsläpp av växthusgaser är ett globalt problem. I Sverigestår byggbranschen för en stor del av landets klimatpåverkan och det i kombination meden expansiv samhällsbyggnad utgör en stor utmaning för framtiden. Kunskap om hurbyggbranschen kan minska sina växthusgasutsläpp är därför relevant. I den här studienanalyseras befintliga livscykelanalyser utförda på byggnader för att avgöra hur den totalaklimatpåverkan för en byggnad fördelas över dess livscykel. Studien innefattar ävennärmare analys kring vad som orsakar betydande klimatpåverkan i olika skeden av enbyggnads livscykel. En inventering av befintliga studier utfördes med metoden för ensystematisk litteraturöversikt som grund där ett sökprotokoll utformas med sökord ochsökstrategier. Materialet har sedan systematiskt gallrats enligt satta kriterier tills detslutgiltiga urvalet resulterade i 17 studier till analys. Dessa studiers resultatsammanställdes enligt moduluppdelningen i standarden Hållbarhet för byggnadsverk SS-EN 15978:2011, både i absoluta tal och andel av byggnadens totala klimatpåverkan.Modulerna, som motsvarar skeden i en byggnads livscykel, jämfördes med varandra föratt utröna hur klimatpåverkan var fördelad över livscykeln. Bidragande faktorer inomvarje modul studerades för att identifiera faktorer med betydande klimatpåverkan somorsakade en stor skillnad mot övriga moduler. Analysen visar på två skeden som harbetydligt större klimatpåverkan än övriga: produktion av material och konstruktionsdelarsamt drift av byggnaden. Faktorer som är betydande för dessa två skeden är användandetav betong, byggnadens beräknade livslängd samt andelen fossil el som används viddriften av byggnaden framförallt för uppvärmning. Analysmaterialet innehöll storavariationer i syfte och därmed tillvägagångssätt vilket försvårade analysen och visar påbristen av ett gemensamt arbetssätt. Denna studie synliggör behovet av fortsatta studiersom berör biomaterial som kolsänka, framtida arbetssätt med livscykelanalyser, andrafaktorer som markanvändning, skogsbruk och ekonomi samt miljöpåverkanskategorierutöver klimatpåverkan. Detta kan leda till ett utvecklat arbete med att minskabyggbranschens klimatpåverkan. / Climate change as a result of greenhouse gas emissions is a global issue. A large part ofSweden’s climate impact originates from the construction industry and in combinationwith an expansive urban planning it constitutes a big challenge for the future. Knowledgeof how the construction industry can reduce its greenhouse gas emissions is thereforerelevant. In this study, previous life cycle assessment studies on buildings were analyzedto determine how the total climate impact of a building is distributed over its life cycle.Included in this study is also a closer look on what causes considerable climate impact inthe different stages of a building’s life cycle. An inventory of previous studies wasperformed based on the method of a systematic literature review were a search protocolwith search phrases and strategies are constructed. The material went through a systematicscreening process according to certain criteria that resulted in 17 studies used for analysis.A matrix was made of the result of these studies according to the modules in the Europeanstandard Sustainability of construction works EN 15978:2011, with both absolutenumbers and share of total impact. The modules, which represents different phases in abuilding’s life cycle, were compared to each other to establish how climate impact wasdistributed over the life cycle. Contributing factors in each module were examined toidentify factors with considerable climate impact causing modules to differ. The analysisshowed two phases with noticeably bigger impact than the rest: production of materialsand construction parts and the buildings use phase. Factors important for the impact fromthese two phases were the use of concrete, the buildings assumed life span and the amountof fossil electricity used during the use phase, in particular for heating. The analyzedmaterial contained big variations in goal and scope and therefore also assessmentapproach which complicated the analysis and shows the lack of a unified assessmentprocedure. This study shows the need for more studies concerning embodied carbonemissions and the use of bio-based materials, strategies for using life cycle assessmentsin construction, other factors with impact on a building’s sustainability such as land use,forestry, economy and environmental impact categories besides climate change. Thiscould lead to further developed work on reducing climate impact from construction.

According to the national climate policy framework adopted by Riksdagen (the Swedish parliament) 2017, Sweden should reach zero net emissions of greenhouse gases in 2045. For this to be successful, the construction and real estate industry, which annually accounts for one fifth of Sweden’s territorial greenhouse gas emissions, needs to minimize its emissions. One step towards reducing the emissions is to track and quantify them and that is why in 2022 a new law will come in to force that requires the developer to make climate declarations on all new buildings. This study has investigated how and when climate calculations of planned buildings should be carried out in order to be as beneficial as possible. Furthermore, the study examined material choices and emission allocation in order to reduce greenhouse gas emissions caused by the construction process. A building information model (BIM model) of an educational building which is planned to be built, served as a case study for this project. The BIM model was imported to a spreadsheet program in order to create three different versions of the building in three common framing materials; wood, concrete and steel. A list of all used building components, construction resources and associated quantities was produced and exported for each model. The list was imported to a climate calculation tool, based on Life Cycle Assessment (LCA), to manually link the construction resources with their corresponding LCA data. General waste fractions and general transport scenarios were entered for each construction resource. Theresults showed that the wooden frame model emitted 28 %less carbon dioxide equivalents (CO2e) than the concrete frame model and 22 % less than the steel frame model. The wood frame itself generated a 54 % less greenhouse gas emissions than the concrete frame and 45 % less than the steel frame. Concrete and insulation were the two resource groups that caused the greatest climate impact in five out of six cases. The production of the building components caused 88–90 % of the total climate footprint for all three models. Transport of the building components to the construction site and resource waste at the construction site both caused between 4–6 % of the climate impact in all models. The study also found that the climate calculations should be carried out as soon as the general architectural model of the building is created, in order for the calculations to serve as a decision basis in the project planning where design choices are made. The price for the climate calculations at an early stage in the construction process is low because the BIM model is relatively simple and therefore the calculations are not time-consuming. If the climate calculations occur at a later stage of the construction process, the emission figures become more accurate, but the price for the calculations increases. In addition, it is more difficult and much more expensive to make changes at a later stage. Thus, the probability is that the climate calculations will not be used in any decision. Nyckelord

The recent political events in Egypt, Libya, Yemen, and Tunisia (2011) have confirmed the key role of social networks (SNSs), as well as online political news in supporting citizens with their self-determination. Furthermore, “changes in the media landscape present new challenges for scholars interested in the relationship between the media and civil society. Additionally, the explosion of the Internet that started in advanced democracies and has spread through much of the globe provides new and unexplored pathways for communication. Moreover, the inclusion of the Internet in the media environment raises new questions for citizens, politicians, researchers, journalists, and government” (Oates, Owen & Gibson, 2006, p. 1). This study looks at the relationships between young people’s exposure to political news on the Internet and their political awareness. It develops and applies an index for political participation composed of several variables measuring political interest, discussion, knowledge, and participation. The survey among students in both countries was administered in Arabic and German, while the master questionnaire was developed in English. The survey was conducted between April and June 2010 in Egypt at Minia University and in Germany at Technical university of Dresden. The sample size was 1000 (500 in each country) students from several departments representing different academic fields: three departments of Engineering, three departments of Humanities and Social Science, and finally three departments of Natural Science. The study’s main research question was: “What is the impact of students’ exposure to political news on the Internet on their political awareness and civic activities?” The researcher started from the hypothesis that heavy use of political news on the Internet is positively related to political awareness. A further research question aimed at gauging the role of intervening variables such as gender and field of study for the relationship between the use of political news on the Internet and the level of political awareness. Results show that there is a positive relationship between using political online news and political awareness. German students’ political awareness for German students was higher than Egypt student’s political awareness (M=63.02, SD=15.65, comparing to M=45.72, SD= 17.65 for Egyptians).

Diese Arbeit verbindet zwei Perspektiven, nämlich den Blick auf die soziale Praxis des digitalen Ungehorsams mit dem anhaltenden Diskurs über zivilen Ungehorsam in der politischen Theorie. Digitaler Ungehorsam entwickelte sich im Verlauf der Evolution digitaler Informations- und Kommunikationstechnologien in überraschendem Facettenreichtum: vom BTX Hack des Chaos Computer Clubs über den Widerstand der Cypherpunks für die weltweite Verbreitung von Verschlüsselung hin zu Anonymous, Aaron Swartz und Edward Snowden. Reload Disobedience plädiert für eine Revision des dominierenden Verständnisses von zivilem Ungehorsam und stützt sich dabei auf Theorien von Hannah Arendt, Michael Walzer und Etienne Balibar. Viele Beispiele in der Geschichte des digitalen Ungehorsams werden diesem neuen Verständnis durchaus gerecht, doch gibt es gleichzeitig Faktoren, die weitere Fragen aufwerfen: Kann ziviler Ungehorsam anonym sein oder automatisiert durchgeführt werden? Wie verändert sich das kollektive Handeln, das maßgeblicher Teil der Tradition zivilen Ungehorsames ist, durch die globale Vernetzung? Um diese und andere Effekte digitalen Handelns zu verstehen, diskutiert die Autorin die Entscheidungen der digital Ungehorsamen sowie Möglichkeiten und Grenzen digitalen Handelns im Kontext demokratie-theoretischer Überlegungen. Eine Kernthese der Arbeit ist, dass ziviler Ungehorsam in digitalen Formen potentiell eine neue Direktheit des Politischen erzeugen kann. Gleichzeitig muss sich diese Praxis einer besonderen Unsicherheit sowie neuen Risiken und Herausforderungen stellen, um dem demokratischen Geist des zivilen Ungehorsams unter neuen Bedingungen gerecht zu werden. / This work combines two perspectives, namely the social and activist history of digital forms of disobedience with the ongoing discourse around civil disobedience in political theory. In the course of the internet’s evolution, digital disobedience developed in a surprisingly multifaceted nature: From cases like the BTX Hack of the Chaos Computer Club, to the Cypherpunks and their effort to spread encryption, from Anonymous to Aaron Swartz or Edward Snowden. This work argues for a broader understanding of civil disobedience than the mainstream in political thinking suggests based on arguments from a radical democratic line of thinking, inspired by Hannah Arendt, Michael Walzer and Etienne Balibar. Many cases of digital disobedience meet the spirit of this new understanding, while at the same time their digital nature provokes a new set of questions as well. For instance the question, if civil disobedience may be anonymous or even automated. How does the internet change collective action which is often seen as a core element of the tradition of civil disobedience? The author discusses the choices and principles behind digitally disobedient action as well as the possibilities and limits of digital action in the context of democratic theory. She shows that civil disobedience in digital action even develops a new directness of encounter that adds a new potential to this delicate form of political action. Nevertheless, digital practices of civil disobedience are at the same time precarious and faced with new risks and challenges, like automation of and the risk of elitist tech-avant-gardes overriding the democratic spirit that civil disobedience is rooted in.
