Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.

Sapa är en av de största tillverkarna i världen av aluminiumprofiler. Sapa Building System AB är ett dotterbolag till Sapa group och är en av de största leverantörerna i Europa på byggsystem. Några av deras produkter är bakdörrarna RD 3010 och RD 3020 för lastbilar, släp och trailers som från början var ämnade som sidodörrar. Som bakdörrar är de överdimensionerade då sidodörrar hade högre hållfasthetskrav. I dagens läge väger och kostar de mer än nödvändigt där av önskar Sapa Building System AB en nyutveckling av bakdörrarna.Målet är att omkonstruera bakdörrarna RD 3010 och RD 3020 så att de blir lättare, smidigare och billigare genom att konstruera en ny kantskoning till Sapa Building System AB:s befintliga aluminiumlämprofiler.Arbetet har resulterat i att ritningsunderlag för nya profiler har tagits fram där man valt att limma ihop dörrarnas delar istället för att nita.

Previous studies of stress and coping regarding urban bus drivers describe an unhealthy occupation in areas of psychological and physiological factors. In the present study a social constructionist approach was used to investigate Swedish urban bus drivers' constructs of stress and coping regarding passengers. Semi-structered interviews were performed with ten bus drivers, nine males and one female. The data was transcribed verbatim and analysed with the program QSR NUD*IST.Three main themes where found; passanger related context, coping strategies and promoting circumstances. The bus drivers' constructs describe passanger relations as part of a stressful work environment where successful coping is problematic..

Projektet grundar sig i grannarnas motvilja till en kontroversiell byggnation vid Högalidsparken. Parker är som regel inte bebyggda och bebyggelse med bostadskaraktär minskar parkens offentlighet. Detta förslag bidrar med att utöka parkens yta och genom att hålla bygghöjden låg, fortfarande bibehålla grannarnas utsikt över parken. I Stockholm råder också brist på utrymmen där flyktig eller säsongsbetonad handel kan ske innomhus, därför innehåller förslaget även en marknad inriktad främst till privatpersoner och små företag..

The design of the building envelope affects the energy consumption of a building. As the energy requirements for new buildings are becoming more demanding, the performance of the building envelope must be improved. Energy efficiency and durability are important attributes to consider.This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new, climate smart, residential area in Uppsala, Sweden.Studies and analyses on energy consumption and moisture transportation were made.

The study took place at a food corporation in Växjö, Sweden. It describes a building that contains four tanks in which glucose syrup is stored. The purpose of the study was to calculate the amount of heat that leaves the building and the amount of heat that is supplied by the installed heating equipment. Before the calculations could be implemented, all the systems that supply the building with heat had to be examined. With a small amount of information from earlier studies, the work to gather all the data necessary for the calculations began.

The way we design our cities today will affect the living conditions for future generations. Planning as a discipline can become crucial to attain a sustainable urban development with an increased quality of life among the urban population and an improved environment. Urban Agriculture in the Sustainable City -a case study in Managua is a Diploma Work that deal with poverty issues, aspects of sustainability and development work. We have had a theoretical starting-point, but our focus has been on the case study i.e. the practical part, that we carried out in Managua, the capital of Nicaragua. Today about half of the worlds 6,3 billion people live in cities. The demographic growth of the countryside has declined, while the population in the cities is considerably increasing.

This thesis aim to investigate the living conditions among marginalized habitants of suburbs in the Swedish welfare state. To approach an understanding of the complexity of marginalized urban areas, this thesis focus on studying the Stockholm suburb Husby in a context of the May riots 2013.The research method used is qualitative interviews with seven informants, who have a connection to the Husby area.The theories applied to the empirical material is Gösta Esping-Andersens theory on welfare state regimes and Loïc Wacquants theory on advanced marginality, also known as ?The new urban poverty?.By observing the complexity of the Husby riots in a contextual aspect of the Swedish welfare state and the living situation in Husby, the analysis has shown that the Swedish welfare model is going through a changing process. This process means a shift from a social democratic welfare model towards a more liberal regime, with an increased privatization of public welfare and a focus on individual responsibility regarding the citizens own living conditions. Husby as an area is characterized by a low socioeconomic status, a high level of unemployment and poor school results.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

The construction industry can contribute to a healthier sustainable community. A development that is going on right now is by using more prefabricated volume- and plan elements on the construction sites. Building with this method not only provides a benefit to the environment, but also reduces production rates by taking up to 80 percent less time to build. By building in this way it will be easier to recycle and keep all the material that otherwise would go to waste. Also by building inside a protected environment, the material retains its good quality.This report will take forward proposals on further development of prefabricated volume element of wood, by first presenting this construction methods advantages and disadvantages..

A variety of demands have to be considered in the design of a new opera house in Galärvarvet. All possible viewpoints are important to be aware of, as is the need for the new building to be a contrast to the already existing opera house in Stockholm. The restricted site also makes a multitude of demands on the building's design.By rationalizing the layout and structure and also by making the footprint smaller, the complex building of over 30 000 square meters can be fitted and blended into the existing physical context. Unlike the existing opera house in Stockholm, the new opera house shows the rationality and the advanced technology that lies behind the scenes and becomes the character of the entire building. Through the dynamic façade, the new opera can convey any character it so desires, just like scenes do through different settings.

Urban operations is one of the most difficult challenges a modern army can be tasked with. These challenges have been studied in history and present with various perspectives, but rarely from a combat engineering point of view. The purpose of this thesis has been to study the urban capabilities of a Swedish combat engineer company by examining if it can perform similar combat engineering fieldwork that supported the basic capabilities mobility, defence and effect in Operation AL FAJR, Fallujah Iraq 2004. These are the capabilities a Swedish engineer company are primarily designed to support in urban operations.For example, the study of Operation AL FAJR has shown that fieldwork supported mobility with breaching minefields, obstacles, walls and doors. Defence by creating defensive positions and obstacles.

There are currently 2160 buildings in Sweden that are protected by law with the designation as a cultural heritage building, which is the strongest protection that can be obtained for a building of cultural historic significance. The purpose of this thesis is to research how strong and sustainable the protection of such a designation is and how you can motivate a revocation. Furthermore, this thesis aims to give an overall insight into all cases where there has been a revocation.To achieve the protection of a designation as a cultural heritage building, the object has to be of outstanding interest on account of its cultural historic value. In the first part, this thesis gives a short historic background of the cultural heritage law and its terms, like outstanding interest and cultural historic value. The County Administrative Board's documents about revocation are the main source for this research.There have been 24 cases of revocation and the frequency of such cases has increased in the past ten years.

Uppsatsen behandlar temat urbana tillväxtstrategier i svensk planering. Studien syftar till att undersöka hur översiktsplaner har påverkats av entrepreneurial city, platsmarknadsföring och kreativa klassen som alla är olika teorier om urban tillväxt. Undersökningen utgår ifrån fem kommuner med en översiktsplan från tidigt 90-tal och en aktuell plan antagen omkring 2010. Översiktsplanerna studeras utifrån de valda teorierna (entrepreneurial city, platsmarknadsföring och kreativa klassen) om urban tillväxt för att ge förståelse för hur strategierna i kommunernas översiktsplaner har påverkats av teorierna. Den genomförda undersökningen visar på en förändring över tid som pekar mot mer tillväxtorienterad planering..

This diploma work addresses the question of how much energy is spent whenmanufacturing the components of a building as well as of how much energy is used inthe production of a building. The object of the studies is BioCentrum at the SwedishUniversity of Agricultural Sciences in Ultuna just outside the city of Uppsala. The aimof the work was to investigate how much energy was consumed when manufacturingand production in relation to the management, how many years the production wasrepresented. It was also a study in how mature the construction industry is to answerhow much energy was consumed in manufacturing.In order to get these answers a question form was developed and sent to thesuppliers to BioCentrum. In this form they were to respond to the quantity suppliedto BioCentrum and the amount of energy was spent when manufacturing thecomponents.
