Bygglovsbefriad vindkraft till småhuset : -Ur ett tekniskt och ekonomiskt perspektiv
In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.
Hantering av småskalig elproduktion : Utveckling av modell för dokumentation och elkvalitetsberäkningar
The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.
Konst Offentlighet Motstånd Om konst som motstånd i den urbana offentligheten - En fallstudie av konstprojektet (O)önskad samhällsförbättring
This thesis is a cultural theoretical case study of the art project (O)önskad samhällsförbättring.Via an analysis of the project, that is based on theories of power, resistance and contemporaryurban development, it examines the construction of urban space, its impact on public art including the ability of art to initiate evolvement of the urban public space.The last decades art has plaid an important role in what is called the creative city; to become attractive nodal points of the global economy, larger cities increasingly invest in art,culture and creative industry. Simultaneously the urban public space is limited to activitiesand expressions of art that are presumed to create economic growth. This introduces animpression of what is allowed and what is not allowed, possible and not possible, wished andnot wished which, as a consequence, evolves the public space. The events during the artproject and the reactions that followed enlightened these limitations. This tells a story, not only about the structuring process of the local urban space, but also important changes that are created as a simultaneous effect at different levels in society, as well locally as globally.
Gradering av vindkraftslägen i Lerums kommun med hänsyn till infrastruktur och läge
The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.
Urban Exploration och jag : Meningsskapande på övergivna platser
Urban Exploration går ut på att utforska övergivna platser. Uppsatsens syfte är att beskriva fenomenet och att diskutera det utifrån ett kulturarvs- och ungdomskulturperspektiv. För att kunna göra detta argumenterar jag, med utgångspunkt i litteraturstudier, för att Urban Exploration bör ses som ett uttryck för senmodernitet, med de särskilda förutsättningar för identitetsskapande och världsuppfattning som det innebär för individen. Som källmaterial har det Urban Exploration-utövarna själva skriver om sin verksamhet på olika Internetsidor använts. Min slutsats är att individen genom att fylla platsen med subjektiv mening skapar dels ett kulturarv, dels sig själv som ett politiskt och historiskt subjekt..
Vindkraftsturism : En studie av teknisk turism med särskilt fokus på vindkraftsparker
This study investigates and describes the phenomenon of ?technical tourism?, in the case ofwind power plants in Sweden. The main purpose of the study is a greater understanding ofa field which to date has remained largely uncharted.Technical tourism is a type of visits to a production site, where the technical aspect ofthe production is the main focal point for the visitor. The definition of technical tourism isbased on concepts within ?Industrial tourism?.
Vindkraftverkens nedmonteringsprocess i Sverige
The first commercially produced wind turbines in Sweden are starting to reach theend of their lifetime after approximately 25 years of producing energy. The cost fordismantling the turbines, according to Ardefors et al. (2009), is calculated to be 1-2 %of the total investment of the wind turbines. The purpose of this master thesis is tomap the dismantling process of wind turbines in Sweden and try to find a sustainablesolution for the future.To make sure that a correct dismantling process takes place, and that the financialaspect is covered, a proposal for a financial guarantee is worked upon. A nationalunanimity will be created through a financial guarantee and the risk will be minimalof a third party getting afflicted.Studies of literature and interviews have been carried out.
Urban odling - exemplet Varvsstaden i Malmö
Detta examensarbete i landskapsarkitektur behandlar ämnet urban odling med avsikten att identifiera vilka möjligheter och begränsningar det finns med odling i staden. Målet med examensarbetet är att uppnå en större förståelse och kunskap inom detta ämne. Varvsstaden i Malmö har valts som ett exempel för att illustrera hur odlingar skulle kunna implementeras i en central stadsdel som är under utveckling.Litteraturstudier har legat till grund för en kunskapsöversikt av olika aspekter av urban odling. En kvalitativ miniundersökning har utförts för att ta reda på hur nyckelpersoner i Malmö från de tre kategorierna; politiker, tjänstemän samt brukare ser på urban odling och dess möjligheter och begränsningar. Kunskapsöversikten om urban odling i allmänhet och beskrivningarna om Varvsstaden i Malmö har fungerat som underlag till idéskisser för hur odling i Varvsstaden skulle kunna se ut.Resultatet av examensarbetet visar på att det finns många möjligheter med urban odling och att det finns mycket att vinna genom att odla i staden.

Vindskador vid stickväg i 1:a och 2:a gallring i Boxholm, Östergötland : i stormen Pers fotspår
Wind damages next to strip roads in 1st and 2nd thinning in Boxholm, Östergötland
Anneli Fransson, SLU, inst f sydsvensk skogsvetenskap, Examensarbete no 108
Wind damage is something we are all familiar with since the storms Gudrun (2005) and Per (2007). Research about strip roads and wind damage is very limited. It is commonly known that the trees next to the strip roads more often fall whit heavy winds, and the purpose of this thesis was to verify this statement. Data was collected from first- and second thinnings at Boxholms Skogar AB, Östergötland. In first thinnings data was collected from both spruce and pine stands and second thinnings only data from spruce stands was collected.
Lantbrukaren som energiproducent : en fallstudie i energisatsningar inom lantbruket
The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production.
Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy.
The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.
Varde ljus!... tyvärr stod det ett hus i vägen. : En studie om dagsljus och vilken plats det har i Stockholms planering
The importance of daylight for humans has been known for a rather long time. Applying this knowledge in the science of urban planning is not very common, at least not in Stockholm, Sweden. Living in a country far from the equator with great differences between daylight and darkness during the year, daylight gets even more important for our wellbeing. This study aims to highlight the subject of daylight planning and contribute to the discussion about how to include daylight in the process of urban planning. By critically observing a new built district in Stockholm and applying guidelines of how to use daylight planning, this paper shows how important it is to include daylight planning early in the process.
Managing urban development : A case study of urban forest?s sense ofplace in Hammarbyskogen, Stockholm
Due to the growing population in Stockholm, some of the urban green areas are beingsubjected to exploitation. Hammarbyskogen is an urban forest in the south of Stockholm andis an example of a green area that is planned to be transformed into an urban environment.This paper investigates key qualities and values of an urban forest of Hammarbyskogenvalued by local inhabitants of the neighbourhoods of Hammarbyhöjden and Björkhagen in thesouth of Stockholm. In addition to that, the study seeks to investigate people?s perception ofthe planned development of the forest as well as investigate how these perceptions andqualities are being incorporated into the process of neighbourhood development.Using text analysis, interviews and discussion forums, findings have been made showing thatthe local inhabitants value the urban forest mostly for its ecological and recreational qualities.Regarding perception of the change, people are either positive or negative to the developmentwhich can be explained by people?s experienced sense of place and place attachment of thearea and the forest itself. The study has also shown that the urban planners rely on localinhabitants? view, as well as on expert knowledge during the process of planning.The results of the study contributes to a better understanding of why and for what purposesurban forests are important for the city dwellers..
Den attraktiva stadens framväxt
The aim of this paper is to analyse how the term attractiveness is interpreted in Swedish contemporary urban planning. The focus is to analyse how the term is discursively constructed and by this highlight the conceptions that exist around what makes a city attractive. We want to emphasize the importance of a deeper understanding of how attractiveness is used in urban planning and how the term is a part of the development of our cities. Given the use of attractiveness as a part of visionary goals for Malmö´s and other Swedish cities future development, our intention, therefore, is to enhance the understanding of what the use of attractiveness means in respect of the creation and construction of power relations in time and place. The framework of our analysis is based on the discourse theory approach and used as a way of understanding how urban ideals is discursively constructed.
Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.
