A third party access to district heating networks has been proposed in Sweden, to increase the competition on the district heating market. Such third party access could create opportunities for the agricultural sector as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel. The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant. In the study, an estimation of the profitability has been made by estimating the cost of the investment, personnel, operating and maintenance costs and costs for the fuel and ash handling.

Denna uppsats syftar till att undersöka användandet av parallella prototyper i flera iterationer vid arbetet med en behovsanalys hos ett företag. Som grund för arbetet ligger ett uttryckt behov av ett verktyg för sammanställning och presentation av material skapat av designbyrån the Apartment i Stockholm. Utifrån den förfrågan som gjordes från byrån i ett första skede, togs två prototyper fram för att stödja diskussionen om företagets faktiska behov, som i vissa fall inte stämmer överens med de uttryckta behoven hos en beställare. Dessa första prototyper syftade till att skapa en bättre förståelse för företagets arbetssätt och konceptuella behov. Efter att prototyperna gåtts igenom skapades en andra omgång prototyper, den här gången mer utvecklade, och inriktade mot att ta reda på mer funktionella behov i processens slutskede (presentationsdelen).

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

Since the beginning of the new millennium the world?s population has increased exponentially fast. The majority of this growth has been accommodated for by urbanization of the developing world. This in turn has lead to a wide spread of informal settlements. Thus, areas of urban slums, that have risen illegally on the marginal lands within and at the periphery of the formal city.

Often, the green is handled as an opposite to the built, but if it could be seen as a part of the built and the society, the planning will be easier to handle. The thesis work wants to create a method that treats villages in an analytic way in a context; with green, blur, grey and all the other colors that together are the completeness.This master's thesis is made to be used as foundation in detail plannng in the municipality of Örkelljunga. Target audience is on one hand those who work with planning and green matters in Örkelljunga municipality, but also other planners who work with landscape.Literature in the field of green city planning has been studied and 30 methods for analysis have been valued. The method for analysis that has been used in this work is a merging of ten different methods and has included literature studies, sketches, interviews and work on spot. The ten methods are consciously chosen to together make one comprehensive and true image of the village, as far as it is possible.

Sweden recently changed the national regulation of chimney sweeping. This study has two purposes. The first purpose is to evaluate the effect of this reform to see if the new regulation has led to an effect in terms of increased chimney fires in single-family houses and for the wood-burning and oil-burning stoves, respectively. The second purpose is an updating of a previous study (Mattsson 1994) of analysis of society´s benefits and costs of different alternative sweeping frequencies for wood-burning and oil-burning stoves. This study also has a secondary purpose to examine the extent to which the local sweeping rules vary with climate conditions.  Mattsson, based on his results, proposed that the sweeping requirements for oil-burning stoves should be reduced from twice a year to once every second year and for wood-burning stoves the sweeping should be reduced from four times to once each year.

This report deals with prefabricated bathrooms and the advantage, during the production process, they have compared to ordinary produced bathrooms.The work is done together with the building company JM. The common task is to investigate if the manufactures, in spite of standardized design can meet the concept of JM, i.e. high flexibility and adjustment towards the customer. In JM they are doubtful to the method, as they did not yet worked with prefabricated modules and think that the choises for the costumer will be limited.There will be a short resume of the progress of the bathrooms and its importance as sanitary and wellbeing.The recent problems with damage caused by damp in bathrooms. Have resultade in regulations.

Trading financial securities at stock exchanges and other authorized market places is today a particularly important socioeconomic phenomenon in many industrialized countries. A well functioning securities market is crucial for the economic development in these countries. The modern trading with stocks and other financial securities is characterized by the fact that the majority of the transactions at the stock exchanges are carried out through various intermediaries. The ultimate counterparties that are involved in a securities transaction (the seller and the buyer) are often unknown to each other. The anonymity in the securities trading implies several interesting legal problems.

The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.

This dissertation aims to explore how an investment appraisal differs depending on if it is conducted by a municipal or a private real estate company. Municipal and private real estate companies are not performing on totally equal terms in the property market. A municipal company in Sweden has a public service mission. The consequence due to that mission is that they have limited yield potential but on the other hand the right to certain subsidies. They are also limited by the law of public purchasing (in Swedish: Lag om offentlig upphandling) in the investment process.

Åtta semi-strukturerade djupintervjuer genomfördes i syfte att kartlägga svenska formgivares och förlagsanställdas strategiska och kreativa arbetsprocess samt olika attityder vid arbetet med praktverk och coffee table-böcker. Dessa böckers termer och definitioner diskuterades även, samt boktypens förut-sättningar och utmaningar på marknaden. I denna rapport presenteras funna teman rörande dessa tankemönster och attity-der, samt en generell beskrivning av arbetsprocessen. Produktionen av coffee table-böcker och praktverk fanns vara komplex på grund av att den involverade många personer, tog lång tid i anspråk, var kost-sam och hade relativt små vinstmarginaler vilket därmed kunde förenas med vissa risker. Respondenterna upplevde generellt arbetet som spännande, roligt och givande.Studien belyser även förekomsten av en viss diskrepans vad gäller associationerna till termerna ?coffee table-bok? och ?praktverk?.

Uppsatsens syfte var att studera industriellt köpbeteende för branschen för prefabricerade trähus. En teoretisk studie har därför genomförts där köpsituationer och dess påverkan på köpprocessen, köpbeslutsgruppen samt kriterier för val av leverantör studerats. Datainsamling har skett genom telefonintervjuer med tre av Sveriges fyra största byggföretag, intervjuerna har genomförts med personer med god kunskap när det gäller inköp av prefabricerade trähus på dessa företag. Resultatet av vår uppsats visar att den den vanligaste köpsituationen för företag som köper prefabricerade trähus är nya köp men att det även förekommer direkta återköp främst genom avrop på ramavtal. De personer som ingår i köpbeslutsgruppen är initiativtagare, användare, köpare, influerare, beslutsfattare och informationsbevakare, vilket överensstämmer med teorin.

Nearly 50 years after the building of the first million programme neighbourhoods many Swedish municipalities faces an extensive restoration work in these neighbourhoods which during their relatively short lifetime have acted as a target for a large amount of criticism. Öster in Gävle is a million programme neighbourhood that has gone through an extensive restoration between 2001-2009 with the aim of improving the living environment. Improvements have been made in the outdoor environment, to the facades of the houses and the entrances? of each building. The purpose of this study has been to investigate the effects of the renewal in the physical outdoor environment for those who live in the neighbourhood.

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.
