Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.

Sverige är idag i starkt beroende av importerade oljeprodukter för att driva de dagliga transporter som krävs för att samhället ska fungera. Kraftigt ökade priser på olja, eller en slopad internationell oljehandel skulle få ödesdigra konsekvenser för Sverige. Samtidigt är Jordens klimat i förändring, varmare temperaturer leder till smältande inlandsisar och detta till stor del på grund av världens oljeanvändning. Denna rapport behandlar de ekonomiska aspekterna kring biogastillverkning för ett Väster- och Norrbotten självförsörjande inom drivmedel för vägtransporter. Rapporten utreder huruvida denna självförsörjning skulle vara möjligt med avseende på tillgång utav råvaror för biogasanläggningarna.

Swedish dairy production has during the last decades undergone considerable structural rationalisation and the number of dairy herds has decreased to less than 7000. At the same time the average herd size has increased and a large proportion of those investing in new buildings today choose automatic milking (AM). During 2008 more than ten percent of the Swedish cows will be milked with AM. The development has been faster than expected and the need for consulting has increased rapidly. This study aims to evaluate whether a check list originating from the FRISKKO (?healthy cow?) programme can be a useful tool when assessing how well the herd functions in various areas.

En revisor kan inta två roller som granskare och som rådgivare. Den huvudsakliga revisorsrollen ses ofta som en extern granskare av sina klienters verksamheter och den som lämnar en slutgiltig bedömning av företaget. Därutöver finns ytterligare en roll då revisorn är engagerad i klientföretaget och bistår med tilläggstjänster i form av rådgivning gällande verksamhetens redovisning och bokföring. För att revisorn ska fylla sin funktion i samhället är dess oberoende och förtroende två viktiga grundstenar för professionen och revisionsbyråns storlek anses ha en viss inverkan på detta. En revisors två roller kan beskrivas som en balansgång mellan dennes granskningsroll respektive rådgivningsroll med en tyngdpunkt som utgörs av kärnan för revisorsprofessionen samt dess grund.

Humanity stands before a huge challenge to lower its emissions of carbon dioxide and its use of energy at the same time as the global population is rising and the developing countries are being industrialized. A lot of newly built buildings are due to this challenge, designed to be more energy efficient but also use renewable energy resources instead of pollutant fossil fuels .Solar energy is one of the purest forms of energy that exists in abundant amounts, which is why it is most likely that it could come to play a major part in the future energy market. The main purpose of this report is to investigate the possibility to implement a sustainable energy system with solar thermal heat and  heat storage as main sources of energy in the neighborhood ?kvarteret Lagern?, which is the area where the old football stadium ?Rasunda Stadion? was located. New developments within different heat storage techniques have opened up new approaches to enable buildings an all year round heat supply from solar energy. This report will focus on heat storage in boreholes. At the present here is only a preliminary plan of how the neighborhood is supposed to be designed.

Att tillägna sig sin bostad är en viktig aspekt för att kunna känna sig hemma i sin egen bostad. Arkitekten Ola Nylander presenterar i sin forskning sju egenskapsfält (material och detaljer, axialitet, omslutenhet/öppenhet, rörelse, rumsfigurer, ljus och rumsorganisation) som kan fungera som måttstockar för hur väl en lägenhet går att ta till sig. Uppsatsen utgår från de sju egenskapsfälten och undersöker, genom dem, hur de boende upplever trivseln i sin bostad. Alla bostäderna i undersökningen är placerade i ett passivhus på fastigheten Flaggskepparen 5 i Västra Hamnen Malmö. Syftet med uppsatsen är att undersöka vilka egenskapsfält som är viktiga för hur de boende upplever trivseln i ett nyproducerat passivt flerbostadshus. 9 stycken kvalitativa intervjuer har därför genomförts med de boende i fastigheten. Dessa intervjuer har varit mellan 20 och 60 minuter långa och genomförts på plats i respondenternas lägenheter (alla utom en).

The purpose of this study was to develop recommendations for using more efficient lighting and better graphic design to create a more uniform structure in the exhibition hall ?Road to the past? in Jönköping County Museum by answering the following questions at issue:1) How are the objects in the exhibition hall ?Road to the past? exposed today?2) How can you use lighting and graphic design to create structure in the exhibition and strengthen the expression in the exhibition?Our work is based on observations and open group interviews. We observed the exhibition hall ?Road to the past? during day and evening. In the same hall, we observed a guided tour that we followed up with open group interviews.

This degree project has been carried out by Carolina Rapp and Jenny Tauson, students at Innovation and Design Engineer program at the Faculty of Technology and science at Karlstad University. The project was carried during Spring of 2009 and took 15 weeks of full time work.  Doppelmayr/Garaventa Group is an Austria/Switzerland corporate group and its associated company Doppelmayr Scandinavia lies in Sunne, Sweden. Doppelmayr/Garaventa Group is the world quality and technology leader in ropeway engineering. The degree project goal was to develop a new shaping of a surface lift. There are two kinds of surface lifts, platter and T-bars. The two kinds of surface lifts have some variation in design but only minor differences.

This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.
