This final thesis is initiated by the wood fuel department at the Swedish forest company Sveaskog as part of a project which also involves two other final thesises. The overall goal of the project is to investigate Sveaskog´s possibilities to produce and sell different wood fuel assortments in Västerbotten and the southern parts of Norrland. The aim of this thesis is to investigate how much wood fuel Sveaskog can produce in the area during the next five years and what that would cost. Furthermore the thesis will investigate the total possible supply of wood fuel from all other possible producers in the area. Treated assortments are forest residues from final fellings, whole trees from direct wood fuel thinnings, non industrial wood and industrial by-products from sawmills. The main effort to investigate Sveaskog´s production possibilities has been made to calculate the possible annual amount of forest residues and fuel from wood fuel thinnings that can be produced.

When I got the opportunity to write this examination did I want to write about something that I both was interest in and also can use in the future. I think it?s going to be difficult to carry on the milk production with only 28 cows. I wanted to investigate the possibility to increase the herd of cows. I also wanted to compare this cost with a new cow house the cows where milked with a robot.

The purpose of this thesis is to analyse and propose improvements to the cost accounting system in use at an airline operating on the Swedish market. The choice of study object is based on the airline?s desire to have its cost accounting system evaluated. During the analysis we have identified a number of points where the current cost accounting system does not correspond to its intended purpose. These points include significant groups of costs not being considered in the current system, potential over capacity is not visible and logic connections between distribution keys and the use of resources are sometimes lacking.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.

Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.

This study describes how a larger investment by a private company in the northern interior can affect a municipality?s economy. The mobility to the municipality is expected to increase and some of the direct and indirect effects that this investment can implicate on their economy are discussed. The method for this study is qualitative. Interviews have been made with the initiative owner of the company LHG Learning Center and with civil servants in the municipality of Lycksele. The conclusions drawn in this study are that the establishment of LHG Learning Centers in Lycksele will include both opportunities and risks for the municipality?s future.

This thesis describes redesign and adaption of a products housing. In order to make it more economical to produce at a lower production volume. The thesis is based upon a prototype that a previous student developed for injection moulding. The goal is to find alternative manufacturing methods, but also to identify parameters that affect the cost of the injection moulding tool.The housing must be tough in order to protect the circuit board inside. But at the same time it must allow sound, light an electrical communication to pass through.

Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.

This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.

For a long time economic tax equalization system in Sweden has been creating dispute between Swedish communities. Despite the main purpose of the system - to reduce disparities and create equal economic opportunities for all communities ? some regions were not satisfied.The main purpose of this study is to determine what extant has equalization tax on investment spending of Danderyd municipality during 2000-2010 year period. The study is based on annual reports and personal interviews. The theoretical frame of the investigation is founded on Fjertorp's classification of investments and public choice theory.The investigation shows that there were no significant changes neither in investment spending or equalization tax during 2000-2010 period, even after the last changes of economic tax equalizations system in 2005.
