The main method we used were semi structured interviews with a fairly opened framework.

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.

When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.

This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.

This is a work that look at the factors that affect future monthly costs when buying a house in Sweden and which options are the most financially favorable over a 30 year period. The work also examines whether it is economically beneficial to invest in a low-energy house regardless of geographic location in Sweden, and discuss about whether a calculation template can help individuals to choose more environmentally friendly options. The work has been limited so that a certain number of predetermined factors and its measurable values have been developed with the help of a literature study. The factors chosen are building type, climate, heating systems, loan interest rates, energy prices, energy price increases, inflation rates and down payment. These are then combined into 72 different calculation cases which get put in a calculation model made in excel.

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

Does goodwill affect the cost of capital? Goodwill is an asset which is characterized by much uncertainty regarding both what it is and how much it is really worth. Based on economic theory about information risk and principal-agent problems as well as theory regarding the cost of capital we test for the hypothesis that debt and equity investors perceive goodwill as something risky and hence demand compensation for taking on this extra risk. The proxies used for the cost of capital are cost of debt, beta and the EP-ratio. On a general level we find that increasing the level of goodwill seems to result in higher cost of capital as represented by the three proxies.

Chunks and Tasks is a programming model based on the C ++ programming language. This programming model is used for electronic structure calculations, among other things.The purpose of this project is to improve the CHT-MPI software library for Chunks and tasks, so that calculations of matrix-matrix multiplications are performed more efficiently than they do with the existing software library. The software library is based on the work stealing method, which is a method the software library for Chunks and Tasks uses for the distribution of the calculation work. The considered way to improve the software library is by modifying the work stealing method in a way that makes the distribution of calculation work happen in a more efficient way , which will lead to calculations performed faster than before.Two different modifications of the work stealing method were tested and it led to two new methods, Method 1 and Method 2, which distributed the calculation work differently. Method 1 did not give results that were compatible with the theory, since the calculation time with this method was much longer than the previous method.

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

The purpose with this study is to compare different systems of grain storage from a financial point of view. Grain that is supposed to be fed to laying hens. The systems that were compared were different airtight storage of grain and a system of conventional storage. To make this case study I choose to compare four different systems. In the case study there was one system with bin drying of the grain, two systems with airtight storage of the grain and one system where you buy dried grain during the season. I made several of capital investment appraisal where I found the cost of each system, then I took the cost and divided it with the total grain use and calculated the cost for each kilogram of grain, and also the cost of the feed. Then I compared the cost from my case study with the cost of buying feed. All the systems except for one, gave a lower cost for the hen feed than buying feed from a dealer The best system, witch were bin drying lower the cost with about 80 000:- SEK.

In today's society, the availability of energy plays an integral part in our everyday lives. Unfortunately, the price of energy in Sweden has increased in recent decades. A large part of our energy consumption goes to heating modules for houses, where heating methods that depend on energy sources such as electricity, district heating, fuel oil, gas and biofuels are the most common ones. During the winter period, the increase in energy costs becomes significantly evident, especially for small property owners. This increase in energy cost is most noticeable for home owners with electric heating.This thesis is written at the Halmstad University, in cooperation with a company, which makes parts of this thesis confidential.
