Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö

The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.

Energikonsumtion hos en diskmaskin

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

Utvärdering av labpilot - flödesbatteri : Experimentell studie

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

Rökgaskondensering och skrubber till vedeldade villapannor :

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both Energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

Energideklaration och energiförbrukning för småhus och flerbostadshus

Energy is today a very common topic, not only in Sweden but in the whole Europe. In EU they have given out a directive 2002/91/EG about buildings energy use and throw this they have forced their members to show how much energy their buildings use. In Sweden has the gouvernment established a law (SFS 2006:985) about energy declaration for buildings which demands that the building owner needs to show how much their buildings energy consumption are. Important to know is that this law doesn´t applies for industrial buildings.The report will show what the new law about energy declaration for buildings and appurtenant directions will mean for Riksbyggen. Also energy calculations will be done to be able to compare Riksbyggen buildings with the new law and directions.

Energikartläggning av Fridhemsskolan 16:2

Increased energy consumption in the world has created an increased supply of various fuels, especially fossil fuels. The Swedish government has set up various energy targets for 2020. To reach these goals it?s important to increase the energy efficiency in local buildings such as schools. This work illustrates the breakdown between energy supply and energy losses over the school.

Passivhus vid polcirkeln : Fungerar det?

This report is the product of the course AF101X, a bachelors degree in Samhällsbyggnad atKTH.

The house in this report is located in Kiruna in the north of Sweden, where theclimate is much colder than in the rest of the country.The deepening study of this report is to evaluates how realistic passive housing north of thePolar Circle is based on those facts. The house will to some extent be designed to fit the passivehousing standard.

Utveckling av webbaserad Outlookklient kopplad mot Exchangeserver

Ett nystartat företag ville skapa en hemsida som såg ut och fungerade som Outlook.  Denna sida skulle senare kunna kopplas till Exchange eller något liknande e-postserverprogram. Under arbetets gång så installerades en labbserver med Exchange. När servern var färdig så skulle det gå att koppla upp företaget Teleriks webmaillösning för att sedan kolla om den klarar av Exchange. Målet var att en sida liknande Outlook, till utseende samt funktion, skulle skapas. Denna sida skulle sedan kopplas ihop med en fungerande Exchange server.

En IT-baserad plattform för skolförbättring : En kvalitativ studie av lärares informations- och erfarenhetsutbyte

This thesis has created an image of the exchange of information among teachers in the Swedish upper secondary school. The study indicates that the exchange of information seems to be limited at all levels and the exchange that takes place outside the own teaching team occurs mainly through teachers personal networks. The study also shows barriers that may exist and the opportunities that an increased exchange may generate. From the picture that the empirical material provides and the theory that is presented a discussion is made around how IT can best support the organizational learning in schools. A concrete proposal is that at national level an IT platform should be created, which primarily focuses on materials that are created by its users and has an open architecture with a single login..

Framtidens energilagring : en studie av befintliga samt potentiella metoder fo?r lagring av fo?rnybar el pa? ett ha?llbart sa?tt

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

"Det bästa med skolan" : En elevinriktad studie om motiv och attityder till internationella utbildningsutbyten.

In Sweden, little research has been done on the topic of international exchange programs that various schools offer to their pupils. This study investigates how pupils view these exchange programs, and how in their opinion it affects their learning and their level of motivation. The study also investigates the motives for taking part in or declining an international exchange. To answer these questions a quantitative survey and qualitative interviews with pupils with and without experience respectively was carried out.The study indicates that pupils that have not taken part in an exchange believe that it is a time consuming quest that may affect the student?s results in other courses, which is not a belief shared by the other group.

Konsumentvänlig Energibesparingsmodell : Ett verktyg som hjälper småhusägare att sänka sina energikostnader

Energy awareness is growing among the Swedish population and a one­?to­?two-family dwelling can save energy. The purpose of this paper is to design a tool that helps these home owners reduce their energy costs.The paper develops a model that gives them an indication of how much energy they can save. For the majority of homeowners, the next step in the quest to reduce theirs is most likely an energy audit. Therefore, information to help home owners to get a good energy audit performed is included in the model.A prototype running the operating system iOS is created and validated against existing models, as well as an energy audit. .

Cross-Border Listings and Price Discovery: Evidence from UK- and US-listed Swedish Stocks

Objective: The objective of this study is to examine the extent to which the London stock exchange and the US stock exchange Nasdaq respectively contributes to the price discovery of Swedish stocks listed on the Stockholm stock exchange, the London stock exchange and the US stock exchange Nasdaq.Method: The study is a replicate study of the studies by Grammig, Melvin and Schlag (2000) and Eun and Sabherwal (2003). The methodology is based on the methodology of the latter study. The data material consisting of quoted stock prices for three Swedish stocks on the three stock exchanges at five-minute intervals during a 49-day-period in 2003 has been run through different statistical tests in a five-step process.Conclusion: The evidence of this study shows that prices on SSE, LSE and NASD are cointegrated and mutually adjusting. The evidence suggests that in all three cases, price discovery takes place on the home stock exchange SSE. Moreover, LSE contributes more to price discovery than Nasdaq.
