Solvärme för en skola i Lerum. Studier av olika systemalternativ.

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.

Metoder att förhindra nedisning av vindkraftverksblad

ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.

Universella rättigheter och partikulära behov : En studie om internationellt jämställdhetsarbete utifrån FN: s Kvinnokonvention

The aim for this thesis is to study the international gender equality work from a perspective of the concept of universalism and particularism, with the United Nation?s Declaration of Human Rights, and especially -?The Convention on the Elimination of All Forms of Discrimination Against Women?, in focus. The shadowreports of Namibia and Sweden are used as examples of how countries with different historical, political and social contexts are working with gender equality.A theroetical framework is constitued by theories as postmodernism, postcolonialism and feminism with basis from social constructionism. The thesis is methodological influenced by Critical Discourse Analysis. Notions from former studies were also used as tools in the analysis.

Termisk Vattenpump

 This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.

Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet

There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes. District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption Research), which has focused on climate adaption in the Nordic countries.

Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Isomorfismer i kyrklig organisation : En ecklesiologisk undersökning av Svenska kyrkans regionala nivå

This thesis examines the regional part of the Church of Sweden. Existing as a Lutheran evangelical church since the declaration in Uppsala in 1593, the Church of Sweden became completely separate from the state in the year 2000. Apart from a small piece of legislation by the Swedish parliament, the now former state controlled church were to act on their own. This development can be seen as a result of several decades of discussions. The author is raising the question about the roll and function of bishops and dioceses in the Church of Sweden.

Något om misstag inom avtalsrätten : särskilt om gränsdragningen mellan förklaringsmisstag och motivvillfarelse

According to Swedish contract law, a mistake in contract can be categorized as either an error concerning the content of the agreement or an error in motive. An error concerning the content of the agreement could be described as a divergence between a party?s intent and his declaration, while an error in motive is a mistake about the reasons why a party would like to agree to the contract. The borderline between these two types of mistakes is based on Savigny?s theories on echt (error in motive) and unecht (error in content) mistakes.

Implementation of renewable energy in the Republic of Moldova : society and landscape in transition

The Republic of Moldova, situated in eastern Europe and a former part of the Soviet Union, is now experiencing a phase of transition in both society and landscape. They have hardly any fossil depots and are currently dependent on Russian gas, with 97% of their energy needs imported. The new elected government wants to move towards the EU and this is generally seen as the way to grow and reduce poverty. Security in the energy sector is important and one tool is to increase the use of renewable energy sources. Through interviews, texts, and visits I have studied the implementation of renewable energies (RE) in Moldova through a society development perspective. The study has aimed to investigate the sociotechnical complexity of this subject and to discuss the potentials and way of dealing with the subject in the specific cultural context of Moldova.

Solenergi i Norrra Djurgårdsstaden

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

Bygglovsbefriad vindkraft till småhuset : -Ur ett tekniskt och ekonomiskt perspektiv

In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.

Irreguljära immigranter - en idéanalys av den politiska debatten

Every human being has the right to the highest attainable standard of health. This is regulated by the UN in the Declaration of Human Rights. However, Swedish legislation discriminate the group of irregular immigrants, regarding the right to health care. Therefore, Paul Hunt, the UN's special rapporteur on the right to health, draws serious critique on Sweden which has caused extensive debate regarding the matter, both in the civil and political sphere of society.Thus, the aim of this essay is through an analysis of the political debate; make visible the norms of citizenship which are dominating the argumentation of the seven parties represented in the Swedish Parliament. An analytical framework, consisting of three dimensions, is therefore used in order to interpret the material which is relevant for the debate.The conclusion is that Moderaterna and Centerpartiet mainly base their arguments on communitarian values, while Kristdemokraterna and Folkpartiet rather show influences of liberal ideas.

Översyn av uppvärmning

The heating of companies premises is today functional with electrical heating and heating offossil fuel. The energy cost for these kinds of heating in buildings has heavily increased duringthe last years and the influence on the environment has become more visual. This leads to thatenterprises today become more anxious to render energy more effective and find alternativesolutions to their ancient heating systems. This is something that Skandinaviska kraftprodukterAB in Halmstad has become aware of.The purpose with this examination is to find the most cost-efficient and environmental measuresfor the office and workshop premises of SKP AB. Where one of the bigger things is to find agood alternative for their current oil furnace, which was heating the workshop.

This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

Identifiering av merva?rden i EPC-projekt

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
