Energieffektivisering av Åhlénshuset i Umeå : Utredning av åtgärder för ventilation, värme och kyla

Sweden is a country that has made some progress in developing energy efficient solutions. The problem in Sweden is that many houses and apartment buildings are old and have inefficient ventilation- and heating systems. This energy is lost when systems are inefficient, which then results in huge economic costs. Luckily, more and more people are becoming aware of this, which means that Sweden is on track to become even better within energy efficiency.Energy use for the housing- and service sector amounts to 166 TWh of total use at 616 TWh. Without distribution and conversion losses, these figures show that the housing- and service sector accounts for almost 40 % of the country's total energy consumption.

Anglosaxarna och Brittanien : Kulturell Identitet hos ett Migrerande Folk

Many questions are still left unanswered regarding the period c. 450-700 AD, when hordes of Anglo-Saxon migrants landed on the British Isles and by doing so made the starting point in the foundation of England. Who were these Germanic tribes? The theories of how the migration proceeded are today many. The two major theories today concerns whether it was a question of a mass migration or a gradual migration proceeded by smaller groups of military elite.

BIM för Hållbart Byggande

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

Organizing for value creation : a corporate perspective on urban farming

In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.

Bearbetning av befintligt bostadsprojekt med syfte att uppnå passivhusstandard

I detta examensarbete har energiberäkningar och analyser enligt FEBY12 gjorts på ett radhusområde för att undersöka vad som krävs för att lågenergihusen ska uppnå passivhusstandard. Att uppföra energisnåla byggnader är i dagens samhälle viktigt för alla företag eftersom människor blir allt mer energimedveten och krav från beställare blir allt högre. I arbetet har en modell av radhusområdet modellerats i Revit Architecture för att på ett smidigt sätt få korrekta värden i de olika energiberäkningsprogrammen Vasari, Energihuskalkyl och PHPP. Programmen har helt olika kvalitéer därför har en jämförelse och analys av programmen utförts. Analyser har tydligt visat att det krav som finns för att uppnå passivhusstandard på värmeförlusttalet är betydligt svårare att uppnå än det krav som ställs på den levererade energin. För att uppnå passivhusstandard vidtogs diverse åtgärder såsom U-värde för väggar förbättrades, ventilationsaggregatets verkningsgrad höjdes samt fönsterpartierna reducerades avsevärt.  .

Framtidens elbilar utmanar nutidens elnät : Påverkan av ett ökat antal elbilar på ett halländskt elnät

The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years.

Början på en dag som annars aldrig börjar : Om Fontänhusets betydelse för dess medlemmar

This study was made to examine what the Fountain house can do to help their members and how the members feel about their situation and their ability to participate in their rehabilitation. To do so we contacted one of the Fountain houses in Sweden, located in Falkenberg, to get a better view of what their members thought about the process. Our main purpose with this study was to turn the spotlight on what the Fountain house organization means to its members. To do so we had two main questions that we wanted to examine more closely:?How do the members experience the Fountain house organization? ? To which extend do the members feel that they are allowed to participate in their rehabilitation? ? How much influence do the members feel that they have? For this study we choose to use the qualitative method which included a lot of literature research, observations and interviews with members of the Fountain house organization.

Beräkning av energianvändning i svenska småhus

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.

Krav, kontroll och det sociala stödets roll: En kvalitativ studie om hemtjänstanställdas upplevelse av sin arbetssituation

Syftet med detta examensarbete är att undersöka upplevelsen av arbetsförhållanden för kommunalt hemtjänstanställda. Intervjuer har utförts med tio hemtjänstanställda inom kommunal hemtjänst. De övergripande frågorna rör arbetskrav, kontroll, och socialt stöd. Arbetsstressmodeller som, krav-kontroll modellen (Karasek & Theorell, 1990) och Houses typer av socialt stöd (Cooper, Dewe, & O`Driscoll, 2001) har använts vid dataanalysen. Resultaten visar att de hemtjänstanställda upplevde ett bra instrumentellt och informativt stöd från arbetskamrater.

Längs en och samma grusväg. En studie om författarna till några handskrivna sångböcker från sekelskiftet 1900.

Title: Along one and the same road - a study of the people behind some hand written song books from around the turn of the 19th century. It is based on some hand written songbooks found in homes along the small byroad in Kruse, Alva, Gotland. My own connection to the place is that I was born in one of these houses. During the summer of 2008 interviews were made with four people who live or have lived along this road themselves. Some of them have even lived in the same houses as the owners of the books.

Miljöpolitik eller personlig frihet? : fallstudie av Växjö Kommun

This thesis is a case-study of an ongoing court case between the Swedish Competition Agency and Växjö Municipality about a set-up requirement to the long-distance heating system for newly built private houses on municipality owned land. This requirement was set up as part of the municipality?s long-term environmental goals; however the Competition Agency claims that the demand is damaging the free market in the municipality. The purpose of this thesis is to determine which normative assumptions the decision makers have based their actions and re-action on, and whether or not these assumptions are valid, thru theoretical ideal types. This is determined via method of textual analysis.

Erosionsskydd i strandzoner :

Erosion in coastal areas is a common problem all around the world. The range of the problem depends on several factors, i.e. type of bed-rock and soil, wind and wave climate. Another factor is whether the area is of high interest, i.e. if the area is important for tourism and recreation, if there are houses and other buildings close to the shoreline or if it is a site of special scientific interest.

Kyrkorestaurering ? problematiken kring kulturhistoriska värden

This thesis handles the problems regarding different value aspects which are applied during restoration and renovation of churches. The curator?s aspects along with the interests regarding change that exists today, is often integrated and is therefore affecting the final results. The thesis aims to discuss the different perspectives and to look at the different values the room possesses. Furthermore, the historical aspects are discussed along with possible strategies to increase a positive outcome of restorations and how to integrate churches to the modern standards in terms of use and allowing them to be a part of a living cultural heritage.Church buildings have historically speaking always had a significant meaning to people, independent of religious belief.

Ombyggnation av gymnasieskola i stockholmsförort : Omvandling av gymnasieskola från 70-talet till framtida skol- och fritidscentrum.

The aim of the report is to develop a new design proposal for an existingsenior high school building in Skärholmens Center, Stockholm. Theschoolhouse is a result of the extensive residential project during theperiod between the years 1965-75 in our large cities peripheral and holdsanonymousand "gray face" that has characterized many houses from thesame era. Over the years, the number of students steadily declined andthe reason lies partly in the school's physical environment which cancertainly be regarded as substandard. This despite the fact that it islocated right next to Sweden´s largest trading block. A thorough analysisof the school building and the ambient area has been made incombination with a continuous dialogue with students and staff at theschool.

Uttorkning av lera : Orsaker och följder

When building a house or similar the stress on the ground increases and deformations can arise. The deformations create a foundation that the building is not constructed for and damages on the building arise. The increased stress on the ground can be derived back to the building, but it is possible that the increased stress may well derive from different sources such as other buildings or trees.       The building is an older property, built in the late 19th century alternatively early 20th century, and is today used for rental housing and has suffered severe damages due to subsidence. The goal of the thesis is to find possible causes for these subsidences. The thesis was executed as a combination between literature- and casestudie. After careful studies it has been found that a probable cause for these subsidences is trees. Through field- and lab studies it has been found that the trees has effected the ground through there accumulation of water.
