Varför uppförs så få bostadsrätter med passivhusstandard i Sverige? : En fallstudie mellan ett passivhus- och en konventionell fastighet
Abstract Background: In 1997 the Kyoto Protocol was signed, it?s an international agreement which is aimed to reduce greenhouse gas emissions. Sweden's goal is to reduce energy using in buildings with 20 percent by 2020 and 50 percent by 2050. This is a comparison with levels from 1995 (Glad, 2006). For Sweden to be able to reach its goals, they need to construct more low-energy buildings (Åhman, Wahlström & Lundblad, 2010).
Pivot - en aktiv sittmöbel för kontorsmiljö
The purpose of this project was to invite a changed perception of active sitting, to introduce a more active way of sitting in office environments and destigmatize an active sitting posture such as straddling by giving active sitting products conscious aesthetics based on environment and positive associations. The goal with this project was an active sitting product for office environments with aesthetics considered encouraging to movement in a relaxed way, regardless of age and gender, and connect to materials and aesthetics related to activity, experience and recreation. Horseback riding, retro style surfing and skateboarding was an entry of investigation. The project was based on existing active sitting products, their function and production techniques. It was not a part of the project to investigate new models of sitting.
Stomme i småhus ! : - En teoretisk studie av olika bärande vägglösningar !
This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.
Öjingsvallen vid sjön Öjingen : en pollenanalytisk studie av en fäbodvall i Ängersjö, Hälsingland
By using pollen analysis and 14C-dating, the history of vegetation and land use at the old shieling place (Sw: fäbodställe) Öjingsvallen in Ängersjö parish, central Sweden, was studied. The aim of the study was to answer the following questions:
1) When was Öjingsvallen established as a shieling place?
2) What was the land use at Öjingsvallen?
3) Was the use of Öjingsvallen as a shieling place affected by the agricultural crisis in the 14th and 15th centuries?
4) Is there any relation between the establishment and land use of Öjingsvallen as a shieling place and the historically known increase in the number of shieling sites known to have taken place in the 16th and 17th centuries?
5) Was the use of Öjingsvallen as a shieling place affected by the iron production in the area?
According to the study, Öjingsvallen was probably established as a shieling place during the period A.D. 300-700. The main land use at this time was forest grazing.
Portföljoptimering som alternativ till indexfonder : Hur skulle en fond konstruerad enligt portföljoptimeringsmodeller utvecklas i jämförelse med index?
This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.
Shareadox : -The paradox of service quality assurance in Sharing Economy businesses
The purpose of the Sharing Economy is to exploit unused resources between people, as an alternative to buying new and owning themselves (Gansky, 2010). Gansky (2010) argues that a major reason why the Sharing Economy has grown in recent times is, besides from the recession and people?s increased environmental awareness, the urbanization which has made people move closer to each other and in to the big cities. This in addition to an increased use of GPS technology in smartphones enables people to be constantly connected to an ever-changing network. People now share and exchange services and products from each other.
En plats att bo på? : hyresnivåernas nivåfluktuationer 1999 - 2007
The purpose of this paper is to present and analyze the yearly expenses for Swedish rental apartments during the period 1999 to 2007. At the end, it will give the reader a general picture of how the cost-level has fluctuated depending on the production year when the apartment building was finished, and where the same building is located. This paper has the following questions as a starting point:- Can there be an identification of regions depending on where people tend to favor renting an apartment?- How are those regions distributed? That is, where are the cost-levels of the yearly rental expenses highest and where are the levels lowest?Nine statistical surveys from the Swedish government agency Statistics Sweden (Statistiska Centralbyrån) have been used as primary sources for this paper. These surveys deal with price pictures of housing in general, but for this paper the only information that has been used is the one about rental apartments.
Stockholms blodbad i historieboken: En l?romedelsanalys under perioden 1869 - 1996
This thesis explores in which ways the portrayal of the event known as the Stockholm bloodbath has changed during the period 1869-1996. This is done through textbook analysis. In Sweden, history has been a school subject since the 17th century, and has throughout its history had a formative role in the Swedish school system. In the middle of the 19th century it was specifically stated that the aim was to help students nurture a sense of national pride and love of country. The aim of the study is to investigate how nationally loaded events have been portrayed in text books, as well as if and how the evolution of said textbooks reflect the evolution of the history subject as a whole.
Anläggningsmodellering i AutoCAD Civil 3D
SammanfattningExamensarbetets syfte är att ge en övergripande bild om vad BIM egentligen är och hur arbetsmetoden ska kunna påverka byggprocessen positivt. Rapporten fokuserar på anläggningsbranschen och då främst från en projektörs perspektiv. Ett projekteringsexempel visar även på hur en anläggningsmodell kan skapas med hjälp av en programvara som stödjer arbetsflöden i BIM.BIM kan utläsas Building Information Model och avser då den eller de modeller som utgör en digital objektbaserad representation av en byggnad eller en anläggning. BIM kan även utläsas Building Information Modeling och avser då ett arbetssätt, d.v.s. processen att skapa och använda en eller flera byggnadsinformationsmodeller i bygg- eller anläggningsprocessen.Det finns många fördelar med att använda BIM, inte bara i husbyggnad utan även i anläggningsbranschen.
BIM i förvaltningsskedet
Syftet med den här studien är att förbättra informationsflödet från projektering och produktion in i förvaltningen. Detta för att väcka ett intresse hos förvaltare och för att visa att det finns pengar att spara genom att ta hand om informationen från projekteringen och produktionen.Tidigare studier inom området BIM visar att stor fokus läggs på projektering och produktion men det är ett väldigt litet fokus på förvaltningen när man talar om BIM.Målet är att konkret kunna visa vad informationen är värd och att visa vilken information förvaltare använder och var den finns i byggprocessens skeden före förvaltningen.Rapporten bygger på en litteraturstudie, intervjuer och beräkningar. Förvaltare har blivit tillfrågade vilken information de använder i förvaltningen och sedan har projektör och entreprenör blivit tillfrågad ifall denna information finns att tillgå i projekteringen och produktionen. Värderingen av informationen har sedan gått till på två sätt. Det ena sättet är att bedöma kostnaden av att uppdatera information mot kostnaden att ta fram information på nytt.

Aim
The aim of this essay is to problematize how students with special needs are represented in the quality assurance documents of the school. The writer intends to point out how the ways in which the language used to describe students informs governing processes.
Effekten av Valutarisk på Bilateral Handel
This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.
Energieffektiva värmesystem : Lösningen till att nå energimålen i byggbranschen?
Sweden has an environmental goal to achieve until the year 2020. To achieve this goal the construction business has to take an initiative to use the modern techniques that are available to lower the energy consumption I buildings. There?s also a debate going on today regarding the energy demands set by the Swedish government through Boverket, some communities throughout Sweden thinks that the demands are to low and have therefore set up own demands regarding energy in buildings.The possibility to construct energy-saving buildings is today very great, with energy-efficient heating-systems and dense climate envelope. The interest to raise energy-efficient buildings have also increased as a consequence that the population have become more aware about their impact on the environment.
Äldreboendet på Zakrisdal : En studie om solvärme med säsongslagring
A home for elderly is planed to be built at Zakrisdal, Karlstad, Sweden. The heat source for the building was at the time not determined. In order by the local government of Karlstad this report is meant to examine if the need of heat could be provided only by solar heat combined with a seasonal heat storage. The problem to solve is, if the need of heat from the home for elderly is provided from only solar heat, whitch dimensions of the solar collectors and the storage is needed?.
