Förskolor med passivhusteknik : En utredning av passiva förskolor
As a result of directives from EU, with the ambition to reach environmetal goals, The German organisation Passivhaus Institut has defined a passive house. A passive house is a building that is very energy efficient and makes a small impact on the environment. The energy from the inhabitants as well as the appliances & fixtures in the building should equal the energy that is required to heat the building. A Swedish version of the passive house definition has been defined, taking into account the climate conditions and the difference in building regulations.This thesis is a request from Skanska on how it can improve and develop an ongoing passive house project, involving an infant school. The intention of this thesis is to identify difficulties & display potential development areas for infant schools.The method of research conducted is as follows: interviews of clients, ventilation consultant, consultant for heating system and an energy calculation consultant, an inspection of the infant shcool in process, investigation of completed infant schools and a study of relevant literature.From this research it was found that it is difficult for infant schools to pass the criteria for passive houses. The conclusion of this thesis provide several guidelines on how to improve the outcome of existing projects & the steps needed to be taken for future development in this area..
Koalitionsbildning och Fragmentering. En studie av koalitionsbildning i kommuner med fragmenterade partisystem
During the last decades the Swedish local party systems have gone through some considerable changes. The number of parties present in local party systems have increased and in some cases even doubled. This makes coalition building between parties complex and parties will be forced to rethink their coalition strategies and adjust to the new circumstances. Theoretically, coalition building has often been considered and applied to national data and there have been just a few attempts to develop and theoretically explain coalitions on a local level. Thus the aim of this paper is to use different theoretical approaches to local data to test the significance of traditional coalition theories.

Byggprocessen i förändring - Visionen om BIM
Det primära syftet med detta examensarbete kan sägas vara att skapa en uppfattning hos Skanska Väg & Anläggning Sydost, som är initiativtagare till detta examensarbete, om vad BIM (Building Information Model) är och hur det lättast kan implementeras i deras arbetsprocesser. Det skulle vara omöjligt att täcka in alla aspekter av BIM under den korta tid som funnits till förfogande och inom ramen för detta examensarbete, därför har de aspekter som ansetts vara viktiga för företaget samt författaren lyfts upp för utredning.För att kunna nå dit har examensarbetet till uppgift att kartlägga och synliggöra de skillnader som finns mellan dagens byggprocess och BIM (Building Information Model) och utifrån det föreslå möjliga sätt att implementera denna arbetsmetod hos Skanska Väg & Anläggning Sydost.I examensarbetets första kapitel ges en kort introduktion och bakgrund till hur byggprocessen förändrats under tidens gång. Ett syfte och en frågeställning formuleras och en avgränsning för examensarbetets omfattning görs.I examensarbetets andra kapitel ges den teoretiska bakgrunden till dagens byggprocess. Viktiga aspekter av dagens byggprocess lyfts fram och förklaras. Därefter följer en presentation av begreppet BIM och vad det innebär.
44 m2 extra - ett förslag på nytt fritidshus
My Finnish grandfather had a passion for architecture, eventhough he wasn?t an architect. In the end of the 1950s he builta wooden summerhouse on a lot outside of a small villagecalled Lempäälä, close to the city of Tampere. Today the lotbelongs to my mother. Every time I visit our summerhouse, itmakes me want to do as my grandfather did ? to build a smallhouse next to it.My project is a proposal for a wooden house on mymothers lot.
Klassificering och värdering av finansiella instrument : Ett tillförlitlighetsperspektiv
During the financial crisis voices were raised towards the regulatory framework IAS 39 recognition and measurement of financial instruments and pointed out that it was inadequate. The complexity of the framework contributed to the fact that it was difficult to apply. IASB accelerated the modeling of the new to be regulatory framework IFRS 9. In this study we will focus on the reliability of accounting information, which is an important aspect from the stakeholder?s point of view, for example, to be able to make the best decisions the accounting information should be proper.
Utvärdering av befintliga passivhus : En byggnadsfysikalisk bedömning och mätningar om temperatur, och fukt analys på ytterväggarna
Energy price are on the way up to a high level that will not diminish in the future make us to focus more on the sustainable development for a better solution of residential houses. Passive house or low energy housing are one of the solution to make residential more environment friendly, in same time it´s a financial security using less energy, and saving money. The last 10 years in Germany and all around Europe the concept of passive house been developed, and people aim to know more about these concept that leading the market more attractive for passive houses. A passive house is a well designed building highly insulated and air tight with mechanical ventilated system for the whole building envelope that minimizes the use of energy for heating [1].The housing company Mimer has chosen to invest in low energy consumption in every new housing project. These future plan projects are decided to use less than 75 kwh per square meter annually in purchased energy [2].This thesis is about new constructed passive houses, and focuses on the evaluations of the temperature, and moisture condition for attic, external walls and joist.

Gestaltningsmässigt har inga hinder funnits för eklektiska och anakronistiska influenser..
Frånluftsvärmepumpens möjligheter i flerbostadshus
If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.
Utvärdering av miljönytta för olika miljöcertifieringssystem för byggnader : En jämförande fallstudie på Swecos kontor i Stockholm, Göteborg och Malmö
This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.
Utvärdering av den bärande tegel- och betongstommen i en byggnad från år 1916
This Master thesis is about a postal- and telegraphic building in Eskilstuna, Sweden. The construction methods for the specific building and buildings in general from the same time are described. The purpose of the report is to describe the loads acting on the building and how it has been built and why it has been rebuilt during the years. After this, possibilities of reconstruction and adaptation for today?s demands can be evaluated.
Informationssökning i elektroniska informationskällor Valmöjligheternas vånda
The purpose of this thesis is to examine which factors influence librarians selection of electronic information sources, and to investigate whether librarians use of search strategies and search tactics changes depending on which information source they use. The electronic information sources are: online databases, Online Public Access Catalogues OPAC, World Wide Web, and CD-ROM databases. The theoretical framework is based on step 3 Select a source and step 4 Formulate a Query in Marchioninis information seeking model. The search strategies are divided into two categories: analytical and browsing strategies. In order to supplement the theoretical framework with empirical facts, 8 librarians were interviewed.

Det norska energideklarationssystemets konsekvenser för äldre byggnaders karaktärsbärande värden
Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.
Strukturering av besiktingsfeloch information : En undersökning av besiktningsbilagor
Inspection errors are nowadays usually written with pen and paper during building inspections. A company in Stockholm is developing a method by which inspections are made digitally from the beginning and where the inspection attachments shall be stored in a database. The idea of this method is that entrepreneurs can use the database to get an experience feedback from previous surveys so that they can improve their production processes. One problem that occurs is how inspection errors will be sorted into the database. They have to be sorted so that contractors or clients can use and sort out the information in a sensible way when they want to evaluate and make improvements in their production processes.This thesis examines how the inspection errors can be sorted in a structured manner.
