In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.

This account deals with my degree in furniture design. The project was done in collaboration with the architect firm Byggnadskonst AB in a quest for the cafe chain "Vivels"Byggnadskonst AB?s mission was to make the interior of the cafe that Vivels is building in Larsberg Center on Lidingö. My assignment was to design chairs for the café. In the beginning I had even thought about designing a table, but as time past I focussed more and more on the chairs.

Purpose: The purpose of this study is to investigate possible links between short selling and the stock market movements using econometric test models. Methodology: A quantitative study carried out on the time series stock lending and OMX Stockholm 30 index. Information is gathered through qualitative interviews with specialists in the field of stock lending, and studies of relevant newspaper articles and reports. Theoretical approach: The theoretical frame of reference is a further consideration of supply and demand theory. The empirical study is implemented by the simple linear regression model and a vector autoregressive model (VAR).

This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

The interest in building low energy houses has increased along with the rising engagement inthe climate questions. With the advancing energy prices it is highly suitably for those whobuild and administer their buildings in long-term to build energy-saving houses. 40 % ofSweden?s total energy consumption constitutes of the energy in residences, therefore it iscrucial to take advantage of all the free energy as we possibly can. With crucial questions likequality of living and profit low energy building is a subject that concerns us all.Three proposals for apartment blocks are presented in this work on a real estate in Stockholm.Each proposal is developed through unique processes of design with the purpose to displaypossibilities to deal with the energy requirements of today and tomorrow through energybased architecture.The first proposal is an apartment block based on a traditional design process, the demands ofthe property owner and it?s affected by opinions from architects.

At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

During the 1990?s a large number of building projects were revealed where lack of moistsafety precautions during the construction process had led to extensive moisture damage. Alsoresent implemented studies have shown that the problems with moisture damages have ratherincreased than decreased during the past few years. Moist is considered to be one of the mainfactors to cause unhealth due to deficiencies in the indoor-environment and does also causeunnecessary expenses and a reduction of the confidence in the construction industry.In this Bachelor of Science thesis three projects have been reviewed to examine how moistsafetyhas been observed during the construction process. Main focus has been to identify thebuilding components that are the most exposed to moist, and to examine how they have beentaken into account during the period of design and construction.

AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.

Målet med detta arbete var att belysa skillnaderna mellan ett fyravåningshus med trä- respektive halvprefabricerad betongstomme ur ett tekniskt perspektiv för att utröna vilket stomalternativ som är att föredra.Faktorer som belystes var:Tjocklekar på bärverksdelarLängsta möjliga spännvidderInstallationsmonteringElementmonteringGrundstorlekLjudisolerande förmågaRisk för fuktskadorBranddimensioneringProjekteringskomplexitetBygghandlingar från ett befintligt flerbostadshus med trästomme erhölls och analyserades, och ett hus med likvärdig stomme av betong projekterades.Bärverket med halvprefabricerad betong dimensionerades efter rådande Eurokoder och detaljer utformades enligt gällande lagar och regler samt erkänd branschstandard.Ur de tekniska perspektiv som avhandlats i denna rapport väger fördelarna med betong något tyngre än träalternativets fördelar trots att egenskaperna i vissa hänseenden är mycket lika.Betongalternativet ger stora fördelar vad gäller brand och ljud och är samtidigt enklare att projektera, medan trä har sina fördelar i montering och grundläggning. Att välja en stomme av trä till ett flerbostadshus verkar också ha fördelar i de icke avhandlade aspekterna, t.ex. miljö och arbetsmiljö.För att uppfylla ljud-, brand- och fuktkrav i ett trähus krävs det avancerade byggsystem som innebär stor komplexitet i projekteringen vilket kräver ett nära samarbete mellan träprojektör och fabrikör. .

This project is based on my fathers farm which lays outside Löberöd, twenty kilometres south of Eslöv in Skåne. While my family for some time have thought about building a new milkingstable with AMS(Automatic milking system) I decided to compare the AMS with a conventional milkingstable. We are abit concerned about how many cows we should have in the new stable. Because of that I calculated with two different number of cows. I have compared three different types of milking stables: One alternative is 180 cows milked in a double eigth hearing bone milking stable. The second alternative is 128 cows milked with two DeLaval VMS-robots. The third alternative is 171 cows milked with three DeLaval VMS-robots. One salesman from DeLaval and one salesman from A-betong helped me to get marketprices on the milkingrobots, building, ventilation and prices on all the concrete. In all the costs labour is included. The rest of the costs are calculated in a softwareprogram called K-data 03 which is a program with predicted costs. The calulations from the program showed that the price in the milkingpit system was 51 000 sek per cow.

During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.

The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building?s physical characteristics for reliable energy analysis.
