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).

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.

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.

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.

Den 1 januari 2005, startades det europeiska handelssystemet med utsläppsrätter. Handelssystemet avser att minskakoldioxidutsläppen inom Europa, för att fullfölja åtagandet i Kyotoprotokollet. I Sverige har flera sektorer påverkatsav handeln med utsläppsrätter bl.a. energisektorn, som står i fokus för denna studie.Syftet med uppsatsen är att studera hur de större och mindre energibolagen samt de ansvariga myndigheterna iSverige uppfattar systemet för handel med utsläppsrätter. För att uppfylla syftet formulerades ett antalfrågeställningar om hur energibolagen och myndigheterna ser på handelssystemets följande områden, fördelar ochnackdelar, implementering, tilldelningsprinciper, förbättringspotential, framtida utveckling, samt om det finns någralikheter och skillnader mellan energibolagen.

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.

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.

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?.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

Projektet grundar sig i grannarnas motvilja till en kontroversiell byggnation vid Högalidsparken. Parker är som regel inte bebyggda och bebyggelse med bostadskaraktär minskar parkens offentlighet. Detta förslag bidrar med att utöka parkens yta och genom att hålla bygghöjden låg, fortfarande bibehålla grannarnas utsikt över parken. I Stockholm råder också brist på utrymmen där flyktig eller säsongsbetonad handel kan ske innomhus, därför innehåller förslaget även en marknad inriktad främst till privatpersoner och små företag..

In the year 2002 the European Union decided on a new directive according to the energy use in buildings. The outcome of this direction is a proposition from the Swedish government on the outlines of a new law in the field of energy use in buildings. The date that the law will be applied is the first of October 2006. In the future al real estate owners must be able to show an energystatement over the real estate. This project contains cooperation with HFAB a local real estate company where two buildings are analyzed according to their energystatement.

This work has been done to develop a plan for a future dairy barn at theGästgivaregården and to show the space needed for cows and replacement heifers. Itwould also show the storage that will be needed. The design was largely based on resultsfrom studies on six different farms, but also the facts that are taken from research papersand articles in order to compare theory with practice. Because some farms only whereinterviewed by phone I have used a query form to obtain comparable resultes.The aim is to build a new barn with Automatic milking. I've drawn a milking stable for120 milking cow and replacement heifers with the capability to house up to 140 milkingcows if the farm would expand in the future.Calculations of feed amounts and space requirements have been made to see how manyhectares are needed to supply the cows and replacement heifers with feed and to knowabout what size of storage space is required.The investigations made in this writing are to answer questions about the AMS-unit`sposition and how to best maintain a good health status in the herd.

We came in contact with the project "Grönplan Danderyd" that aims to create a green structure plan for a municipality of Stockholm called Danderyds kommun. Our thesis is a part of this project and makes it's contribution through the gathering and systematization of the knowledge of the functions of an urban green structure. It also makes a contribution through suggesting how this knowledge can be applied during the construction of an urban green structure plan. We found that "Stadens parker och natur", published by the Swedish National board of Housing, Building and Planning, was a recurrent source of information in the green structure plans that we studied. We saw a need of complementary additions and updates to the rather old report and found literature that adds the developments of the last decade. First of all we have chosen to make themes based on the functions of a green structure that were presented by 'Stadens parker och natur'. The themes we suggest that a greenplanning document manage are: Recreation, Pedagogies and Heath, Biological Diversity, Green structure in the History of Building Cities, Cultural Identity, the Health of the City, Biological Technology in the Municipality and Use and the Users. We found good examples of how to handle these themes in documents that handle greenstructure planning from the municipalities of Göteborg, Strängnäs, Eskilstuna, Malmö, Lund, Västerås and Uppsala.
