This study examines the use of building modeling and energy simulations in the design process  of  a  building.  The  take-off  point  is  the  notion  of  energy  simulations  being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines,  such  as  the  architect  and  the  energy  specialist,  would  create  smoother workflows, which would reduce this cost and open up for more frequent and iterative energy  simulation  processes.  The  study  is  an  assessment  of  the  modeling  tool  Revit and  the  simulation  tool  Virtual  Environment  and  whether  they  can  create  smoother workflows, and make leeway for a more frequent use of energy simulations throughout the  design  process.  It  also  investigates  the  limitations  of  what  can  be  examined  by simulations in Virtual Environment. This will hopefully help clarify the future role of energy  simulations  in  design  processes.  The  method  is  a  trial  by  error  approach  of testing the two software tools by building and simulating a model. The results of these tests  show  that  the  workflow  is  not  optimal  (and  therefore  time  consuming)  for frequent  and  iterative simulations  throughout the  design  process,  but  it  also  reveals some  great  possibilities  of  what  can  be  performed  with  these  two  powerful  tools  at hand.  Further  development  with  regards  on  platform  independency  of  the  building information  model,  including  seamless  exporting  and  importing,  seems  necessary  to strengthen the future role of energy simulations..

Demens är en folksjukdom som ökar och är vanligare idag än för 30 år sedan. Orsaken till detta är att människan lever längre och risken för att drabbas av demens ökar med stigande ålder. Personer med demens har begränsad förmåga att tolka samt förstå omgivningen de vistas i, därför är det viktigt att den fysiska inomhus miljön inte utgör ett hinder för personerna. Inomhusmiljön skall anpassas efter deras behov för att de skall känna trygghet och därmed påvisa positiv beteende. Syftet med denna litteraturstudie är var förkovra oss om hur inomhusmiljön påverkar personer med demens på vårdboende.

The aim of this Master thesis is to study how management, teachers and librarians at the university college Swedish school of sport and health sciences (GIH) view information literacy (IL) as a standard in higher education. I have used a sociocultural theoretical perspective, as the focus being on co-operation within the institutional context. The following questions are focused on: Of what importance are the control documents concerning IL as a standard in the educational program? How do the respondents view the value of, and the responsibility for, IL as a standard in the educational program? What are the conditions for co-operation at GIH to reach the standards of the higher education act? The methodology used is qualitative case study. Six qualitative interviews were carried out in order to describe the attitudes of the management, teachers and librarians related to this subject.

Fönster blir idag en allt viktigare del av en byggnads klimatskärm. Det ställs därför krav på olika funktioner vilka måste uppfyllas oberoende av fönstertyp. Då glas blir vanligare i moderna konstruktioner ställs det högre krav på värmeisolerande förmåga. Cirka 35 % av en byggnads värmeförluster sker genom fönster. Detta ställer krav på tillämpning av energieffektiva fönster vid ny- och ombyggnad. Underhåll av fönsterkonstruktionerna är en oundviklig detalj och måste ske någon gång under en byggnads livslängd.

The aim of this master?s thesis is to examine the accessibility for persons with disabilities to service, materials, and the library building in one Swedish public library, and also to see what guides the development of accessibility at this library. In order to do this we have studied guidelines and political documents to se how this library responds to them. To our case study, data have also been collected by qualitative interviews, and observation of what this library offers impaired persons at the library?s web site, in special materials, facilities, and the functionality of the library building.

Orust Kretsloppsakademi is a nonprofit organisation, with a goal of annually generate the same amount of electrical energy that is consumed. Orust is an island on the west coast of Sweden, north of Gothenburg. The population of 15 000 reaches 40 000 during summer, due to the large amount of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid.The conclusion is that the restraints for development of power generation from wind, solar and wave generation, are the power systems capability to transfer power, primarily in the transformers of the grid.

Studien är en kvalitativ undersökning som bygger på guidade rundvandringar och intervjuer med sex pedagoger från tre olika förskolor, både på småbarnsavdelningar och på syskonavdelningar. Syftet med studien var att undersöka vilken betydelse pedagoger tillmäter inomhusmiljöns utformning i förskolan med avseende på barns tillgångar till material och aktiviteter för sin utveckling och sitt lärande. Kunskapsöversikten redogör för ett historiskt perspektiv om hur förskolans inomhusmiljö har utvecklats och exempel ges på pedagogiska influenser som förskolorna kan ta idéer ifrån. Den belyser även miljöaspekten utifrån olika styrdokument och litteratur. Resultatet visar på att förskolornas inomhusmiljö har en fast objektiv miljö som utformas utifrån de resurser som finns tillgängliga för att få den subjektiva miljön i verksamheten.

The purpose of this study was to examine how some children with reading problems experience and use libraries. The main problem was: How do dyslectic children experience and use libraries and how do they handle their reading difficulties when using libraries? The questions at issue were: 1. Do children with reading problems use libraries, and if so how? - in which purposes do they use libraries? - which materials and services do they use? - why dont some children use libraries? 2.

The most common method for identifying merchandise in the commerce is by barcodes. Symbian OS is an advanced operating system aimed at cell phones and the most commonly used in smart phones. Opportunities to a full range of new services are given through barcode recognition in a Symbian OS based device. Therefore the purpose of this degree project was to create an application which would contribute to a future solution aimed at shopping where the cell phone constitutes a reader of items? identification numbers.

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

The bicycle is an individual means of transport. Many people prefer to cycle over short distances and in congested areas rather than take travel by car or public transport. This is a study of the use of bicycle as an option for commuting to work. It is a comparison between three cities: Stockholm, Copenhagen and London. The comparison is focused on solutions that benefit commuter cyclist and performed by studying cycle policies and other related documents.

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.
