Designoptimering, Energi och inomhusmiljösimuleringar i en integrerad BIM-projektering / Designoptimiation, Energy and indoor simulations in an integrated design work

Syftet med en integrerad projekteringsprocess är att information tidigt skall tas fram och att projektörer skall kunna arbeta parallellt, exempelvis genom en gemensam BIM-modell. Revit och IDA Indoor climate an energy, även kallat IDA ICE, har i denna rapport visat sig vara två mycket effektiva verktyg som tillåter att information både kan tas fram, i form av energianalyser, men även kommuniceras digitalt med hjälp av så kallade IFC-exporter. Då projektörer får möjlighet att jobba i en gemensam modell kan de arbeta parallellt vilket innebär att information kan tillföras både tidigare och snabbare i projekteringsprocessen. I Revit kan arkitekten enkelt skapa olika utformningsförslag och jämföra dessa med avseende på energianvändning. Analyser från denna studie har visat att energisimuleringar i Revit kan användas för att utforska olika utformningsalternativ och därmed finna optimeringsmöjligheter med avseende på energi och inomhusmiljö.

Fuktomlagringar i välisolerade ytterväggar : En undersökning för att fastställa en rimlig inbyggnadsfuktkvoti träreglar med fuktsimuleringsprogrammet Wufi 2D

To save energy it?s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more moisture to dry. More moisture in combination with higher relative humidity may pose a higher risk of microbial growth.

Effektivisering av mellanspänningsnät med enkla medel : Feldetektorer och sommardriftläge

Renewable energy and the charging of electrical vehicles will increase in the future. Therefore the risk of outages is also increasing, partly because renewable energy is intermittent and the production amount can change fast. Charging electrical vehicles is often demanding high effect in short time, which could make faults occur. It takes more advanced technology to short the outage time. Today Övik Energi has high reliability in the power grid, but in order to maintain the reliability, it is time to prevent problems that can occur in the future. This thesis has presented a suggestion for the placement of fault detectors Protrol IPS2, in which a total of four detectors is proposed.

Foderbetor och kogödsel som substrat för biogasproduktion; anaerob mesofil samrötning i labbskala

One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.

Undersökning av processparametrar för optimering av sol-gelprocessen för produktion av kärnbränsle

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Myndighetsutövning ur ett miljöperspektiv : En studie på miljömässigt ansvarstagande på Vuxenförvaltningen på Eskilstuna Kommun

Under lågkonjunkturer är det ofta ungdomar som drabbas hårdast på arbetsmarknaden. Ungdomsarbetslösheten i den Europeiska unionen har i och med den senaste finanskrisen ökat dramatiskt och genomsnittet ligger på en nivå över 22 %. Det land som 2011 hade den högst rapporterade ungdomsarbetslösheten bland medlemsstaterna var Spanien, 46,4%, och den lägsta återfanns i Nederländerna med 7,6 %, dessa siffror har fram till mätningar i mars 2012 växt till 51,1% för Spanien och 9,3 % för Nederländerna. Denna uppsats ämnar att utifrån teorier kring utbildningssystem, arbetslöshet och dual marknadsteori jämföra varför stora skillnader i ungdomsarbetslöshet existerar mellan dessa två länder.Genom en deskriptiv studie av de båda ländernas utbildningssystem, arbetsmarknader och arbetsmarknadsåtgärder finner vi stora skillnader mellan länderna, som till viss del kan förklara varför Spaniens ungdomsarbetslöshet är mer än fem gånger så stor som Nederländernas. Vi fann skillnader mellan de båda ländernas utbildningssystem och vilka åtgärdsprogram som införts för att reducera ungdomsarbetslösheten samt att länderna drabbats olika svårt av den senaste recessionen..

Att vilja men inte kunna. Böcker och bibliotek i Filippinerna.

The history of books and libraries in the Philippines starts after the arrival of the Spaniards in 1521. During the Spanish era, most of the libraries were established through the religious orders to support their own religious mission. The Americans came in the beginning of the 20th century and have had a decisive influence on the education system and the development of libraries in the Philippines. For the analysis, I have used the models of Michael H. Harris and Magnus Torstensson in their studies of library development.

En bild säger mer än klara ord : En undersökning av visuella och narrativa komponenter i myndighetstext

According to law all Swedish authorities must express themselves using correct, plain and comprehensible language whenever they communicate with the citizens in order to make it easy to understand what needs to be known to participate in the Swedish democratic society. I would like to explore if there are more tools than the language that could be used to make their communication easier to comprehend, in this case images and stories. In this essay I will investigate the relationship between the written words and the visual components ? images and illustrations ? in brochures from Swedish authorities. I will also try to identify possible narratives in the brochures, and examine the functions of these narratives.

Mobiltelefon utformad med EcoDesign

The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.

What opportunities and obstacles center managers feel that they have in the rehabilitation process and their expertise in rehabilitation are adequate. The essay is based on qualitative, in which six interviews were conducted to help capture the Heads of Unit subjective experiences. Five of the respondents are heads of units in the elderly, and an interview with the rehabilitation coordinator of the municipality. Respondents' comments and relevant literature form the basis for this essay.

Historielärobokens användning : En studie om gymnasielärares användning av historieläroboken.

The aim of this thesis is to examine how secondary teachers in the subject of history are using the textbook in their teaching. Four questions are being dealt with in this thesis. What importance is being placed on the use of history textbooks by the secondary teachers? What priorities do the secondary teachers have? How do they deal with student interests? And what is the importance of the secondary teachers? work experience? I have interviewed four secondary teachers with different work experience to complete this thesis. A Dictaphone has been used in all the interviews. Research has shown that textbooks now have a central role in teaching and the lack of alternative materials and reduction of teaching hours has made it difficult to replace. The main conclusions of the thesis are that the history textbook has a dual role depending on the teacher you ask, and that the history book is used differently by the teachers.

Påverkan av skuggor från vindkraftverk

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Framtidens driftcentral : En analys av den framtida driften av ett svenskt elna?t

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.
