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.

Inkludering - Utopi eller verklighet?

The aim of this paper is to shed some light on to what extent the process of making reality of Inclusion, as stated in International Declarations and in Government policies, has reached the actual educational activities in the school system. My chosen method is a case study, in which I have combined a survey with interviews in order to retrieve enough data for my analysis. I have also studied a number of policy documents and relevant literature. My analysis concludes, for the school that I have chosen to study, that there is still a lot to be done before inclusion becomes a reality. There are many obstacles to overcome, for instance; a constant struggle to obtain enough resources and to reach relevant levels of competence within the personnel.

Det sociala området i EU, sett genom dokumenttexterna Romfördraget, Lissabonstrategin, den socialpolitiska agendan och Sveriges strategirapport.

The social dimension in the EU, explored through the document texts of the Treaty of Rome, the Lisbon Strategy, the Social Policy Agenda and the Swedish Strategy ReportThis paper explores the social dimension of EU social policy, except the aspects of the economic and labour market. The EU documents reveal an underlying line of thought stemming from the alignment of the six founding countries, spearheaded by France, with the conservative corporatist welfare model. As one of four European welfare models, the conservative corporatist model emphasises labour market issues, corporate social responsibility and the subsidiarity principle in EU social policy. It also influences how the texts define the terms social, social policy and social exclusion. The definitions determine how policymakers combat problems such as social exclusion and identify the policy issues to be included in EU social policy.The Swedish Strategy shows how the country is responding to the objectives that it has been assigned by the EU and how it plans to attain them.

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.

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.

Kvalitetsförändringar hos rajsvingelsorterna Hykor, Perun och Paulita under första skörd :

Today, high-yielding leys of good quality are a must for Swedish dairy and beef enterprises if they are to become profitable. Thus, it is of interest to evaluate the quality of the recently released high-yielding Festulolium hybrids ((Festulolium braunii (K.Rich.) A.Camus). The aim of this project was to determine at what phenological stage three different Festulolium hybrids should be cut in order to get the highest nutritional value. The hybrids studied were Hykor, Perun and Paulita. In the study I also investigated if leaf proportion of the crop could be useful for predictions of the crop content of metabolizable energy. The cultivars were grown in plots within a variety trial with ryegrasses.
