Redesign of an existing apartment block in Kv Preussen to passive house

Passive houses are a relatively new concept in Sweden and by that it is meant a house without a traditional heating system. The most acknowledged passive house project is the terrace houses in Lindås, Gothenburg, which we have used as a reference. This project concerns a square apartment block. So far, no square apartment block has been built as a passive house in Sweden.The common opinion in the construction industry is that it is not economical to build extremely energy efficient houses. With Peab as commissioner our task was to investigate if that is true, if regarding the construction of a multi storey house as a passive houseMidroc, now owned by Peab, constructed in the block of Preussen in Jönköping during 2004-2005 four houses, with 132 apartments distributed on seven floors.

Projektering av vindkraft i turbulensintensiva områden : med fallstudie för Wallenstams planerade park vid Skuggetorp

Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.

Hållbar utveckling i svensk planeringspraktik : en diskussion kring förtätning och andra ambitioner

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

Produktivitetsförbättringar : - förhöjning av produktiviteten vid mekanisk verkstad genom förkortade transportsträckor och standardiserad bearbetning

The aim of this project has been to raise the production efficiency of Daliff Precision Engineering through reduced transportation time and a more standardized manufacturing process. The problem has upraised because of a big and diversified product flora without any standard products and with just small batches ordered. The report also tries to show the work procedure with general analytical methods and be an example of how a similar problem can be resolved. The transportation time is being proposed to be reduced through a change in the layout of the factory. By moving a few manual machines, dispatch and burring to more efficient locations, the total transportation time will be reduced by 55 %.

Musikteori på gymnasiet : En studie om gymnasieelevers inställning till musikteori

The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.

New Business Model for District Heating Firms Stabilizing the National Energy System with a Future Variable Electricity Production

The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.

Flyktingpolitiska diskurser: en kritisk diskursanalys av två debatter

The central goal of this study was to compare statements of the minister of migration in power in 1994 with those of the minister of migration in 2006. The statements reflect two peaks of refugee immigration in connection to the war in former Yugoslavia and the present war in Iraq. The study analyses the statements in a critical discourse analysis framework. More specifically the aim was to find out if there were any discursive differences in these statements and how they might manifest themselves in society. The material was composed of 12 texts, 6 for each period originating from Swedish newspapers and from the ministers' public speeches.

Kvalitetsarbetet i Nacka : En fallstudie av kundvalsmodellen inom äldreomsorgen

This essay discusses the interaction between the authorities in Nacka municipality in Sweden and supervisors within the eldercare. In Nacka politicians have gradually started delegate responsibility for how care-giving for the elder should be done and focus instead on formulating economical objectives and overall rules. It is up to the approved supervisors of eldercare to deliver good care and quality. The method chosen to accomplish this is public choice. This method is a part of the big New Public Management (NPM) reform which have had a big impact on Swedish public sector since the 1980´s.

Det förstärkta laglottsskyddet : Vid generationsskifte

When a person of the older generation in a family owned company wish to transfer his ownership to a person in the younger generation this can be done through a succession of generation. Different methods can be used to proceed with such a matter, selling the company shares for a price below the market value is one example of this.When the owner transfers shares to a person in the younger generation, either as a gift or by selling them to a price below the market value, the provision in the 7th chapter 4 § ÄB can be applicable. This provision establish that; when a gift that has been given during the grantors lifetime and when the purpose of this gift is to be equivalent to a testament, the gift shall be returned to the receiver if this action confines with the direct heirs statutory portion.A gift is to be equivalent to a testament when the giver had the intention to arrange the succession when the gift was given away, and when this gift did not amount to any economical sacrifice for the giver. There are two situations which causes a gift to be equivalent to a testament. The first situation arises when the gift is given by the giver right before his death, on his deathbed so to speak.

Gynnar eller motverkar kommunerna kostnadseffektiv miljöstyrning : en studie av kommunala taxor och avgifter

Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals. The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.

Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua

Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.

Expansionsmaskiner istället för strypventiler - en effektivisering

In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.

Transportfo?rpackningar och marknadsfo?ring av frukt och gro?nt inom dagligvaruhandeln : en pilotstudie i Sverige och Tyskland

The logistic business Svenska Retursystem AB was founded by the Swedish retail sector in the year 2000, and their introduction of a grey plastic crate to the supply chain for perishable goods changed the situation for the swedish horticultural sector. The new system revealed several challenges to be tackled by all actors, from the small family firm to the bigger organisations. Whereas the initiative comes from the customer himself, from the horticultural sector ?s point of view, a refusal of the new packing is a hard decision to take. It is however interesting that a comparison between the two systems, shows in favour of the corrugated board boxes, not only concerning environmental aspects but also for economical and ergonomical reasons.

Gränser och passager : En analys av de curatoriska och konstnärliga subfälten

I have, with a point of departure in two case studies; the artist, curator and scientist Andreas Gedin and Maria Lind, curator and director of Tensta konsthall, contextualized with a couple of respondents; the freelance curator, writer and editor Power Ekroth and the freelance curator and artist Carl Michael von Hausswolff, conducted a field analysis on curatorial and artistic practices. I have applied key concepts in order to conduct the analysis.Furthermore, the case studies and the respondents have been placed in a contemporary artworld. These components have been related to a contemporary historical segment of the artworld. This in turn, has been related to older, international cicumstances of change and various conditions in the two subfields. I have suggested certain a proximity in the artistic and curatorial practices.

Vetenskaplig publicering i gungning

Scholarly publishing has since the introduction of electronically distributed periodicals seen a time of change, mainly in the STM-business (Science Technology and Medicine). The roles of the three main participants in the publication process; researcher, publisher and library are developing into new directions. Researchers themselves are taking a more active part in the discussion, with the boycott list from the Public Library of Science organization as an illustrating example. Reforms are being launched partly as an economical and efficiency issue, partly as an increasing desire from researchers to maintain the control of scientific end result. This Master s thesis examines how the partly conflicting goals of the participants affect the conditions for scholarly publication in an electronic environment.
