Passivhus med prefabelement : En jämförelse mellan en platstillverkad konstruktion och prefabelement från Masonite Lättelement AB
This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020..
Geoenergilösning för DN-huset
In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.
Konsekvenser av energimodellerad arkitektur
The interest in building low energy houses has increased along with the rising engagement inthe climate questions. With the advancing energy prices it is highly suitably for those whobuild and administer their buildings in long-term to build energy-saving houses. 40 % ofSweden?s total energy consumption constitutes of the energy in residences, therefore it iscrucial to take advantage of all the free energy as we possibly can. With crucial questions likequality of living and profit low energy building is a subject that concerns us all.Three proposals for apartment blocks are presented in this work on a real estate in Stockholm.Each proposal is developed through unique processes of design with the purpose to displaypossibilities to deal with the energy requirements of today and tomorrow through energybased architecture.The first proposal is an apartment block based on a traditional design process, the demands ofthe property owner and it?s affected by opinions from architects.
Balansering av en storskalig vindkraftsutbyggnad i Sverige med hjälp av den svenska vattenkraften
This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.
Samha?llsplanering med BREEAM Communities : Certifieringsverktygets pa?verkan med ha?nsyn till miljo?ma?ssig ha?llbarhet
I takt med urbanisering och samha?llstrender har utvecklingen och samha?llsplaneringen av sta?der blivit allt viktigare. BREEAM Communities a?r ett relativt nytt, brittiskt, certifieringssystem fo?r stadsdelar och fungerar som ett verktyg samt bedo?mningsunderlag fo?r samha?llsplanerare. Verktyget fungerar som ett systematiskt underlag fo?r att kunna bygga ha?llbara stadsdelar och tar sa?ledes ha?nsyn till alla tre dimensioner av ha?llbarhet; sociala, ekonomiska och ekologiska.I Sverige har stadsdelscertifiering pa? senare a?r uppma?rksammats.
Livscykelanalys av en gängtapp - Underlag och verktyg för att inkludera livscykelperspektivet i utvecklingsarbetet vid Dormer Tools AB
The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.
Energieffektiva värmesystem : Lösningen till att nå energimålen i byggbranschen?
Sweden has an environmental goal to achieve until the year 2020. To achieve this goal the construction business has to take an initiative to use the modern techniques that are available to lower the energy consumption I buildings. There?s also a debate going on today regarding the energy demands set by the Swedish government through Boverket, some communities throughout Sweden thinks that the demands are to low and have therefore set up own demands regarding energy in buildings.The possibility to construct energy-saving buildings is today very great, with energy-efficient heating-systems and dense climate envelope. The interest to raise energy-efficient buildings have also increased as a consequence that the population have become more aware about their impact on the environment.
Dagvatten i Märsta : förslag till anläggning för ekologisk hantering samt metodöversikt
Stormwater in urban areas has been treated as a problem for a long
time. The large proportion of impermeable surfaces inhibits the water
from infiltrating in the ground to the same extent that it does in nature.
This causes intensive surface flow during rain, which in turn causes
inconveniences such as decreased accessability, floods and increased risk
of desease spreading. Drainage through pipes is the traditional and usually
functional metod for storm water disposal. That is as long as water flows
are moderate. But precipitation varies naturally in amount and intensity
and additional impermeable surfaces make some pipes insufficient for
heavy or lasting precipitation.
Högskolestudenter och alkohol : Akademisk locus of control i förhållande till alkoholrelaterade studieproblem
Studenter är bland de som konsumerar mest alkohol i Sverige. Hög alkoholkonsumtion och extern akademisk locus of control (ALC) har liknande negativ effekter på studier. Denna studie undersökte relationen mellan alkoholkonsumtion, ALC och alkoholrelaterade studieproblem. 120 studenter, varav 91 var kvinnor, deltog genom att besvara en enkät bestående av The Academic Locus of Control Scale for College Students, the AUDIT Alcohol Consumption Questions och en egenkonstruerad skala som mätte alkoholrelaterade studieproblem. Data analyserades med en 2 (riskbruk/ickeriskbruk) x 2 (extern ALC/intern ALC) ANOVA för oberoende mätningar.
Miljöcertifieringssystemet BREEAM ? En studie av processen och dess effekter
Denna kandidatuppsats behandlar miljöcertifieringssystemet BREEAM med fokus på processen och systemets effekter. I studien har pågående BREEAM-projekt i Sverige studerats för att undersöka vad som görs specifikt vid en BREEAM-certifiering, vad det kostar samt vilka nyttor en BREEAM-certifiering genererar.Bygg- och fastighetssektorn står för en betydande del av miljöpåverkan i Sverige idag och förhoppningen är att miljöcertifieringar av byggnader kan minska miljöbelastningen. Studien visar på att det finns en växande efterfrågan på miljöcertifierade kontor och lokaler från hyresgästen trots att innebörden än är något oklar.BREEAM är relativt nytt på svenska marknaden och behöver fortsätta att utvecklas och anpassas. Ett svenskt företag, med en redan god intern byggstandard, behöver dock inte göra några större åtaganden för att nå ett bra betyg i BREEAM. En BREEAM-certifiering intygar att en byggnad håller en bra nivå miljömässigt, visar att företaget är på väg åt rätt håll och hjälper till att strukturera upp miljöarbetet under ett byggprojekt.
Comparison of Different Electrophoretic Methods for Haptoglobin Phenotyping and an Investigation in Patients with Abdominal Aortic Aneurysm
Haptoglobin is an acute phase protein with important biological role because of its capacity to bind to haemoglobin. Haptoglobin exists in three major genetic polymorphism types: Hp1-1, Hp2-1 and Hp2-2, the distribution of which has been associated with abdominal aortic aneurysm (AAA), an asymptomatic aortic disease common among men older than 65 years. Five different electrophoretic methods were tested according to their ability to separate the haptoglobin phenotypes. The detection was based on a produced hemolysate of blood in which haemoglobin binds to haptoglobin thereby forming a complex that can be detected by specific haemoglobin staining using TMB-dihydrochloride and hydro peroxide as substrate resulting in an azure-green color of the bands. Samples from 15 patients who had suffered surgery for not broken AAA, that is more than5.0 cmaortic diameter, and 15 samples from matched controls were analyzed. Among the five tested electrophoretic methods best migration and separation was seen on the pre-cast agarosgel Hydragel HR on the instrument Hydrasys. The other four methods gave less successful results.
Utvärdering av energiberäkningsprogram : Att användas i tidigt planeringsstadium för byggnader
The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building?s physical characteristics for reliable energy analysis.
En energieffektiv byggarbetsplats : En studie av Skanskas bostadsprojekt
The construction industry has demands on energy use in permanent buildings. How much energy that is permitted to use during the time the building is produced has no requirements. The purpose with this study is to learn how far Skanska has come with the work of making the building site more energy efficient.A literature study has been performed in the beginning of the study to survey what energy efficient arrangements that can be applied and how they operate. Using site visits and interviews the situations on the building sites have been studied as well as the energy efficient measure that are in use.Skanska has come a long way with the work of energy efficient building sites and they keep improving. They have improved half of their cabins so they use 50 % less energy.
Europeisering och politisk integration av nationella politiska partier : En studie av Vänsterpartiets och Miljöpartiets utveckling i synen på det europeiska samarbetet 1987-2010
This paper examines if European integration has had an impact on national political parties by looking at the stances of the Swedish Green Party and the Left Party on the issue of the European Community and the European Union over time. With the development of the European Community and the European Union, national political parties face the challenge of an emerging political arena. European integration research has recently become more involved with what is called europeanization and political integration within the member states them self, this paper aims to provide further leverage to the thesis that national political actors undergo some degree of europeanization and are politically integrated in the EU, by examining manifestos of two historically eurosceptic Swedish political parties. The theoretical framework provided by neo-functional integration theory as well as europeanization is used to examine the empirical material in order to see if the political parties at the focal point of this study can be said to have undergone a change in political policy regarding the EC and EU, both in quantity and content. The analysis show that indeed both parties has undergone a change and what might be considered a europeanization, considering that the presence of the EU as a political issue seem to have risen in prominence and importance in the examined manifestos.
Annonser och nyhetskonsumtion : En kvantitativ studie om hur unga vuxna irriteras av annonser på nyhetssidor på PC och iPad
In this paper we have studied how young adults read news on the internet. The purpose was to seehow the consumers of news were irritated by the adverts on news sites depending on whichplatform they used, a computer or an portable reading device of the brand Apple iPad. Observationsand surveys were conducted on ten people. The news sites we used for this study were www.SvD.seand www.expressen.se. The result show that a majority experienced that their news consumptionwere irritated by advertising, mostly on Expressen's news site because it wasn't perceived asforeseeable..
