This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Gröna lösningar - en fallstudie av aktuell teknik för energieffektivitet för Skanska Sverige ab
ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.
Värdet av att bygga grönt för kommunala bostadsbolag
AbstractThe real estate sector is today responsible for 40 per cent of the total amount of energy consumption within the members of the EU. All over the world there are collaborations within research and projects to find ways of reducing the amount of energy consumed by the real estate sector. In Sweden, a directive from the European Union has posed demands on authorities as well as on the private sector to reduce the amount of energy consumed by new building constructions. Together with the directive from the EU there are also new requirements and demands from Boverket for the real estate sector. These requirements mostly concern the energy consumption of kilowatt-hour per square metre and that the consumed energy also should be renewable. The aim of this study is to explain what kind of value municipalities experience in using certifications and environmental investments for new and existing buildings. Within the chapter theory, essential areas are described such as; environmental certification systems, economical viability, proceeds connected to building green, difficulties with building green, the performance of green buildings when affected by the behaviour of tenants and customer value. The following chapter describes the methodology with which we have conducted this study.
Skolledares uppfattningar av speciallärares arbete
The essay treats how a process of implementation was executed and the teachers? relation to two curricula, Lpo94 and Lgr11, with two different grading systems, which have functioned as models for one and the same year. The purpose is to investigate the ways in which a change in curricula and syllabus affects teachers in their teaching and assessment practice in the subject of Swedish at secondary school. The investigation had a phenomenological approach and was executed by means of in-depth interviews, questionnaires and one observation. The results are based on a methodological triangulation with qualitative and quantitative data where visible similarities and differences are brought out.
Lönsamhet i svenska banker - En tidsserieanalys av de svenska storbankernas lönsamhet och risktagande
This study aims to scrutinize the four major banks in Sweden on how their profit havedeveloped over a time span of 15 years, whether stricter regulations have had anyimpact on financial key ratios and if there is any correlation between the banksprofitability and their risk taking. The period covered is the years 2000-2014. Thefigures are annually and the four major banks are; Handelsbanken, Nordea,Skandiviska Enskilda Banken (SEB) and Swedbank.The findings are that financial key ratios that include net income are pro-cycle whereSwedbank has the biggest volatility over the period and that the three other banks areless, but clear pro-cycle. There are also indications that stricter rules have madeimpact on the volatility of the profitability even though the period covered is notenough to ensure this claim. Nordea has had the lowest and most stable capital ratiothroughout the period and the other three banks lowered their debt-to-equity ratiosignificantly after the financial crisis in 2008.
Att bedöma lärares arbete : En kontrastiv studie mellan kommunala skolor i Sverige och internationella skolor om skolledares arbete med bedömning av lärare
Syftet med denna komparativa, enkätbaserade studie var att synliggöra eventuella skillnader i uppfattningen om processen för bedömning av lärares prestationer hos skolledare i några skolor i Sverige och på några internationella skolor. I litteratur-genomgången gick jag igenom ett antal faktorer alt. delmoment som skulle kunna stödja en systematisk utvärderingsprocess och jag placerade in lärarutvärdering som ett led i skolutvecklingsarbete, ett led i den enskilde lärarens professionsutveckling och ett verktyg som stöd för att individuell lönesättning (på de skolor där lön/anställnings-kontrakt kopplas till prestation). Sex olika förutsättningar för utvärdering av lärare presenterades, vilka kopplades till ett systematiskt arbete med lärarutvärdering på skolor. Utifrån dessa ställde jag upp två utgångspunkter, vilka jag avsåg att utvärdera genom denna enkätundersökning: att skolenheter som har en tydlig vision/mission/värdegrund har en mer strukturerad process för bedömning av lärares individuella prestationer och att skolledarna på de internationella skolorna som deltar i undersökningen genomför en mer systematisk utvärdering av lärarnas arbete.
Bedömningsinstrument användbara för arbetsterapeuter vid bedömning av bostadsanpassning för vuxna med främst fysisk funktionsnedsättning-en litteraturstudie.
SammanfattningSyftet: Att sammanställa vad som fanns beskrivet i vetenskaplig litteratur om bedömningsinstrument som kan användas av arbetsterapeuter för bedömning av behov av bostadsanpassning för vuxna med främst fysiskt funktionsnedsättning. Metod: Systematisk litteraturstudie med sökning på fyra sökord i sju databaser. För att få ytterligare information om de funna bedömningsinstrumenten gjordes en manuell sökning via artiklarnas referenslistor för att kunna besvara frågeställningarna. Resultat: Författarna fann sju bedömningsinstrument som bedömde olika aspekter av miljön i relation till person och/eller aktivitet. Inget av bedömningsinstrumenten var avsett att enbart bedöma behovet av bostadsanpassning. Resultatet styrker behovet av bedömningsinstrument som innehåller både observation och självskattningsmoment för att få en helhetsbild av miljöns tillgänglighet och användbarhet. Konklusion: Arbetsterapeuter som bedömer behovet av bostadsanpassning behöver bedömningsinstrument som mäter både subjektiva och objektiva aspekter av hemmiljö.
En pilotstudie för validering av den svenska versionen av CMPS-SF ? gradering av akut postoperativ smärta hos hund vid ortopedisk kirurgi och mjukdelskirurgi
One of many difficult issues in veterinary medicine is the assessment of an animal's experience of pain. As a licensed veterinary nurse in Sweden you are obligated by law to work by the concept of evidence based medicine. To achieve this the author of this study sees the need for standardized methods of pain assessment. A Swedish version of Short form of the Glasgow Composite Measure Pain Scale (CMPS-SF) has recently been translated and developed. Furthermore, a psychometric validation needs to be performed to ensure its validity and reliability.
Design av försöksanläggning för trycksatt rökgasrening vid oxy-fuelförbränning
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.
Hur bedömning kan främja elevers lärande
Syftet med det här examensarbetet är att beskriva hur lärarens bedömning kan påverka elevers lärande positivt samt att undersöka vilka bedömningsformer lärare använder sig av. Med vårt examensarbete vill vi utöka vår kunskap om bedömning och beskriva vilka konsekvenser olika syften med bedömning kan få för eleven. Vårt mål är inte att generalisera, utan att ge en bild av vilka uppfattningar som kan finnas hos lärare. Vi har genomfört fyra kvalitativa intervjuer med lärare i år 4-6 och det är deras utsagor samt relevant litteratur som examensarbetet bygger på. Formativ bedömning, dvs.
