Temperaturzoner för lagring av värmeenergi i cirkulärt borrhålsfält

The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.

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.

Hur lagerhanteringssystem och artikelidentifiering kan bidra till logistisk effektivitet : En fallstudie på Nefab i Runemo

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

En energistudie över Fengerfors bruk : Kartläggning och förslag till effektiviseringsåtgärder hos byggnader av industrikaraktär

I slutet av 1900-talet började man inse konsekvenserna av att förlita sig på icke förnyelsebara energikällor för uppvärmning. Priserna steg i höjden och man valde ofta att byta ut sin oljepanna mot el vilket för tillfället var en lönsam lösning. I och med prisstegringen som skett det senaste decenniet har betydelsen av energieffektivt byggande framstått som allt mer tydlig. Detta innebär att många äldre byggnader ofta kan ha mycket dåliga värmeisolerade egenskaper eftersom både energipriser och byggnormer var lågt ställda vid tiden för uppförning.Uppdragsgivarna till arbetet är en ideell ekonomisk förening vid namn Not Quite med sin bas i Fengerfors bruk, Åmål. De har framfört att de har problem med för höga uppvärmningskostnader och svårigheter med att hålla önskad inneluftstemperatur i deras lokaler.

?H?LLBAR MIGRATION?? En kritisk diskursanalys av Europeiska unionens reglering av asylansvar

This bachelor?s thesis aims to examine how the ?New Pact on Migration and Asylum? construct the discourse on ?sustainable migration? and ?efficiency? in the European Union. The new jurisprudence concerning migration and asylum in the European Union seeks to establish a more ?fair, efficient and sustainable migration and asylum system?. To analyze the discourses, a critical discourse analysis is applied to the former asylum regulation, Dublin regulation III, a revised and withdrawn proposal, Dublin regulation IV, and future legislation.

Norra Djurga?rdsstaden som nollstad : En studie av miljo?projektets sista etapp och dess potential

All around the world more and more people move from rural areas to live in the cities. Because of this, the urban areas have become an important part in the debate about the effects on the environment and sustainability. In many countries word wide initiatives have been taken to build sustainable cities and eco cities, the Stockholm Royal Seaport is one example. The vision for the district is to become a world class sustainable city based on the three dimensions of sustainable development: social, economic and ecologic. The municipality of Stockholm has set requirements for the buildings? energy usage, emissions and amount of waste generated during the building process.

Nyttjande av det digitaliserade stickvägsnätet vid skogsgödsling med traktor

Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

Sexualitet efter en hjärtinfarkt- Behovet av information

Sexuality contains more than just reproduction and is an important part of quality of life. Chronic disease can lead to sexual dysfunction for both males and females. The nurse plays an important role in informing and teaching. Throughout dialogue and observations the nurse can detect possible problems, document and then take measures. The study was performed as information retrieval of literature where the cause was to highlight sexuality for patients that have experienced a myocardial infarction.

Energiförbrukning för Cisco 3560

I dagens samhälle förs det diskussioner hur vi kan sänka vår energiförbrukning i olika sektorer. En av dessa sektorer som förbrukar mycket energi är IT sektorn. De mätningar som har gjorts i USA visar att år 2011, så har energiförbrukningen för datacenters fördubblats jämfört mot år 2006. Strategier har tagits fram för att sänka energiförbrukningen för datacenters och då framför allt på servrar och kylsystem. Dessa strategier benämns med allmäna ordalag Grön IT.

Mot mer flexicurity?

Since the 2006 election, the debate surrounding the Swedish labour market policy has intensified. There has been a discussion about a need for change towards a more flexible labour market. An example of this is on the other side of the strait, in neighbouring Denmark. Their flexicurity model, ?the golden triangle?, is characterized by a flexible labour market, generous unemployment benefits and active labour market policies.

Passivhus, detaljutformning och dess köldbryggor

Along with rising energy prices and increasing awareness of environmental issues, the criteria for buildings energy performance have been sharpened through the years. Today, ?passive house? and ?low energy house? are commonly used phrases in the construction industry and is expected to become increasingly common in the future.For houses with well-insulated building envelope the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the building, compared to the rest of the building envelope.This report deals with detail solutions around windows and a comparison between a traditional slab and a foundation from Koljern consisting of foam glass.

Åtgärder för att energieffektivisera befintliga industrilokaler vid renovering av klimatskal

För att minska energiförbrukningen i Sverige krävs att befintliga byggnaderen ergieffektiviseras. Det finns även befintliga lokaler i landet som är i behov av en sänkt energiförbrukning. Det sker ständigt initiativ kring arbete med energieffektivisering av framför allt bostadshus. När energiförbrukning ska sänkas i industrilokaler läggs fokus på att minska energiåtgången i de invändigaprocesserna men inte i det omgivande klimatskalet där transmissionen utgör en stor del av energiläckaget. Syftet med arbetet är att öka kunskapen om energieffektiva åtgärder vid renovering av klimatskal hos industrilokaler.

Åtgärder för att minimera trafikbullers påverkan på ett rekreationsområde

The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.

Tidsupplösning vid miljövärdering av fjärrvärme : Kontorsbyggnad med solvärmeproduktion - en fallstudie

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

Åtgärdsprogram - utvecklande eller invecklande? : Arbete med särskilt stöd i praktiken

The purpose of this study is to illustrate how three schools work with special education needs, what they consider is special education needs and what measures they put in for the student to achieve the goals. I will also study how the evaluation and the follow-up of the individualized education program work at the schools.The empirical material consists of all active programs in grades 7, 8 and 9, together with and interviews with special education teachers and the principal at each school. The results are compared with similar previous researches and analysed by two dominant perspectives of school difficulties.The result shows that it is mainly the critical perspective that dominates the individualized education program. The student is the carrier of the problem and is excluded in many cases from the other students in the class. These measures are different compensatory accommodations for the student in order to catch up with other students..
