Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

County Branding : En studie i kommuners marknadsföring mot företag

There is a mutual dependency between the business world and the country?s municipalities. The municipalities are dependent on the companies to create work and tax income while the companies are dependent on the municipalities they are located in to provide good infrastructure among other things.Apart from this the municipalities can work activly with creating a strong brand in the eyes of the companies and many researchers in marketing agree that marketing of places will be more common in the future. Marketing of municipalities is however still a rather new and unexplored area and it is uncertain how and to what extent the municipalities work with this.The thesis is formulated:How are the municipalities working to market towards companies and is it possible to make out any positive change from these marketing efforts?The goal of this study is:Our goal is to examine how the view of marketing of places differs from different municipalities in the Stockholm region, how some of these municipalities work with this and how far they have come in this work.

Klimatförändringarna i nyhetsdiskursen : En kritisk diskursanalys av klimatrapporteringen i Dagens Nyheter och New York Times

Titel: Klimatförändringarna i nyhetsdiskursen Antal sidor: 47 Författare: Emelie Sahlström & Sofia Öström Handledare: Ulrika Olausson Kurs: Medie- och kommunikationsvetenskap CPeriod: HT 2010Universitet: Avdelningen för Medie- och kommunikationsvetenskap, Institutionen för humaniora, utbildning och samhällsvetenskap, Örebro universitetSyfte: Syftet med denna uppsats är att undersöka om och i så fall hur klimatförändringarna i nyhetsdiskursen i New York Times och Dagens Nyheter har likheter, respektive skiljer sig åt. Vi undersöker också om klimatrapporteringarna är uppbyggda genom nationella eller globala identitet, om något ansvar utkrävs samt vilka som tillskrivs detta ansvar och om det finns en vetenskaplig säkerhet eller osäkerhet gentemot klimatförändringarna. Utifrån dessa har vi i slutdiskussionen diskuterat hur resultaten kan kopplas till USA:s och Sveriges klimatpolitik.Teorier: Teorierna är relaterad och presenteras i relation till tidigare forskning. De teorier som används i denna uppsats är, ansvarsutkrävande, vetenskaplig säkerhet och osäkerhet samt identitet. Metod och material: För att uppfylla syftet använde vi en kritisk diskursanalys samt mikro- och makronivåerna. Vi har analyserat 8 artiklar från New York Times och 9 artiklar från Dagens Nyheter.Resultat: Resultaten visar att DN och NYT, som Europa och USA står mot varandra i klimathanteringen.

Termisk energilagring i borrhål : En studie av borrhålets temperaturinverkan på värmepumpens värmefaktor

Sverige har en hög andel installerade bergvärmepumpar, som är en typ av vätska-vatten värmepump. Ett problem som finns för befintliga bergvärmesystem är att berget med tiden kyls ned då returslangen till borrhålet konstant levererar kyla till berget. Till följd av detta mister systemet en betydande del av sin verkningsgrad samtidigt som det i extrema fall kan leda till permanent isbildning i borrhålet.Ett sätt att motverka detta problem är att tillämpa termisk energilagring i bergvärmesystemets borrhål. Den internationella benämningen för denna teknik är ?Borehole Thermal Energy Storage, BTES?.Rapporten har behandlat en friliggande enplansvilla med ett befintligt bergvärmesystem som tillämpar termisk energilagring i bergvärmesystemets borrhål med solvärme.

Närproducerat : Attityder och definitioner bland Uppsalastudenter

From an environmental and climate perspective we are becoming more and more aware of what we eat. Consumers want to know how their food is produced and where it is coming from. A term commonly used in this discussion is local produce. At this time, there is no clear definition of the term and a wide range of definitions can be found. However, despite this lack of definition, the term is often being used by producers, traders and consumers..

Geografiperspektiv

AbstractOur world is facing new challenges depending on the climate changes. The UN panel of climate changes has determined that the human race is responsible for the changes, but also that we have the opportunity to reduce the effects. This demands that the information reaches out to the public which means that the school system carries major responsibility to this type of questions. This also means that the teachers have to be observant, and give the questions the attention which is needed. The purpose of this essay is to see if this awareness exists today among active teachers and teacher students and if the perspective differs among them, but also their opinions is in agreement with the course plan in the subject.

Klimatkabinett : Komponenter och konstruktion

This report describes the construction of a climate-cabinet for testing of HV-cards (High Voltage) produced at VG Scienta. The main part of the report describes all the different components of the cabinet. The most important parts are a PID regulator from Eurotherm model 2408, a solid state contactor (SSC), a thermocouple, a finned resistor from DBK and different fans. The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.

Nötköttsproduktion i Västerbotten

Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.

Det moderna risksamhället: En studie om klimatrisker inom kommunal krisberedskap

Klimatförändringarna är numera ett fenomen vi inte kan bortse ifrån. De sker här och nu och det råder mer eller mindre gemensam vetenskaplig konsensus om att så är fallet. Med klimatförändringarna kommer risker vi i nuläget har väldigt svårt att förutse och förhålla oss till och därmed påverkas integrationen av dessa i den kommunala krisberedskapen. Syftet med studien är att undersöka vilka faktorer det är som påverkar integrationen av klimatrisker inom den kommunala krisberedskapen. Resultatet är baserat på ett antal intervjuer som har genomförts med personer inom kommun och kommunfullmäktige.

Flygets framtid : Från problem till möjligheter

The purpose of this essay is to investigate the airline industry and its part in the mobile community. Further on, to investigate the factors that throughout history are having an impact on the airline industry and have lead to the condition of today. Through this information we are outlining the future of the airline industry.This essay has been written in a qualitative approach. The empirical gathering has been made through interviews based on open discussions between the interviewers and respondents. We started out with creating a theoretical pre-understanding and continued by comparing how well these theories matched the reality.The gathering of the theoretical material was chosen on the basis how well it matches the subject of our essay.

Ekosocial välfärd : En kunskapsöversikt

There seems to be a consensus in the world that the climate is changing, bringing unpredictable and severe consequences for both humans and nature. The feld of social work is known for helping misfortunate individuals and groups, and is said to deal with people in their environments. Yet there seems to be a lack of giving these environments meaning as also something natural. This thesis has the purpose of exploring the connection between social work and the physical environment made by research literature, using the methodology of literature review. The questions asked is in which ways the physical environment can be connected to human welfare; if so, what implications are there for the feld of social work, and fnally how can the discussion be understood using a typology over environmental sustainability presented by Andrew Dobson.

Planering och projektering för individuell mätning och debitering i flerbostadshus

The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.

Konvertering från luft till vätskekylning av elektronik

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet

There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes. District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption Research), which has focused on climate adaption in the Nordic countries.
