Standardisering av brukarrelaterade indata för energiberäkningar på kommersiella lokaler
In this thesis, input data for energy performance calculations on commercialpremises have been studied. In energy performance calculations, where internal heat gain parameters are unknown, template values that, in a reasonable way represent the activity in the room, are necessary. These values can be used as input data for whole-year calculations, or for calculations on shorter periods of time.The purpose of the Sveby project is to create standardized work practice in energy issues for the construction industry. The work in this thesis is conducted to correlate with the purpose of the Sveby project, with aims of contributing with information and guidelines for the continuing work with commercial premises.In this report, suggestions for template values for internal gains parameters, based on research and calculations in the field are presented. Suggestions on how these can be implemented in a user-friendly way for two energy performance calculation software are also given, VIP Energy and IDA ICE.
Produktionsvåtmarker mot övergödning
In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.
Designa Koncept för Spelvärlden
The process of producing a video game is one that goes through a number of phasesduring the span of the entire production. One of these phases is the concept design phase,which is part of the pre-production. This phase is an important aspect of the productionas it is where all the different parts and ideas concerning the game are brought togetherto define what the game is going to be. Though a clearly important part of the videogame production surprisingly little research have been done on the subject of conceptdesign. This thesis presents what place concept design has in the overall game productionand how the design process is handled.
Att lova guld och grön energi : En diskursanalys av svenska energibolags CSR-rapporter
The environmental situation is becoming increasingly critical. The energy sector and other industries have a big impact on our climate and the public is raising their voice for companies to admit their responsibility towards the environment and society. Companies engage in corporate social responsibility (CSR) and happily disclose their responsible performance in annual reports. But what messages are they conveying in their CSR-reporting, and what attitudes towards CSR can be found underneath the explicit content? The aim of this study is to discover which discourses exist in CSR-reports from Swedish energy companies, and how these discourses operate.
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.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.
Energieffektivisering genom förändrad ekonomistyrning
We have chosen to write our essay in collaboration with Varbergs kommun, where our starting point is to improve energy efficiency by management control. Their occupation separates from a pure profit driven corporation and therefore the management controls have to be adapted accordingly. The reason why we have chosen to write an essay about the management control opportunities to improve the energy efficiency depends on two different reasons. The first reason is that we find it very interesting, how with support from the management control it is possible to improve different parts of the operation. And the second reason is that Varbergs kommun expressed a wish that they wanted to improve their energy efficiency process.The purpose of the essay is to describe and analyze the opportunities with support from the management control to help improving the process of energy efficiency in a municipal operation.
Förskolor med passivhusteknik : En utredning av passiva förskolor
As a result of directives from EU, with the ambition to reach environmetal goals, The German organisation Passivhaus Institut has defined a passive house. A passive house is a building that is very energy efficient and makes a small impact on the environment. The energy from the inhabitants as well as the appliances & fixtures in the building should equal the energy that is required to heat the building. A Swedish version of the passive house definition has been defined, taking into account the climate conditions and the difference in building regulations.This thesis is a request from Skanska on how it can improve and develop an ongoing passive house project, involving an infant school. The intention of this thesis is to identify difficulties & display potential development areas for infant schools.The method of research conducted is as follows: interviews of clients, ventilation consultant, consultant for heating system and an energy calculation consultant, an inspection of the infant shcool in process, investigation of completed infant schools and a study of relevant literature.From this research it was found that it is difficult for infant schools to pass the criteria for passive houses. The conclusion of this thesis provide several guidelines on how to improve the outcome of existing projects & the steps needed to be taken for future development in this area..

Återladdning av bergvärmekonfiguration vid samfälligheten Ängsbacken
Under detta projekt har vi tittat på hur man kan återladda en bergvärmekonfiguration med lågtempererade solfångare. Projektet utfördes åt Newsec Energy i Stockholm vars kund samfälligheten Ängsbacken ville minska andelen tillskottsenergi som utgörs av olja till sin bergvärmeanläggning. En utredning av anläggningen gjordes av Newsec Energy som visade att berget kylts ned och att anläggningens borrhål varit underdimensionerade. Vi fick uppdraget att utveckla en systemlösning med lågtempererade solfångare..
Produktionschefens arbetssituation : Hur deras arbete kan förändras och utvecklas
This report is written in cooperation with Skanska Sverige Hus Väst and it is discussing the role of site managers within the company. The report will bring up the demands that is put upon site managers and will also discuss stress related problems and how to change and develop the role as a site manager.We came up with three conclusions in this report. We believe that Skanska could develop VSAA to make it easier to use for site managers. We also believe that a further development of the project engineer is of great value, to give him or her greater responsibilities. The last conclusion is to change the responsibilities between the site manager and the production manager, to give the production manager a greater responsibility in the production..
Vinkärlsetiketterna berättar : En textstudie
This paper examines the texts written on shards from wine-jars found at El-Amarna, Tutankhamuns tomb (KV 62) and Deir el-Medina. Information concerning the administration of wine and its production, found in these texts, is examined. Wine was an important element in Egyptian society and a common iconographic motif in tombs at Thebes during New Kingdom.A survey on previous research on the subject is presented. This is followed by analysis of the different reoccurring elements found in the texts. A definition of the standard formulation of the wine jar label texts is given and the minimal level of information needed for the administration of wine production and distribution is identified. The chapter of the analysis deals with the various types of information given in the label texts, such as date, wine classification, and function.
Solenergi : en lönsam investering för ett lantbruk?
A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.
Biogas : En systemanalys av Solna Stads matavfallsprocess
Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.
Ännu ett steg i vardagen : En artikelserie om livet med en cp-skada
How affected are the sugar production in Mozambique and Tanzania by EU sugar regime? What does the EU sugar reform constitute in these countries?Using theories regarding free trade and anti-free trade, I am able to answer these questions. The aim of this paper is to study how the various sugar agreements with EU affect the sugar production in Mozambique and Tanzania. Therefore I am using a method called a most similar system design in this comparative case study. The conclusion is that the EU sugar regime is the main reason to how the sugar productions in developing countries are.
