Vägen till en färdig textil

This work describes the process from sketch to functional textile. Starting points are thoughts about the transition from sketch to fabric, and the possibility to sketch before decisions are made about the quality of the final fabric. The first result of this study is the final product, a hand weaved clothing in thin wool that fulfils set demands. The second result is the knowledge that it is possible to make a purposeful sketch without knowing the final product..

Konflikten mellan bevarandekrav och tilläggsisolering : The conflict between conservation requirements and additional insulation

Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.

Selenium in Swedish sheep production

Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px?s), are important as antioxidants and protects against free radicals. The activity of GSH-Px is strongly regulated by Se storage in the liver.

Potentialen av värmebesparing i ett avlopps luftningsledning

This thesis aims at determining the heat losses in a property vent stack and its roof valve. Upon request of a company, the vent stack is analysed for possible heat recovering solutions to be implemented, while relining of the drain system is executed and with a suitable payback time for the economic investments. The heat loss calculations are based on data for properties that are located in the Stockholm region, but also easy to change depending on the situation. The calculations are done on pipes made out of cast iron, which still is the most common type of drain pipe in Sweden, and these are the pipes that relining is usually made on. The calculations that needed to take several variables into account have been done in MatlabR2014a and the thermos dynamical properties that were used in those calculations have been extracted from EES.Three different types of heat losses in the vent stack have been taken into consideration in this thesis.

Energiförbättrande åtgärder på befintliga flerbostadshus : -En lönsamhetsanalys

The EU Council adopted in 2007, environmental and energy goals with the aim of them must be met by 2050. This, in combination with those of the Swedish government 15 enacted environmental goals is supposed to lead the way for the Swedish environmental work.This report has examined measures in properties in the Swedish Cooperative Housing Society (SKB) stocks.The report discusses a range of measures that might be appropriate to apply on the properties to make them more energy efficient.One of the measures discussed, the vent whose primary purpose is to create a good indoor environment for the residents but is also where the most energy is lost.Another measure discussed is insulation of the building envelope on the estate to make it more energy efficient. To put extra insulation on the building envelope is important because of the large amount of energy that is lost through the walls, ceilings and floors.Future actions that may be implemented is individual billing of heating and hot water. This system has been used in European countries since the 70's and today the EU wants to increase the own individuals control over their electricity costs. This has led to a discussion whether to implement the system in Sweden or not.However, there are a number of equitable measures to be sorted out before the system can be used in any great scale.Finally, it is important to remember that environmental measures should be the primary and the pursuit of cost reductions the secondary otherwise you risk the environmental work to be counterproductive..

Preparering av kabelände inför statorlindning

At Uppsala university scientists have during the last years developed and built wave energy converters. This project is called "Lysekilsprojektet". The development has come so far that they are currently investigating how to gain profit in a mass production. For that reason they want to automate as many steps in the production as possible.The winding of the stator is one part that is being automated using industry robots. The stator is cable wound unlike many other generators.

Energieffektivisering av befintliga sjukhusbyggnader - Analys med avseende på kostnad och energibesparing

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

Studie av värmeflöden i befintligt bostadsbestånd : Utvärdering av energieffektiva besparingsåtgärder

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

Fastighetsägarens ställning vid mineralprospektering

Den 1 juli 1992 trädde minerallagen (1991:45) i kraft och ersatte gruvlagen (1974:342), samt lagen (1974:342) om vissa mineralfyndigheter. Genom ikraftträdandet kom den gruvrättsliga lagstiftningen att bli enhetlig. Minerallagen är en exploateringslag vari en avvägning gjorts mellan markägarnas, prospektörens och samhällets intressen. Denna uppsats har syftat till att undersöka fastighetsägarens ställning vid mineral- prospektering. Framställningen bygger främst på förarbetena till mineral- lagen och 1974 års gruvlagstiftning.

Energieffektivisering av modern tillbyggnad till äldre skola : fallstudie från Österbyskolan i Österbybruk

The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.

Prefabricerade passivhusväggar

Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

Specificering av produktionstransformatorer : Rekommenderade avsteg från IEC 60076 för att vid upphandling beskriva en robust enhet

As break downs of production transformers are costly and often result in long outages it is essential for reliability of operation that the transformers are manufactured to be robust. The aim of this M.Sc. thesis is to investigate if deviations should be made from the standard IEC 60076 ? Power Transformers in order to describe a robust large power transformer for procurement.The investigation has been conducted in three stages. In the first stage a definition of the term robust was developed in consultation with the client Vattenfall Vattenkraft.

Energi- och kostnadseffektiva klimatskal : För lager-, industri- och kontorsbyggnader

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.
