Återvinning av industriell restvärme som värdeskapande process : En fallstudie på SSAB EMEA i Borlänge

The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted as a tool to assist the industries in their efforts to change the relationship between the consumption of energy and production. This by improving energy efficiency and a shift to the best available technology. During the past 30 years the steel industry has reduced its energy consumption per ton of steel produced by 50 percent.

 Solenergi En del i ett långsiktigt, hållbart byggande

The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.

Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

Kvarteret Kajutan - Från lågenergi till plusenergi

Energy and environmental demands regarding buildings have become an increasinglydiscussed topic, both in Sweden and in Europe as a whole. The general trend indicatesthat greater efforts are being put into the energy efficiency of the built environment.There are already numerous examples of houses with a low energy demand, and thenumber of low energy buildings is constantly growing.At the time being, the maximum level for energy demands for housing in Stockholm is110 kWh/m2year, but as soon as next year the limit will be changed to 90. The Swedishagency Energimyndigheten is currently conducting a project to interpret the EU Directiveon the so-called Nearly zero energy buildings, and the preliminary results indicate thatthe level of requirements for purchased energy will end up with about 55 kWh / m2year,which is in line withtoday?s recommendationsfound in FEBY's Kravspecifikation förPassivhus.Starting with a low-energy house in Henriksdalshamnen in Stockholm, we have analyzedvarious energy-efficiency measures and their influence on power and energy needs. Thefinancial aspects associated with the measures have been studied using a model of lifecycle costs.The measures were initially studied individually to give an idea of how much impact theyeach had.

Olika metoder och tekniska hjälpmedel för att bestämma bevattningstidpunkt :

This examination work on studies and research in articles is mostly from other countries. The purpose of the examination work have been to find out if there are any means you can work with to find out when its time to start irrigation, how they works and if they are credible. In Sweden there is not many means for decide when it?s time to irrigate and how much water you should appear. Swedish farmers think they have so much experience that they don?t need techniques like this.

Kv. Tvättstugan, ett flerbostadshus med massiv trästomme : Ett examensarbete om akustik- och brandkrav samt en jämförelse av energi- och fuktaspekter

Title: Kvarteret Tvättstugan, an apartment building with massive wood construction. A thesis about acoustic and fire requirements and a comparison of energy and moisture aspects. Earlier restrictions in the Swedish legislation have resulted that only a small percentage of the apartment buildings that have been built are designed with a massive wood construction. It has been allowed to build unrestricted with wood since 1994 as long as the function of requirements are fulfilled. This change in the rules together with the great environmental benefits of wood has led to that more companies choose to build apartment buildings with wood. One of these companies is Folkhem Production AB.

Effektivitetsparadoxen - En eventstudie av handelsstopp på Stockholmsbörsen mellan 2003 och 2008

A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.

Sambandet mellan saldodifferenser och effektiva materialflöden : Fallstudie utförs på Atlas Copco?s logistikavdelning

Problems arise when the number of products in stock does not correspond with the number of products the information system says the company has in stock. (Sharda & Agrawal, 2012) In order to change that, major changes has to be made when it comes to making continuous improvements and to raise their standards regarding product availability and record inaccuracy (Wild, 2004).The purpose of this study is therefore designed to identify factors affecting the balance differences and what impact it has on the efficiency of material flow. The demarcation of the work is that Atlas Copco has begun working with Lean and it will not be investigated nor the relationship between balance differences and Lean. The study was based on answering the following questions: What influencing factors can be identified for balance differences? What factors are relevant to the efficiency of material flow? What kind of impact the balance differences has on these factors?In order to answer the purpose and issues, a theoretical framework has been developed with help of literature studies and an analytical model.

Dedikerade kontra Responsiva webblösningar : En studie av mobila webblösningar inom tidningsbranschen

Uppsatsen behandlar ämnet användbarhet i mobila webblösningar med inriktning mot tidningsbranschen. En jämförelse mellan de två aktuella designfilosofier, dedikerad design och responsiv design, för den mobila webben har utförts genom att fokusera på användbarhet, där centrala begrepp studerats. Begreppen är som följer: Usefulness, Efficiency, Effectivness, Learnability, Satisfaction. Mixade metoder i form av enkätstudier, heuristiska tester, användartester, intervjuer och prestandatester har utförts för att samla in empiriskt material för analys och för att sedan ge en slutsats angående vilken av de två designfilosofierna som tenderar att ge hög användbarhet i system som exempelvis tidningssajter i mobilen.De mest intressanta resultaten var att, sett ur användbarhetssynpunkt, var båda designfilosofier likvärdiga, majoriteten svarade att de testade sajterna fungerade på liknande sätt. Alla uppgifter kunde utföras utan större problem på båda sajterna vilket uppfyller kravet för effectivness.
