Livscykelkostnader för vindkraft : En jämförelse av fallstudier

I denna rapport har det utförts två fallstudier från två olika vindkraftsanläggningar och med hjälp av en utarbetad modell har livscykelkostnaderna jämförts för de två fallstudierna.Resultatet visade att livscykelkostnaden per producerad kWh sjunker allteftersom den installerade effekten blir högre.Kostnadsmodellen som utarbetats och tillämpats för resultaten har visat sig ha hög verifierbarhet då resultaten har varit jämförbara med litterära studier..

Life Cycle Cost : Studie om LCC som verktyg att utva?rdera geoenergianla?ggningar

Life Cycle Cost, often abbreviated as LCC, is a common tool for comparing the total cost of different alternatives, such as heating and cooling methods. Common heating and cooling methods in Sweden are geothermal energy, district heating and district cooling. This report aims to evaluate how different heating and cooling methods differ from each other while being applied on three different types of buildings, using selected LCC-models. Information about the selected LCC-models wasretrieved from each separate model and its website. Reports and agencies were used as sources for information about the heating and cooling methods.

Upprustningsmetoder för en bankropp : En jämförelse ur ett LCC-perspektiv

In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.

E-arkivering hos stadsarkiv : Mellanarkivslösning i sitt sammanhang

Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.

Utformning av sidoområden med hänsyn till vägens livscykelkostnad

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Finansiella garantier - en möjlighet att säkerställa ett miljömässigt omhändertagande av uttjänta produkter

Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.

Livscykelanalys av en gängtapp - Underlag och verktyg för att inkludera livscykelperspektivet i utvecklingsarbetet vid Dormer Tools AB

The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

Barns tolkning av en modell för vattnets kretslopp : -förståelse och tillämpning

AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.

Jämförelse mellan en träbro och en betongbro : En LCA-analys med fokus på koldioxidutsläpp samt en LCC-analys

Förbehandlingstekniker och LCA för rötning av organiskt avfall : Modellkonstruktion och Utvärdering med ORWARE

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

Från Bomull till Byxor Livscykel Inventering och Ansvarsfullt Företagande En MFS i Södra Indien

A growing number of companies realise that to achieve their environmental goals and satisfy stakeholder expectations, they need to look beyond their own facilities and to involve their suppliers in environmental initiatives. A life cycle approach means that the production system should be optimised as whole, across national boarders and individual organisations taking part all the way from extraction to disposal. This study is a Life Cycle Inventory of resources used when producing a piece of cotton garment and the method is based on the standardisation series of ISO 14040-43. The area of study, Tamil Nadu the most southern state of India, accounts for more than 90% of India?s knitwear exports to Western Europe.

Implementering av "Life Cycle Management" i svensk läkemedelsindustri

It generally takes 10 to 12 years for a new drug to hit the market. The pharmaceutical industry invests huge sums in these early stages of research and development. In spite of the rapidly rising research and development expenditures fewer and fewer blockbuster drugs are being developed. Longer lead times and aggressive generic post-patent competition have narrowed the timeframe for the pharmaceutical companies to profit on their investments.In the face of these threats the pharmaceutical industry has developed a battery of strategies to prolong market exclusivity and to maximize return on investment. These emerging strategies are commonly known as Life cycle management (LCM), which actually is more of a concept than a method.

Livscykelanalys för koldioxidutsläpp från flerbostadshus

Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.

Livscykelanalys av flerbostadshus ? energieffektiviseringsåtgärder för minskade koldioxidutsläpp

The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.
