The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.

In the global and rapidly changing society Environmental scanning is becoming a more and more important tool. Today it is not the availability of information that controls an organizations behavior, but the information that the organization chooses to absorb. This is the case for a multinational cooperation as well as for the local golf club. Swedish golf clubs have during the last 100 years had an amazing development and today there are almost 600 000 registered Swedish golf players. The development has however stopped and even declined some during the last couple of years.

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.

Al Gore may have helped put global warming on the agenda. However, it is not a new subject. Neither is so called green marketing a new phenomenon within branding and communication. As more and more companies establish environmental strategies there exist beliefs that the environmental focus is becoming a triviality, which is the reason for this study. Implementation of words such as ?environmentally friendly?, ?green? and ?global warming? is becoming more and more widespread and frequently used within marketing communication.

In January 2005 large forest areas in south Sweden were severely damaged by storm. This final thesis describes the work with creating an ecological and landscape-adapted regeneration plan for a severely storm damaged property in Kronobergs region in south Sweden. This regeneration plan, in difference to more regular plans, are focusing more on the owner?s use and goal?s for the property and seeing the property from a more comprehensive view in the regeneration process. Beside production and environmental values the plan also take in consideration other values as aesthetic, culture history, landscape picture and recreation values.

Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters. The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

In a time of increasing urbanization the human tenure effects on the land has lead to a decrease and fragmentation of areas that are valuable to urban wildlife. These actions have had a detrimental effect on the species and habitats that exist in cities and towns.This paper investigates, through the study of relevant literature and the undertaking of interviews and field visits, the role that biodiversity plays in our society. The current attitude towards urban biodiversity and the responsibility for its promotion within the landscape architect profession has been explored.This paper includes three English case studies and a design proposal investigating how one can work to promote biodiversity on a smaller scale.This paper concludes that urban biodiversity is multi-functional ? being of ecological, social and cultural significance. The landscape architecture profession must be aware of the need to combine a variety of different factors such as economical, social and environmental aspects.

Global climate change is one of the greatest challenges in our history. As the average temperature is rising due to anthropogenic emissions, impacts such as floods, droughts and hurricanes, affect the lives of millions of people. Though the least developed countries are least responsible for emissions, they are the worst affected. This thesis focuses on environmental justice in the adaptation discourse. By outlining the adaptation discourse from the United Framework Convention on Climate Change principles, to the Marrakesh Accords, via the Kyotoprotocol my ambition is to analyse how environmental justice has been interpreted in relation to the adaptation discourse.

AbstractThe aim of this Master thesis is to explore why some Swedes want to consume?eco-friendly? and whether this fact gives rise to articulated information needs. Two possible explanations for this ?eco conscious? consumption are being tested, either if it is based on a normative belief that it is the right thing to do if you, as a consumer, want to do something about the environmental degradation, or that it is a reaction to a perceived risk, due to the environmental degradation. The method chosen by the author in this thesis is a qualitative text analysis of five Swedish journals.
