This examination paper is an energy-inventory of Soldathemmet at the regement in Halmstad, in colaboration with Fortifikationsverket in Halmstad. The building is first an foremost for the soldiers, where they can go for a cup of coffee or watch TV. There is also a museum and a drivers school in the building. Calculations have been done with two computerprograms; VIP+ and ISOVER Energy. The results were well matched with the statistics that were provided by Fortifikationsverket.

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.

People have used forest resources in northern Sweden for different purposes. Before the 20th century the forest was used for many different reasons, but during the past 200 years it has become an industrial raw material. The presence of people in the forest has left different kinds of traces in the forests. One example is culturally modified trees (CMT´s). The aim of this study was to study and document how people have used the forest resources during the last centuries in Brännlidens nature reserve, and what kind of traces this land use has left.

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.

The forests in the unique archipelago of the Baltic Sea is housing many and high values. For the resident population, which has a central role in sustaining a living archipelago, the forest can contribute to the outcome. The forest also contributes to turn the archipelago into one of Sweden?s most attractive recreational areas. Furthermore, these forests exhibit very high environmental values, and they are an element in the traditional cultural landscape.

Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness.Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat.

In electricity markets evolving towards liberalisation and internationalisation, green certificates are seen as an important tool to promote production of renewable energy. In a green certificate market producers sell certificates received per unit of electricity generated from renewable energy. Trade in renewability is thereby decoupled from the the physical electricity trade. Tradable green certificates in combination with renewables obligation are implemented or planned in several EU member states. Integration at EU leveland the creation of a common certificate market seem like a possible next step.

Hemp is a versatile plant with many uses that has been around for thousands of years. The plant is highly adaptable andwill cultivate in almost any soil. It has excellent remediation properties and has shown to be relatively consistent when itcomes to crop yields. The aim of this literature survey is to examine how hemp can be used to be considered asustainable energy crop in Sweden through database searches and interviews. Hemps characteristics as an energy cropand its remediation properties is evaluated and compared with other plants that are used in Sweden.

The municipal forests of Sala cover an area of 6 000 hectares, starting in the vicinity of the city and reaching north. At the same time as residents make abundant use of the areas closest to the community for outdoor activities and recreational purposes, the forest is of great economic value and also worth protecting for environmental reasons. These conditions make forestry in periurban woods more complex than conventional forestry, why a good understanding of the needs and demands on the forest and silviculture program is required. The purpose of this study is to depict the usage of the forests owned by the municipality of Sala, to set forth the common view of the silviculture program implemented by the municipality and to chart the expectations the community has on the forests and forestry of the future in the municipality of Sala. The survey part of this paper consists of the interviews of thirteen individuals representing nine interest groups. As expected the views of these individuals varied widely but some results were expressed by more or less all of them.

Feedback tools support electricity users within the Swedish residential sector to increase their knowledge of electricity and the electricity market as well as to become more aware of their electricity consumption, which in turn encourages a reduction and an increased flexibility of electricity use. The primary aim of this study is to identify and analyse how existing feedback tools can be improved, to ensure that they contribute efficiently to the achievement of the EU objectives congruent with a more sustainable energy system in 2030, emphasizing: greenhouse gas reduction, increased energy efficiency and an increased share of renewable energy. In order to reach the primary aim of this study, existing feedback tools have been identified and mapped and interviews with feedback tools providers have been conducted. The study is limited to three research areas: the practical functions of feedback tools, available technology and the use of feedback tools.The use of more efficient feedback tools will provide an increased success rate for energy management, which includes both behavioural changes and energy efficiency. According to the results from the interviews conducted for this study, an increased use and user frequency is important to utilise the energy management potential.

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.
