  1. 1. Elbesparing med pelletkaminer och solvärme i direktelvärmda småhus

    Författare :Tomas Persson; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; Pellets; Kaminer; Småhus; uppvärmning; Solvärme; Elvärme; konvertering; Biobränsle; Systemlösningar;

    Sammanfattning : The aim of this study was to investigate how electricallyheated houses can be converted to using wood pellet and solarheating. There are a large number of wood pellet stoves on themarket. Many stoves have a water jacket, which gives anopportunity to distribute the heat to domestic hot water and aradiator heating system.

  3. 2. Efficient heat supply and use from an energy-system and climate perspective

    Författare :Maria Danestig; Björn G. Karlsson; Dag Henning; Erik Dotzauer; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The aim of this thesis is to illustrate whether the heat demand in district heating systems can be seen as a resource that enables efficient energy utilization, how this can be achieved and to discuss consequences of this assumption. Based on the answers to posed research questions and on the studies included in this thesis, it is concluded that the hypothesis “A common system approach for energy supply and heat demand will show climate and economic efficient solutions” is true.

  4. 3. Investigation into sustainable energy systems in Nordic municipalities

    Författare :Robert Fischer; Andrea Toffolo; Erik Elfgren; Danica Djuric Ilic; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy sources; Nordic municipalities; municipal energy system; electrified transport; biofuels; multi-objective optimization; EnergyPLAN; Energiteknik; Energy Engineering;

    Sammanfattning : Municipal energy systems in Nordic environments face multiple challenges: the cold climate, large-scale industries, a high share of electric heating and long distances drive energy consumption. While actions on the demand side minimize energy use, decarbonization efforts in mining, industries, the heating and the transport sector can increase the consumption of electricity and biofuels.

  5. 4. Energy Efficiency in buildings in the Baltic states and the Nordic countries

    Författare :Xiaoying Li; Jonas Björnerstedt; Mats Bergman; Xiang Lin; Robert Lundmark; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy efficiency; building regulation; multi-apartment buildings; retrofit; energy performance gap; housing management; energy price inflation; inflation expectations; energieffektivitet; byggreglering; flerbostadshus; renovering; energiprestandagap; bostadsförvaltning; energiprisinflation; inflationsförväntningar; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Improving energy efficiency in buildings is widely viewed as a cost-effective way of achieving climate and energy goals. The Energy Performance of Buildings Directive (EPBD) aims to enhance the energy performance of new buildings and increase the renovation rate of energy-inefficient older buildings in the European Union.
