  1. 1. The impact on the energy system of heating demands in buildings A case study on district heating and electricity for heating in Falun, Sweden

    University dissertation from Västerås : Mälardalen university press

    Author : Moa Swing Gustafsson; Mälardalens högskola.; Högskolan Dalarna.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik; Energy; Forests and Built Environments; Energi; skog och byggd miljö;

    Abstract : Energy efficiency measures in buildings are considered to have great potential in order to reduce total energy consumption, and thus contribute to a reduced environmental impact and a better climate. In Sweden, however, the energy performance requirements for buildings are formulated in terms of bought energy, i.e. READ MORE

  2. 2. Heating of buildings from a system perspective

    University dissertation from Västerås : Mälardalen University

    Author : Moa Swing Gustafsson; Mälardalens högskola.; Högskolan Dalarna.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik; Energy and Built Environments; Energi och samhällsbyggnad;

    Abstract : Energy efficiency measures in buildings are considered to have great potential for reducing total energy use, and contribute to a reduced climate and environmental impact. In Sweden, however, there is a focus on bought energy, which does not always reflect the environmental and climate impact. READ MORE

  3. 3. Power System Oscillations - Detection, Estimation and Control

    University dissertation from Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Author : Morten Hemmingsson; Lund University.; Lunds universitet.; [2003]
