  1. 6. A Statistical Approach to Estimate Thermal Performance and Energy Renovation of Multifamily Buildings : Case study on a Swedish city district

    Författare :Martin Eriksson; Bahram Moshfegh; Shahnaz Amiri; Jan Akander; Sasan Sadrizadeh; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy signature; multifamily building; district heating; energy renovation; simulation; heat loss coefficient; balance temperature; base load; energisignatur; flerbostadshus; fjärrvärme; energirenovering; simulering; värmeförlustkoefficient; balanstemperatur; baslast; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Several climate and energy goals have been set in the European Union, one of them being to increase energy efficiency. In Sweden, a large potential for increased energy efficiency lies in the residential and service sectors, which account for about 40% of total energy use. LÄS MER

  3. 7. Evaluating the utilisation of industrial excess heat from an energy systems perspective

    Författare :Igor Cruz; Magnus Wallén; Mats Söderström; Maria Johansson; Danica Djuric Ilic; Johanna Mossberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial excess heat; Waste heat; Heat recovery; Greenhouse gas emissions;

    Sammanfattning : Sweden aims to achieve climate neutrality by 2045. The need to immediately reduce greenhouse gas emissions in order to achieve climate targets affects industry directly. The pulp and paper sector is responsible for more than 50% of industrial energy use in Sweden. LÄS MER

  4. 8. Electrification of Road Transportation - Implications for the Electricity System

    Författare :Maria Taljegård; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway E39; CO2 emissions; electric vehicle; electric road systems; energy system modelling; variable renewable electricity;

    Sammanfattning : It is incumbent upon the transport sector to reduce its CO2 emissions by replacing fossil fuels with low-carbon alternatives. Suggested strategies include electrification of the road transport sector through the use of electric vehicles (EVs) with static charging, electric road systems (ERS), and the use of electricity to produce fuels.

  5. 9. Tracking Emissions Reductions and Energy Efficiency in the Steel Industry

    Författare :Johannes Morfeldt; Semida Silveira; Wolfgang Eichhammer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; greenhouse gas emissions reductions; indicators; iron and steel industry; systems analysis; energieffektivitet; växthusgasutsläppsminskning; indikatorer; järn- och stålbranschen; systemanalys; Energy Technology; Energiteknik;

    Sammanfattning : The iron and steel industry has become increasingly globalised. Market conditions are also changing and de-carbonisation of production is challenging.The objective of this thesis is to assess how energy efficiency and greenhouse gas emissions reductions can be promoted and effectively monitored in the steel industry.

  7. 10. National Energy System Modelling of Industry : Optimising the Transition Towards Carbon Neutrality

    Författare :Erik Sandberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Peter Lund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Industry is a major user of energy and emitter of fossil CO2. At the same time, Sweden targets net-zero greenhouse gas emissions by 2045. Current policies to reduce greenhouse gas emissions and mitigate climate change, and the transition of the energy system it requires, will present major challenges for industry. LÄS MER
