  1. 1. Energy renovation packages for the decarbonisation of Swedish multifamily buildings

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Bhavik Daya; Hugh Nolan; [2022]
    Nyckelord :Decarbonisation; Renovation; Multi-family homes; Life Cycle Assessment; Life Cycle Costing; Technology and Engineering;

    Sammanfattning : Sweden and Europe aim to be carbon neutral by 2045 and 2050 respectively. Upgrading the existing building stock has been identified as having great potential in assisting to realise these goals. LÄS MER

  3. 2. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations

    Master-uppsats,

    Författare :Manroop Bhattasali; [2022]
    Nyckelord :Catalytic converter; packaging mats; support mats; compression; friction; hyperelastic; hyperfoam; viscoelastic; canning; finite element;

    Sammanfattning : The increase of new and ever more stringent emission legislation has brought about with it a surge in the demand for more sustainable automotive solutions. This has particularly been the case for automobiles, including heavy-duty vehicles like trucks and buses, with internal combustion engines, which now require the design and manufacturing of more durable and reliable components.

  4. 3. Allowing more solar power connected to the grid, using thermal and ageing models of distribution transformers.

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Amena Khatun; [2021]
    Nyckelord :electric power distribution; solar power; renewable-electricity production; hosting capacity; distribution transformers; dynamic thermal rating; component ageing; component overloading.;

    Sammanfattning : Increasing amounts of solar power connected to the low-voltage network will adversely affect the performance of the network. The two impacts that will most often set the limit are overvoltage with the customers and overloading the distribution transformer. LÄS MER

  5. 4. Teknoekonomisk analys av fjärrvärmeledningar

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Jesper Eriksson; [2021]
    Nyckelord :energiteknik; fjärrvärme; fjärrvärmeledningar; teknoekonomisk analys; teknoekonomisk;

    Sammanfattning : Fjärrvärmeledningar levereras i olika isoleringsserier, där ökat serienummer ger en tjockare isolering. För enkelrör, fjärrvärmeledning med ett medierör, finns det fyra olika serier, och för dubbelrör, fjärrvärmeledning med två medierör, finns tre olika serier. LÄS MER

  7. 5. Development of grey-box models for simulating heating consumption in buildings : A study applying system identification methodology to a physics-based framework

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Zack Klockar; [2021]
    Nyckelord :System identification; heating; buildings; modelling; insulation; empirical modelling; ARX; OE; time-series; simulation; energy consumption; grey-box; black-box;

    Sammanfattning : This study models the energy used for heating in buildings by applying system identification methodology. The model development is grounded in physics to provide guidance and interpretability when evaluated. Time-series of heating demand, outdoor temperature, indoor temperature and solar irradiation are considered for the modelling purpose. LÄS MER
