  1. 1. The influence of spatial variations in rain intensity for cloudburst modelling : a case study of the Gävle cloudburst

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Fanny Jeppsson Stahl; [2022]
    Nyckelord :Flood modelling; pluvial flooding; spatial variations in rain intensity; design storms; MIKE 21 Flow Model FM; 2D hydraulic modelling; Skyfallsmodellering; pluviala översvämningar; spatiala variationer i regnintensitet; typregn; MIKE 21 Flow Model FM;

    Sammanfattning : With an intensification of heavy rain events in a changing climate and a rapid urbanization the risk for pluvial flooding is increasing in our societies. Pluvial flooding, which is formed when the rainfall rate exceeds the infiltration or drainage rate, can occur rapidly and cause great damages, large economic losses and possibly risk human lives.

  3. 2. A comparative Life Cycle Assessment (LCA) study of centralized and decentralized wastewater heat recovery in Stockholm, Sweden

    Master-uppsats, KTH/Energiteknik

    Författare :Deniz Pektas; [2021]
    Nyckelord :;

    Sammanfattning : The cities bear a large role in the climate crisis. However, this also means that they have a big potential in the transition towards sustainable communities and a sustainable world. Up to 90 % of energy use within the urban water cycle is allocated to hot water heating for end users. LÄS MER

  4. 3. Energy audit in Ockelbo healthcare center

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Pedro De Wit; [2020]
    Nyckelord :energy audit; heat balance; energy use; greenhouse gases emissions; improvement measures; efficiency;

    Sammanfattning : As the world is becoming aware of the impact of global warming reducing greenhouse gases emissions presents itself as a fundamental issue in order to avoid the environmental collapse and its negative consequences. One of the key points of this challenge it’s to make a responsable use of the energy. LÄS MER

  5. 4. Energikartläggning av Hjoggböleskolan : med investeringskalkyl för installation av bergvärmepump

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

    Författare :Martin Lindgren; [2020]
    Nyckelord :Energiteknik; Energi; Energikartläggning; Bergvärmepump; Investeringskalkyl;

    Sammanfattning : In this work, an energy survey has been carried out at Hjoggböleskolan and an investment calculation for an installation of a geothermal heat pump at the same school on behalf of Skellefteå Municipality. The energy survey carried out was done based on information from existing drawings given by Skellefteå Municipality and site visits to the school. LÄS MER

  7. 5. The impact from varying wind parameters and climate zones on building energy use : A case study on two multi-family buildings in Sweden using building energy simulation

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Karthickraj Tamilvanan; Sai Kiran Mathipadi; [2020]
    Nyckelord :Building energy simulation; Building energy use; IDA-ICE; Wind effects; wind speed;

    Sammanfattning : Globally, buildings utilize 35 % of the final energy use and contribute to approximately one-third of CO2 emissions. Hence, reducing the energy use of buildings contributes to a large amount of CO2 emissions to be decreased. LÄS MER
