  1. 1. Integrating Waste Heat from Hydrogen Production Into District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fawzi Kayali; [2023]
    Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

  3. 2. Energy retrofitting effect on perceived indoor climate: A case study of Estonian multi-family buildings

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

    Författare :Kadri Reinumägi; [2023]
    Nyckelord :Indoor environment; Thermal comfort; Indoor Air Quality; Window airing habits; Energy renovation; Occupant survey; Technology and Engineering;

    Sammanfattning : Energy renovations are an important measure for achieving the European Union’s target of climate neutrality by 2050. To meet the EU goal, Estonia needs to fully renovate 14 000 multi-family buildings by that time, affecting the indoor environment conditions of a large number of people. LÄS MER

  4. 3. Energieffektivisering av ett kulturhistoriskt värdefullt timmerhus från slutet av 1600-talet

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Kulturvård

    Författare :Ida Wållberg; [2023]
    Nyckelord :byggnadsminne; kulturhistoriskt värdefull byggnad; energieffektivisering; energieffektiviseringsåtgärder; VIP-Energy;

    Sammanfattning : In order to achieve national energy policy goals, it is necessary to improve the energy efficiency in buildings. However, this can sometimes be in conflict with the objective of preserving cultural heritage. This study seeks to evaluate possible energy efficiency measures for a timber house constructed during the 1670s in Sala, Sweden. LÄS MER

  5. 4. Optimization of Thermal Comfort on Electric Buses : A Comprehensive Study on Passenger Satisfaction in Stockholm, Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ellinor Hambraeus; Maxwell Minotta Cuervo; [2023]
    Nyckelord :Electric bus; Bus temperature; Thermal comfort; Energy efficiency; Predicted Mean Vote; Equivalent temperature v; Elbuss; busstemperatur; termisk komfort; energieffektivisering; Predicted Mean Vote; Ekvivalent temperatur vii;

    Sammanfattning : The transition towards electrification in the bus sector is necessary to achieve the global climate goals and has gained significant traction in recent years. However, there are critical challenges associated with this transition, one of them being the absence of excess heat that traditional combustion engines provided to warm the bus cabin. LÄS MER

  7. 5. Inomhusklimat för simulering av hög boendetäthet i flerbostadshus

    Kandidat-uppsats, Lunds universitet/Avdelningen för Byggnadsfysik

    Författare :Linn Linderholt; Lovisa Persson; [2023]
    Nyckelord :Trångbodd; inomhusklimat; lägenhet; koldioxidproduktion; värmeproduktion; fuktproduktion; Technology and Engineering;

    Sammanfattning : In recent years overcrowding has decreased in European countries, but in Sweden overcrowding has increased, especially in the big cities. There is an ongoing problem in Swedish society regarding overcrowding that needs to be further investigated, and how these accommodations affect the design of the buildings they live in. LÄS MER
