1. 6. Assessing impacts of climate change on the energy and hygrothermal performance of detached houses in Sweden

   Master-uppsats, Lunds universitet/Institutionen för bygg- och miljöteknologi; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Författare :Najma Habibullah; Busra Duran; [2023]
   Nyckelord :Detached houses; Hygrothermal performance; Energy performance; Extreme weather conditions; Climate change; Technology and Engineering;

   Sammanfattning : Climate change is one of the most significant challenges that building sector is confronting. For example, Climate change and associated extreme events are posing a significant challenge for the building sector. Buildings should be prepared to withstand the climate changes and extreme weather that will happen in the future. LÄS MER

4. 8. Numerical modeling of walls with micro encapsulated PCM

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Karl-Oskar Voutilainen; [2023]
   Nyckelord :PCM; phase change material; COMSOL Multiphysics;

   Sammanfattning : There is a renewed interest to use material as wood to construct large multi-storey buildings in Sweden, but lightweight material tends to increase the indoor temperature fluctuations during days with large changes in outdoor temperature. The problem can be resolved by integrating phase change material (PCM) in the construction. LÄS MER

5. 9. Potential benefits of implementing demand response into Vattenfall’s district cooling grid in Uppsala, Sweden

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

   Författare :Magdalena Guerrero Wretljung; [2023]
   Nyckelord :;

   Sammanfattning : Lately, there has been an increased cooling demand in Vattenfall’s district cooling (DC) network in Uppsala, Sweden. This especially occurs on warmer summer days, during so-called peak demand periods, where there is limited cooling capacity combined with limited distribution capacity in the network. LÄS MER

7. 10. Val av solavskärmning : Simuleringar för att identifiera lämplig solavskärmning för kontorshuset Vråken

   Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Max Berglund; [2023]
   Nyckelord :Solar shading; energy efficiency; office building; solar gain; cooling load; thermal comfort; IDA ICE; Solavskärmning; solskydd; energieffektivisering; kontorsbyggnad; solvärmelast; kyleffekt; termisk komfort; IDA ICE;

   Sammanfattning : The office building Vråken located in Västerås, Sweden, is soon to be renovated and improved solar shading is considered. In this project, five types of solar shading (zip screens, awnings, window film, built-in venetian blinds and roller blinds) were studied to find out their impact on the building's solar gain, cooling load and thermal comfort.
