1. 1. Optimera energianvändningen i småhus : - en potentialstudie

   Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Författare :Tara Kadir; Jonas Lindhe; [2023]
   Nyckelord :direktverkande el; uppvärmning; småhus; energieffektivisering; effektivisering; optimering; BIM-Energy; värmepump; klimatskal;

   Sammanfattning : Med de nuvarande historiskt höga elpriserna och korta perioder av effektbrist är det mer relevant än någonsin att utforska möjligheterna att ersätta direktverkande el med alternativa system. Detta arbete undersöker, i samarbete med Länsstyrelsen i Halland, olika alternativa uppvärmningssystem som kan minska användningen av direktverkande el inom bostads- och servicesektorn, vilket utgör en betydande del av Sveriges totala elanvändning.

3. 2. HEAT CONSUMPTION OPTIMIZATION IN 4TH GENERATION DISTRICT HEATING : Study on utilizing low temperature heat sources and heat stored in a house by varying indoor temperature

   Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Framtidens energi

   Författare :Simon Karlsson; Farman Farman; [2023]
   Nyckelord :4th Generation District Heating; Heat Pumps; Thermal Energy Storage; Optimization; Low Temperature Heat Sources; Thermal Inertia;

   Sammanfattning : 4th generation district heating (4GDH) and varying the indoor temperature to store heat are both important concepts that can make it easier to implement more renewable energy and reduce costs of heating. This study looks at these concepts from a customer perspective using one building and looking at how energy can be stored and the performance of 4GDH. LÄS MER

4. 3. Global buckling of subsea pipelines with DEH cable

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Anders Meurk; [2022]
   Nyckelord :Solid Mechanics; Global Buckling; Subsea Pipelines; DEH cable; Hållfasthetslära; Global Buckling; Undervattensrörledningar; DEH kabel;

   Sammanfattning : Hydrates, wax, and other fluids forms in cold subsea pipelines which restrict flow of petroleum products during operation. This thesis analyses the global buckling behaviour of subsea pipelines with Direct Electric Heating cables (DEH) through a combination of analytical and FEM simulations. LÄS MER

5. 4. Energy efficiency measures in a typical Swedish single-family building from the 1960s

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

   Författare :Emanuel Larsson; Raffaello Ljungqvist Baldesi; [2022]
   Nyckelord :energy system; building; energy efficiency measures; storage; solar panels; electricity demand; heating demand; insulation;

   Sammanfattning : Many buildings built in the 1960s are inefficient when it comes to their energy use. A lot of them are also in need of renovating. Therefore, this project is aiming to investigate five different scenarios where the decrease in electricity demand is in focus. LÄS MER

7. 5. Energy Renovation: A case study of a multi-family house built during the Million program in Djursholm

   Master-uppsats, KTH/Energiteknik

   Författare :Adiltogtokh Bold; [2022]
   Nyckelord :Energy Renovation; Refurbishment; Energy Efficiency Measure; Direct-electric Heating; Multi-family House; Energirenovering; Renovering; Energieffektiviseringsåtgärd; Direktverkande El; Flerfamiljhus;

   Sammanfattning : Large share of Swedish building stock were built during 1940-1980 when people were not fully aware of the energy efficiency concept. Majority of the buildings that made energy declaration are in energy class E-G, which are considered as high energy consumption buildings with low energy performance, and only few buildings meet the Swedish requirements for near zero energy buildings which are in energy class A-C.
