1. 6. Fönsterareans klimatpåverkan : Jämförelse av koldioxidutsläpp från material- och energianvändning när fönsterarea varieras

   M1-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

   Författare :Philip Möller; Erik Elfstrand; [2023]
   Nyckelord :;

   Sammanfattning : Right now, the world is facing a challenge of reducing carbon emissions. Existing buildings account for one-third of the world's carbon emissions. The construction and real estate sector in Sweden is facing the challenge of combining a high rate of construction with demands on reduced climate emissions. LÄS MER

3. 7. 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

4. 8. Techno-economic analysis and simulation of low temperature district heating networks

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

   Författare :Ilia Iarkov; [2023]
   Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

   Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

5. 9. Återbruk av byggnadsmaterial : En litteraturstudie om utmaningar som idag hindrar användningen av återbrukade byggnadsmaterial

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

   Nyckelord :Reuse; deconstruction; obstacles; challenges; technical; economic; environmental;

   Sammanfattning : Purpose: This study aims to identify obstacles and challenges that prevent the reuse of building materials and bring forth possible solutions. But also to examine the technical-, economic- and environmental advantages and disadvantages of using reused building materials. LÄS MER

7. 10. Green and Sustainable JavaScript : a study into the impact of framework usage

   Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik

   Författare :Malin Wadholm; [2023]
   Nyckelord :sustainability; web development; JavaScript; carbon emissions; performance;

   Sammanfattning : Background. Using JavaScript frameworks has become a popular approach for developing web applications. However, the large bundle sizes associated with framework usage may not always be necessary from a sustainability standpoint. Utilizing a framework or not could potentially impact a web application’s performance and carbon emissions. LÄS MER
