1. 26. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Gabriel Macêdo; [2020]
   Keywords : material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

   Abstract : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. READ MORE

3. 27. Demolish or Refurbish an Existing Building? : A bachelor thesis on the climate impact of different methods of renewing a building

   University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Author : Desirée Lennermark; Victoria Bjellerup; Lisa Bäckström; Lisen Wedman; [2020]
   Keywords : Building; Demolish; Refurbish; renovation; Environmental impacts; Embodied carbon; Energy use; LCA; Life cycle assessment;

   Abstract : The purpose of this bachelor thesis is to evaluate different alternatives of renewal regarding an already existing building. The case study building is located in the Ulleråker area in Uppsala, Sweden and is an old mental hospital building from the 1950’s which Uppsala Municipality wishes to restore as part of a bigger investment in the neighborhood.

4. 28. Conditioned atria in the built environment - A possible solution for unsustainable urbanization and climate change in Nordic climates?

   University essay from Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

   Author : Lucas Cupello de Vasconcellos; [2020]
   Keywords : Conditioned atrium; built environment; final energy consumption; energy efficiency; indoor gardens; green spaces; Internationella Engelska Skolan Östersund; International English School Östersund; temperate climates; Nordic climates; weather damage; refurbishment; repair; impact; environmental impact;

   Abstract : The aim of the research is to explore the differences in final energy consumption and environmental impact of the construction materials related to the atrium alternative and a business-as-usual and evaluate how to improve thermal properties of old buildings that require renovations to fit thermal efficiency standards and comfort in operational conditions while reducing the overall impact of the projects. Results show that for the low-rise atrium most of the parameters related to the final energy demands and environmental impacts of the atrium construction materials are proportional and linear to the increase of the glazing area size.

5. 29. Climate Change Mitigation Measures of Load-Bearing Structure - A comparison of alternative structural designs using Life Cycle Assessment

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

   Author : Mirass Jalil; [2020]
   Keywords : Life Cycle Assessment; LCA; Load-Bearing Structure; Livscykelanalys; Byggnadsstomme; stomalternativ; structural engineering; span length; cross-section depth; precast concrete slab; in-situ concrete slab.; Technology and Engineering;

   Abstract : I mars 2015 nådde den globalt genomsnittliga koldioxidhalten 400 ppm för första gången på tre miljoner år. Därför satte den svenska regeringen, år 2017, upp målet att Sverige ska vara klimatneutralt år 2045. READ MORE

6. 30. Pointing in circles is not a way to circular economy : Barriers to a circular use of ICT products from a user organisation’s perspective

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Catja Carlson; Sara Österberg; [2019]
   Keywords : Circular economy; Sustainability; ICT products; Circular electronics; Reuse; Refurbishment; Barriers to circular economy; Management; Cirkulär ekonomi; Hållbarhet; ICT-produkter; Cirkulär elektronik; Återanvändning; Rekonditionering; Barriärer för en cirkulär ekonomi; Ledning;

   Abstract : The circular economy, in which products, materials and resources circle back into the system rather than ending up as waste, offers the possibility to decouple economic growth from environmental degradation. For the sector of information and communication technologies (ICT), where the products contain a wide range of critical raw materials and have a large environmental impact during their manufacturing phase, a shift from today’s linear consumption is especially important.
