  1. 1. Energy-Efficient Retrofits on an Existing Home in Coimbra, Portugal : A dynamic assessment of environmental performance for future climate and energy mix scenarios

    University essay from KTH/Hållbara byggnader

    Author : Jordan Berman; [2022]
    Keywords : ;

    Abstract : This work introduces a method, called the dynamic building life cycle, to evaluate theenvironmental performance for residential renovation products. The method goes beyond a fullbuildinglife cycle by accounting for the changing dry bulb temperature and greenhouse gas (GHG)intensity over a 30-year period between 2020 and 2050. READ MORE

  2. 2. Surface haziness in chalcogenide glass

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Johan Berggren; William Hemberg; Isac Norberg; Elin Öqvist; Nina Johansson; [2022]
    Keywords : Chalcogenide; glass; surface; haziness;

    Abstract : This study seeks to determine the source of haziness in chalcogenide glasses, and to serve as a basis for further investigations. XPS, Raman spectroscopy and SEM was used to characterise the surface. Raman spectroscopy was used first and the results  indicated structural changes. READ MORE

  3. 3. A Root Sum of Squares approach for determining uncertainties in three different ways of characterizing a surface temperature for a Hot Box Setup : With added U-value calculations and incorporated uncertainties

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Tobias Wikman; [2022]
    Keywords : ;

    Abstract : The aim of this Master Thesis is to conduct an uncertainty analysis of three ways of characterizing a surface temperature of a Hot Box Setup (direct measurement, analytically calculatedand simulated). The purpose was to to provide insight into uncertainty analysis within Hot Box Setups. READ MORE

  4. 4. Investigating Surface Oxide Composition and Formation on Metallic Vibenite® Alloys

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Emil Monie; Nils Säfström; Yiping Deng; Axel Möllerberg; [2022]
    Keywords : Vibenite; oxide; oxide growth; surface refinement; surface smoothing; alloys; additive manufacturing; controlled oxides;

    Abstract : Oxide formation on metallic surfaces is a common phenomenon which occursnaturally or intently. Depending on the metallic oxide, they can be viewed as either nuisances or conveniences depending on the effects of the oxide. READ MORE

  5. 5. Economic and environmental optimization of deep energy renovation strategies for an office building in Sweden

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Eva Sauterleute; [2022]
    Keywords : Life Cycle Analysis LCA ; Global warming potential GWP ; Life Cycle Costs LCC ; Building Energy Simulation; Building Energy Renovation; Insulation Materials; OneclickLCA; IDA ICE; Livscykelanalys LCA ; global uppvärmningspotential GWP ; livscykelkostnader LCC ; energisimulering av byggnader; energirenovering av byggnader; isoleringsmaterial; One Click LCA; IDA ICE;

    Abstract : Energy efficiency of the building sector is a key strategy to achieve national climate goals in Sweden and other European countries. In this thesis, several renovation scenarios for a case study office building in Sweden are analysed and compared based on their energy performance, environmental impacts, and economic costs from a life cycle perspective.
