  1. 1. Development of life cycle cost model and analyses for railway switches and crossings

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Arne Nissen; Luleå tekniska universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Cost; RAMS; Maintenance Decision; Railway Infrastructure; Switches and Crossings; Industrial engineering and economy - Industrial organisation; administration and economics; Livscykelkostnad; RAMS; Underhållsbeslut; Järnväg; Spårväxlar; Industriell teknik och ekonomi - Industriell organisation; administration och ekonomi; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Infrastructure managers need to have a safe and available infrastructure, so that train operators can deliver a transport product at an affordable price. In the future, as traffic volume increases, higher utilisation of the existing capacity, less time for maintenance and fewer unplanned interruptions will be critical for meeting the ever increasing need of transport capacity.

  2. 2. Solar PV in prosumer energy systems A techno-economic analysis on sizing, integration, and risk

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Nelson Sommerfeldt; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrify everything; building energy systems; energy systems analysis; solar heat pump; investment analysis; Monte Carlo analysis; PVT; solar hybrid; Electrify everything; byggnadsenergisystem; energisystemanalys; solvärmepump; investeringsanalys; Monte Carlo analys; PVT; solhybrid; Energiteknik; Energy Technology; Planering och beslutsanalys; Planning and Decision Analysis;

    Abstract : In the transition towards a sustainable energy system, building mounted solar photovoltaics (PV) have unique benefits; they require no additional land and the energy is generated directly at load centers. Within residential buildings, multi-family homes (MFH) are particularly interesting because of the economies of scale and their greater potential for emissions reductions. READ MORE

    Abstract : The objective of this work is to explore ways of enhancing the overall lifetime quality, including cost and environmental efficiency, of Swedish concrete multi-dwelling buildings. The building and its characteristics, as well as the procedures for whole life optimisation, are addressed. READ MORE

  4. 4. Windows and blinds selection for enhancing subjective well-being

    University dissertation from Växjö : Linnaeus University Press

    Author : Elaheh Jalilzadehazhari; Linnéuniversitetet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subjective well-being; perceived control; controllability; analytical hierarchy process; non-dominated sorting genetic algorithm-II; Byggteknik; Civil engineering;

    Abstract : Earlier studies in the context of windows and blinds selection have mostly tried to increase the awareness regarding various effects of windows and blinds selection on subjective well-being, including their effect on visual comfort, thermal comfort, energy consumption and life cycle cost. However, the main problem is the potential conflicts between visual comfort, thermal comfort, energy consumption and life cycle cost. READ MORE

    Abstract : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. READ MORE
