  1. 1. Advancing the life cycle energy optimisation methodology

    Författare :Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Tracy Bhamra; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; HUMANITIES; HUMANIORA; TEKNIK OCH TEKNOLOGIER; HUMANIORA; ENGINEERING AND TECHNOLOGY; HUMANITIES; life cycle energy; vehicle design; optimisation; functional conflicts; livscykelenergi; fordonsdesign; optimering; tvär-funktionella konflikter; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The Life Cycle Energy Optimisation (LCEO) methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle, while complying with a set of functional constraints. This effectively balances trade-offs, and therewith avoids sub-optimal shifting between the energy demand for the cradle-to-production of materials, operation of the vehicle, and end-of-life phases.

  2. 2. Life-Cycle Costing : Applications and Implementations in Bridge Investment and Management

    Författare :Mohammed Safi; Raid Karoumi; Håkan Sundquist; Jan-Eric Nilsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Bridge; Cost; Life Cycle Cost Analysis; Procurement; Investment; Management;

    Sammanfattning : A well-maintained bridge infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements sustainably and cost-effectively is challenging. Bridge investment and management decisions generally involve selection from multiple alternatives. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; livslängd; materialval; energianvändning; inomhusklimat; livscykelanalyser; livscykelkostnader; hållbar utveckling; Sustainable construction; Building construction; Service life design; Multiple Attribute Decision Analysis; Energy efficient buildings; Life Cycle Assessment; projektering; betongkonstruktioner; flerbostadshus; Byggnadsteknik; Integrated life cycle design; Life Cycle Costing;

    Sammanfattning : 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. LÄS MER

  4. 4. Life Cycle Costing in Road Planning and Management : A Case Study on Collision-free Roads

    Författare :Jonas Wennström; Håkan Sundquist; Tommy Edeskär; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collision-free road; design; infrastructure; investment; life cycle costing; life cycle cost analysis; maintenance; management; operation; planning; road; sustainability;

    Sammanfattning : Construction of infrastructure does not only mean large capital investments but also future costs to operate and maintain these assets. Decision making in planning and design of roads will impact the need of future operation and maintenance activities. LÄS MER

  5. 5. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers

    Författare :Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; road maintenance; road management; road planning; road design; life-cycle cost; road barrier; guardrails; cable barrier; road traffic injuries; barrier collisions and barrier repair costs.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; barrier collisions and barrier repair costs; Vägprojektering för minskade drift- och underhållskostnader;

    Sammanfattning : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. LÄS MER
