  1. 21. Energy simulation and life cycle costs : estimation of a building's performance in the early design phase

    Författare :Jutta Schade; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : Sustainable development and the protection of the environment are key issues in our society today. The building stock in Europe accounts for over 40% of the final energy consumption, CO2 emissions and generation of waste. A large part of the life cycle performance is determined early. LÄS MER

  3. 22. Circular Business Models for Electric Vehicle Battery Second Life : Challenges, enablers, and preconditions from an ecosystem perspective

    Författare :Reza Toorajipour; Koteshwar Chirumalla; Fredrik Wallin; Vinit Parida; Patricia Van Loon; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric vehicle battery second life; circular business models; ecosystem; electric vehicles; EV batteries; circular business model innovation; circular economy; preconditions; second life configurations; battery second life; Innovation and Design; innovation och design;

    Sammanfattning : Sustainability has become a critical issue due to global warming, scarcity of resources, and the high costs of raw materials. It is vital to reconsider linear business models and value creation processes and transition towards circularity. The growth of the electric vehicles market is promising; however, it comes with a major downside. LÄS MER

  4. 23. Life cycle behaviour of concrete bridges : laboratory test and probabilistic evaluation

    Författare :Markus Bergström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The structural life for a concrete structure located in an environment where corrosion is promoted by humidity or chlorides from sea or de-icing salt could in general be described in the following manner. The structure is manufactured and is at that point considered to be intact. LÄS MER

  5. 24. Life cycle assessment of bridges, model development and case studies

    Författare :Guangli Du; Raid Karoumi; Håkan Sundquist; Gervásio Helena dos Santos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable construction; Life cycle assessment; LCA; Global warming; Bridge LCA; CO2 emissions; Cumulative energy demand; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : In recent decades, the environmental issues from the construction sector have attracted increasing attention from both the public and authorities. Notably, the bridge construction is responsible for considerable amount of energy and raw material consumptions. LÄS MER

  7. 25. Development and adaptation of a life cycle management system for constructed work

    Författare :Daniel Hallberg; Christer Sjöström; Nil Sahal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle management system; maintenance; predictability; service life performance analysis; Building engineering; Byggnadsteknik;

    Sammanfattning : Lifetime Engineering (or Life Cycle Engineering) is a technical approach for meeting the current objective of sustainable development. The approach is aimed to turn today’s reactive and short-term design, management and maintenance planning towards an optimised and long-term technical approach. LÄS MER
