  1. 36. Promotion of sustainable renovation in the built environment : An early stage techno-economic approach

    Författare :Navid Gohardani; Folke Björk; Bo-Göran Hellers; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refurbishment; retrofitting; renovation; energy consumption; Vacuum Insulation Panels; ACES;

    Sammanfattning : According to the Swedish Government's set targets for energy use and environmental quality imposed by the European Union, the total energy per heated unit area in residential and commercial buildings will have to be decreased by 20% in 2020 and 50% by 2050 in relation to the annual consumption of 1995. The building sector should additionally be completely independent of fossil fuels for energy usage, with the increasing sector of renewable energy continuously growing until 2020. LÄS MER

  3. 37. Light Design : Outdoor Urban Public Places : - Urban Lighting: Design and Technologies -

    Författare :José Nuno Sampaio; Björn-Erik Erlandsson; Izael Pereira Da Silva; KTH; []
    Nyckelord :Light-based Technologies and Design; Energy Technology; Energiteknik;

    Sammanfattning : Most of the present time outdoor lighting investments seem to be focused on road and automotive traffic facilities or oriented toward safety, security and efficiency. We can identify this in many of the world cities, as a globally spread common practice, where lighting is still highly perceived as a pure matter of quantities’ distribution.

  4. 38. Evaluating System Consequences of Energy Co-operation between Industries and Utilities

    Författare :Inger-Lise Svensson; Bahram Moshfegh; Thore Berntsson; Kornelis Blok; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Energy conservation, energy efficiency measures, and energy carrier conversion within the industry are extremely important issues in order to deal with energy resource depletion and the threats from global warming. In Swedish industry there is potential for reductions of carbon dioxide emissions and resource use through utilization of excess heat and conversion of compression cooling to other cooling technologies using less electricity.

  5. 39. Using exergy and optimization models to improve industrial energy systems towards sustainability

    Författare :Mei Gong; Jinyue Yan; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : With finite natural resources and large energy demands in the world, a sustainable development approach becomes increasingly important in the improvement of energy systems. The concept of sustainability is examined with relation to exergy flows on the earth. The present industrial society is obviously not sustainable. LÄS MER

  7. 40. Green Buildings : Exploring performance and thresholds
