  1. 1. Realise the Potential! : Cost Effective and Energy Efficient District Heating in European Urban Areas

    Författare :Urban Persson; Sven Werner; Louise Trygg; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; District heating; energy efficiency; distribution capital cost; heat density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation; effective width;

    Sammanfattning : The Member States of EU27 need to accelerate the integration of energy efficient technology solutions to reach the 20% energy efficiency target set for 2020. At current pace, projections indicate that only half of expected primary energy reductions will be reached. LÄS MER

  3. 2. Att styra ett hållbart byggande - En definition av och en styrmodell för ett hållbart byggande

    Författare :Urban Persson; Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable construction; construction management model; styrmodell; Hållbart byggande;

    Sammanfattning : A large part of the Earth’s turnover of resources is associated with buildings and building construction. There is therefore a complex relationship to be taken into consideration when realizing construction projects, since economic and social aspects also affect individual people. LÄS MER

  4. 3. Management of Sustainability in Construction Works

    Författare :Urban Persson; Byggproduktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction works; assessment model; sustainability; Management;

    Sammanfattning : The present global environmental condition is a consequence of the increasing consumption of natural resources whose depletion exceeds what is physically possible to sustain in the long term. The construction sector is a considerable contributor to this resource depletion and sustainability is adopted in the form of the theory of ecological modernization. LÄS MER

  5. 4. District heating in future Europe : Modelling expansion potentials and mapping heat synergy regions

    Författare :Urban Persson; Sven Werner; Lars J. Nilsson; Sweden Gothenburg Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

    Sammanfattning : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.

  7. 5. Influences from Building Energy Efficiency Refurbishment on a Regional District Heating System

    Författare :Tina Lidberg; Louise Ödlund; Thomas Olofsson; Urban Persson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; energy efficiency; building refurbishment; greenhouse gases; primary energy; Fjärrvärme; energieffektivitet; byggnadsrenovering; växthusgaser; primärenergi; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola;

    Sammanfattning : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reduce the greenhouse gas emissions caused by human activity and the primary energy use.To be able to evaluate how energy refurbishment influences the greenhouse gas emissions and the primary energy use a wider system perspective is needed that puts the building in its context.
