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

    Author : Urban Persson; Sven Werner; Louise Trygg; Högskolan i Halmstad; []
    Keywords : District heating; energy efficiency; distribution capital cost; heat density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation; effective width;

    Abstract : 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. READ MORE

  3. 3. Management of Sustainability in Construction Works

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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.

  5. 5. Enhanced District Heating Technology : Maintaining Future System Feasibility

    Author : Helge Averfalk; Sven Werner; Urban Persson; Mei Gong; Patrick Lauenburg; Kerstin Sernhed; Per-Olof Johansson Kallioniemi; Louise Ödlund; Högskolan i Halmstad; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : When heat demand and high temperature heat supply gradually decreases in the future, then it will effect district heating systems ability to compete on the heat market. A good way to mitigate less district heating feasibility is to operate systems with lower temperature levels and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.
