  2. 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 : 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;

    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

  4. 2. Framing the water and sanitation challenge : A history of urban water supply and sanitation in Ghana 1909 - 2005

    Author : Anna Bohman; Lena Andersson-Skog; Urban Strandberg; Björn-Ola Linnér; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ghana; urban water supply; sanitation; institutional change; policy development; frames; private sector participation; economic history; Economic history; Ekonomisk historia; ekonomisk historia; Economic History;

    Abstract : This thesis analyses the development of urban water supply and sanitation services in Ghana from 1909 to 2005.  Special focus is put on institutional arrangements with regard to networked, large scale and centrally managed water and sewerage services. READ MORE

  5. 3. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt

    Author : Arya Vijayan; Maria Viklander; Helene Österlund; Göran Blomqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban snow; Traffic pollution; Suspended solids; Metals; PAHs; Tire and Road wear Particles T RWPs ; Microplastics MPs ; Size fractionation; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Abstract : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.

  6. 4. The Urban Farmer : Osteoarchaeological Analysis of Skeletons from Medieval Sigtuna Interpreted in a Socioeconomic Perspective

    Author : Anna Kjellström; Ebba During; Jan Storå; Sten Tesch; Berit Sellevold; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; urbanization; health index; Middle Ages; sex distribution; age distribution; dietary patterns; Archaeology subjects; Arkeologiämnen; arkeologi; Archaeology;

    Abstract : At the end of the 10th century the first Swedish town Sigtuna was founded, which can be recognized as the beginning of urbanization in the Mälaren valley. Christianity was growing strong and the administrative power was probably concentrated to a few magnates gathered around a king. READ MORE

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

    Author : Urban Persson; Sven Werner; Lars J. Nilsson; Sweden Gothenburg Chalmers University of Technology; []
    Keywords : 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;

    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.
