  2. 2. 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.

  3. 3. Historical Urban Agriculture : Food Production and Access to Land in Swedish Towns before 1900

    Author : Annika Björklund; Mats Widgren; Johannes Renes; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban agriculture; urban history; urban geography; Sweden; town; food production; food consumption; Uppsala; historical geography; land allocation; cadastral maps; urban land-use; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Abstract : This doctoral thesis analyses the role of historical urban agriculture in a long-time perspective, through a combination of overarching surveys of Swedish towns and detailed studies of one town – Uppsala in east-central Sweden. The study shows how agricultural land – town land – of various sizes was donated to towns repeatedly during medieval times and in the 16th and 17th centuries. READ MORE
