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

    Detta är en avhandling från Gothenburg : Chalmers University of Technology

    Författare :Urban Persson; Högskolan i Halmstad.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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; district heating;

    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

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

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Urban Persson; [2015]
    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.

  3. 3. Compact sprawl Exploring public open space and contradictions in urban density

    Detta är en avhandling från Stockholm : KTH

    Författare :Alexander Ståhle; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spatial morphology; Urban design; Public open space; Urban density; Landscape planning; TECHNOLOGY Civil engineering and architecture Architecture and architectural conservation and restoration Architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Arkitektur och bebyggelsevård Arkitektur;

    Sammanfattning : Twentieth century urbanization has left a tremendous footprint on the globe. It is generally speaking a spread out fragmented suburban and exurban landscape continuously growing according to what has been called sprawl-like development, increasing energy and automobile dependency, challenging urban sustainability.

  4. 4. Planning for emergence: Confronting rule-based and design-based urban development

    Detta är en avhandling från Stockholm : KTH

    Författare :Hye Kyung Lim; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; density; compact city; rule-based approach; diversity; design-based approach; urban resilience; planning by coding; emergent urban form;

    Sammanfattning : Increasing urban populations, climate changes, financial instability, global conflicts, depletion of resources, and increasing land consumption all contribute to the complex and unpredictable urban challenges we are facing today. A compact urban form is promoted by global and local policies, and research has shown the benefits of dense and diverse properties for their capacity to provide complex responses to complex challenges.

  5. 5. Planning for Solar Buildings in Urban Environments

    Detta är en avhandling från Lund University

    Författare :Jouri Kanters; Lunds universitet.; Lund University.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architecture; design tool; design process; solar energy; urban planning; photovoltaics; solar thermal; building integration; density; net zero energy buildings; interviews; parametric studies; action research;

    Sammanfattning : Popular Abstract in Swedish Solenergi kommer att vara en av de viktigaste miljövänliga energikällorna i framtiden, vilket innebär ökat antal solpaneler (för el och värme) som integreras i våra hus men också som fristående produktionsanläggningar. När man planerar framtida hus och stadsdelar är det viktigt att skapa de bästa förutsättningarna för solenergi eftersom hus och stadsdelar finns kvar i flera generationer. LÄS MER
