  1. 1. Energy analysis for sustainable mega-cities

    Författare :Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.

  3. 2. From waste problem to renewable energy resource : exploring horse manure as feedstock for anaerobic digestion

    Författare :Åsa Hadin; Ola Norrman Eriksson; Karl Hillman; Nils Ryrholm; Jaana Sorvari; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; horse manure; environmental systems analysis; energy systems; renewable energy; environmental impact; anaerobic digestion; biogas; biofertilizer; systems perspective; bedding; incineration; composting; horse manure utilization;

    Sammanfattning : A sustainable energy system requires, according to energy policies, reduced emissions of greenhouse gases, increased ratio of renewable sources of energy and more efficient use of energy. Horse manure could be regarded as waste, but also as a resource for renewable energy and plant nutrients. LÄS MER

  4. 3. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

    Författare :Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

    Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER

  5. 4. Future District Heating Interactions – Modelling Impacts of Industrial Excess Heat Utilisation and Energy Efficient Buildings

    Författare :Akram Sandvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fourth generation district heating; TIMES; waste heat; urban planning.; dynamic energy system modelling; MARKAL; passive houses; low-energy buildings; excess heat;

    Sammanfattning : International goals for climate change mitigation plus energy security targets could be met cost-effectively by interactions between different parts of energy systems. The fourth generation of the district heating systems concept was developed as an attempt to accelerate district heating (DH) systems’ interactions with other energy systems. LÄS MER

  7. 5. Heat demand profiles of buildings' energy conservation measures and their impact on renewable and resource efficient district heating systems

    Författare :Lukas Lundström; Erik Dahlquist; Fredrik Wallin; Björn Karlsson; Jan Akander; Sven Werner; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; energy conservation; weather normalisation; typical meteorological year; building energy simulation; system analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Increased energy performance of the building stock of European Union is seen as an important measure towards mitigating climate change, increasing resource utilisation efficiency and energy supply security. Whether to improve the supply-side, the demand-side or both is an open issue. LÄS MER
