  1. 16. Bending the Curve – the Role and Interplay of Municipal Energy Planning and Municipal Spatial Planning for Climate Change Mitigation in Sweden

    Författare :Vincent Wretling; Berit Balfors; Ulrika Gunnarsson-Östling; Christina Hörnberg; Catalina Turcu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local energy and climate planning; municipal comprehensive planning; wind power planning; climate policy integration; Strategic Environmental Assessment; institutional capacity building; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : The global climate is changing rapidly, which pronounces the need for imminently bending the curve of greenhouse gases emissions. The local authorities have been recognised as key actors in this decarbonisation, due to their wide-ranging responsibilities, including different mandates for local planning. LÄS MER

  3. 17. Prediction of power and energy use in dwellings : Addressing apects of thermal mass and occupant behaviour

    Författare :Victor Fransson; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadssimulering; Termisk massa; Värmetröghet; boendes beteende; hushållsel; varmvatten; building simulation; thermal mass; thermal inertia; occupant behaviour; household electricity; domestic hot water;

    Sammanfattning : Households are responsible for approximately 26 % of the annual energy use in the EU. Following the EU-directives regarding energy performance in buildings, international initiatives have been taken in Europe to help countries to define and include guidelines in their own building codes, for example, to establish the concept of zero energy buildings, ZEBs.

  4. 18. Anaerobic digestion of horse manure : renewable energy and plant nutrients in a systems perspective

    Författare :Åsa Hadin; Ola Eriksson; Karl Hillman; Nils Ryrholm; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Horse manure; horse keeping; anaerobic digestion; nutrient recycling; systems perspective; bedding; methane potential; feedstock; biogas; biofertilizer; Hästgödsel; hästhållning; rötning; näringsåterföring; systemperspektiv; strömaterial; metanpotential; biogassubstrat; biogas; biogödsel;

    Sammanfattning : In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. LÄS MER

  5. 19. Nanostructured Bulk Thermoelectrics : Scalable Fabrication Routes, Processing and Evaluation

    Författare :Mohsen Yakhshi Tafti; Muhammet S. Toprak; Gao Min; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermoelectric; Iron antimonide FeSb2 Skutterudite; Copper Selenide Cu2Se ; Spark Plasma Sintering SPS ; nanomaterial; Teknisk materialvetenskap; Materials Science and Engineering; Energy Technology; Energiteknik;

    Sammanfattning : Current fossil fuel based energy sources have a huge shortcoming when one discusses their efficiency. The conversion efficiency of fossil fuel-based technologies is less than 40% in best cases. LÄS MER

  7. 20. Renewable Heat on Demand : High-temperature thermal energy storage: a comprehensive study from material investigation to system analysis via innovative component design

    Författare :Silvia Trevisan; Björn Laumert; Rafael Guédez; Wujun Wang; Kurt Engelbrecht; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Sammanfattning : High-temperature thermal energy storage could enable widespread exploitation of renewable energy sources, providing the required energy flexibility. Technology and component development is needed to enhance the storage thermo-dynamic performance, and identify key design features. LÄS MER
