  2. 11. Utilizing solar energy for anti-icing road surfaces using hydronic heating pavement with low temperature

    Author : Raheb Mirzanamadi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar energy; asphalt concrete; ground heat exchanger; anti-icing; optimization;

    Abstract : During summer, the surface temperature of an asphalt road pavement can rise up to 70°C due to absorbed solar radiation. The high temperature degrades the performance of the asphalt concrete by accelerating the thermal oxidation and plastic deformation, especially under heavy traffic loads. READ MORE

  4. 12. Seasonal snow storage for space and process cooling

    Author : Kjell Skogsberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : The world’s cooling demand has increased considerably during the last decades due to increased population, industrialisation, comfort demands, electronic equipment usage and new building technologies. Conventional cooling is often produced by electrically driven devices. READ MORE

  5. 13. Evolution of Future Heating Systems - Modeling of an Expanding City Using a Dynamic Systems Approach

    Author : Karl Vilén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heating system; Thermal energy storage; Low-heat-demand housing; Dynamic energy systems modeling; Housing; District heating; Climate policy; TIMES;

    Abstract : Reducing greenhouse gas emissions is central to meeting climate change mitigation targets. Since the energy sector is one of the largest greenhouse gas emitters, it is essential that all the actors within the energy sector reduce their respective emissions. READ MORE

  6. 14. Novel approaches in modeling of soil carbon : Upscaling theories and energetics

    Author : Arjun Chakrawal; Stefano Manzoni; Hyun-Seob Song; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Microorganisms; soil C cycling; spatial heterogeneity; energetics; thermodynamics; microbial metabolism; calorespirometric ratio; microbial traits; heat dissipation; microscale; Physical Geography; naturgeografi;

    Abstract : Soils contain more carbon (C) than terrestrial (above ground) and atmospheric carbon combined. Mismanagement of soil C could lead to increased greenhouse gas emissions, whereas practices leading to increased C storage would help mitigate climate change while improving soil fertility and ecological functions.

  7. 15. Low energy buildings equipped with heat pumps for high self-consumption of photovoltaic electricity

    Author : Richard Thygesen; Björn Karlsson; Robert Öman; Joakim Widén; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The building sector is a prioritized area in the European Unions (EU) ambition to reduce the total final energy use by 20 %; lower the emission of greenhouse gases by 20 % and using energy 20 % more efficient by 2020. The residential sector in the European Union accounts for 27% of the un-ion’s final energy use and the EU views decentralized energy generation and heat pumps as important measures in reducing the energy demand in the building sector.
