    Author : José Fiacro Castro Flores; Viktoria Martin; Bruno Lacarrière; Justin NingWei Chiu; Vittorio Verda; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; active thermal micro-grid; substation operation; performance assessment; distributed heat resources; chauffage urbain basse température; micro-réseaux de chaleur urbains actifs; fonctionnement de la sous-station; évaluation de la performance; sources de chaleur distribuées; lågtemperatur fjärrvärme; aktiv fjärrvärmemikronät; fjärrvärmecentral operation; prestationsbedömning; distribuerada värmekällor; Energy Technology; Energiteknik;

    Abstract : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. READ MORE

  4. 2. Energy renovation of multi-family buildings in Sweden : An evaluation of life cycle costs, indoor environment and primary energy use, and a comparison with constructing a new building

    Author : Lina La Fleur; Bahram Moshfegh; Patrik Rohdin; Andreas Koch; Linköpings universitet; []
    Keywords : ;

    Abstract : Residential buildings account for 27% of the final energy use in the European Union. In cold climates, space heating represents the largest proportion of the energy demand in residential buildings. By implementing energy efficiency measures (EEMs) in existing buildings, energy use can be significantly reduced. READ MORE

  5. 3. Energy Saving vs. Performance: Trade-offs in Optical Networks

    Author : Pawel Wiatr; Paolo Monti; Josep Solé-Pareta; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-efficiency; optical networks; RWA; side-effects; device reliability performance; network performance; operational cost; benefits; loss; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The energy consumption of communication networks is continuously growing. Many energy saving approaches have been proposed at the device, system, and network level. The most promising way to address this problem is to utilize photonic technologies as much as possible thanks to their low energy consumption per bit performance. READ MORE
