    Sammanfattning : With the building sector accounting for around 40% of the total energy consumption in the EU, energy efficiency in buildings is and continues to be an important issue. Great progress has been made in reducing the energy consumption in new buildings, but the large stock of existing buildings with poor energy performance is probably an even more crucial area of focus.

    Sammanfattning : District heating and cooling are efficient systems for distributing heat and cold in urban areas. They are a key solution for planning future urban energy-efficient systems due to their high potential for integrating renewable energy sources. LÄS MER

  4. 8. Integration of Distributed Renewable Energy and Energy Storages in Buildings

    Författare :Yang Zhang; Jinyue Yan; Pietro Elia Campana; Anders Lundblad; Zhe Chen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; PV; Energy Storage; Operation; Optimization; Flexibility;

    Sammanfattning : Photovoltaic (PV) is a distributed renewable energy technology that is suitable for integration in buildings. PV reduces the electricity demands as well as the greenhouse gas emissions of buildings. LÄS MER

  5. 9. Utilization of a GSHP System in a DHC Network : modeling and optimization

    Författare :Anjan Rao Puttige; Thomas Olofsson; Ronny Östin; Staffan Andersson; Javed Saqib; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ground source heat pump; district heating and cooling; optimization; borehole heat exchanger; artificial neural network; hybrid model; field measurements; calibration; heat pumps; prosumer;

    Sammanfattning : The ground source heat pumps (GSHPs) of customers connected to the district heating and cooling (DHC) network can benefit both the customer and the energy company. However, operating the GSHP to minimize the cost of providing heating and cooling to the customer while ensuring the long-term stability of the ground temperature is a challenge. LÄS MER

  7. 10. A multi-sector framework for accelerating renewable energy deployment in power, transport and industry
