    Sammanfattning : In the transition towards a sustainable energy system, building mounted solar photovoltaics (PV) have unique benefits; they require no additional land and the energy is generated directly at load centers. Within residential buildings, multi-family homes (MFH) are particularly interesting because of the economies of scale and their greater potential for emissions reductions. LÄS MER

  4. 3. Restructured district heating price models and their impact on district heating users

    Författare :Jingjing Song; Björn Karlsson; Fredrik Wallin; Hailong Li; Heimo Zinko; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; restructured price model; price model survey; pricing strategy; consumption profile; consumption pattern; alternative cost; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : District heating (DH) is considered to be an efficient, environmentally friendly and cost-effective method for providing heat to buildings, since electricity is usually co-generated in biomass fuelled combined heat and power (CHP) plants. This gives it an important role in the mitigation of climate change. LÄS MER

  5. 4. Thermal Interference Between Neighbouring Ground-Source Heat Pumps : Tools to Calcualte it and Solutions to Limit it

    Författare :Maria Letizia Fascì; Joachim Claesson; Alberto Lazzarotto; Loius Lamarche; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground source heat pumps; thermal interference; neighbouring geothermal boreholes; finite line source; mitigation strategies; Energiteknik; Energy Technology;

    Sammanfattning : Ground Source Heat Pumps (GSHPs) have emerged as a promising technology for decarbonization of the heating sector. However, their increasing prevalence in densely populated areas may lead to considerable changes in the ground temperature, which can ultimately lead to reduced performance of the systems. LÄS MER

  7. 5. 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

    Författare :Lina La Fleur; Bahram Moshfegh; Patrik Rohdin; Andreas Koch; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
