    Sammanfattning : The European policy focus on smart grids implies their development as an indispensable part of the future power system. However, the definition of a smart grid is broad and vague, and the actual implementation of a smart grid can differ significantly, depending on the stakeholders involved. LÄS MER

  5. 29. Energy use in multi-family dwellings : measurements and methods of analysis

    Författare :Hans Bagge; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy use; multi-family dwellings; district heating; space heating; domestic hot water heating; common electricity; household electricity; solar heat gains.;

    Sammanfattning : In 2001, multi-family dwellings were built at nine properties in Västra hamnen, Malmö, Sweden. Several well known Swedish architects were involved in designing the buildings, hence they reflect modern architecture. Prior to the inauguration, the buildings were displayed at the international housing exhibition Bo01. LÄS MER

  7. 30. Energy Services in Sweden - Customer Relations towards Increased Sustainability

    Författare :Kerstin Sernhed; Energihushållning; []
    Nyckelord :demand-side management; district heating; electricity; Customer relations; district-heating marketing strategies; load management; feedback;

    Sammanfattning : Energy use and supply are evident issues to consider for a sustainable development, where the economic, social and environmental aspects are all important. In large grid-bound systems, the supply of energy is usually a rather invisible activity and the contacts between household custo-mers and utilities are sometimes only repre-sented through the energy bill.
