    Sammanfattning : Energy use in the European Union is increasing. At the same time, it is estimated that by the year 2050 most of the EU population will be living in currently existing buildings. Some of these buildings are or will be in need of renovation, and they have identified a target to reduce overall energy use. LÄS MER

  3. 2. A methodology to assess impacts of energy efficient renovation : a Swedish case study

    Författare :Ricardo Ramirez Villegas; Ola Eriksson; Thomas Olofsson; Sofia Lidelöw; Högskolan i Gävle; []

    Sammanfattning : The European Union aims to reduce energy use and CO2-emissions by 40 % by the year 2030. The building sector has been identified as having a great potential to reduce emission of CO2 by increasing its energy efficiency. LÄS MER

  4. 3. Energy Efficient Renovation Strategies for Swedish and Other European Residential and Office Buildings

    Författare :Marcus Gustafsson; Sture Holmberg; Jonn Are Myhren; Chris Bales; Jarek Kurnitski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; renovation; low-temperature heating; air heat recovery; district heating; heat pump; Energieffektivitet; renovering; lågtemperaturuppvärmning; värmeåtervinning; fjärrvärme; värmepump; Byggvetenskap; Civil and Architectural Engineering; Energy and Built Environments;

    Sammanfattning : The high energy use in the European building stock is attributable to the large share of old buildings with poor energy performance. Energy renovation of buildings is therefore vital in the work towards energy efficiency and reduced environmental impact in the EU. LÄS MER

  5. 4. Aerogel-based plasters for renovation of buildings in Sweden: Identification of possibilities, information deficiencies and challenges

    Författare :Ali Naman Karim; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compatibility; durability; plaster; mechanical; render; energy efficient retrofitting; hygrothermal; renovation; listed building; Aerogel;

    Sammanfattning : Aerogel-based plasters are a class of high energy efficient wall finishes with declared thermal conductivities around 30-50 mW/(m∙K). Aerogel-based plasters are promising alternatives to substitute conventional insulation materials when renovating uninsulated building envelopes. LÄS MER

  7. 5. Making sense of and managing energy targets in public construction-client organisations

    Författare :Kjerstin Ludvig; Chalmers tekniska högskola; []

    Sammanfattning : The built environment is acknowledged as having a large potential to reduce society’s energy use and has a major responsibility to contribute to mitigating climate change. In Sweden, it has been suggested that public organisations should take a leading role, and serve as good examples in the development of energy-efficient building. LÄS MER
