  6. 4. Regulating energy performance of residential buildings in cold climate : a study of indicators, criteria, and evaluation methods

    Author : Ingrid Allard Stolterman; Thomas Olofsson; Gireesh Nair; Folke Björk; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy performance; building simulation; cold climate; energy use; indicators; evaluation methods; building regulations; residential buildings; energy measurements; performance gap; energy signature; sustainable development; hållbar utveckling; fysik; Physics;

    Abstract : Building energy performance has been important in Fennoscandia ever since the early vernacular houses, to combat the cold climate. Due to EU directive 2010/31/EU on the energy performance of buildings (EPBD recast), building energy performance has become even more relevant in northern Europe the last decade. READ MORE

  7. 5. Influences from Building Energy Efficiency Refurbishment on a Regional District Heating System

    Author : Tina Lidberg; Louise Ödlund; Thomas Olofsson; Urban Persson; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; energy efficiency; building refurbishment; greenhouse gases; primary energy; Fjärrvärme; energieffektivitet; byggnadsrenovering; växthusgaser; primärenergi; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola;

    Abstract : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reduce the greenhouse gas emissions caused by human activity and the primary energy use.To be able to evaluate how energy refurbishment influences the greenhouse gas emissions and the primary energy use a wider system perspective is needed that puts the building in its context.
