  1. 1. Mathematical modelling of jointed rock masses

    Författare :Thomas Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : In this thesis, a theoretical model of the mechanical behaviour of jointed rock masses is developed. An equivalent material approach is used to formulate the constitutive equations, where the structural components, intact rock and joints are assigned continuous material properties. LÄS MER

  5. 4. Achieving building energy performance : requirements and evaluation methods for residential buildings in Sweden, Norway, and Finland

    Författare :Ingrid Allard; Thomas Olofsson; Gireesh Nair; Ronny Östin; Osama Hassan; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building codes; energy performance; evaluation methods; air tightness;

    Sammanfattning : Building energy performance has always been important in the cold climate of Sweden, Norway and Finland. To meet the goal that all new buildings should be nearly zero-energy buildings by 2020, set in the EU directive 2010/31/EU [1] on the energy performance of buildings (EPBD recast), the building sector in Europe now faces a transition towards buildings with improved energy performance.

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

    Författare :Ingrid Allard Stolterman; Thomas Olofsson; Gireesh Nair; Folke Björk; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
