  2. 1. Lifetime Performance Assessment of Thermal Systems : Studies on Building, Solar and Disctrict Heating Applications

    Author : Bojan Stojanovic; Christer Sjöström; Per Jostein Hovde; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lifetime performance; degradation; assessment; modelling; field exposure; thermal components and system; Building engineering; Byggnadsteknik; Materials science; Teknisk materialvetenskap;

    Abstract : The main questions today concerning thermal systems are their economical and environmental impacts. These entities are generally, at present, assessed on the basis of operation performances of newly installed/designed systems, during an assumed lifetime period. READ MORE

  4. 2. 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

  5. 3. Life performance assessment methodologies for combined solar energy technologies : a case study on system parts in nordic climates

    Author : Bojan Stojanovic; Christer Sjöström; Björn Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life performance; assessment; combined solar energy technologies; degradation; component and system performance; Building engineering; Byggnadsteknik; Materials science;

    Abstract : The main questions concerning energy technologies today are their economical and environmental impacts. These entities are (at the present) assessed on the basis that operations proceed as newly installed/designed systems, during an assumed working life period. READ MORE

  6. 4. Resistance of Circular and Polygonal Steel Towers for Wind Turbines : Down scale component experiments and Finite element analysis

    Author : Anh Tuan Tran; Florea Dinu; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : With increasing demand of sustainable energy production, the harvesting of wind power by using wind turbines have become increasingly important over the last few decades. Most of the wind turbine towers are made from steel. Towers are an important part of the investment in wind parks and contribute about 20% of costs for the onshore towers. READ MORE

  7. 5. Advances in Thermal Insulation : Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

    Author : Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

    Abstract : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. READ MORE
