  3. 7. Optical Characterization and Energy Simulation of Glazing for High-Performance Windows

    Författare :Andreas Jonsson; Arne Roos; Werner Platzer; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy simulations; antireflection coatings; dip-coating; optical measurements; spectrophotometer; integrating spheres; low-e windows; solar control windows; smart windows; control strategies; U value; g-value; Engineering physics; Teknisk fysik; Engineering Science; teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : This thesis focuses on one important component of the energy system - the window. Windows are installed in buildings mainly to create visual contact with the surroundings and to let in daylight, and should also be heat and sound insulating. LÄS MER

  4. 8. Optical Characterisation of Miniature Structures and Translucent Sheets for Daylighting Applications

    Författare :Jacob Jonsson; Arne Roos; Helen Rose-Wilson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Photospectrometry; Light scattering; Optical characterisation; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : For a long time spectrophotometry has been a powerful method of determining optical material properties. Since the technique measures the parameters of interest, reflectance and transmittance, it is in general easy to use and interpret. LÄS MER

  5. 9. Daylighting Systems : Development of Techniques for Optical Characterization and Performance Evaluation

    Författare :Annica M. Nilsson; Arne Roos; Claes-Göran Granqvist; Marie-Claude Dubois; Michael Köhl; Uppsala universitet; []
    Nyckelord :Optical spectroscopy; integrating sphere; ray tracing; light scattering; window physics; Venetian blinds; core daylighting; optical characterization; Teknisk fysik; Engineering Science;

    Sammanfattning : Successful integration of daylighting systems requires the ability to predict their performance for given climates. In this dissertation, a bottom-up approach is applied to evaluate the optical performance of a selection of daylighting systems. LÄS MER

  7. 10. Windows of Opportunities : The Glazed Area and its Impact on the Energy Balance of Buildings

    Författare :Mari-Louise Persson; Arne Roos; Maria Wall; Ida Bryn; Uppsala universitet; []
    Nyckelord :Engineering physics; building simulations; DEROB-LTH; glazing; window size; energy efficiency; glazed area; Teknisk fysik;

    Sammanfattning : The impact of window area on the energy balance of a building was investigated by simulations in DEROB-LTH. The glazed area was varied in three types of buildings with different types of glazing and for several climates.One low energy house was compared to a less insulated house but identical in size and layout.
