  1. 1. Windows Optical Performance and Energy Efficiency

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Joakim Karlsson; A. Maccari; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : This thesis treats angle-resolved optical properties and the energy efficiency of windows. A theoretical evaluation of optical and thermal properties of windows is briefly surveyed and the energy performance of a large selection of windows, under different conditions, is examined. In particular, angle dependent optical properties are analysed. LÄS MER

  2. 2. Windows of Opportunities The Glazed Area and its Impact on the Energy Balance of Buildings

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mari-Louise Persson; Arne Roos; Maria Wall; Ida Bryn; [2006]
    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.

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Andreas Jonsson; Arne Roos; Werner Platzer; [2009]
    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; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP 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. 4. External Water Condensation and Angular Solar Absorptance Theoretical Analysis and Practical Experience of Modern Windows

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anna Werner; Uppsala universitet.; [2007]
    Nyckelord :Engineering physics; Windows; External condensation; Radiative cooling; Optical properties; Coated glass; External condensation; Radiant cooling; Teknisk fysik;

    Sammanfattning : Part I of this thesis is a theoretical background to parts II and III.Part II treats the phenomenon of decreased visibility through a glazing due to external water condensation, dew, on the external surface. Some simulations are presented where it is shown that under certain circumstances condensation can be expected. LÄS MER

  5. 5. NOUR - Daylighting and thermal effects of windows in desert houses

    Detta är en avhandling från Architecture & Development Studies, Lund University

    Författare :Djamel Ouahrani; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal simulation; Solar aspects; Housing architecture; Ghardaia; Desert; Daylighting simulation; Daylighting; Data collecting; Data analysis; Culture; Climate adaption; Algeria; Architecture; Traditional architecture; Windows; interior design; Arkitektur; inredningsarkitektur;

    Sammanfattning : This study is on a combined effect of window, the daylighting and the thermal effects, in desert houses. It is comprised of two complementary studies. In the introduction a historical review on the development of use daylight has been carried out in order to place the case study in a historical perspective. LÄS MER
