  1. 1. Windows : Optical Performance and Energy Efficiency

    Författare :Joakim Karlsson; A. Maccari; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; 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

  3. 2. Rum utan utsikt : Fönster och ljus i medeltida byggnader

    Författare :Linda Qviström; Anders Andrén; Herman Bengtsson; Martin Hansson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Medieval Archaeology; Post Medieval Archaeology; Windows; Medieval Buildings; Light Openings; Window Glass; View; Interiors; Darkness; Light; Lighting; Light Equipment; Arkeologi; historisk arkeologi; medeltida byggnader; fönster; ljusöppningar; fönsterglas; utsikt; inomhusmiljö; mörker; ljus; belysning; belysningsredskap; Uppland; Gotland; arkeologi; Archaeology;

    Sammanfattning : Windows, light and a view are self-evident parts of contemporary interiors. This was not the case in Scandinavia during the Middle Ages (c. 1050–1520 CE), when closed spaces without wall openings were standard. LÄS MER

  4. 3. 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.

  5. 4. 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

  7. 5. External Water Condensation and Angular Solar Absorptance : Theoretical Analysis and Practical Experience of Modern Windows

    Författare :Anna Werner; Arne Roos; Claes-Göran Granqvist; Svend Svendsen; Uppsala universitet; []
    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
