  4. 3. Refined distribution of frit. Method and design tool for improved thermal comfort in glazed spaces.

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Magdalena Stefanowicz; Amanda O'Donnell; [2016]
    Nyckelord :frit; solar shading; parametric design; overheating; g-value; glazed spaces; thermal comfort; Technology and Engineering;

    Sammanfattning : Thermal comfort in highly glazed buildings has long proven to be a troublesome matter due to unwanted passive solar heat gains. Excessive solar gains are commonly counteracted with energy-intensive cooling systems and/or comprehensive shading devices. Shading devices are used to adjust solar heat transmission through glazing.

    Sammanfattning : Corn is an important food and feed crop in the world, in Sweden it's up till now grown on limited acreages mainly for silage. But I think it can get more important if you can grow it also for grain, because it's a good animal feed for example, for life stock-, pigsand poultry. LÄS MER
