  1. 1. Energy simulation model for commercial buildings Beridarebanan 4, 11 and 77, with ice thermal storage

    University essay from KTH/Energiteknik; KTH/Energiteknik

    Author : Martin Henning; Endi Tollkuci; [2019]
    Keywords : ;

    Abstract : District cooling companies enforce a large penalty based on peak demands, which current cooling methods do not address properly. Building developers are exploring alternatives methods to reduce the said peak demands. READ MORE

  2. 2. Optimization of a large scale solar installation through virtual storage : Profitability of using the refrigeration system in a grocery store as energy storage

    University essay from

    Author : Erik Larsson; Jesper Sundin; [2019]
    Keywords : PV; solar power; virtual storage;

    Abstract : In order to fulfil the goals set by EU and in the Swedish energy agreement an increased share of renewable electricity production, like wind and solar power, is necessary. Due to current legislations photovoltaic (PV) installations are usually limited to the 255 kWp energy taxation rule, or to fit the consumption profile of the building. READ MORE

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Tabassom Hashemi Farzad; [2019]
    Keywords : Photovoltaic PV system; Microgrid system; Functional unit; Kilowatt peak kWp ; Ehup;

    Abstract : Application of Photovoltaic PV panels for electricity production has rapidly increased in recent years in Sweden after launching a capital subsidy for PV panel installations in 2009. Kungsbacka municipality’s housing company equipped two groups of buildings in Fjärås with PV systems to generate electricity. READ MORE

  4. 4. Study of defects in PV modules : UV fluorescence and Thermographic photography for Photovoltaics (PV) Field Application

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Sophie Nylund; Zahra Barbari; [2019]
    Keywords : UV fluorescence; IR thermography; defects in PV modules; delamination; discoloration; hotspots; snail trails; cracks; fault in bypass diode; non-functioning cell in PV;

    Abstract : For a PV plant it is of fundamental importance that the operation of the PV modules is free from faults or at least that the faults can be detected early, to ensure efficient electricity production. Some defects such as cracks can be seen in visible light while microcracks and damage to the silicon material can only be seen through special lighting. READ MORE

  5. 5. The effects of low-emissivity window films on thermal comfort and energy performance of a historic stone building in cold climate: computer simulations with "IDA ICE"

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Author : Saman Abolghasemi Moghaddam; [2019]
    Keywords : Low-E window films; low-emissivity window films; thermal comfort; IDA ICE; solar heat gain; U-value; building energy saving measures; heating demand; cooling demand;

    Abstract : Low-emissivity (low-E) window films are designed to improve the energy performance of windows and prevent indoor overheating by solar radiation. These films can be applied to different types of glazing units without the need for changing the whole window. READ MORE
