    Khosravi, Shiva; Šikula, Ondřej; Pont, Ulrich; Mahdavi, Ardeshir (IOP Publishing, 2019-06-27)
    Windows have been a subject of interest for research in building industry due to their multifaceted and significant implications for indoor environmental quality and energy use. In this context, the present contribution ...
  • Experimental and numerical study of turbulent flow around a Fanwings profile 

    BENFERHAT, Slimane; Tayeb, Yahiaoui; IMINE, Bachir; Ladjedel, Omar; Šikula, Ondřej (Taylor & Francis Group, 2019-07-20)
    The main objective of this paper is an experimental and numerical study of airflow on a propulsive wing also called ventilated wing or FANWING, which is a drone operating at low speed. To optimize the aerodynamic shape of ...
  • The possibilities of application of radiant wall cooling in existing buildings as a part of their retrofit 

    Krajčík, Michal; Šikula, Ondřej (EDP Sciences, 2019-08-13)
    In the following years and decades the increase in cooling capacity will put tremendous pressure on the energy infrastructure and severely increase the environmental impacts. In a moderate climate and well thermally insulated ...
  • Radiant wall cooling with pipes arranged in insulation panels attached to facades of existing buildings 

    Šimko, Martin; Krajčík, Michal; Šikula, Ondřej (EDP Sciences, 2019-08-13)
    Radiant systems are being increasingly used for space heating and cooling of buildings. The contemporary research of radiant systems addresses mainly floor and ceiling structures. Research regarding the possibilities of ...
  • Energy, economic and environmental analysis of opened natural healing water source 

    Miček, Denis; Hirš, Jiří (EDP Sciences, 2019-08-13)
    European´s low carbon economy is the main target in the way of the reducing greenhouse gases at the Earth´s atmosphere. The most promising way is in maximal usage of renewable sources of energy such as geothermal energy, ...
  • Impact of IPPC Scenarios on indoor environment quality of historic buildings 

    Weyr, Jan; Hirš, Jiří; Kalný, Richard (EDP Sciences, 2019-08-13)
    Ensuring proper indoor environment quality in buildings with historic value or buildings located in historic centres of cities is not an easy task. These buildings are frequently listed in historic preservation lists; thus, ...
  • An Evaluation of the Mathematical Models of Energy Piles 

    Oravec, Jakub; Šikula, Ondřej; Nováková, Iva (Sciendo, 2020-04-03)
    A current trend is to reduce the energy performance of buildings by using alternative sources for heating and cooling. One of the most promising, and so far unprecedented sources of heating and cooling, is the use of energy ...
  • Numeric Simulation of Heat Transfer Phenomena in Existing and Retrofitted Casement Windows
