In the thesis I discuss the influence of single-sided natural ventilation on cooling of the non-residential building. Between all the building systems the consumption of final energy for cooling is the biggest in modern non-residential buildings. That is why cooling with natural ventilation is one of the most efficient measures to increase energy efficiency of the buildings. The effect of natural cooling with airing dependends on climate characteristics, architectural design of the building, thermal properties of structures of the building and internal heat gains. We focused on a typical office and, based on previous researches, chose models with which it would be possible to take into account the shape of the room, transfer of heat into room components depending on air exchange rate and accumulation of cold in room walls. With the help of software tool EnergyPlus we compared theoretical results with results of numerical modelling. Furthermore, we analysed the climate potential of natural refrigeration in four cities across Europe with different climate conditions. The analysis showed that cooling with natural ventilation can reduce the energy use for cooling typical office by about half in Madrid, 2/3 in Lisbon and 3/4 in Ljubljana and Moscow.
