Résumé

In the paper are presented some methods of buildings cooling load reduction, lowering - as much as possible - capacities of the refrigeration systems to be used in a building air conditioning systems. One way is to copy the human body reaction to high ambient temperatures by perspiration, producing the evaporation cooling effect above building facades using water flowing along façade lowering cooling load and needs of mechanical cooling. To avoid use of large quantities of water a new coating technology with TiO2, is developed. The facades, either of glass or a concrete, or any another appropriate material, are coated by TiO2 which is hydrophilic so the distribution of the water is becoming uniform with very thin water layer. The results of investigation of such system are presented and discussed in the paper. The another possibility is application of phase change material in building elements producing cooling effect in combination with natural or mechanical ventilation, or with the help of refrigeration mechanical systems operating during the periods of lower electricity tariff. The effect of classical double facades are not analysed in this paper, as they are primary used for protection of a building in cold climates and cold periods of a year.
