The concept of smart cities is based on interconnected modern technologies that are supposed to improve as many aspects of urban life as possible. Modern urban building technologies include large area systems for the sustainable supply of cities with energy, as well as building blocks for mitigating the microclimate in cities, which affects energy use and living comfort.  Researchers from the Laboratory for Environmental Technologies in Buildings have published research in the field that addresses these goals. The article “Comparative analysis of free cooling of photovoltaics - phase change versus evaporative cooling”, published in the Journal of Energy storage (IF 6.583;, presents research on constraints the cooling potential of photovoltaic modules with phase-changing substances in terms of lowering the temperature of building blocks and thus mitigating the urban climate with increased self-sufficiency of cities with energy.  The article "Efficiency and sustainability assessment of evaporative cooling of photovoltaics", published in the journal Energy (IF 7.147;, presents the results of evaporative cooling of photovoltaic modules.  This method has proven to be a most efficient method among techniques of natural cooling, as the temperatures of photovoltaic components at extreme meteorological variables are reduced by more than 20 K. The sustainability of this techniques of natural cooling has been investigated through  optimization of the water reservoirs and ratio between area of photovoltaic modules and precipitation collecting surfaces in different climate conditions.
