Given the environmental and energy saving effect of the use of small wind turbines in urban environments, scientists, architects, manufacturers, investors and government institutions have joined forces for more extensive studies. The paper deals with research work of the optimized design of Darrieus turbine with 1 kW rated power in a particular climate. For purposes of the study a universal algorithm implemented with code in C++ has been developed. Thus it is possible to determine the turbine power developed and its efficiency in climate change factors air temperature, speed and intensity of the wind. The monitoring data cover a period of six months (a total of 18 533 measurements) for specific climatic region.
