Analysis of roof cooling fans function in several working regimes is presented. The main goal of the research was to define the influence of fan working regime on inside air temperature and velocity. Those two are the main microclimate parameters. Their values should be maintained in optimal ranges. During the different fan speeds, the measurements were conducted in characteristic building sections. Air temperature and humidity measurements were conducted in were 48 measuring points selected, in 4 height levels, which totally covered the room. Comparative analysis of air flow velocities showed the effects of fans function in particular zones, as well as potential problems that ventilation system may provide. It was concluded that this fans disposal doesn't achieve satisfactory results in every experimental setup. The change of fans setup was recommended, as well as possibility of a third fan installation, along with some building corrections.
