Analysis of wind flow upon high-rise buildings is very common topic. Nowadays, there are no general or analytical ways how to analyze wind effects on irregular shaped high-rise buildings complexes. Scaled experiments tested in wind tunnels are best for precise solutions, however they are time consuming and expensive too. Therefore we use computational modeling software based on finite volume method to analyze these effects and then, thanks to these analysis we can design structures and optimize them. Paper deals with simplified 3D analysis of wind effects on high-rise buildings complex "Panorama City" located in Bratislava-Slovakia. Through this analysis we obtain results for wind speed near objects and external pressure coefficient as well. Both of them will be helpful to gain insight for future constructions or verification of already constructed ones.

The relevance of the study is associated with the need to determine scientifically based principles for the design of wind-powered high-rise buildings. The article analyzes the main climatic parameters affecting the design of wind-powered high-rise buildings. While current research focuses mainly on the technical performance and savings of wind power plants (WPPs), modeling wind energy potential based on the analysis of climatic parameters allows you to optimize design solutions taking into account the influence of the environment. For various stages of the design of the integration of wind turbines into a high-rise building, it is important to take into account the dimensions of climate systems (macro, meso and micro levels), based on the laws operating within certain territorial boundaries. The article discusses the macroclimatic indicators that determine the total energy resource of wind in the region. The influence of the parameters of the mesoclimate on the wind potential has been determined, in accordance with the characteristics of the natural and anthropogenic environment (relief, the presence of forests, proximity to water bodies, urban development). The parameters that clarify the energy potential of the wind at the microclimatic level, taking into account the location of the wind turbine in the building, have been investigated. As a result of the analysis, a diagram of the structure of preliminary modeling of the energy wind potential at various climatic levels in the design of wind turbines in high-rise buildings has been determined.
