This article presents the results of a study of aerosols solid particles movement inside ventilated air space of the ventilation facade. Particles of pollutants in the form of solid aerosol particles penetrate inside the air space of the ventilated façade. In the scientific literature, studies of settling processes (downward movement) of pollutant particles are given. However, the patterns of their movement inside the ventilated facades structure have not been studied thoroughly. The calculation method proposed by the author makes it possible to establish the speed of aerosol solid particles movement inside the ventilated air space of the ventilation facade and establish whether the particles will move upward together with the air flow or will settle on the structural elements of the ventilation facade facing the ventilated air space, taking into account the air flow rate and its temperature, and the size and density of aerosol contaminants.
