Trees are complex elements when observed in relation to the transmission, reflection, and dispersion of light. Variables such as height, geometry, and shape of the crown, leaves and branches, as well as color and transparency impacts on the light path. Considering the highlighted aspects, this article presents the proposition, experimentation, and analysis of a method for predicting the impact of vegetation on daylighting in indoor environments. The method consists of using a small-scale tree species (bonsai), simulating a full-scale tree, together with four indoor environments, also on a reduced scale. Real sky illuminance measurements were conducted and analyzed. The results show that the obstruction caused by vegetation significantly reduces (68%) the internal illuminance, on the other hand, the vegetation contributes to the uniformity of lighting levels.
