In oasis cities urban forest shades the lower level facades of buildings. It is thus crucial to analyze the distributional patterns of sun radiation produced by trees on facades. On the assumption that lighting behavior of trees as sun control elements more closely resembles a louvers system rather than other frequently used solar control systems (ej. perforated obstruction), the present study seeks to verify which of these formal simplifications adjusts better to the real case. The methodology used in this study relies on simulation models generated with hemispherical images. Louvers model showed a high degree of adjustment (RMSE 9%).
