La investigación considera la hipótesis de que el uso del dispositivo "bandeja de luz" puede contribuir a optimizar la distribución y el control de la luz natural interna, mejorando el confort visual y aumentando la eficiencia energética del edificio. El objetivo de la investigación fue evaluar la influencia de ese dispositivo en combinación con diferentes tipos de vidrio en condiciones de obstrucción externa, acercándose a la realidad del modelo de urbanización con rascacielos. Se escogieron seis ciudades brasileñas en diferentes latitudes, donde se simuló un edificio de oficinas y se consideraron ventanas con diferentes porcentajes de obstrucción de la bóveda celeste. Se analizó la iluminanciaútil (Useful Daylight Illuminances - UDI) por medio del software Daysim, comprobando que el incremento de edificios verticales en los centros urbanos —modelo usual en las ciudades brasileñas— puede interferir en la calidad lumínica del ambiente interno.
The research considers the hypothesis that the use of the device known as "light shelf" could contribute to optimize internal natural light distribution and control, improving visual comfort and increasing the building's energy efficiency. The purpose of the inquiry was to evaluate the device's influence combined with different types of glasses in condition of external obstruction, resembling the reality of the urbanization model with skyscrapers. Three Brazilian cities in different latitudes were chosen, where a simulation of an office building with windows having different obstruction percentages of the celestial sphere took place. With the help of Daysim software, we analyzed the Useful Daylight Illuminances —UDI, verifying that the increase of vertical buildings in urban centers —the usual model in Brazilian cities- could interfere in the quality of light of the internal atmosphere.
