| Abstract | espanolEl presente estudio tiene por objetivo evaluar la influencia de los materiales en las envolventes verticales sobre la disponibilidad de luz natural, en escenarios urbanos representativos de la ciudad de Concepcion, con el fin de conocer el potencial de los materiales para aportar luz natural. La metodologia se basa en la seleccion de casos de estudio del centro historico de Concepcion para armar modelos simplificados segun su relacion alto/ancho (H/W). Dentro de cada caso se escogen materiales de fachadas que muestren mayor presencia en el canon urbano, para calcular su reflectancia y ser aplicados a los escenarios simulados. Los resultados demuestran que la disponibilidad de luz natural exterior se ve directamente condicionada por la relacion geometrica del canon urbano, la cual disminuye conforme aumenta la relacion H/W. Se comprueba que el aporte luminico debido al coeficiente de reflectancia del material que compone la fachada es mayor conforme aumenta la relacion H/W, es decir, mientras mayor sea la densidad del canon urbano, mayor sera la importancia de las propiedades reflectantes de los materiales de fachadas frente a la disponibilidad de luz natural. EnglishThe objective of this study is to evaluate the influence a vertical envelope s material has on the availability of natural light in urban settings representative of the city of Concepcion, in order to know the potential of these materials to provide natural light. The methodology was based on the selection of case studies from the historic Concepcion downtown to build simplified models according to their height/width ratio (H/W). In each case, facade materials with greater presence in the urban canyon were chosen to calculate their reflectance and use in the simulated settings. The results show that the availability of exterior natural light is directly conditioned by the geometric relationship of the urban canyon, which decreases as the H/W ratio increases. It was confirmed that the lighting contribution from the reflection coefficient of the facade s material is greater as the H/W ratio increases, that is to say, the greater the density of the urban canyon, the greater the importance of the reflective properties of the facade materials with regards to the availability of natural light. |
