Comportamiento comparado de aspectos lumínicos de viviendas modificadas por normas urbanísticas en las laderas este y oeste de Medellín

Abstract

Since 1998, Colombia has been applying land-use plans to its cities, dividing the urban area into intervention polygons, each with a specific destination. A study is presented that evaluated the effect of urban policies regulated in the land use plan on the natural light resource in the houses of the city of Medellin in two polygons located on the valley slopes. Using Climate Studio simulation software, the Useful Daylight Illuminance (UDI) and Spatial Daylighting Autonomy (sDA) parameters were evaluated between 300 and 3000 lx in four orientations of the typical house on each side of the valley and with a variation between one and three floors in height. In all cases, the extra energy consumption used to illuminate darker spaces represents an average additional consumption of 3.83%, the results were statistically validated by Pearson correlation coefficients and linear regression R².
