Determinar el impacto de sombras por construcciones en altura de las UPZ Las Nieves y Sagrado Corazón en Bogotá mediante condiciones de soleamiento

Abstract

The present work was developed in order to meet the objective of determining the effects on access to sunlight, on different types of urban spaces of the UPZ the snow and sacred heart, through the use of spatial analysis tools. At present, due to population growth and urban infrastructure, the construction of high-rise buildings is being promoted, which is generating an impact on buildings with fewer floors, this is because in Colombia there is no regulation that guarantees the solar access to buildings. In addition, no plan of shading of the country contemplates a study of shadows to define the maximum vertical buildability for a property. In the hypothesis of this work, it is considered to be taken into account for territorial planning issues. The information necessary for the development of this project was downloaded from the spatial data infrastructure for the capital district (IDECA), which demonstrates the importance of public or private institutions, implement open data policies that facilitate the development of research projects. Subsequently, the study area was defined, feature 2.5D and a digital elevation model were created; which were fundamental to use the hillshade and sun shadow volume tools of Arcgis, these tools as a result generates a raster with the shadow projection of the buildings and the volume of shadows respectively. The calculations of the affectations were made with the shadow projection raster, demonstrating the affectation on the buildings considered as sites of interest in terms of area covered by shadow and accumulation of shadow hours, with this generated information the existence of the impact on the solar access of these buildings, which demonstrates the importance of continuing to generate and deepen the issue of shadows in territorial planning and in different applications that have this type of study.
