RT Journal Article T1 A Methodological Proposal for the Analysis of Lighting the House Building Façades. A1 Castro Noblejas, Hugo A1 Sortino-Barrionuevo, Juan Francisco A1 Gumiel Muñoz, Darío A1 Mérida-Rodríguez, Matías Francisco K1 Iluminación natural K1 Urbanismo - Aspectos ambientales AB Natural lighting is a fundamental element in the habitability of dwellings. However, it isstill difficult to calculate its effect on the façades of the buildings in detail, due to the morphologicalcomplexity of the property itself, as well as the environment that surrounds it. This study providesa methodological proposal that uses pre-existing open data to extrude buildings by using a GISprocedure. Based on three selected real estate properties with different characteristics in the city ofMarbella (Spain), the hours of sunlight received by each building’s façade are calculated, taking intoaccount the digital land model and the digital surface model of the area. The results confirm theusefulness of the method to measure and analyze differences in luminosity between buildings withsimilar urban characteristics and their surroundings, as well as to record the differences in luminositybetween floors and the orientations of the same building at several heights. The methodologicalproposal opens a path for many applications related to energy efficiency, housing conditions, andproperty valuation.
