- PublicaciónAcceso abiertoBioclimática de fachadas perforadas realizadas con materiales y técnicas autóctonas del pacífico colombiano, caso de estudio de vivienda en Quibdó(2020) Perea Palacios, Edwin; García Cardona, Ader AugustoIn areas with a humid tropical climate, ventilation is essential to achieve thermal comfort inside the houses, the temperature and relative humidity must be controlled through the materiality of the facades used, there are areas of the tropics that still preserve ancestral customs to build their homes with good thermal results; This research addressed the study of indigenous techniques and materials used by the inhabitants of the Colombian Pacific for the elaboration of their enclosures or housing enclosures in Afro-descendant and indigenous cultures. The objective was to scientifically evaluate how three (3) vegetable fibers used as perforated facades in traditional houses in the Colombian Pacific behave; The indigenous culture uses fibers from Iraca Carludovica palmata (Ruiz & Pav). As a protection curtain against solar rays, the Afro-descendant culture uses the fiber of plantain or platanillo; A third fiber used by the two cultures is the palm or chonta Iriartea deltoidea (Ruiz & Pav), used in the construction of facades for their homes. This research was based on laboratory studies carried out at the Universidad de Nacional, Medellín, real house study and simulations in DesingBuilder and AutoDesk software, for which we used a soundproof camera, a wind tunnel and Dataloger type sensors to obtain temperature data, relative humidity, lighting, a sound level meter to measure sound pressure and videos for the qualitative analysis of the air flow of each fiber. After the analysis and simulations, the palm presented the best performance, achieving a reduction of 2.4 ° C in temperature and 18.25 dBA as sound insulating fiber; Additionally, it was evidenced that a 1m2 of construction in palm costs 50% less than in concrete block and its carbon footprint is 95% lower.
