Abstract (in English)
Dominican vernacular architecture, based on the Spanish-influenced indigenous bohio, is built with natural materials. This housing model has remained practically unchanged for five centuries, responding adequately to the tropical Caribbean climate. However, it is necessary to characterize this behavior to verify the indoor comfort conditions of this housing typology. The aim of this research is to evaluate the behavior of a vernacular house located in Villa Sombrero, Peravia Province, Dominican Republic, using a simulation model. For this purpose, a bohio was selected, which has a simple rectangular volume. Simulations were carried out using Design Builder software, considering the passive strategies incorporated in the bohio. The results indicate that indoor ambient temperature remains within the comfort range throughout the annual cycle. It was confirmed that the highest solar gain through exterior windows occurs in the warmer months. Lighting consumption varies between approximately 195 kWh and 220 kWh, with a more stable behavior during the middle months of the year. CO2 emissions followed the same behavior as lighting consumption since it was the only energized element in the bohio. This research demonstrated that passive strategies implemented in the vernacular dwelling work correctly, except for the minimum illuminance level, which needs to be improved.
La arquitectura vernácula dominicana, basada en el bohío indígena de influencia española, se construye con materiales naturales. Este modelo de vivienda ha permanecido prácticamente inalterado durante cinco siglos, respondiendo adecuadamente al clima tropical caribeño. Sin embargo, es necesario caracterizar este comportamiento para verificar las condiciones de confort interior de esta tipología de vivienda. El objetivo de esta investigación es evaluar el comportamiento de una vivienda vernácula ubicada en Villa Sombrero, provincia Peravia, República Dominicana, utilizando un modelo de simulación. Para ello, se seleccionó un bohío de volumen rectangular simple. Las simulaciones se realizaron utilizando el software Design Builder, considerando las estrategias pasivas incorporadas en el bohío. Los resultados indican que la temperatura ambiente interior se mantiene dentro del rango de confort durante todo el ciclo anual. Se confirmó que la mayor ganancia solar a través de las ventanas exteriores se produce en los meses más cálidos. El consumo de iluminación varía aproximadamente entre 195 kWh y 220 kWh, con un comportamiento más estable durante los meses centrales del año. Las emisiones de CO2 siguieron el mismo comportamiento que el consumo de iluminación al ser el único elemento energizado en el bohío. Esta investigación demostró que las estrategias pasivas implementadas en la vivienda vernácula funcionan correctamente, a excepción del nivel mínimo de iluminancia, que debe ser mejorado.
