Resumen

Con el fin de mitigar el impacto que causa la pérdida del hogar debido a los constantes eventos naturales, se propone el diseño de un sistema constructivo adecuado que permita el alojamiento temporal de los afectados; para esto, se desarrollaron una serie de simulaciones ambientales con medios digitales, que permitieron conocer el desempeño térmico de materiales seleccionados previamente según lineamientos del Life Cycle Assessment (LCA), en relación con los componentes de edificio como cimentación, estructura, envolvente y cubierta, en climas tropicales, aplicado a Bogotá y Girardot. Asimismo, se explora la relación entre los materiales con cuatro configuraciones de diseño y siete tipos de ventilación, a fin de obtener una respuesta multidimensional y sostenible. Como resultado se encontró que materiales como guadua, fibras vegetales y fibras sintéticas, sumado a estrategias de aislamiento y configuraciones de ventilación, pueden aportar al confort térmico en el diseño de alojamientos temporales en el contexto colombiano.

Environmental Simulations for Material Selection in Temporary Housing Design in Tropical Weather Conditions

Abstract

In order to mitigate the impact caused by the loss of home due to the constant natural events that take place, this proposal gives a proper building system design that allows temporary housing for the affected. In this regard, there was a number of environmental simulations with digital media technology, which gave insights on the thermal performance of the material previously selected according to Life Cycle Assesment (LCA) guidelines, regarding building components such as the foundations, structure, envelope and roof, in tropical weather. The simulations were applied in the cities of Bogota and Girardot.

Likewise, there is an exploration of the relation between the materials with four different design configurations and seven types of ventilation, in order to obtain a multidimensional and sustainable answer. Findings show that materials such as guadua, vegetable fibers, and sinthetic fibers, joint with isolation strategies and ventilation configurations, could contribute to thermal comfort in the temporary housing design within the Colombian context.

Key words: Comfort, tropical weather, transitory habitat, modelling, sustainability, temporary housing.
