Resumen

Considerando la tapia como una alternativa sustentable en promoción de confort térmico, sus propiedades higrotérmicas fueran parametrizó para determinar la importancia de diferentes métodos de simulación computacional y los intervalos de confianza en la evaluación del desempeño termoenergético. Un edificio con tapia se simuló en el software EnergyPlus y JePlus utilizando los modelos de función de transferencia de conducción (CTF) y profundidad de penetración de humedad efectiva (EMPD). Estas simulaciones se analizaron mediante ANOVA, sensibilidad e incertidumbre con las siguientes variables: espesor de pared, propiedades higrotérmicas empíricas y rutina de uso del edificio. Los resultados demostraron que el método CTF se puede utilizar sin pérdida significativa de precisión para los indicadores de las simulaciones termoenergéticas de tapia en un clima tropical con veranos húmedos e inviernos secos. El espesor y la conductividad de la tapia, junto con la rutina de uso y la ocupación, mostraron una influencia significativa en el consumo de energía. Los intervalos de confianza para las propiedades higrotérmicas de la tapia fueron: 1780 a 2025 kg/m³ para densidad; 0,85 a 0,93 W/m.K para conductividad térmica; 750 a 800 J/kg.K para calor específico; 13 a 14 para factor de resistencia a la difusión del vapor de agua.
