Resumen
La necesidad de incrementar la eficiencia energética de los edificios y de reducir el impacto ambiental asociado al uso de materiales convencionales impulsa la búsqueda de soluciones constructivas más sostenibles. En este contexto, este estudio analiza el comportamiento térmico y energético de un biomaterial basado en micelio (MBC) comparado con el poliestireno expandido (EPS) en sistemas constructivos livianos (tipo SIP). Se evaluaron sus propiedades térmicas y su incidencia en el desempeño energético de un prototipo ubicado en dos zonas bioambientales (IVa y V) de la provincia de Mendoza, Argentina. El análisis incluyó el cálculo del valor U según normativas y simulaciones energéticas realizadas en EnergyPlus. Los principales resultados muestran que el MBC debe incrementar su espesor a 75 mm, para alcanzar un rendimiento comparable al de un EPS de 50 mm. Entre ambos aislantes se observa una diferencia de la demanda anual de calefacción del 1%. Los resultados indican que el MBC constituye una alternativa viable para su aplicación como aislante térmico y refuerzan la necesidad de resolver desafíos vinculados al desarrollo de estas nuevas tecnologías considerando aspectos físicos (como la reducción de su peso), durabilidad y producción su fabricación a escala industrial que posibiliten la viabilidad de su implementación.
Improving the energy efficiency of buildings and reducing the environmental burden associated with conventional insulation materials has intensified the search for more sustainable construction alternatives. This study investigates the thermal and energy performance of a mycelium-based composite (MBC) in comparison with expanded polystyrene (EPS) within lightweight structural insulated panel (SIP) systems. Thermal properties and their influence on the energy behavior of a simplified prototype located in two bioenvironmental zones (IVa and V) of Mendoza, Argentina, were assessed. The analysis involved the determination of U-values following relevant standards and building energy simulations conducted in EnergyPlus. The main results show that the MBC must increase its thickness to 75 mm in order to achieve a performance comparable to that of a 50 mm EPS. A 1% difference in annual heating demand is observed between the two insulation materials. Overall, the findings position MBC as a promising thermal insulation alternative and underscore the need to address remaining challenges related to its physical properties, durability, and scalable manufacturing to support its practical adoption in the construction sector.
