Los materiales con que habitualmente se construye la envolvente de la vivienda social en clima cálido subhúmedo, al ser evaluados por su conductividad térmica, son ineficientes, porque afectan la habitabilidad interior. Para revertir el estado de ineficiencia térmica de la vivienda se introdujo en la industria de la construcción el uso de materiales termoaislantes que se evalúan por su capacidad de resistir el flujo de calor (resistencia térmica); sin embargo, esta adecuación en la envolvente involucra aumentar la energía incorporada del sistema. El objetivo de esta investigación fue determinar la posibilidad del uso de materiales regionales para su potencial uso como aislante. Las configuraciones de materiales para cubierta fueron seleccionadas por su coeficiente de conductividad térmica y evaluadas por la capacidad de aislamiento según la nmx-c-460-onncce que involucra el cálculo de la resistencia térmica (R). Se identificó de adecuado el desempeño del carrizo (Arundo Donax) y caña maíz (Zea Mays) para elaborar una cubierta para una región específica, que cumple con ahorro de energía al ser evaluada por la nmxc-460-onncce. Se discute el análisis térmico de los materiales solo por su conductividad, ya que existen otras propiedades, como densidad y calor específico, que se relacionan de manera dinámica, independientemente de que no se consideren en la evaluación de la resistencia térmica. Se concluye que el análisis de las propiedades térmicas, previo al diseño, permite seleccionar materiales para configurar envolventes con respuesta térmica eficiente en la región Centro Universitario de Arte, Arquitectura y Diseño 2020-07-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed article Artículo evaluado por pares application/pdf https://www.revistavivienda.cuaad.udg.mx/index.php/rv/article/view/142 10.32870/rvcs.v0i8.142 Vivienda y Comunidades Sustentables; No 8 (2020): Vivienda y Comunidades Sustentables; 59-80 Vivienda y Comunidades Sustentables; Núm. 8 (2020): Vivienda y Comunidades Sustentables; 59-80 2594-0198 10.32870/rvcs.v0i8 spa https://www.revistavivienda.cuaad.udg.mx/index.php/rv/article/view/142/170 |

The materials with which the social housing envelope is usually constructed in sub humid warm climate are thermally inefficient because they lead heat to interior space which affects thermal habitability. To reverse the state of thermal inefficiency of the house was introduced in the construction industry the use of thermo-insulating materials that are evaluated for their ability to resist the heat flow (Thermal Resistance), however, this adequacy in the envelope involves an additional economic cost in a context of shortage. Therefore, the objective of this research was to determine the possibility of the use of materials from the region for potential use as an insulator. Selecting the configurations of roofing materials by their coefficient of thermal conductivity and evaluating by the insulation capacity according to the nmx-c-460-onncce involving the calculation of the Thermal Resistance (R); The performance of carrizo (Arundo Donax), corn cane (Mayz Zea) and the soil was evaluating to develop a roof for the region, according to the nmx-c-460-onncce meets for energy savings. Thermal analysis of materials is discussed only for their conductivity as there are other properties such as density and specific heat, that are dynamically related, independently that are not considered in the evaluation of thermal resistance. It is concluded that the analysis of pre-design thermal properties allows to select materials with adequate thermal response in the region to build efficient architectural envelopes. |
