Resumen
En la ciudad de Mendoza, Argentina, las viviendas presentan mayoritariamente una baja calidad constructiva en relación con la falta de aislamiento de sus envolventes. Se estima que el 95% de las viviendas existentes no están aisladas en su envolvente vertical y presentan aislamiento insuficiente en techos. En un clima templado continental, con grandes amplitudes térmicas diarias y estacionales, las viviendas presentan inercia térmica como única estrategia bioclimática. En estas circunstancias, las posibilidades de gestión que ofrezca la envolvente -a través de elementos practicables y/o móviles-, son claves para la aproximación al logro del confort interior. El presente trabajo analiza la influencia del uso y gestión de las aberturas en la envolvente a cargo del usuario en una vivienda tradicional, mediante monitoreo higrotérmico, durante 59 días en verano. Para ello, se midieron dos períodos con distintas condiciones climáticas (extremas y moderadas) en los que se aplicó la estrategia de ventilación natural nocturna, gracias a la cual se obtuvo 82% de horas en confort. Asimismo, se midió un período sin gestión de las aberturas en la envolvente, es decir, manteniéndolas cerradas; de lo que resultó solo un 6% de horas en confort. Se concluye, en suma, que la intervención comprometida y consciente del usuario mediante el aprovechamiento de la ventilación nocturna, en combinación con la inercia térmica de la envolvente, influye de manera positiva sobre el comportamiento térmico de la vivienda.
In the city of Mendoza, Argentina, houses have mostly low constructive quality related to the lack of insulation in their envelopes. In a temperate continental climate, with important daily and seasonal thermal amplitudes, the houses have thermal inertia as the only bioclimatic strategy. In these circumstances the possibilities of management offered by the envelope–through movable and operable elements-, are key for achieving indoor thermal comfort, reducing the overheating in summer. This work analyses the influence of the use and management of the envelope by the user in a traditional house, by hydrothermal monitoring during 59 days in summer. Two periods with extreme and moderate climatic conditions, were measured, in which the nocturnal ventilation strategy for cooling, combined with the closure of windows during daytime, allowed obtaining 82% of comfort hours. A period without management of the envelope and when the house remained completely closed during daytime and nighttime, was also measured, obtaining only 6% of hours in comfort. It is concluded that the committed and conscious intervention of the user through the use of night ventilation as a cooling strategy, in combination with the thermal inertia of the envelope, play an important role in achieving indoor thermal conditions reducing overheating during summer.
