Evaluación térmica de la sustitución del material de la capa de drenaje en techos verdes por llantas usadas - análisis experimental en el II periodo húmedo climático del 2016, Bogotá
2018
In the Bogota city, the used tires end in streets, wetlands and even in residential spaces, representing an aesthetic, sanitary and environmental problem. To analyze quantitatively the advantage of thermal regulation of these modified with tires in comparison to the green roofs extensive conventional is the object of study. By means of pilot test six buildings were constructed to scale, for two groups handled of agreement to the type of roof: Eternit® gray fiber cement and Spanish clay tile. The information of temperature internal temperature (Ti) and the temperature environment (Ta) were taken in the field two times a day in climatic conditions of a moist season in Bogota. The results show that, the conventional green ceilings ultimately attenuate the internal temperature of the constructions relative to the control system for each group, about 0,5°C; However, differences were observed between the behavior of ceilings with drainage substitutes, increasing 0,2 ° C for “Eternit®”, and decreasing 0,5 ° C for “Espanola”.
