Variation of the Temperature and Environmental Humidity in Solid Concrete Slabs for Mezzanine Buildings Using the Species <i>Aptenia cordifolia</i> and <i>Sphagneticola trilobata</i>

Abstract

The current population is increasing rapidly and as a consequence a greater number of houses is required, which are consolidated through urbanizations; which modify the hydrological processes, alter the energy exchanges between the sun, the surface and the atmosphere, generating changes in the flows and components of the radiation balance that affect the urban heat island. An alternative to control this heat is to promote a green space through green roofs that improve the urban climate. The present research work studies on prototypes of solid concrete slabs the effect of the plant species Aptenia cordifolia and Sphagneticola trilobata on the temperature and environmental humidity in an extensive green roof. The results indicate that both species have a different behavior, being the species Sphagneticola trilobata the one that presents a better behavior before the higher and lower environmental temperature and higher relative humidity; while the Aptenia cordifolia presents it behaves better before the lower relative humidity.
