INFLUÊNCIA DE FACHADAS VERDES NOS MICROCLIMAS DE UM ESPAÇO DE TRANSIÇÃO

Abstract

Scientific studies confirm the thermal mitigation effect of green façades, both indoors and outdoors, but there is still a shortage of studies in transitional spaces. The green facades use species of climbers that can grow and develop directly in the building (direct) or use supports for their development (indirect). The objective of this experimental study was to identify the thermal mitigation effect of indirect green façades in a transitional space, oriented to the West, of a university environment in the city of Bauru-SP. Three green façade modules were constructed with three different climber species, and the microclimatic variables were monitored: Air Temperature (TAR) and Mean Radiant Temperature (TRM) and Absolute Air Humidity (UA) at three points with the influence of the shading of the green facades and an unprotected control point. The results showed maximum reductions of 4,0 °C and 18.8 °C for TAR and TRM, respectively, in the points protected by the green façades in relation to the control point, in addition to an increase of 1,1 g/Kg of absolute humidity in relation to the control point. These results confirm the thermal mitigating potential of the green façades due to the effects of shading and evapotranspiration in transitional spaces and show that they are important bioclimatic strategies. In addition, the research contributed to a better knowledge about the thermal mitigating potential of green façades in transitional spaces and the influence of morphological aspects of the selected plant species in the attenuation of solar radiation.
