Abstract
Vegetation is an excellent strategy to tackle global warming and climate change. In this context, the green wall is a kind of green infrastructure that is used as a bioclimatic strategy. Also, it can be used as an approach to insert green areas in an urban context, contributing to urban areas to become more sustainable. This chapter aims to evaluate the thermal performance of green walls using three different native climbing vegetation from the Cerrado biome. Thus, the authors used a computational tool named ENVI-met (v.3) as a method to analyze and evaluate which plants would bring the best performance in terms of improving thermal comfort. The database the authors obtained from the simulations will serve as a comparison of the thermal performance between walls without vegetation cover, as well as clarify the morphological and physiological characteristics that influence its thermal performance. The results demonstrate that Arrabidaea pulchra species enabled green walls with lower temperatures and higher air humidity rate in most situations.
