Analysis of the spatial distribution of urban green areas in thermal quality in a semi-arid climate region

Abstract

The implications of the growth of cities, which occur in a way to subdue natural spaces, have become evident in recent decades. Thus, we sought to analyze the relationship between the configurations of green areas with afforestation in reducing air temperature and maintaining specific humidity, in hot and dry weather conditions. For this purpose, five parameterized scenarios were developed that present green areas in 10% of the general area of the land, in different forms of spatialization: central, distributed, linear, mixed and peripheral. All parameterized scenarios were modeled in the ENVI-Met 4.0 software to generate simulations demonstrating the hygrothermal behavior of the scenarios. The analysis compared, among the five typologies, which is the maximum area of influence reached by the lowest air temperature and the highest specific air humidity present simultaneously in all scenarios. The results showed that the spatialization of the green wooded area promotes different areas of influence on the simulated space.
