Resumen
Urban climate studies have shown that, in temperate as tropical areas, local
climate change is associated with the effect of energy conversion the urban area,
influenced by it morphology, thermal properties of materials surfaces constructed
and by anthropogenic heat production. These modifications result in phenomena such
as the urban heat island, which is characterized by a higher air temperature in urban
environment, compared to less urbanized neighboring regions. The overall objective
of this research is to evaluate urban heat islands mitigation strategies from case study
of the Federal University of Mato Grosso campus, located in Cuiabá-MT. The effects
of the strategies cool roof, green roof, fresh pavement and vegetated areas increment
variables air temperature (°C) and relative humidity (%) were evaluated. The method
used consisted in simulations using ENVI-met software. Therefore, it was necessary
to collect micrometeorological data to perform model validation and to design five
scenarios: the reference scenario, as found in reality and 4 more scenarios,
contemplating the strategies studied. The evaluation of the effect of these scenarios
was made by difference value of the variable found in the reference scenario and the
scenario with the strategy implemented. All strategies evaluated showed effects on
air temperature (reduction) and humidity (increase) during the two seasons
considered. The highest effect in reducing the average air temperature during the
day, for two study periods was recorded by strategy 3 - cool pavement with 1.20 °C
in the wet period (13h) and 1.96 °C (12h) during the dry period. The same result was
found for the variable relative humidity, which also had the highest effect seen in
strategy 3, with increase from 9.76% for the wet period and 9.34% during the dry
period. It is hoped that with the findings of this research, the study of environmental
comfort for the state of Mato Grosso and the Midwest region is enriched, noting the
role of urban heat island mitigation strategies as soften agents to the high temperature
climates of the mid-sized cities, such as Cuiabá.
