AVALIAÇÃO DAS TEMPERATURAS RADIANTES DE COPAS DE ÁRVORES E SEUS EFEITOS EM SUPERFÍCIES PRÓXIMAS

Abstract

One of the contributions to possible improvements in the quality of life in cities is the planning of urban afforestation that can result in environmental benefits. Afforestation on public sidewalks should be attentive to the choice of suitable species that do not obstruct the passage of passers-by and explore the air space without environmental interference, seeking to promote shaded areas that provide comfort to local users. Planting trees without planning, as well as causing negative ergonomic and spatial impacts, can promote adverse environmental effects. It is assumed, for example, that the increase in the surface temperature of masonry can occur by the reflected radiation of the crowns of the trees, when very close. In this sense, the objective of this work is to evaluate the surface temperatures caused by the reflected radiations of the leaves of the crowns of the trees of a group of species at certain distances, seeking to identify the impacts on nearby surfaces. The methodology applied to this research will include bibliographical review on the subject, establishment of criteria for selection of tree species to be evaluated, analysis of the compositions and spatial arrangements of arboreal individuals, as well as measurements in loco that measure by pyranometers the average irradiance over the treetops. Finally, the data collected will be inserted into the ENVI-MET software database to simulate the performance of new tree arrangements, looking for results of optimized deployments, aiming to propose more thermal comfort for cities.
