Análise do conforto térmico proporcionado pelo sombreamento de duas espécies arbóreas sobre edificações

Abstract

The present study aims to analyze the thermal comfort provided by the shading of two tree species: Grevilha (Grevillea robusta A. Cunn ex R. Br) and Sibipiruna (Poincianella pluviosa var peltophoroides (Benth) LP Queiroz) on buildings in Federal Technological University of Paraná - Dois Vizinhos. For the study, five individuals of each tree species. Assessments of individuals and environmental variables were held in four different times, 9am, 12pm, 15pm and 18pm every 15 days for 3 consecutive days in the summer fall and winter seasons, and these measurements were carried out in full sun, under the tree in an open environment and in the projection of the shadow on the building, and 6 individuals of each species influence in 7 buildings, the statistical analyzes were performed by Duncan test at 5% error probability in Assistat program, which is conducted to compare averages of the data obtained. It can be said that the Sibipiruna showed an area of increased shading that Grevilha during the summer and fall. It was concluded that the Sibipiruna presented in all the seasons most pantry area comparing it to the Grevilha. The cup format influences the comfort, with the best rounded crown for the summer and pyramidal in winter. However, the species with the highest number of positive variables inside and outside the building was Sibipiruna.
