The aim of this study was to evaluate thermal comfort level in distorted small-scale models of green-roofs submitted rural shelters. The study was carried out during April 1 to May 31 2015, lasting 61 experimental days, at the experimental area of Agricultural Engineering Department, from (UFRPE), in Recife-PE. Meteorological variables of air temperature (ºC) and air relative humidity (%) were recorded inside the small-scale models dataloggers. While the same variables were recorded outside the shelters using an automatic meteorological station. In order to perform thermal analysis of the small-scale models green roof, it was used thermal images from the internal roof surface obtained by a thermographic camera. It was used a completely randomized design, in which four treatments were used, green roof of chanana (Turnera subulata) (TVc), margaridinha (Sphagneticola trilobata) (TVm), salsa (Ipomoea asarifolia) (TVs) and roof of fiber cement (Tfib), in which four replicates, summing up to 16 small-scale models. Tukey’s test (p < 0.05) was used in order to compare treatments’ means. Green roofs (TVc, TVm e TVs) promoted air temperature reduction inside the small-scale models in (0,71 °C; 0,19 °C e 0,35 °C) and internal surface temperature reduction inside of coverages in (1,5; 0,8 e 0,8 oC), compared with to the roof of fiber cement (Tfib). Small-scale models submitted green roof of chanana presented the best thermal performance and air temperature reduction inside its shelter.
