The thermogram corresponding to the lowest gradient value, at 5:00 PM, presented in Fig. 8c, shows the window glass marked by purple color (cold) representing decreasing radiation emitted by the sun at dusk, thus also causing thermal gradient to decrease, even with glass emissivity difference. It is concluded that during rainy season, high values of thermal gradients area present between areas affected by humidity and sections without anomalies. Additionally, the best reading period is that when sun rays hit the subject wall, which is the main contribution factor at the study period and generation of these temperature differences.
