This paper aimed to investigate, both by simulations and experiments, the report from the passengers that use the bus stop located in Praça dos Voluntários, next to the Municipal Market in São Carlos, in the countryside of São Paulo state, Brazil. Since the installation, users have claimed an excessive increase in the temperature in the region below the covering. We started characterizing in the laboratory the optical properties for the polymeric material used for the structure, and we simulated refraction and reflection effect at the covering surface. From the experimental point of view, we designed, fabricated and tested a low-cost monitoring station with the purpose of collecting in-situ data to correlate our model with the measurements. Once installed the station, the measurements showed a good agreement with the theoretical optical model developed for the architectural structure. Moreover, we showed that also if the material is probably the main responsible for influencing excessive heat and temperature increase, the shape and geometry amplify the studied optical phenomena. The reflection and the refraction at the covering add up getting worse the thermal situation and compromising the role of the roofing at the bus stops: to protect the passengers from the sunlight and to reduce the heat detected above the architectural structure.
