Thermal impact of a glazed facade in Vitória - ES

development of measurement methodology for analysis of thermal comfort in urban environment

Abstract

The architecture that historically sought to reflect the aspects of their insertion point, is ceding space to a standardized architecture, observed in buildings with their front with reflective glass. However, their unruly appliance in warm climate countries entails significant problems in urban thermic comfort, eventually contributing to the formation of heat islands. In this context, this essay’s objective is to define and validate a microclimatic measurement methodology for evaluating the thermic impact in urban environment, at passerby level, caused by the use of this typology. The methodology consisted in the characterization and mapping os the buildings that had glassed front in the neighborhood of Enseada do Suá, in Vitória/ES, with the definition of a building for solar incidence analysis and of the measurement campaign points, that occurred in a single day using the following tools: tripod, thermos-hygro-anemometer and globe thermometer protected by a meteorological shelter. The results indicated that solar radiation reflected by the glassing, in that locality, may have influenced the urban microclimate, changing the thermal feel experienced by the individual and confirming the effectiveness of the methodology. In that manner, one understands the importance of the continuality of the studies with the proposed measuring to obtain proof of the thermal impact occasioned by the reflective glassed fronts.
