| Summary: | The thermal performance of a vegetated roof in a fiberglass security booth was evaluated for spring-summer of 2018 in Curitiba/PR. An experimental (EM) and a control module (CM) of two equal security booths were compared for three roof configurations (substrate; substrate and vegetation; substrate, vegetation and shading mesh) and two window conditions (shaded and unshaded). Comfort and thermal stress analyses followed normative parameters of wet-bulb globe temperature (WBGT) and effective temperature (ET). The fiberglass envelope interfered with the air temperature in both units. The indoor temperature in MC and ME differed by 2°C. However, the vegetated cover system of the ME offered fluctuations reduction and thermal delay, reaching a peak difference of 12K when compared to MC. Hours in thermal stress were not identified in CM and EM for WBGT, though with the vegetated cover hours in thermal comfort were generally enhanced in terms of ET. Another technique explored in this article consisted of a thermographic analysis. Results showed higher thermal performance of EM relative to CM, confirming the spot surface temperature measurements. |
