Thermal performance of a vegetated roof on a fiberglass security booth

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,...

Desempenho térmico Cobertura verde Guarita de fibra de vidro Curitiba-SP. 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. Neste trabalho é apresentada a avaliação do desempenho térmico de cobertura vegetada sobre guarita de fibra de vidro para primavera-verão de 2018 em Curitiba/PR. Compararam-se guaritas em condição experimental (ME) e controle (MC) para três configurações de cobertura (substrato; substrato e vegetação; substrato, vegetação e tela de sombreamento), com e sem sombreamento de janelas. A análise de conforto e estresse térmico seguiu parâmetros normativos de índice de bulbo úmido e temperatura de globo - IBUTG e temperatura efetiva - TE. A envoltória de fibra de vidro interferiu na temperatura do ar nos dois módulos, sendo a diferença na temperatura interna do MC e ME de apenas 2 °C. Entretanto, quanto às temperaturas de superfície sob a cobertura, o sistema de cobertura vegetada do ME ofereceu amortecimento e atraso térmico, atingindo uma diferença de até 12 K relativamente ao MC. Na comparação ME vs. MC, não se verificaram horas em estresse por calor no IBUTG, porém os valores de TE, em sua maioria, migraram para a condição de conforto, com a cobertura vegetada. Outra técnica explorada neste artigo é baseada na análise termográfica. Os resultados mostraram desempenho térmico superior do ME se comparado ao MC, confirmando as medições pontuais de temperatura de superfície.
