Este estudo avalia comparativamente o comportamento térmico de um pergolado com parreira e de uma tela de sombreamento como estratégias de condicionamento de espaços exteriores intermediários em clima temperado. Desenvolveu-se um experimento in situ na cidade de Parral, Chile, com medições ambientais ao longo de 14 dias de verão, adotando-se uma abordagem exploratória. A partir do registro da temperatura do ar, da umidade relativa, da velocidade do vento e da temperatura de globo, calcularam-se a temperatura radiante média e o índice UTCI entre 11h e 16h. Os resultados evidenciam um melhor desempenho do pergolado com parreira, com valores mais baixos de UTCI e de temperatura radiante média em comparação à tela. A maior diferença entre as duas condições foi observada neste último parâmetro, com variações diárias de 2,6 a 4,3 °C. Conclui-se que o pergolado com parreira constitui uma estratégia passiva mais eficaz para melhorar o conforto térmico exterior.
