Resumen

Este estudio evalúa comparativamente el comportamiento térmico de un parrón y una malla de sombreo como estrategias de acondicionamiento de espacios exteriores intermedios en clima templado. Se desarrolló un experimento in situ en la ciudad de Parral, Chile, mediante mediciones ambientales durante 14 días de verano, con un enfoque exploratorio. A partir del registro de temperatura del aire, humedad relativa, velocidad del viento y temperatura de globo, se calcularon la temperatura radiante media y el índice UTCI entre las 11:00 y las 16:00 h. Los resultados evidencian un mejor desempeño del parrón, con valores menores de UTCI y de temperatura radiante media que los de la malla. La mayor diferencia entre ambas condiciones se observó en este último parámetro, con variaciones diarias de 2,6 a 4,3 °C. Se concluye que el parrón constituye una estrategia pasiva más efectiva para mejorar el confort térmico exterior.
