Performance Assessment of Sensor-Controlled Windcatchers in Hot-Arid Climates

Abstract

This study evaluates a four-sided windcatcher with motorised dampers in a Yazd residence over twelve months. Measured temperature, humidity and airflow data are compared with computational fluid dynamics simulations. Results show that active damper control increases night-time air change rates by up to 40 per cent. The findings offer guidance for designing hybrid ventilation systems in desert regions.
