DescriptionThe wind catcher towers at Princess Noura bint Abdulrahman University (PNU) in Riyadh, Saudi Arabia, will be used as ventilation systems for open “courtyard” spaces in several buildings around the university campus. The interior of each of the 30 wind catcher towers has an operable drum at the top for harnessing wind, an internal wind tunnel and fan, and a complex turning vane system to redirect the airflow into the courtyards.
