Downdraught evaporative cooling wind-towers

What is it about?

This article looks at a new breed of cooling wind-towers, which artfully blend the traditional principles behind a wind catcher with today’s technological advances. It tackles a study case where cool-towers are designed to cool outdoor courtyards across the Princess Nora Bint Abdul Rahman University (PNU) in Riyadh, Saudi Arabia. Using CFD, we find that the cool-towers are capable of generating a relatively comfortable zone in the courtyard.
