Ventilation using solar chimneys (tool: Ansys Fluent)
Wind Velocity
Wind velocity in the region and courtyard at 5m height
Wind velocity in the region and courtyard at 10m height
The typical wind direction in Phoenix goes from the East
to West and the wind speed rarely exceeds 7 m/s. The
courtyard acts as a buffer to harness the oncoming wind
from the East and aims to cool the air using evaporative
cooling techniques through a water fountain, foliage and
shade. The harnessed and cooled air is then released
into the indoor spaces through the intermediate channels during the hot summer months (right). The solar
chimneys then induce the stack effect to release the
heated indoor air into the atmosphere through outlets at
the top of the building.
