Solar chimneys can be employed in buildings for natural ventilation, cooling, or heating of the building envelope, hence saving energy.

While heating the whole left wall induced more flowrate than heating the whole right wall, heating part of the left and the right walls resulted in peak performance at specific portions of the right wall heated from the bottom or the top of the channel.
