Summary
Scaled laboratory tests examine a passive scheme that pairs radiative cooling with a solar chimney to drive airflow through an underground space. The combination steepened the temperature difference along the flow path and outperformed the chimney alone. Gains slowed beyond a heating temperature of about 50 °C, and heating the middle-lower chimney section gave roughly 41% higher air velocity than heating near the top.
