Summary
Extends the classic ASHRAE stack-effect relation to estimate buoyancy-driven airflow both through naturally cooled buildings and through passive air collectors, with agreement against previously published results. The analysis indicates that natural convection can meaningfully supplement cooling of small buildings with internal heat loads, and that solar chimneys using deeper air channels than standard collectors can boost this cooling further.
