Shading-solar-chimney: experimental evaluation and by CFD/EnergyPlus simulation of a ventilation device

Summary

Develops a sun-shading element that doubles as a solar chimney to naturally ventilate school classrooms, assessing it with building-energy and CFD software plus on-site measurements. The two simulation tools disagreed markedly, while field data confirmed the CFD results; the device lowered operative temperature, met indoor air-renewal recommendations and reduced glare, notably under overcast skies.
