Abstract

Abstract

En 中文
• LES resolves near-building AC heat dispersion with facade geometry details. • Subtle façade-scale geometric variations markedly alter the AC heat accumulation. • Protrusion of AC outlets promotes plume detachment and lowers façade temperature. • External vertical shading strongly influences pedestrian-level hot zone. • Extra parapet walls intensify near-façade heat accumulation.
