Passive Solar & Computational Fluid Dynamic (CFD) Airflow Modeling
Advanced digital aerodynamic simulation of natural cross-ventilation, stack-effect cooling, and envelope thermal performance.
Harnessing the natural movement of air allows a residence to remain cool and fresh while reducing air conditioning dependence. Rowui uses Computational Fluid Dynamics (CFD) airflow simulation to model how prevailing breezes move around and through the residence. We optimize window apertures, orient double-height thermal chimneys to induce natural stack-effect cooling, and calibrate building overhangs for optimal solar comfort.
