CFD-Driven Passive Cooling and Renewable Retrofits for Nearly Net-Zero University Buildings in a Hot–Humid Climate

Mohammed M. Gomaa, Diana Hassan Mardenli, Alaa Alaidroos, Djihed Berkouk et al.

Short summary

A retrofit framework integrating HVAC optimization, passive cooling (including PDEC), and renewables transformed a Jeddah university building into a nearly NZEB, cutting energy demand 58% before PV deployment and reducing life-cycle costs from 7.51M to 3.13M SAR over 25 years.
