A southern regional hospital preparing for accreditation needed to confirm that pressure gradients and airflow organization across its ORs and ICUs met ASHRAE 170. SYE completed verification and optimization of 8 operating rooms and the ICU during non-surgical days.
Some ORs dated to an earlier construction era; as-built drawings diverged from current ductwork, making supply/return ratios hard to locate quickly. Post-COVID, several rooms had been repurposed into negative-pressure isolation, requiring the pressure-gradient logic to be revalidated.
Room-by-room mapping of supply/return diffusers with velocity and volumetric flow measurements
ASHRAE 170-based calculation of air changes per hour (ACH) and pressure differential thresholds
Smoke testing to verify airflow direction and flag recirculation points
Recommended ductwork modifications and VAV adjustments, plus a phased remediation plan
