Case Study: Dublin Airport achieves 30% energy reduction and €3,900 savings with EnergyCAP

Dublin Airport - Customer Case Study

Dublin Airport, one of the ten busiest airports in Europe handling about 60,000 passengers per day, needed to cut energy use by a third and had limited visibility into air handling unit (AHU) performance and faults. To tackle this, Dublin Airport engaged EnergyCAP, which deployed a one‑meter real‑time monitoring solution across the 13 AHUs in the Departure Hall to provide detailed submetering and fault detection.

EnergyCAP installed a three‑phase meter with Rogowski coils, sampling every 10 seconds and sending data via 3G to cloud servers for real‑time AHU breakdown, alerts and profiling; analysis revealed ineffective variable speed drives, significant nighttime loads, and the four main electricity consumers. Fine‑tuning the variable speed drives through EnergyCAP’s system produced a 30% reduction in power consumption and achieved €3,900 in savings within two months, while providing ongoing visibility and real‑time notifications.
