International Airport

EnergyCAP SmartAnalytics helped one of the busiest airports in Europe achieve its target to cut energy use by a third by 2020. EnergyCAP SmartAnalytics’ one-meter solution was deployed on June 2012 to monitor in real-time the 13 air handling units of the Departure Hall.

Installation setup

A 3-phase electricity meter was wired to the main incomer of the distribution board, powering up the 13 AHU components. Rogowski coils allowed the metering solution to be deployed within 30 minutes and facilitated clamping on the double-fed power supply. The sampling frequency was set to trigger meter readings every 10 seconds and immediately forwarded to EnergyCAP SmartAnalytics Cloud servers via 3G for real-time AHU breakdown. A one-hour profiling phase concluded the installation in less than 2 hours.

EnergyCAP SmartAnalytics insights

1. Variable speed drives do not affect load demand (The customer had no tool to configure variable speed drives efficiently)
2. Significant nighttime load and no off period during daytime (EnergyCAP SmartAnalytics identified major issues with AHU variable speed drives)
3. Four main electricity consumers were immediately identified (The customer needed to be made aware of individual cost contributions)
4. Equipment failure and consumption anomalies are undetected (Customer had no tool to get daily notifications and real-time alerts)

The Results

Fine-tuning of variable speed drives through EnergyCAP SmartAnalytics system produced overall 30% reduction in power consumption and over $5000 in savings within 2 months.
