About the Company

A major multinational conglomerate with over $100 billion in revenue and $80 billion market cap as of 2024, specializing in infrastructure management and operations. The organization manages 7 airports across multiple regions through 10 business verticals spanning transportation hubs, industrial facilities, and real estate development. With over 43,000 employees across all business verticals, the company focuses on modernizing legacy infrastructure using cutting-edge technology to improve operational efficiency and customer experience while maintaining its position as a leading infrastructure operator.

Problem Statement

Critical operational challenges threatening manufacturing efficiency

Manual operation inefficiencies Time-consuming physical AHU power-ups and shutdowns across sprawling airport facilities causing delays and human error risks
Energy optimization gaps Significant energy wastage from delayed AHU operations and lack of weather-based intelligence leading to suboptimal performance
Limited fault visibility AHU troubleshooting and anomaly detection only occurred during manual operator checks approximately once per shift, causing extended downtime
Ambient control variability Difficulty maintaining optimal conditions based on fluctuating occupancy levels linked to flight schedules and varying space utilization patterns
Operational resource strain Heavy manpower dependency for HVAC management reducing team efficiency and increasing operational costs
