Pinnacle Infotech transformed its 137,593 sqm Madurai Campus into a benchmark for smart, sustainable management. The challenge was integrating disparate systems for real-time efficiency and predictive maintenance across the 2,000-seat facility. Using Bentley iTwin and iTwin IoT, they built a Digital Twin, integrating over 1,500 sensors and AI for anomaly detection and energy forecasting. This digital solution achieved remarkable results: 20% reduction in maintenance costs, 30% reduction in maintenance time (saving 8,000 hours/year), and INR 50,00,000 in annual OpEx savings. Environmentally, the project cut 300 kg of CO2 annually and reduced paper use by 80%, demonstrating a commitment to Climate Action and the Energy Transition through optimized resource management. The Digital Twin ensures long-term operational excellence and resource efficiency.
