HVAC layout for building for ENPRO Industries and Flipkart

1. Case Studies on HVAC Layouts Flipkart HQ (Bangalore) & ENPRO Industries HQ (Pune)

2. Case Study 1: Flipkart HQ, Bangalore • Campus: 837,279 sq. ft. at Embassy Tech Village • Challenge: Inconsistent hot & cold spots, no BMS, manual AHU operation • Solutions Implemented: - Dynamic Airflow Balancing (DAB) - Dynamic Chilled Water Balancing (DCWB) - Indoor Air Quality Monitoring (IAQ) - Facilisight (cloud-based monitoring) • Products: 1,063 SmartNodes, 216 HyperStats, 60 CCUs • Results: 27% energy savings, 66,549 kWh/month, 60% reduction in complaints • Achievements: UL Certification for IAQ, CO₂ reduction of 711.4 metric tons

3. Case Study 2: ENPRO Industries HQ, Pune • Office Building: 4,184 sqm, LEED Platinum certified • Climate: Warm & Humid zone • Passive Design: North-South orientation, shading devices, AAC block walls • Cooling Strategies: - Indirect–Direct Evaporative Cooling (65%) - VRF System (22%) - Earth Air Tunnel (12%) - Split AC (1%) • Energy Performance: 82.85% savings vs BEE 3-star building • Payback: 2 years, ROI of 50% in Year 1 • Occupant Comfort: 9.3% thermal discomfort, overall high satisfaction

4. Comparison of HVAC Approaches Flipkart HQ: • Retrofit-friendly smart controls • Focused on automation, energy dashboards • Centralized chilled water & airflow balancing ENPRO Industries HQ: • Mixed-mode low-energy cooling • Heavy reliance on passive + renewable design • Combination of VRF, evaporative cooling & EAT → Flipkart: Technology-driven retrofit → ENPRO: Integrated design for near Net Zero
