22% energy efficiency delivered till October 2022, equivalent to INR 108 mn cost savings
Design Interventions
- Redesign consolidating the cooling load from 3 to a single chiller plant room
- Interconnection of block 3 air cooled chiller plant with water cooled chiller plant
- Shifted load of dedicated air-cooled chillers for biomedical equipment to central plant
- Transitioned from diesel to electric based hot water and steam systems
- Move from fixed to dynamic air and water flow controls
- Distributed tertiary pumping systems to optimize pressure delivery
- Laundry dryer panel retrofit to solve existing design flaws
Equipment Interventions
- Replacement of HVAC pumps to double efficiency
- Low approach cooling tower
- Optimum water quality maintenance to maintain low condenser inlet & approach
- Several installation to increase efficiency – 2 condenser pumps, a heat pump, 4225 energy efficient LEDs, 350 BLDC fans, 3 electric boilers
- Energy efficient kitchen burners, flood lights, laundry dryers
- Hydromax for better efficiency of heat pump
Operations Interventions
- Once per month to once per minute analysis of energy consumption
- Deployment of the DeJoule suite of solutions
- Integration of DeJoule to enhance capabilities of existing Honeywell BMS
- Dynamic controls of critical equipment based on custom, evolving logic
- Dynamic chilled water set point optimization based on changing load
- Schedule based to data-based maintenance practices
Project Output
Cooling efficiency improvement of 0.45 kWh/TRH
Cost Saving of INR 108mn till date
