Location	Multiple locations across Europe, expanding with further sites both in Europe and globally
Electricity consumption % for cooling	40%
Customer's objectives	Energy efficiency, improve power usage effectiveness (PUE), coefficient of performance / energy efficiency ratio (COP/EER) Create baseline to certify energy savings and ensure compliance with ISO 50001 Reduce the number of failures like blocked expansions valves and compressor problems Control of chiller performance, looking into the difference between the different chillers in operation Provide a specific tool to their facility management to acquire in-depth insights of the chillers and plant performance Improve preventive maintenance Verification and validation after maintenance Leak detection, immediate interception of leaks on the refrigerant circuits
EEHub solution	Through EEHub Connect we performed an in-depth site survey, seamlessly connecting multiple data center buildings and integrating 50 air-cooled chillers, pumps, and computer room air handler (CRAH) units to our digital service platform EEHub Digital. A customer-specific dashboard on EEHub Digital mirroring the Customer's installed base was provided to the facility management to monitor the plant performance. For continuous improvement, the Customer has chosen EEHub Optimize
Outcome	The initial findings focused on enhancing energy efficiency by changing the control strategy. With the first 30 days of the start-up period implementing EEHub Connect further optimization opportunities were identified. By adjusting the condenser temperature and increasing waterflow, we achieved savings exceeding 8%. We also found out that the economizers on the chillers are not used. Due to the EEHub Optimize we expect more savings by optimizing the control strategy and activate the economizers Summary of results: Increase in Coefficient of Performance (COP) Adjusted condenser temperature Increased pump speed Expected result due the EEHub Optimize: Plant optimization (economizer) Preventive maintenance improvement Predictive maintenance improvement - avoided the failure on the reported compressor, avoiding out-of-service and ancillary costs. Predictive gas leak detection We are currently adding 25 chillers, marking the next phase in our continuous efforts to advance energy efficiency through EEHub Connect and EEHub Optimize
Customer's feedback	"The expertise of EEHub's engineers and technicians is a valuable asset in optimizing our plants and achieving maximum efficiency on cooling plants. This solution provides visibility into 'hidden data' that can lead to an important reduction in the number of failures by implementing a part of predictive maintenance that is not currently present. It is believed that the analyzed platform has already led to very good concrete results and that the short period of analysis still hides a lot of untapped potential."
