In today’s digital era, the high energy consumption of data centers has become a major challenge. Through the integration of AI-based dynamic precision control and multiple energy-saving technologies—including hot and cold aisle containment, free cooling with outdoor air, and high-efficiency power systems—Delta’s headquarters data center achieved a 16% reduction in Power Usage Effectiveness (PUE).
This accomplishment not only ensures stable and reliable service operations, but also sets a new benchmark for energy efficiency in the industry. The data center has been awarded LEED v4 ID+C Platinum certification, earning a perfect score in the Energy Efficiency category, a testament to Delta’s leadership in sustainable innovation.
The primary challenge for the data center was to achieve energy-saving goals while maintaining stable operations. It was essential to improve the efficiency of power conversion and lighting systems without disrupting ongoing services. When introducing AI-based energy control, the team also faced the challenge of analyzing massive volumes of real-time operational data and seamlessly integrating AI with existing infrastructure. The goal was to ensure that the system could make optimal, data-driven decisions, striking a perfect balance between operational stability and energy efficiency.
By conducting an in-depth analysis of energy data, the team established accurate energy baselines and usage models, identifying potential high-consumption areas and equipment. Performance comparisons were then made based on this data to pinpoint key sources of energy waste. Finally, a comprehensive energy improvement report was developed, detailing the expected benefits of each proposed measure. This report provided energy management personnel with clear, data-backed insights to make informed decisions and optimize overall energy efficiency.
The data center implemented a comprehensive energy-saving strategy centered on AI-driven dynamic precision control, which analyzes real-time data to fine-tune equipment operations. By integrating free cooling systems that leverage outdoor air, the facility effectively reduced the cooling load on air-conditioning units. Additional enhancements included variable-frequency control for chilled water pumps, cooling water pumps, and cooling towers, along with hot and cold aisle containment and high-efficiency LED lighting—all working together to maximize energy performance.
