Energy saving strategies applied to a data center in Japan
Overview:
The case study findings encompass short and long-term initiatives with measurable potential to reduce operational expenditure (OPEX) and improve overall energy performance.
Organization profile:
Average monthly energy usage: ~3GWh
Annual electricity bill: ~$3.8M
Size: Over 300 customers hosted at single data center
Location: Tokyo, Japan
Method and results:
- AI-based energy performance diagnostic (Power Usage Effectiveness and daily load concentration, high density rack analysis, customer segmentation and rack usage intensity analysis)
- Multi-factor improvement plan design (improved airflow, temperature control, idle rack optimization)
- Ultra fast ROI (<6 months)
