Intelligent Energy Management Made Simple
Cooling problems• Server manufacturers specify inlet air temperatures
• Conventional controls don’t measure it
• Overcooling
• Inefficiency
• Hot spots
Cooling control is difficult• Open plan design
- All cooling units affect all areas
• Redundant cooling units - Can lead to “fighting”
• Custom control software is expensive and unreliable- Can’t have a PhD commission every datacenter
What we do
Insight
Analysis
Control
< 2yr ROI
How we do it• Measure inlet air temps
• Supervisory control
• Learning algorithms
• Installed in days
Wireless Module
Temperature Probes
Recommended deployment strategy
• Install controls first- Immediate automated energy savings
- Excellent complement to IT-side best practices
• Persistent Commissioning™ - Determine where and how to improve
- Cost effective deployment of best practices

Case Study 1 – Franchise Tax Board
• The Data center:- 10,000 SF- 12 CRAH’s (22 tons each)- 40% built out
• The solution:- 50 wireless inlet server temperature sensors- 4 VFDs installed- Re-arranged tiles- Reset setpoints of CRAHs- Automatic start-stop of CRAHs
Case Study 1 – Energy Savings• Software shut off 6-8 CRAH units
- All temperatures within ASHRAE recommended range
• 310,000 kWh/year saved- 245,000 kWh/year fan savings- 65,000 kWh/year chiller savings
• $27,900/year saved ($0.09/kWh)
• 58% reduction in fan energy usage
• 13.4% reduction of total datacenter energy usage
Case Study 2 – Bay Area• The Data center:
- 5,000 SF- 6 CRAH’s (22 tons each)- 130 racks
• The solution:- 48 inlet air temperature sensors- 6 VFDs with wireless controls- No other efficiency measures taken- One-day installation
Case Study 2 – Energy Savings
• 300,000 kWh/year saved- 218,000 kWh/year verified fan savings- 82,000 kWh/year estimated chiller savings
• $27,000/year saved ($0.09/kWh)
• 80% reduction in fan energy usage
• 17% reduction of total datacenter energy usage
Customer perspective
Summary• Excellent ROI from supervisory cooling control
• Quick and non-intrusive installation
• Enables cost-effective application of best practices
• Excellent complement to IT-side best practices
