Agenda
AFM Pilot Design
• Scaled for small to medium-sized data centers
• Typically focused on identification of a series of simple and low- or no-cost measures related to airflow and thermal optimization
• Implementation typically results in higher supply air temperature and reductions in airflow for improved energy efficiency
– Reduce HVAC system airflow to match IT equipment airflow and higher supply air temperatures
Pilot Objectives
1. Savings-generating pilot
2. Identify & facilitate implementation of energy-focused airflow improvements in the data center
3. Pilot AFM approach and collect region-
specific data– Test tools, protocols, and processes
4. Queue up airflow solutions for the utility environment
Pilot Scope• 3 sites (commercial and/or
industrial)
• Comprehensive assessment of data center
• Detailed energy savings report &
suite of recommendations
• Project implementation support• Follow-up verification of
measures
• Develop case study
AFM Assessment
Airflow Add partitions
Add strip curtains
Reposition floor tiles
Plug holes in floor tiles
Remove airflow obstructions
Blank off empty racks and cabinet / rack gaps
Add VFDs to supply fans
Turn off redundant CRACs
Improve RA pathway
Rearrange servers
Temperature
Increase SATs
Humidity
Coordinate humidity setpoints
Airflow and Temperature Management Measures
Customer Implementation
Install blanking panels

Pilot Project Estimates:
Implementation Cost: $13,000 Simple Payback: 2.6 years
M&V and Project Completion
• End-Use Metering Protocol
– Aligned with IPMVP Option B
