Proposed Cowlitz PUD Airflow Management Pilot Presented at the RTF IT Subcommittee March 5, 2013 Kerstin Rock, Director Michelle Lichtenfels, Senior Program Manager Agenda • Pilot Design • Pilot Objectives • Pilot Scope – Assessment – Customer Implementation – M&V • Questions 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 regionspecific 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 and Temperature Management Measures 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 Customer Implementation Turn off redundant CRACs Rearrange servers Increase SATs Remove airflow obstructions Add partitions Install blanking panels Plug holes in floor tiles Coordinate humidity setpoints Pilot Project Estimates: Implementation Cost: Simple Payback: $13,000 2.6 years Move floor tiles Add VFDs to supply fans M&V and Project Completion • End-Use Metering Protocol – Aligned with IPMVP Option B Questions?
