Proposed Cowlitz PUD Airflow Management Pilot Presented at the RTF IT Subcommittee March 5, 2013 Kerstin Rock, Director Michelle Lichtenfels, Senior Program Manager

Pilot Design Pilot Objectives Pilot Scope –Assessment –Customer Implementation –M&V Questions 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 and Temperature Management Measures

Customer Implementation Install blanking panels Add VFDs to supply fans Add partitions Remove airflow obstructions Move floor tiles Plug holes in floor tiles Turn off redundant CRACs Rearrange servers Increase SATs Coordinate humidity setpoints 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
