What was presented about ULT freezers at the I2SL conference in 2013? Key Insights on Sustainable Lab Practices

At the 2013 I2SL conference, the Centers for Disease Control and Prevention (CDC) shared a significant case study involving the adjustment of 60 ultra-low temperature (ULT) freezers from -80°C to -70°C on one of their campuses. This presentation highlighted practical energy-saving measures in laboratory settings without compromising sample integrity, demonstrating how small operational changes can lead to substantial sustainability gains in scientific facilities.

Key Points Explained:

1. CDC's Energy Efficiency Initiative
   The CDC implemented a temperature adjustment program for 60 ULT freezers, raising their setpoints from -80°C to -70°C. This change was presented as part of broader sustainability efforts in laboratory environments.

2. Temperature Adjustment Rationale

   • Energy Savings: Higher operating temperatures reduce compressor workload, leading to significant energy reduction
   • Sample Integrity: Research showed many biological samples remain stable at -70°C, making this a viable option for certain collections
   • Equipment Longevity: Reduced thermal stress on freezer components extends operational lifespan

3. Implementation Scope
   The project was conducted at scale across one CDC campus, demonstrating:

   • Feasibility of large-scale temperature adjustments
   • Potential for institutional energy policy changes
   • Compatibility with existing laboratory workflows

4. Conference Context
   Presented at I2SL (International Institute for Sustainable Laboratories), this case study:

   • Addressed sustainable lab equipment practices
   • Provided measurable data for energy-conscious lab planning
   • Offered a replicable model for other institutions

5. Broader Implications
   This presentation contributed to ongoing discussions about:

   • Re-evaluating historical temperature standards
   • Balancing scientific requirements with sustainability
   • Creating tiered storage strategies based on sample needs

The CDC's presentation remains relevant today as laboratories worldwide continue seeking ways to reduce their environmental footprint while maintaining research quality—showcasing how thoughtful equipment management can yield both ecological and operational benefits.
