The 2017 Freezer Challenge took place between January and May. This year’s challenge has already completed, but don’t worry- there will be another Freezer challenge next year!
In 2017, an average of 7,000 kWh/year ($840/year at 12 cents/kWh) was saved per participating laboratory!
2017 Participating laboratories:
Are you up for saving energy on your lab’s cold storage? If your lab uses ultra-ultra low temperature freezers (-150C), ultra-low temperature freezers (-80C), lab freezers (-70C to -20C), refrigerators, or cold rooms, you can decrease greenhouse gas emissions and earn points simply by taking the actions listed below.
The International Institute for Sustainable Laboratories (I2SL) and My Green Lab have partnered together to hold the first annual North American Laboratory Freezer Challenge.
Laboratories earn 1 point for each action taken below per refrigeration unit in the freezer challenge!
- Good Management Practices
- Defrosting freezers
- Cleaning out freezers and refrigerators
- Inventorying samples
- Converting to liquid nitrogen storage
- Storing samples at high density
- Temperature Tuning
- Adjusting the set point of ultra-low temperature freezers
- Storing samples at appropriate temperatures
- Retirements & Upgrades
- Retiring old refrigeration units
- Replacing older refrigeration units with energy-efficient units
- Cutting-Edge Practices
- Sharing refrigeration space with a colleague
- Barcoding samples
- Trying/adopting room-temperature sample storage
Labs will also earn points for sharing information about their own best practices regarding sample storage and inventory.
