2017 Freezer Challenge

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:

  • Kovar
  • Lynch
  • Bishop
  • Thinakaran
  • Sosnick
  • Horne-Badovinac

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!
