Inaugural Freezer Challenge | WashU's Commuter Platform

Beginning in January 2022, research labs on all WashU campuses are encouraged to assess their cold storage needs, perform regular maintenance, and retire old appliances by participating in the 2022 International Freezer Challenge.

Research labs rely on a wide range of appliances and electronics to complete their research and function on a daily basis. Chances are, labs have at least one -20 freezer, -80 freezer, or even a -150C freezer, if not several of each. These appliances, while vital to research, use significant amounts of energy that lead to greenhouse gas emission. Reducing these emissions by selecting high-efficiency (or Energy STAR) appliances when purchasing is a great first step, but proper maintenance plays a critical role in reducing emissions over the lifespan of the unit – whether high-efficiency or standard efficiency.

When freezers and refrigeration units are not managed or maintained properly, these emissions increase from the machine struggling to maintain internal temperatures and running more than necessary. Add in the risks of refrigerant leaks, and these mishaps become a serious risk to our environment. More>>
