Many valuable scientific research samples are stored in ultra-low temperature (ULT) freezers, each of which consumes as much energy as a single family home. With approximately 1000 ULTs on campus, cold storage continues to be a major target for Green Labs energy conservation efforts.
Building on past pilot studies, this year’s Chill Up Challenge encouraged researchers to adjust the temperature of ULT freezers. An increase of 10oC reduces equipment energy consumption by 20 per cent on average. This action is safe for many research sample types, increases freezer lifespans and contributes to equipment cost savings and waste reduction.
An impressive 58% of Michael Smith Laboratory researchers now have freezers set to the energy saving temperature. The department is saving 38,000kWh of electricity each year, equivalent to the consumption of 100 home chest freezers.
