Sustainabiity: Green Tip of the Month
Green Tip of the Month: Lab Efficiency
Be cool about refrigeation
Before you open a -80°C freezer, know the location of what you’re taking out so you don’t waste energy while the door is open — have an updated inventory sheet (and emergency contact info) near the door. Clean the filters of the -80 freezers annually, and defrost -80 and -20 freezers twice a year. Make sure the freezers are about 10 inches away from the wall at all times so the air can recirculate. Turn off refrigerated centrifuges when not in use.
Small steps can save big on energy
When they aren’t in use, shut the sash of biosafety cabinets (including all recent models of Baker hoods) and of chemical hoods, or turn them off completely — this is a major source of energy waste. Turn off the lights of your bench and your lab if you are the last one to leave at the end of the day. And turn off lights of a cold room when you leave. If you can control your thermostat, keep lab temperature in the mid-60’s when at work, and 50 to 60ºF while away.
Share the wealth
Manage lab inventory closely so you don’t waste resources on oversupply or things you don’t need. And instead of throwing out supplies and devices when you’re through with them or if you have extras, post them on Rockefeller’s Classifieds (but remember chemicals are prohibited).
Did You Know?
Of the university’s total electricity costs, 20% is attributable to -80°C freezers alone.
