Energy Efficiency

The goal of Green Labs Energy Efficiency is to reduce energy consumption within labs, educate on proper energy saving techniques, and provide resources/tools for energy efficiency.

In a 2012 energy assessment, laboratories made up 47% percent of total electricity usage on campus. Green Labs has since initiated energy saving campaigns and resources to monitor and reduce energy consumption:


Energy Statistics


Total Campus Electricity: 50,464,000 kWh/year
Total Lab Electricity: ~24,000,000 kWh/year

Monitored Building Consumption:

Biomed: 2,305,077 kWh
Earth & Marine Sciences: 4,505,294 kWh
Physcial Sciences Building: 3,669,368 kWh
Sinsheimer: 3,368,357 kWh
Thimann: 2,111,479 kWh


Best Energy Practices

  • Keep the fume hoods sash shut or lowered when not in use. Add date fume hood sticker was installed.
  • Practice energy conscious experiments (i.e. not refluxing overnight, not running an oven to dry a sample over the weekend, unplugging hot plates, and incubators when not in use).

  • Use appropriately sized containers for ice, dry ice, and liquid nitrogen (oversized containers waste material and energy, so only take the amount you need).

  • Post and follow any exit procedure reminders to practice energy savings (i.e. turn off lights, unplug acceptible equipment, click off power strips, etc).

  • Unplug unused electronic devices.

  • Use compact fluorescent light bulbs or LEDs in all applicable light fixtures.

  • Use lighting strategies (i.e. task lighting, bi-level lighting).

  • Make power strips easily accessible.

  • Don't use screen savers.

  • Use smart strips/ecostrips or any other energy efficiency power strip device (sensored powerstrips that may turn off automatically when not in use).

  • Have an annual lab cleanup day that includes thawing freezers.

  • Use EnergyStar (or other high-efficiency) appliances.


Shut the Sash

Fume Hood Shut The Sash

Fume hoods are one of the most energy consuming pieces of equipment within a laboratory. In our Shut the Sash Campaign, we asked labs to shut or lowered fume hood sashes when not in use. Doing this will decrease the amount of air suction and drastically improve energy efficiency.


Freezer Clean-Out and Thawing


Reasons to clean-out and thaw your freezer:

  • Minus 80 freezers are the largest single equipment energy draw from a plug load.

  • Cleaning out a labs freezer will save money, energy, and space.
  • Many samples can be stored in minus 70 degree freezer temperatures without impacting longevity.
