What is Sustainability?
“Meeting all the needs of the present without compromising the ability of future generations to meet their own needs”
![Page 6: Greening Your Lab Responsible Conduct of Research Duke University October 8, 2013.](https://reader035.fdocuments.net/reader035/viewer/2022062517/56649f385503460f94c549c2/html5/thumbnails/6.jpg)
Impacts of Research LabsEnergy
Labs are 5 times more energy intensive than other campus spaces, on average.
Cost to operate a fume hood at Duke is $5000 per year. Same cost as running 3.5 houses.
Cost to operate an ultralow freezer at Duke is $1200 per year.
