Randy SmithManager, Department of Biology

Convener, Green Labs at Duke

Green Labs at Duke is a group of faculty, staff and students dedicated to promoting sustainable practices in

Duke University’s research and teaching laboratories.

Overview:• Define sustainability• Impacts of research labs• Mitigating the impacts through best practices• Duke Green Lab Certification• Small group discussion of individual labs• Regroup – discussion of issues• Current projects

What is Sustainability?

“Meeting all the needs of the present without compromising the ability of future generations to meet their own needs”

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.

Green Lab Certification

The Green Lab Certification Program was jointly developed by Sustainable Duke and Green Labs at Duke. We would like to recognize the work of the Office of

Environmental Stewardship and Sustainability of University of California – Davis, LabRats of the University of California - Santa Barbara, Higher Education

Environmental Performance Improvement of the UK and Yale University Office of Sustainability for inspiration and some of the content of this certification program.

Green Lab Certification

Three levels – Bronze, Silver and GoldPrerequisites plus points Points as a percentage of applicable pointsPrerequisites only = BronzePrerequisites plus 50% of applicable points = SilverPrerequisites plus 90% of applicable points = Gold

Green Lab Certification Process

• Review Guide to Certification Checklist• Complete online Certification Checklist• Certification

Green Lab CertificationManagement and Training

• Think about your lab practices

• Participate in Green Labs at Duke (at some level)

• Communicate within your lab

Green Lab CertificationEnergy Conservation

• Fume Hood – sash closed and hood certified

• Cold Storage – freezers maintained, contents relevant, number of small units minimized

• Equipment use maximized and turned off when not in use

Green Lab CertificationWater Conservation

• Eliminate single pass cooling

• No water powered aspirators

• Minimize purified water use

Green Lab CertificationChemical Storage and Use

• OESO lab audit

• Up to date chemical inventory

• Minimize chemical use/storage

• Share with other labs

Green Lab CertificationGreen Purchasing

• Energy Star

• Coordinate ordering to minimize packaging

• Order from “green vendors”

Green Lab CertificationRecycling and Waste Reduction

• Recycle plastics, glass, metals, paper and cardboard

• Recycle Electronics

• Recycle Styrofoam

• Electronic journals

Green Lab CertificationField Work

Leave no trace – recover flagging, equipment, batteries, etc.

Green Lab CertificationMeeting and Conference Travel

• Buy carbon offsets for travel or meetings

• Skype

Current Project - Stirling Ultralow Freezer

Current Project - Stirling Ultralow Freezer

• The Stirling freezer uses 50% of the electricity

of the control freezer - savings $344 per year• The Stirling freezer has potential to reduce the

cooling requirements of the building – savings $199 per year

• $3000 cost premium• Payback 5.5 Years

Current Project - Stirling Ultralow Freezer

Lifetime Cost = purchase price + maintenance and operating costs over the life of the product.

No compressor repair – savings $3500

Payback could be significantly shorter.
