<strong>Lab</strong>RATS<br />
A program developed by and for researchers<br />
and support staff to directly address the unique<br />
challenges and opportunities to reducing the<br />
environmental impact of laboratories.

The Challenges<br />
• Myth: Research can‟t be effective and safe<br />
without its current consumption level<br />
60,000 gallons of water saved in<br />
one year by making a minor<br />
modification on the set-up of<br />
this still.

Energy – HVAC Opportunities<br />
•Close VAV sashes<br />
- monitor and report performance<br />
•(Safely) „tweak‟ parameters<br />
- flow rates; temperature and humidity control bands<br />
•Switch off/turn down HVAC “out of hours”<br />
- zone proximity sensing (ZPS)<br />
•Upgrade equipment<br />
- variable speed drive motors
Harvard – Sash Closing
Fume Hood Sticker<br />
• Safety approved<br />
• “Red Zone Compliant”<br />
<strong>Lab</strong>s<br />
• Record sash positions<br />
during inspection<br />
• Diversity to 10-20%?
Nottingham Case Study<br />
380 fume cupboards<br />
linked to BMS -<br />
calculate average sash<br />

Monthly reports sent to<br />
lab users, with estimate<br />
of energy savings<br />

•Procure Energy Efficient Freezers<br />
•Energy Star label for <strong>Lab</strong> Grade freezers<br />
Data supplied by University of Newcastle
Newcastle Case Study<br />
•£180,000 of central funding to replace old<br />
lab fridges/freezers<br />
•36 -80 freezers replaced saved 137,000 kWh,<br />
or 70 tCO 2<br />
•Also reduced space, increased reliability,<br />
more £ for research
Case Study<br />
– Blizard Institute<br />
•Improved sample tracking & management<br />
•Handheld barcode scanners and labels<br />
•Reduced no. frozen samples in dewars by 50%<br />
through better inventory management & disposal<br />
•Standardised containers - more efficient use<br />
• of space<br />
•Location tracking - sample retrieval quicker and<br />
easier
Sample Storage - Stanford<br />
•350 labs, 2,000 -80 freezers<br />
•Pilot found ~9-13 million samples<br />
could be stored at room temperature<br />
•3 to 5 year payback for investment<br />
•~ $11-20 million/y cost reductions<br />
•Greater reliability<br />
•More space
