Metrics That Matter: Energy Efficiency in Laboratories

1. Metrics That Matter:Energy Efficiency in Laboratories Pam Greenley MIT EHS Associate Director greenley@mit.edu Steve Lanou MIT Deputy Director, Sustainability slanou@mit.edu

2. Intro

3. What Does Campus Sustainability Mean at MIT? Minimizing our campus energy and environmental footprint Building and supporting a local community Leading by example – sharing results Creating a learning laboratory – “mens et manus” Enabling and facilitating community aspirations

5. Translating Sustainability Into Action Power Production Conservation & Efficiency Sustainable Design Transportation & Operations Community Engagement Educational Opportunities Waste, Recycling & Composting

6. Current Metrics of “Sustainability”

7. Current Metrics of “Sustainability”

8. Energy Efficiency Success to Date Utilities purchased for FY12 $30M = < 3% of overall operating budget Cumulative Energy Savings

9. You can’t build your way out

10. Building 18: Collaborative Experimentation

11. Reduce Fume Hood Face Velocity Building-Wide • Worked collaboratively with EHS experts to determine appropriate optimization of safety and efficiency • Collaborated with leading faculty and researchers • Tested range of face velocity rates • Consensus rate of 80 feet per minute rate identified • Recalibrated 130 hoods in Building 18 to 80 fpm from 100 • Building control software modified • Air control valves reset • Air diffusers adjusted and relocated • Certified all hoods to ASHRE 110 standard • Results • Cost: $306,000 • Estimated Annual Savings: $162,000 • Simple Payback: 2 years • Performance monitored via Cimetrics system • Reduced rate now used in new facilities

13. Four Types of Projects for EHS Involvement • New Lab Buildings – Koch Institute • Single Principle Investigator lab renovation • Existing lab building energy conservation project • Supervising undergraduate research projects

14. Koch Institute for Integrative Cancer Research • Research Mission – Integrating biological investigation with engineering technology • 40 laboratories, 500 researchers • 180,000 sq ft of research and work space • 100 hoods, x bsc’s • 30% less HVAC energy use/ LEED Gold

15. Koch Institute Design Process • EHS brought in early • Facilities and EHS agreed to approaches • Type of hoods • Type of controls • Face Velocity • Duct Velocity • Heat Recovery • Challenged rules of thumb Using existing labs to confirm plug load

16. Final Lab Ventilation Design • EHS related considerations • VAV and CV hoods • 80 fpm, 18-inch sash height (60 in future) • Occupied 6 ACH or hood min • Unoccupied 4 ACH or hood min • Heat pipe for heat recovery • Picture or this?Other Important EC • ACH driven by heat load(5 plug ,1 lighting w/ft2) • Low duct velocity , 1200 vs 2000 feet per minute • Segregation of freezers • Cascading air from offices to labs • Chilled beams in offices

17. Koch Institute Lessons Learned To Date • Researchers questioned containment of quiet hoods • “Offices” in Labs • Occupancy sensors need fine tuning

18. Continuation of Program • [Green Team • Ongoing Education of researchers]

22. The Perfect Lab Energy Conservation Project – Existing Building • Common Goals • Increase energy and material use efficiency • Safer Labs (appropriate ventilaiton) • More engaged and educated lab occupants • Increased Comfort and productivity • Lab level energy use info provided real time • They understand how their lab ventilation system works.
