1. Energy Use and Energy Awareness at the CNS Building Lia Stelljes, Physics ‘08 Beth Ellen Clark Joseph, Physics CNS Sustainability Group Office of Facilities (Data Contribution) Michael “Bodhi” Rogers, Physics Fume Hood Electricity Use Awareness Study

2. Does awareness affect electricity use?  1 week “ad campaign”  Repercussions of fume hood misuse  Hypothesis driven Awareness increases Electricity decreases Goals:  understand laboratory energy use  calculate dollars saved  calculate decrease in CO 2 emissions  decrease building consumption  global awareness and change

3. Data Collection  Study week Nov. 10 th – Nov. 17 th Based on past data Electricity use fluctuates

4. Data Collection  Study week Nov. 10 th – Nov. 17 th Based on past data Electricity use fluctuates JanMarMayJulSepNov

5. Data Collection Continued

6. Study Data BREAK

7. Statistical Analysis of Results Comparing Average Peak of Normal Weeks with Peak of Study Week Normal Weeks Study Week electricity use (kWh) Promising results!

8. Future Work  Continue Study Include more weeks in analysis Natural gas data Other areas of energy use

9. Conclusion Baseline use estimate Consumption levels change with awareness Efficiency measures implemented in CNS in 2006  Average decrease 2000 kWh/month  Dollars saved: $2400 /yr ! Decrease in CO 2 emissions: 33600 lbs/yr!
