Fume Hood Electricity Use

Awareness Study

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 CO2 emissions decrease building consumption global awareness and change

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 CO2 emissions: 33600 lbs/yr!
