The Building 18 Energy Problem

• Home of Chemistry department
• 2 energy consumer / sq ft on campus

Where does the energy go?
CO2 emissions
Cost
1.8 million
8500 metric tons
Emissions equal to over 300 SUVs driving 60 mph

Fume Hood Interventions

• Phased information campaign
• Collaboration between EPO, LFEE, EHS, Chemistry,
  students, faculty and staff
• First EHS lab rep. discussion Nov. 2006
• Monitoring of avg. sash position ever since
• Information feedback starting July 2007

Estimated hood air flow

• Estimated annual savings
• 32,000
• 117 tons CO2
• Heat for 15 homes

Impacts are difficult to assess
Total air flow through building? Behavior change
vs. re-commissioning? What are the limits?
