Innovative Approaches Fume Hood Conservation
2
UCI A Research University

• Approximately 27,000 students
• Energy bill is 1,000,000 per month
• 2/3 of energy used is in the labs
• Fume hoods comprise the largest portion of energy
  consumption in the lab

3
No-cost Fume Hood Conservation

• Shut the Sash Campaign
• Partnering with Laboratory TAs
• Incorporate fume hood energy practices into
  syllabus
• Present to class laboratory lectures

4
Low-Cost Fume Hood Conservation

• Carbon Footprint Stickering
• Stickers from UCI Administration
• Partner with EHS
• Paid For-credit interns
• Stickers promote energy
• conservation through closing fume
• hoods

5
Low-Cost Fume Hood Conservation

• Fume Hood Competition
• Energy saving competition between labs on campus
• Baseline measurements of sash opening
• Usually 3 week competition
• Energy savings calculated with Lawrence Berkeley
  National Laboratory Model
• Prizes awarded to winning labs

Advanced Retrofits

• VAV Fume Hoods
• Variable Air Volume
• Save energy when closed
• CAV Fume Hoods
• Constant Air Volume
• Same amount of energy when open or closed
• Can be upgraded
• Phoenix Sensor
• Senses movement
• Makes a CAV hood work like a VAV hood
• Saves energy when not in use
• Complex upgrade that requires Facilities
  Management

Biomed Fume Hood Competition

• 3 buildings in the College of Medicine
• Sprague
• Gillespie
• Hewitt
• Some hoods were VAV, some were CAV, and others
  were CAV upgradable
• Calculate energy saved as well as energy that
  could be saved if hoods are upgraded with a
  Phoenix sensor
• Present Data to Campus Energy Manager to advocate
  for the upgrade
