Undergrad Teaching Labs

Planned Sustainability Features:• Install occupancy sensors• Set-back controls on ventilation during unoccupancy• Installation of sub-meters to verify/monitor

• Occupancy in Teaching Labs is 181 full day equivalents

• Electrical cost for ventilation is ~100K$ /year• Potential Cost saving with a 50% reduction

is ~50k$/year• Demand Based Ventilation could introduce

even greater savings


Research Laboratories

Provide World Class Labs( Renovate, Accommodate more fume hoods)



The Challenge:

The Research Mission

Conduct World Class Chemistry Research

Attract the Best and Brightest Chemistry Minds

Accommodate more fume hoods with limited building ventilation capacity



The Challenge:

• use of reduced velocity fume hoods• use of cascading air supply systems• conserve: “Just Shut It” Awareness• right size the plug distribution

Labs 21 Lessons Learned:



Use of reduced velocity fume hoods

saves ~250 CFM air requirement/hood

@ $6.00/CFM save $1500/hood20 hood save $30,000/yr20 Y life cycle save $600,000

Labs 21 Lessons Learned




Use of cascading air supply systems

Redirect office/lunchroom air exhaust

to lab air supply
