Practice Stretch Goals
Out-perform 20% UCI currently outperforms 2005 Title 24 Outperform 2005
ASHRAE 90.1 standards by > 20%. Recent CA Title 24 by 50%
(CA Title 24, Part 6) construction achieved 33%. Expect to
out-perform 2008 Title 24 standards
(effective 1/2010) by 20% or more.
Occupied lab air- 6 ACH 4 ACH w/centralized demand controlled 4 ACH w/CDCV

Unoccupied air- No setback 2 ACH with occupancy sensor & CDCV 2 ACH with occupancy
changes/hr. w/setback in fume hood driven lab, pilot testing sensor & CDCV
Fume hood – face 100 FPM Use low flow fume hoods. Our initial 60 FPM (using low
velocities study encouraging at 70 fpm face flow fume hoods
(occupied) velocity. Awaiting Cal/OSHA variance where applicable)
to further test.
Fume hood – face 60 FPM Use low flow fume hoods. May be 40 FPM (using low
velocities achievable in fume hood driven lab to flow fume hoods
(unoccupied) reduce to 40 FPM. where applicable)
Fume hood None Other features more cost-beneficial In fume hood-driven
auto sash closers when hood density is not high lab needs to be

new hood.
Exhaust stack ~3,000 Increasing stack height (~ 5 ft.) with Optimize stack height

Energy Star freezers Yes Exchange program in effect for older Yes
and refrigerators refrigerators. Required by policy for all
new equipment purchases.
Duct noise attenuators Few None - Reduce noise by using two None
<0.1 in. smaller fans in parallel instead of a
w.g. of single larger fan.
static loss No attenuators used due to large
associated pressure drop. Provisions
