High-Performance Fume Hoods: The Answer to Your Needs
or a Silver Bullet?
Diane Kase and Wade
Conlan, X-nth (formerly Earl Walls Associates)
Fume hood manufacturers market their high-performance
hoods as being able to provide up to 60 percent energy consumption
savings over standard fume hoods. Many facilities use this type
of hood believing they will reap these "potential savings."
Are these facilities really getting their return? Should they be
using high-performance hoods or standard hoods? Since there are
multiple factors that influence the fume hood selection for a specific
project, each should be evaluated for its particular application.
This poster will explore those factors in order to help facilities
determine if a high-performance hood truly is a value-added item
or just an expensive piece of furniture. Our analysis touches on
the type of science, fume hood density, module width, laboratory
operation schedule, first costs versus operational costs, and the
fume hood exhaust system design (CV or VAV). The poster will show
a brief history of fume hood trends leading up to and including
the high-performance hoods in order to fully discuss the hood selection
factors. And finally, examine case studies from our experience to
show the optimum application of high-performance hoods.
