Evaluating Alternate Fume Hood System Technologies
Using Advanced Building Simulation

Recent design improvements in laboratory fume hoods
present new opportunities to reduce the ongoing energy costs of
a research facility, as well as reduce the first cost of the HVAC
equipment. Also, depending on the number of fume hoods and the size
of the facility, it may be possible to reduce the building size
and floor-to-floor heights due to the reduced mechanical system
size. Since laboratory design often involves the use of large amounts
of outside air, the energy savings will differ based on geographic
We will present information derived from energy analysis and life-cycle
costing exercises using competing technology fume hoods that will
demonstrate their impact on energy usage and HVAC equipment capacity,
as well as offer commentary on the potential reduction in building
size. We will also present the corresponding reductions in ozone-depleting
and global warming gasses. All of the analysis and findings will
be based on different geographic regions (Northeast, Southeast,
Midwest, Northwest, and Southwest) in the United States. The information
will be benchmarked against the ASHRAE 90.1 standard and LEED.
We feel this presentation will:
- Reinforce the need to look at laboratory design from a whole-building
approach. By performing detailed energy analysis and life-cycle
costing early in the design process, the design team can determine
the overall size requirements of the mechanical and electrical
systems more precisely, not by just using industry standards and
rules of thumb. This will potentially result in a smaller building
footprint that will require less building materials and reduce
the overall cost of the building.
- Demonstrate the power of using life-cycle cost decision-making.
Having detailed analysis on the potential energy savings and operational
cost reductions, as well as first cost information, will help
the building owners and end-users understand how their decisions
will affect the long-term costs of the building and the impacts
on the environment.
- Showcase available sustainable energy technology and systems
that can help reduce the overall energy use of the facility.

sales manager, and designer for architectural and laboratory products.
After leaving the University of Pittsburgh, Karl was employed as
a Facilities Engineering Technician for PPG Fiber Glass Research
Division. Working closely with the researchers and the architect
during the design and construction gave Karl his entrée into
the world of laboratory consulting.
As the Director of Business Development at Earl Walls Associates
(EWA), Mr. Aveard has responsibility for marketing the laboratory
design and engineering services of the firm to new and existing
clients. As a consequence of his advanced knowledge of laboratory
casework, fume hoods, and other scientific products, he is a valuable
resource for the firm's laboratory planners and designers.
Mr. Aveard has been an active member of the American Society of
Heating, Refrigerating and Air Conditioning Engineers (ASHRAE),
and is currently serving on the committee for the rewriting of ASHRAE
110-1995 (SPC-110). He is also a member of the Construction Specifications
Institute, the U.S. Green Building Council, the Society for College
