Wilma Rudolph Lab presented a unique challenge to the design team. The original facility
did not contain the infrastructure necessary to
support a large testing lab environment. Lab
buildings are traditionally high users of energy
resources, resulting from the following lab
• High and varying internal appliance loads.
• High outside air ventilation requirements to
meet the makeup air needs of multiple fume
hoods and general dissipation of volatile
gases and chemicals used in the testing.
• In order to satisfy the peak cooling and
ventilation requirements of a lab, a 100%
outdoor air system is frequently employed,
which requires all of the outdoor air to be
cooled and dehumidified continuously,
regardless of the actual internal cooling
load. This system is both expensive in terms
of capital cost as well as operating cost.
The HVAC system employed in the Wilma
Rudolph design targeted safety as the number one
priority. This need was closely followed by flexibility, comfort, energy efficiency, reliability and
maintainability as equally high priority objectives.
Venturi wedges were used throughout the
new lab areas. For every 100 cfm of primary
air supplied, about 230 cfm of room air is
induced across the coils. This arrangement
permits only the minimum amount of out-
door air needed for hood exhaust and general
lab dilution to be cooled and dehumidified.
The remaining cooling requirements are supplied by recirculating room air over the secondary coils. This configuration reduces peak
cooling requirements as much as 60% over
100% outdoor air systems.
A single central air handling unit (AHU)
preconditioned all the primary air supplied
to the induction terminals. This unit was
equipped with a total energy heat wheel that
extracted up to 70% of the sensible and latent
cooling energy from the general exhaust air
stream to temper all of the incoming ventila-
tion air. A separate exhaust system was pro-
vided for the fume hoods.
The owner saved both first cost by reducing
the size of the air handling system, the duct
distribution system and the central air cooled
chillers and in long-term utility costs.
The Wilma Rudolph Sports Testing Lab
offers an environment that has been purposely designed to appeal to both employees and
visitors. In addition to clean, uncluttered lines
and soft, recessed lighting, the space features
artwork selected by Dr. Black, cushioned
flooring for employee comfort while working
and visual access to the outdoors. Windows
were added to allow visual contact with the
outdoors and allow borrowed light into the
lab. The design includes areas for employees
on the first and third floors. In addition, the
building will accommodate up to 12,000 sf
of future lab space in what is now an existing
recording studio and warehouse.
The new lab allows Aegis Sciences Corp. to
operate more efficiently while continuing to
provide the highest-quality forensic services.
The new facility will allow the company to keep
up with the increasing demand for its services.

The building currently has 10,000-sf of lab space with 12,000 sf for future lab expansion.
; Download the new BIM specification. A nationwide group of building information
modeling users, known as the BIMForum, released the first-of-its kind standard establishing definitions for how complete building information models need to be for different stages of the design and construction process. The new standard, known as the
level of development specifications (LOD), was developed under an agreement with the
American Institute of Architects. The standard allows everyone involved with construction projects to clearly articulate how detailed model elements for the different building
systems are or need to be throughout the design and construction process.
“We want everyone to have the same understanding about how much information
should go into each element of a building model, and for what uses those models are
suitable,” said Dmitri Alferieff, the director of the BIMForum. “This specification will
eliminate much of the confusion that comes with having different expectations for
what should be in the models.”
Alferieff noted that the new development specifications allow model authors to
define what their models can be relied on for and allow other users to understand the
value, and limitations, of models they receive. With the specification is finalized, the
BIMForum is making it open to the entire construction, architectural and design com-
munity and encouraging them to use it as a reference standard in BIM agreements
and execution plans. For more information and to download the specification, go to
