FIRST PLACE | 2020 ASHRAE TECHNOLOGY AWARD CASE STUDIES

The Tennessee State Museum is the new facility housing
the State of Tennessee's historical collections and artifacts, located on Nashville's Bicentennial Mall complex.
Opened to the public in October of 2018, the museum is
137,400 ft2 (12 765 m2), with over 60% of the usable area
devoted to critical collections and artifact exhibits and
support. The museum is comprised of galleries, traveling loan galleries, a digital learning studio, a central
event lobby, exhibit support, offices, and back-of-house
rooms (Figure 1).
The Tennessee State Museum's primary goals were as follows:
* Meet critical temperature and
humidity design requirements for
artifacts and changing collections
* Meet the State of Tennessee's
high-performance building design
standards
* Achieve long-term operational
savings with easily maintainable
museum systems.
The design team met and exceeded
the owner's goals. Through integrated project solutions, the design
team delivered a cost-effective project, which met the critical needs of
the museum staff, while following
the State of Tennessee's high-performance design standards. Leadingtechnology air-handling systems,
with thoughtful distribution, were
coupled with proven and highly
efficient modular cooling and heating, and a heat recovery chiller was
instrumental in meeting those goals.

is labeled and described in more
detail as follows:
A. Distributed air-handling
units-Eleven custom air-handling
units, ranging from 4,000 cfm to
37,000 cfm (17 462 L/s) were located
around the building in locations
to protect galleries and collections
from potential issues. Eight of the
eleven units serve critical spaces
with tight temperature and humidity requirements, where constant
volume operation of 6-8 ach is
required during occupied periods.
Air-handling units include three
layers of filtration (pre-filters, gasphase filtration, and ULPA final
filters), insulated steam humidification dispersion tubes, pressureindependent chilled-water valves,
