Figure 2. Difference between Internal Cabinet Temperature and Outside Air Temperature
artist wrap (along with the other treatments) caused an increase in
internal temperature. Figure 2 represents the difference in recorded
temperatures inside the cabinet, and the outside air temperature
with various exterior surface treatments.
Over the test period, the MEAN temperature difference for the
artist wrap was calculated to be -5.4°F (-3.0°C). Therefore, the inside
temperature was found to be cooler with application of the artist
wrap for this case study. All temperature readings were collected at
various times of day, and with/without the thermostat cooling fan
operational. An influence factor to the study was the activation of
the cooling fan. Data showed that the thermostat controlled cooling
fan did reduce the internal temperature for all exterior surface
treatments. The range of the mean for all surface treatments is
depicted in Figure 2.
The traffic signal cabinet can be used successfully to display public
art. The established City ordinance has proven to be a successful
platform to vote on the artwork, and to subsequently display the
art. Property owners, business owners, residents, and guests all
have expressed appreciation for the public art to city officials
and the Great Falls BID. The City's public art projects directly
correlate to the BID's continued efforts in the areas of beautification; working to make the downtown a clean, safe, and vibrant
place to live, work, and play. The incorporation of color and the

variety of the public art projects have been a welcome addition to
the City's downtown urban core.
Based on the case study temperature findings, cabinet
components will not be impacted by introducing public art displays
on the exterior surface of a traffic signal cabinet. From review of the
annual City maintenance records, the artist wrapped cabinets have
not increased cabinet maintenance or replacement of components
as compared to the other City intersections since the adoption of
the TSB Art project. Nevertheless, the thermostat cooling fan and
heater are integral cabinet components and they should be checked
periodically for functionality. itej
