Who Knew? Fire Station #2 Tower is a “Sun-Tracker”
Decatur Metro | December 27, 2010
I was aware that the glass tower atop Fire Station #2 in Oakhurst had solar panels on it, but I certainly didn’t know this fun-fact.
From the Fire Station #2 Fact Sheet…
The Fire Station No. 2 Tower
A society that values sustainability will have a strong sense of its dependence on the planet Earth
The glass tower at Fire Station No. 2 is a ‘sun-tracker’. The blue color band and the red ‘2’ that can be seen moving across the glass of the tower are both created by the sun passing through colored glass mounted on the tower.
The blue band is the tower’s ‘gnomon’. A gnomon is traditionally the raised triangle on a sun dial that casts a shadow to tell the time and day. The red ‘2’, of course, represents the name of the Fire Station. The sun to the south of the tower strikes these stained glass surfaces and projects their color onto the face of the white glass. Each hour of the day and each day of the year the blue band and color red glass will demonstrate the height and angle of the most important star.
Cool!
