Erected in 1910, the 10-story Denver Gas & Electric Building (also known as the Public Service Company Building) once served as a single vast advertisement for the wonders of electricity, thanks to the 13,000 lightbulbs embedded in its white terra cotta façade. The bulbs went dark for a time after World War II but were rewired in the 1990s, and the building once again lights up Denver’s central business district each night. Designed by local firm of Frank E. Edbrooke & Company, the building is an example of the early skyscraper style pioneered by Louis J. Sullivan of Chicago. The geometric patterns created by the bulbs, along with dramatic details such as the arched tenth-floor windows, ensure that the building is a striking sight by daylight as well.
In the early years of the twentieth century, Denver promoted
itself as the “City of Lights”, thanks to its newly illuminated downtown
skyline, anchored by the “best lighted building in the world”, at 910 15th
Street. Built in 1910 to house the newly
consolidated Denver Gas & Electric Company, the Gas & Electric Building
provided visual evidence of the new prominence of electrical technology in
American life and of Denver’s status as a modern city.
As one of the rapidly growing “instant cities”
of the American West, Denver provided an ideal market for utility companies seeking
to promote electric- and gas-powered appliances as a necessary element of the
modern home. An early photograph of the building shows a sign claiming The Christmas gift will please if it's an electric iron, chafing dish,
toaster, coffee percolator or artistic electric stand lamp - looking for a useful Christmas gift? - see our household electrical appliances ( http://digital.denverlibrary.org/cdm/ref/collection/p15330coll22/id/1501).

America by historian Mark H. Rose, which follows the growth of utilities in
Denver and Kansas City.
Officially the work of local architectural firm Frank E.
Edbrooke & Company, the building’s design has been attributed to Frank
Edbrooke’s nephew, Harry J. Edbrooke, who would go on to create many notable
structures in Denver after establishing his own firm in 1913. The building
exemplifies the new American “skyscraper” style created by the Chicago
architect Louis J. Sullivan in the late 1800s, when steel-frame construction
and the invention of the elevator made truly tall buildings feasible. The Gas & Electric Building echoes
Sullivan’s pioneering designs, especially in its three-part design and its use
of ornament. The lower stories form a solid base below an eight-story shaft
crowned by an overhanging cornice. The
arched tenth-floor windows seem to flow upward into the curving cornice,
providing a contrast to the simple squared-off forms of the middle stories.
What really makes the building stand out, however, are the
13,000 light bulb sockets embedded in the bright white terra cotta of the façade.
The lights trace the outlines of the building while creating geometric patterns
of their own. In the building’s early
days, it was referred to as “the best illuminated building in the world”, and
around 75,000 people – roughly a third of the city’s population at the time –
attended the initial switching-on of the lights. The ornamental lights remained
in use until World War II gave rise to mandatory blackouts. The building was renamed the
Insurance Exchange Building and the lights fell into disuse after the Public Service Company of Colorado (Denver
Gas & Electric’s successor) moved to a different location in 1962. The building was
restored and the lights re-lit in 1990. It is listed on the National Register
of Historic Places.
