for its signature silhouette, the Eiffel Tower is
synonymous with the city of Paris, France. When
a renovation project required two wind turbines
to be added within the landmark’s frame, project
managers were able to install them while keeping
the tower’s iconic figure intact.
And that wasn’t the only unique project
accomplishment. Stakeholders from the Société
d’Exploitation de la Tour Eiffel (SETE) and the
office of the Mayor of Paris also made it clear that
the turbines couldn’t be lifted with cranes, which
could damage the 126-year-old tower. In addition,
the project needed to accommodate the flow of
revenue-generating tourists during business hours.
This meant the team needed to find ways to do the
most intrusive work at night—without disturbing
The project, which was completed in February,
was part of a two-year, € 30 million renovation that
was also charged with adding LED lighting and solar
panels to the first floor of the tower. The turbines
were required to generate only enough energy to
power the tower’s first-floor commercial areas,
which include a restaurant, a gift shop and a histori-
cal exhibit. Although the total is less than 1 percent
of the overall energy that the tower consumes in
a year, it helps nudge Paris toward a citywide goal
to reduce greenhouse gas emissions 25 percent by
2020 and 75 percent by 2050.
The project was part of multiple green initiatives in France less than a year before Paris is
scheduled to host the 2015 United Nations Climate
Change Conference in November and December.
For instance, in March, France introduced a law
that requires plants or solar panels to be installed on
the rooftops of new buildings in commercial zones.
“Not many people are able to work on this kind
of turbine,” says Sébastien Reinier, project manager,
