Landmarks don't come much more iconic than the Eiffel Tower, but if you've ever visited it in person you may have found the first floor mildly underwhelming. Architectural firm Moatti-Rivière aims to change this, and add some sustainable technology to the mix, during a redevelopment of the tower's first floor that's currently underway. On turning the tower green, and as part of this process, New York's Urban Green Energy (UGE) recently installed two wind turbines that should reduce the carbon footprint of the iconic landmark. Vertical axis wind turbines to be precise – were installed in partnership with the Société d’Exploitation de la Tour Eiffel (SETE), the body responsible for maintaining the Eiffel Tower. Moatti-Rivière name-checks a shopping list of sustainable technology slated for installation on the tower – solar panels are intended for the pavilion roofs, while wind turbines, a rainwater catchment system, and LED lighting also feature.
