TERRELL’s role: Façade and Structural Engineering, from Concept to Detailed Design & Site Supervision.
Construction of an office tower for Aviva France. 160 m tall and 35 stories high, the building connects the raised esplanade – the “dalle” that continues the axis of the Champs-Elysées through the district – and the urban fabric of the city of Courbevoie to the north. The tower is built to the highest environmental standards, significantly exceeding French regulations for environmentally responsible development. The building’s triple-glazed curtain wall incorporates sunshades that respond to the solar orientation of each façade, and innovative grilles that provide natural ventilation to reduce dependence on air conditioning. Additional sustainable design strategies include solar water heating, a heat recovery system, high-performance lighting, and rainwater harvesting. Two of the four sides of the building are inclined so as to optimise the use of natural daylight. The project includes a landscaped pedestrian street lined with cafés that leads to an 18-meter-high, skylit atrium, and rooftop conference and dining facilities surrounded by a garden with dramatic views of Paris.
