Hypergreen

The Hypergreen project saw the light of day thanks to architect Jacques Ferrier. This 246m ecological tower complies with "sustainable building" criteria:

• environmentally friendly materials,
• upgradable construction techniques,
• everyday respect for the environment.

The tower's structural elements (slabs, walls and columns) are created in Agilia®. This self-placing, self-leveling concrete reduces effort and noise during construction and is aesthetically superior to traditional concrete.

The "outer skin", a mesh that guarantees the building's stability, is made of Ductal®, Lafarge's ultra-high-performance concrete. This reduces the raw materials needed, as well as the building's total weight

Hypergreen uses renewable sources to meet its occupants' energy needs.

• Wind turbines at the top generate electricity.
• 3,000m² of photovoltaic cells turn sunlight into electricity.
• The mesh reduces heating and cooling needs by regulating ventilation.
• Rainwater is collected for use in washrooms and gardens.

Hypergreen offers over 94,000m² of usable floor space, with room for shops, offices, apartments, green spaces, leisure areas and parking facilities.
