The Hypergreen project saw the light of day thanks to architect Jacques Ferrier. This 246-meter ecological tower complies with "sustainable building" criteria: environmentally-friendly materials, upgradeable construction techniques and everyday respect for the environment.
The structural elements of the Hypergreen - the slabs, walls and columns - are conceived in Agilia®. This self-placing, self-leveling concrete reduces physical effort and noise pollution during the construction phase. It also offers superior esthetic qualities compared to traditional concrete.
The "outer skin", a mesh which guarantees the stability of the building, is made of Ductal®, Lafarge's ultra-high performance concrete. This reduces the amount of raw materials needed for the construction and also reduces the total weight of the building.
A tower that meets its own energy needs
Hypergreen uses renewable sources to meet the energy needs of its occupants. For this:
- wind turbines at the top of the tower generate some of the electricity,
- 3,000 m² of photovoltaic cells transform sunlight into electricity,
- the mesh structure reduces heating and cooling requirements by regulating the ventilation of the tower,
- rainwater is collected for use in washrooms and gardens.
A multipurpose tower
Hypergreen offers over 94,000 m² of usable floor space. Encompassing all facets of urban life, it has room for shops, offices, apartments, green spaces, leisure areas and parking facilities.
