The building has been ingeniously engineered with sustainability at the forefront of the design. Almost 5km (3 miles) of pipe runs underneath the car park to provide the centre with ground source heat, and a further 1km (0.6 miles) of pipes, as wide as a meter in places, are also buried underground, drawing in air to cool the centre.
Water is collected from the green roof in an underground tank which is used for the toilets within the centre.
