TCB Torre Hadid , Milan

An iconic tower within the Milan Cityscape designed by Zaha Hadid.

The TCB Hadid Tower project in Milan will form one of the iconic towers within the City Life Development and within the Milan Cityscape.  

The Tower is approximately 170m high with approximately 40,500m2 of cladding surface area comprising of 6 different cladding types.

The project aims to create a portal to the Fiera Milano mainly characterised by the flowing and twisting form of the main tower and the crystalline double skin facade that wraps around the majority of the tower.

This 43-storey tower has two main flanks left and right of the building that are made up of a double skin facade that wraps around the building.

Arup carried out the façade engineering of this project due to become an iconic tower in the city.

A double skin façade 

The outer skin follows the twisted form of the building and thus requires cold bent glass (warm bent or hot bent glass if required in areas of extreme warp) while the inner skin follows a facetted form that best approximates the flowing outer form.

The façade is conceived as an externally ventilated double skin façade in which the thermal line is set to follow the setting out of the inner glazing line. 

The use of an externally ventilated double skin façade can reduce the heat flow that would otherwise enter the building while the inner skin is designed as a floor to floor façade system that allows continuous seals to be made from the façade system to the slab at each level and allows the detailing of the cavity finishes to be less critical to the weather and vapour performance of the façade. 

The setting out function for the tower results in a number of geometric complexities that have been addressed like the irregular shape of outer skin panels, the warping, the offset between inner and outer facade varies on plan and in elevation up the height of the building.
