The Heron Tower

Heron Tower synthesises urban concerns with innovative technology and environmental responsibility. Set within the City cluster on a prominent site at the junction of Bishopsgate & Camomile Street, the building will provide the highly flexible work space that is demanded by the latest generation of City occupiers. This is a project of KPF Architecture.

Responding to both the technical and social demands of the modern workplace, the building is organised around a series of office “villages”. At the heart of each is a triple height atrium.

The building’s east and west facades also adopt a similar layering strategy. This system will reduce heat gain by about 45% over a standard glazing solution. The atria within the building face north; this enables a maximum amount of daylight penetration into the workspace, again without solar gain. The excellent daylight penetration reduces the energy expended on artificial lighting.

The building’s lifts are innovative, servicing the relatively large number of small floors in an efficient manner. The proposal incorporates “double deck” panoramic high speed lifts, with bespoke hall–call destination control software. This solution occupies 40% less area than a conventional elevator system.

The proposal has sought to minimise the size of mechanical plant at roof level by the use of an “ice storage” system. Ice is made at night and melted in peak load time to release cooling energy.
