![]() ![]() On the south elevation the core serves to protect the building from excessive heat gain and incorporates a photovoltaic array-laminated units on the vertical façade of the scenic passenger lifts and plant areas. To the east and west the highly transparent, ventilated façade creates a bio-climatic, energy-efficient enclosure with automatic integral blinds controlling the direct long angle sun. The orientation of the building informed the design of the façades. These villages are structurally expressed on the northern face by the stainless steel cross-bracing and articulated to the east and west, animating the façade. ![]() ![]() In addition the design of the building’s services systems incorporates features that ensure that energy is used efficiently with heat recovery, high efficiency plant and low-energy cooling systems, bringing energy savings, cost benefits and allowing the refit of new technologies in the future. Optimizing the core of the building off-set to the south enabled the design of large, open, flexible office spaces, which form the 10 “villages.” Each of the villages is environmentally independent, with its own mechanical and electrical systems, life safety systems and controls so that each can be tuned to exactly the comfort patterns and values of its occupants. An extension to the public realm is also incorporated at roof-level with dining terraces associated with the public restaurant and bar providing views across London. Similarly an arcade along Bishopsgate has been created to provide a generous footpath to the busy street and address the Grade II listed St. On a busy traffic corner, with narrow pavements, the public realm has been enhanced by opening up a pedestrian section to the north, along Houndsditch, animating the space with planting and cafés. Responding to its urban context, the redevelopment of the Heron Tower site also incorporates significant improvement to circulation and access around its base. A series of nine three-story “villages” and one six-story “village”-with a full-height atrium at the heart of each-create independent spaces and provide high levels of visual connectivity while maximizing daylight deep into the building adding human scale and a sense of community. ![]() The design of the tower provides highly flexible work-spaces which support diverse tenant needs. Within a composite building’s primary structural elements. Where known, the CTBUH database breaks out the materials used Examples include buildings which utilize: steel columns with a floor system of reinforcedĬoncrete beams a steel frame system with a concrete core concrete-encased steel columns Ĭoncrete-filled steel tubes etc. steel, concrete, timber) are used together in the main structuralĮlements.
