Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

Structural Material
Steel
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.

Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

Energy Label

5 Star Green Star Design Rating from the New Zealand Green Building Council

Height
Architectural
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

96.3 m / 316 ft

To Tip
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).
96.3 m / 316 ft
Occupied
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
72.3 m / 237 ft
Floors Above Ground
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

21

Floors Below Ground
The number of floors below ground should include all major floors located below the ground floor level.

# of Parking Spaces
Number of Parking Spaces refers to the total number of car parking spaces contained within a particular building.

170

# of Elevators
Number of Elevators refers to the total number of elevator cars (not shafts) contained within a particular building (including public, private and freight elevators).

7

Tower GFA
Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

About Deloitte Center

This building is a site specific response to the existing Auckland central business district context, and to the history of this sacred Maori site which was once a fertile river valley that flowed into the Waitemata Harbor. The building embraces a material strategy to acknowledge the former location of the land/sea edge, and to create an “anchor” to recall the former location of the harbor.

The building has been designed to respond to the variable scale of context of the whole city block. This is achieved by the podium being scaled and articulated to both the width of the adjacent streets and the height of the buildings on the opposite side of the street. Many are identified as historic buildings of their period and the boundary alignment of such a collection of buildings becomes a significant urban design and streetscape determinant. Thus the podium was developed to ensure the special character of this heritage precinct in downtown Auckland is respected and revitalized. The overall massing of the building is comprised of vertical sliding gestures that emphasize the building height, reference the most important intersection in the city and playfully recall the
previous alignment of Auckland’s Harbor. In addition to these broad moves, a finer scale is achieved by a varied use of façade materials and articulation that respond to orientation. A triple skin on the west elevation with automatic louvers regulates airflow through the cavity and creates a highly transparent façade.

Winter gardens distributed over six levels create interconnecting voids that animate the podium spaces to deliver a high performance work place. The two tenants in this building—the Bank of New Zealand and Deloitte Ltd—have very different work styles. To most effectively accommodate these two work styles, the building shifts from a large floor plate central core building at podium level to an offset/end core in smaller floors through the tower. This shift in floor plate configuration was achieved while also avoiding any structural transfers.

The Deloitte Centre is a pilot project for the introduction of the New Zealand Green Building Council rating system. This building is the most environmentally sustainable commercial office building in New Zealand and pioneered the development of the system.
