Height

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).

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."

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).

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.

About Strata
Strata SE1 constitutes a key element in the Elephant & Castle Regeneration Masterplan. This 408-apartment development has a modest footprint which creates additional areas of public realm at ground level. The scheme also includes an adjacent five-story pavilion building that will comprise residential and retail facilities. Strata will be connected to the planned Elephant & Castle MUSCo (Multi-Utility Services Company), a community combined heating and power scheme which uses renewable resources.
The tower has in many ways been shaped by both short and long-distance views of its form; hence the articulation and grain of its distinctive cladding are designed to both make their mark on the London skyline as well as creating a strong sense of human scale that engages the public when viewed close-up.
The first building in the world with cladding-enclosed wind turbines, it sets a new benchmark in terms of environmental strategy. The use of integrated wind turbines is a visually exciting means of generating electricity for a building of this height and location. The form and orientation of the building enables the best use of the dominant prevailing south–south west wind direction. The three five-bladed, 9m (30ft) diameter wind turbines are rated at 19kW each and are anticipated to produce 50Mwh of electricity per year, approximately 8% of the building’s estimated total energy consumption. To put this figure into context, it is enough energy to meet the total annual demand from 30 two-bedroom apartments (based on current 2006 Building Regulations). The electricity generated by the turbines will be used to supplement the landlords’ supply for the common areas of the building. The actual energy output of the wind turbines will be published after two years of comprehensive wind data analysis.
Each layer of the façade has been tuned to vary its performance where appropriate. Glass, the most precious and vulnerable layer, is located on the inside, with a solid aluminum panel forming the outermost layer and an intermediate zone that contains the ventilation zones and opening panels. The solid operable vents on the building’s façade allow for natural ventilation.

Strata Chosen as Featured Building
From the outset, sustainability has been key to the building's evolution. This holistic approach to sustainable high-rise design will prove to be very useful for the future of tall.
