Function
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
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 171 Collins Street
Developed directly out of the richness of its inner city location, 171 Collins Street is the Australian province of Victoria’s first Premium Grade 6-star Green Star office building in more than 20 years. The crystalline tower provides an iconic focal point to Melbourne’s city skyline, featuring an impressive nine-story internal glass atrium, premium finishes and facilities, efficient side core floors, a woven crystalline facade and the latest in technology and environmental design.
Its design has four main components: the Mayfair Building, the Flinders Lane podium, the atrium and office tower; together, these form a unified whole. The Collins streetscape is maintained by setting the tower form back 32 meters from the street, while the Flinders Lane facades emulate the textures and scaling devices of the surrounding brick warehouse buildings. The new 171 Collins Street complex lends an elegant but not overpowering backdrop to the historic Mayfair Building, whose façade continues to enclose the Collins Street entrance to the project.
