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.

Project Manager
The CTBUH lists a project manager when a specific firm has been commissioned to oversee this aspect of a tall building’s design/construction. When the project management efforts are handled by the developer, main contract, or architect, this field will be omitted.

About 181 William Street
181 William Street is a new major corporate presence in the high ground of the west end commercial precinct of Melbourne. The entire project is designed on a holistic basis to integrate the façade with all services systems to achieve high quality environmental performance. During the course of a comprehensive design process, all services systems were integrated to ensure high quality environmental performance, flexibility and long life.
The tower façade is visually arresting in the use of colors in the vision and spandrel glass, creating a balanced geometric pattern that captures a sense of movement across the façade. The russet color pallet was selected to reflect a richer and more distinct corporate presence. The range of seven colors to the spandrel and vision glass has been distributed in an ordered manner that has been inspired by the dot painting technique of Australian indigenous art. The white columns are metal clad with the lower sections expressed in polished stone. The elevated podium is clad in zinc with expressed joints and flush glazing to match. The north and south inset façades are in clear flush glazing.
The tower is designed to achieve maximum natural light, views and workplace flexibility. The project has achieved a certification rating of Five Green Stars and 4.5 Star ABGR. These rating systems are administered by the Green Building Council of Australia and subject to rigorous audit and monitoring. These assessments cover all elements of sustainable performance, including the consideration of embodied energy, recycled construction materials, indoor air quality and VOC analysis, and ongoing environmental performance. This is equivalent to a LEED Gold rating.
