The Design Engineer is usually involved in the front end design, typically taking the leadership role in the Schematic Design and Design Development, and then a monitoring role through the CD and CA phases.
Other Consultant refers to other organizations which provided significant consultation services for a building project (e.g. wind consultants, environmental consultants, fire and life safety consultants, etc).
These are firms that consult on the design of a building's façade. May often be referred to as "Cladding," "Envelope," "Exterior Wall," or "Curtain Wall" Consultant, however, for consistency CTBUH uses the term "Façade Consultant" exclusively.
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

T1 Tower was conceived as a giant glass plate, folded to the south along its vertical axis and cut by a gradual arc on its north face. This dynamic shape, whose appearance changes depending on the viewer’s vantage point, assures its insertion within the complex urban context and provides a new landmark for the La Défense skyline. The tower’s horseshoe-shaped geometry provides for great panoramic platforms at each level. Its design incorporates high quality working conditions, functional efficiency, and flexible office configurations.
The tower is oriented north–south with its giant curved glass plate tracking the sun’s path through the sky. A silk-screened shading pattern on the tower’s curtain wall glazing enhances the towers thermal performance. The high level of insulation and reduced exposure of the façades reduces heat loss in the winter. Great attention was given to the building’s relationship with the environment. The architectural and technical systems provide for the comfort of the tower populace, and assure high health and safety performance. The tower is fitted with climate-controlled heating and lighting systems.
