PTW designs new corporate head office building for Invest AD in Abu Dhabi
This leading edge, sustainable office tower was specifically designed as the new corporate head office building for Invest AD, a leading UAE financial company. The flagship corporate Headquarters, consists of a 22-storey tower containing a total GFA of 22,000 sq m which is spread across a flexible rectangular floor plate with a side core configuration to minimise eastern solar heat gain.
The western elevation is articulated with a series of fixed and operable glass louvres which provide both solar shading and the potentially natural (winter) ventilation to the six-storey, upper garden atrium creating a luminous roof top lantern. The south façade is dominated by the building core which features two glass lifts. The east and north facades are set back on top of a podium rising 16.2 m from the ground level. All facades except for the south facade feature a super-grid frame structure with a curtain-wall skin behind. The east and west facades’ super-grid incorporate metal louvers for added sun shade.
At ground level along the west boundary a colonnade defined by the superstructure from the tower above forms part of the main entry into the building and car park areas. The ground level on the east side of the site combines retail with building service requirements. The crown of the building is articulated according to the functional requirements of service equipment (lift core and plant room) and to proportionally enhance the building tower. The west-facing super structure forms the pinnacle of the building crown assembly rising above the highest roof level to frame the sky and best feature signage and lighting. Currently under construction with completion due mid 2012.
