At San Francisco Bay, the transportation network company UBER has built its company headquarters, composed of two office buildings for a total of up to 3,000 employees. The glass architecture aims to reflect UBER's open corporate culture.
Gartner has cladded the two 55 m (180 ft) and 33 m (108 ft) high buildings with highly transparent exterior and entrance façades and several skylights. The buildings are connected by two earthquake-proof steel-glass bridges, able to withstand movements of up to 762 mm (30”). A unique feature of the development is the special-purpose solution for the numerous glazed atria which are naturally ventilated via windows (size 4.3 x 3 m / 14 x 10 ft) in the exterior façade. To ventilate the semi-conditioned atrium space inside the external glazed envelope a transparent, steel-framed glazing system featuring motorized bi-fold units was designed. These 162 operable window units are computer-controlled in conjunction with operable skylights to maintain comfortable temperatures and reduce the need for mechanical ventilation. Each window consists of two sashes, each 1.5 m (5 ft) wide, connected by folding hinges, with ultra-clear low-iron laminated safety glass. They make up approx. 20 percent of the glass envelope.
Thanks to natural ventilation and a high degree of daylight utilization, the energy-efficient building envelope makes a significant contribution to the sustainability of the buildings, which are expected to meet LEED Platinum requirements.
29,700 sqm (319,700 sq ft) of façade, including unitized aluminum façade, skylights, 162 electrically operable windows, building façade, entrance façade, two bridges.
