FEATURED SAN FRANCISCO PROJECT

Graham & Jillian McLeod

Uber Mission Bay 1 & 2 San Francisco, CA

Size: 420,000 SF

AlfaTech recently completed Uber’s innovative new San Francisco headquarters which is a ground up office building in the Mission Bay district. AlfaTech provided design/bid/build style Mechanical, Electrical, and Plumbing (MEP) engineering, lighting design, and Technology (low voltage, security, audio/visual) services, throughout the entire project. AlfaTech is part of the construction administration effort and served as the engineer-of-record for mechanical and electrical installations. AlfaTech assisted the architectural design team with optimizing performance by assessing various utility, façade and wind studies. Life-cycle cost analysis, energy benchmarking, and computational fluid dynamics were critical tools to inform the design effort. The project is designed as an innovative, ultra-high-performance building that focuses on an occupant-centric workplace and includes an elaborate IT infrastructure, a façade that responds to programmatic needs, an under-floor air distribution system, a two-building atria system incorporating natural ventilation, and a central treatment system for collecting graywater and rainwater. The interactions between the occupants, the buildings, and the ambient, were at the heart of the architectural and engineering systems; targeting lower environmental metrics of 1,100,000 kWh in reduced energy use and 2,100,000 gallons in reduced water use. The atrium façade is a complex array of vision glass combined with operable windows and skylights held together by an intricate window wall system. The design intent is to provide transparency, natural ventilation and connection with outdoors. Operable windows were strategically located on each façade to provide natural ventilation when outdoor conditions are favorable. Weather stations on each building predict shifting wind patterns, wind pressures and temperatures and control the position of the windows to prevent damage to the façade and indoors. The entire power and controls wiring infrastructure was delicately hidden inside the mullions, as well as the drip irrigation system feeding the planters. The result is a beautifully designed and skillfully constructed façade providing the occupants with a wonderful space to gather and collaborate.
