UBER MB 1 & 2 – LEED PLATINUM / WELL GOLD MI SS ION BAY HEADQUARTERS

San Franc i sco , CA

AlfaTech is currently involved in Uber’s innovative new San Francisco headquarters which is a new 420,000 square-foot, ground up office building in the Mission Bay district. We 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. We 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.

• High-performance LED lighting with an occupancy driven network-based lighting control • Fuel cells redundantly powering building network operations • Solar domestic hot water system • PV-ready electrical system • Integrated building management system, including Smart Building Technology

• Significant reduction of building energy by means of combined hydronic chill beam and underfloor air system (UFAD) • Aggressive rainwater capture and retention. • Graywater reuse • Natural ventilation for main atrium social areas, creating a pleasant, open experience for employees and visitors. • Maximize use of day lighting to optimize workspace quality.
