UBER | MI SS ION BAY 1 & 2 LEED PLATINUM, WELL GOLD San Francisco, CA

Type: New Site, Two High-Rise Office Buildings Size: 420,000 SF

AlfaTech is currently involved in 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 buildings' eco-friendly features consisted of: • Two passively conditioned, interconnected atria • Shaded facade with automated natural ventilation

• Chilled sails and occupant-controlled underfloor air-distribution systems • High-performance LED lighting with an occupancy driven network-based lighting control • Graywater reuse and rainwater catchment systems • Integrated building automation, controls and management platforms • Full air-side and water-side economizing • Fuel cells redundantly powering building network operations • Urban garden • Solar domestic hot water system • PV-ready electrical system
