Strategy & Services: The joint venture group between Golub & Company and The John Buck Company is constructing a new commercial office building with ground-floor retail adjacent to the Transbay Terminal in the heart of downtown San Francisco. stok was brought on to help guide the project through sustainable design aspects, with LEED Gold certification as the end goal. Leading numerous evaluations, stok identified key areas for sustainable impact in the design and operation of the building. As a Core & Shell project, stok also helped the client navigate nuanced LEED certification credits through tenant guidelines to ensure the tenant’s build out of the space would meet the high sustainability standards outlined by stok and the project team.
Design Details: Keeping sustainability at front of mind during design decisions, the 43-story development features flexible and efficient office space that optimizes the occupant experience. The tower’s most prominent differentiator is its abundant outdoor space. The highly glazed façade and 14 sky decks (a terrace every 4-6 floors) provide tenants with sights of the San Francisco Bay from 70% of the floors, with plentiful work areas with natural light, ventilation, and views, contributing both to exceptional indoor environmental quality and a healthier workspace. Beyond the aesthetics and function of the terraces — which are complimented by a large open park area surrounding the tower, totaling over 50,000 sf of outdoor space — stok helped the premium office tower target LEED Gold certification by focusing its sustainability efforts in several areas. The building incorporates native and adaptive landscaping throughout, including on the terraces scattered across the building for a more efficient design that further treats the rainwater collected through a harvesting system. The project also specified a highly efficient HVAC system with underfloor air distribution (UFAD) that both reduces energy and allows for maximum floor-to-floor heights — the most energy efficient strategy of the entire design.

Outcome: Focused on sustainability and occupant health and wellbeing, the Class A+ office space generated buzz around a number of high profile tenants wanting to expand beyond their Silicon Valley offices for enhanced talent recruitment and retention. In a move for a massive addition to its rapidly growing San Francisco presence, Facebook recently signed the lease at Park Tower, with plans to occupy the full building upon completion. With 755,900 sf of office space, the lease makes the tech giant the third largest tech tenant in the city. Given the tenant guidelines and highly efficient base building, the full build out of Park Tower will likely see further innovation in resource efficient strategies combined with human-centered design for a healthier occupant experience and robust financial payback.
