Located at a prominent intersection of Mission and Fremont Street in the city of San Francisco, the 350 Mission Street building is a 27 story speculative office building with an offset core rising 414 feet, and consisting of approximately 492,980 gross square feet with basement parking of up to 58 vehicles. The building features a 50 foot tall lobby that also functions as a free flowing open public space. Additionally, the lobby features a unique folding glass wall system that creates an unobstructed connection to Mission and Fremont streets, while maintaining the climate with an energy efficient radiant floor heat and cooling system.
The building is clad with articulated high performance unitized curtain wall alternating angled panels that give the appearance of a weave as sunlight reflects off the surface. HVAC underfloor air delivery systems also allow for least possible energy consumption and carbon footprint. The unique system heats and cools only that portion of the space actually used by occupants — and not the space above their heads to the ceiling —thereby creating a significant efficiency over current systems that wastefully condition the entire air/building mass in any given room. The building also has a 100% outside air capability, which translates into a significant energy reduction.
