Within the Salesforce Transit Center, which is the central hub of San Francisco, space is open, and light filled. Tall, structurally expressive skylights “Light Columns” brings sunshine deep into the building, creating a vibrant and inviting atmosphere. The focal point of STC, and the solution to achieve it, is LITEFLAM XT120 system; a walkable fire-rated skylight specifically developed for this project.
This unitized multi-panel fire-rated glass floor system realized the Architects vision of “light columns” which flood the Grand Hall with natural light. The largest Light Column forms the central element of the 36- meter tall (118- feet tall) Grand Hall, STC’s primary public space. Reaching from the park, down through the bus deck and Grand Hall, and all the way to the train platforms two stories below grade, this dramatic structure will provide light and long views to all areas of the Transit Center.
The specifications put forth by Pelli Clarke Pelli was the most demanding for a fire-rated glass floor/ skylight to date. Some of these include: 2 hrs fire rating, blast-resistant, seismic rating, live loading for foot traffic and waterproofing. It is the perfect expression of form and function.
