The award-winning Environmental Science Building B12N at Skyline College in San Bruno, California offers one of the most spectacular, expansive views of California’s Pacific Coast with its stunning, 22′ jumbo glass façade. Designed for complete transparency and clean lines, this stunning façade was engineered to accommodate the seismic loads unique to coastal California, while ensuring interrupted views of the vast, blue Pacific Ocean. Using Sentech’s VetraSpan clear span façade system and no support structure, the glass spans freely between the upper and lower connections, using 22-foot tall insulated glass panels that are seismically isolated at the head to accommodate inter-story drift. This use of insulated glass units required unique perimeter connections that provide tight control of the glass deformation under wind loads. The key challenge stemmed from the need to manufacture the glass to extremely tight bow tolerances, ensuring alignment between adjacent clear span façade panels.
The first building at Skyline College with a view of the Pacific Ocean, the B12 Environmental Science Building and its award-winning jumbo glass façade, allows students, faculty and visitors alike to look out onto the horizon and educate for a shared future.
