Topson Downs New LEED Corporate Headquarters
Culver City, CA

Constructed in 1954, this Culver City former industrial building has been transformed into a state-of-the-art office space for Topson Downs. As part of the design team, Syska Hennessy Group was contracted to provide professional engineering services for this new sustainable space.

One key element to achieving LEED Gold certification was a 6 kW unifacial roof mounted photovoltaic (PV) system. Syska Hennessy Group, in collaboration with a third-party vendor, designed this PV grid-tied system with interconnection to Southern California Edison (SCE) serving utility company metering equipment. This size system accounts for approximately 2.5% of the total building electricity use.

Additional sustainable system elements includes energy efficient plumbing systems to support a 40% reduction in water usage and the HVAC system was designed to accommodate natural ventilation for end-user thermal comfort.
