Achieved Net-Zero Energy with 40% Faster Occupancy Than Market Average

Challenge & Innovation

Building a 32-story tower on a seismically active landfill site required groundbreaking engineering. We installed 72 friction pendulum base isolators – the tallest application in California – allowing the structure to sway 36" safely during quakes. To meet affordability mandates without compromising luxury, we engineered "hidden density" through micro-unit transformable walls that expand studio apartments into 2-bedroom layouts.

Results & Legacy

Today, Eden stands as SF's first Net-Zero residential high-rise, where 1.2MW solar skin generates surplus energy sold back to the grid. Residents enjoy 75% lower utility bills through geothermal heating and smart-home systems that learn occupancy patterns. The development's crowning achievement? Its closed-loop hydronics: 95% of rainwater is captured for irrigation and cooling towers, while blackwater treatment irrigates the vertical food forest producing 8 tons of annual produce for residents.
