MIAMI—Swire Properties is putting an eco-friendly stamp on its billion-dollar Brickell CityCentre Project. It's called the Climate Ribbon.

Composed of steel, fabric and a continuous surface of glass, the Climate Ribbon is an elevated trellis that will span 150,000 square feet connecting all parcels of the mixed-use Brickell CityCentre. Swire is investing $20 million to create what it calls a “comfortable microclimate for shoppers through the use of passive energy devices.”

The Climate Ribbon aims to serves multiple purposes: acting as a shade for the project's walkways, shops, restaurants, escalators and terraces to protect visitors from rain and sunlight; creating air flow to optimize temperatures and collecting rainwater for reuse; and allowing Brickell CityCentre shopping to be open air and naturally lit.
