MORE GREEN, LESS WEIGHT, WIN-WIN FOR GREEN ROOFS

Chicago may favor deep-dish for its pizza, but a company is going thin crust for its green roofs and living walls. The Omni Ecosystems Green Roof technology grows more plant options in half the weight of conventional green roof systems. With installations in Chicago the system is clearly being tested under some of the harsher conditions in the U.S (hot summers, cold winters, high winds). The benefit of the lighter weight and more concentrated plant diversity is wider applicability on existing buildings where significant structural upgrades to the roof may not be possible. The same technology is applied to their living walls, with equally appealing financial benefits:

“Whereas most living wall products require constant plant replacement - as much as 100 percent every six months - our system has required less than six percent in the 18 months since installation”

Whether these claims bear the test of time, their next partnership is exciting in that it sets up a PPA-like relationship between roof owners and a group called Roof Crop:

“Building owners meet their green roof obligations for sustainable development in the City of Chicago, receive rent from The Roof Crop as the “roof tenant,” and have a reliably maintained green roof. The net effect is a green roof that pays for itself and is truly maintenance-free for the building owner”

Their first leased rooftop farm was recently installed in Chicago’s West Loop neighborhood.
