Testa Produce, Chicago, IL
Completion Date: Fall 2010
Roofmeadow Network contractor: Robert Ebl, Inc.
Snowing…in Chicago…in June! No I don’t think so, but it sure looked like it up on the Testa Produce green roof today. When I arrived on site this morning the air was filled with the cotton ball lookalike seedlings of the Cottonwood Tree (Populus deltoids).
The Testa green roof is an engineering masterpiece. The “barrel” section of the roof is stabilized with a cellular confinement system.
The cellular confinement web is in turn supported by the weight of the adjacent flat extensive green roof, without the aid of any fixed anchors to the building structure. The mass of green roof media supported in this way is over 90 tons. This Roofmeadow Type II 4.00 inch thick green roof profile has a maximum pitch of 43 degrees. Pre-grown sedum mats were used to establish plant coverage on this section of the green roof and an irrigation system has been incorporated.
The 30,000 square foot, 3.00 inch thick flat green roof area was established with sedum cuttings and plugs.
This roof was planted in the fall of 2010 and already you can see the sedum cuttings poking through the temporary wind blanket with force!
This green roof is right on track and has appropriate coverage for its age.
The Testa Produce corporate headquarters, located in the old Chicago Union Stockyards, is in every way a “green” building. Not only is rain water that drains from the green roof recycled and reused for non-potable uses throughout the building, Testa also has the first free standing wind turbine in the City of Chicago.
