Type II - 3.00 - 4.00 inches of media
Located in the old Union Stockyards complex on the outskirts of Chicago, this green roof was designed by Roofmeadow and installed by Roofmeadow contractor, Robert Ebl Inc. for Testa Produce’s new corporate headquarters and distribution facility. The green roof includes a 7,500 square foot barrel roof at the face of the building. The 4.00 inch thick profile on the barrel roof has a maximum pitch of 43 degrees. The media on the barrel 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 the media supported in this way is over 90 tons. Custom pre-grown reinforced sedum mats were used to plant the barrel portion of the green roof. This is the first time that this approach to slope stabilization has been implemented on such a large scale. The 3 inch thick 30,000 square feet flat roof was planted with Sedum plugs.
Once a brownfield site, the building is now LEED Platinum making it the first industrial building to achieve that status. The facility also includes a wind turbine, a solar hot water system, recycled concrete, LED lighting and solar tracking skylights.
