The LiveRoof Hybrid Green Roof System will be installed for the Chattanooga City Council Building. The system will be installed by Southeast Green Roofs who is the authorised regional grower and distributor for LiveRoof.
The company has already started growing the plant modules for this purpose. Once the green roof is installed, it is will provide important benefits to the building in terms of storm water management and increasing the service life of the City Council building.
At present, the city’s sanitary sewer and storm water system combine and lead to the cavern below ground level. These caverns lead the water to the Moccasin Bend Sewage Treatment Plant. Excess runoff of water caused by harsh storms overflows and contaminates the Tennessee River.
According to Andy Sudbrock, plant ecologist at Southeast Green Roofs, a green roof has the ability to absorb and reduce the excess flow of storm water and protects the roof during extreme weather conditions. The LiveRoof System uses the Moisture Portal and Soil Elevator features to combine them as one ecosystem. The Soil Elevator is a removable lining inside the modules on top on which soil can be filled. The Moisture Portal is the opening on the sides of the module through which soil-to-soil contact can be maintained in modules.
LiveRoof systems have been installed in various other building in the Chattanooga area. Particular examples are the 3,800 sq. ft. green roof for the Creative Discovery Museum in 2010, the 1,500 sq. ft. green roof for Hamilton County Health Department, and the 2,200 sq. ft. green roof for Mary Walker Towers.
