Project Scope: After demand by surrounding area residents, Metro Parks recently enhanced the Stones River Greenway by adding a 1,000 sq. ft. structure that includes permanent public restrooms, seasonal concessions, bike and canoe rentals, a food truck plaza and a 2.5-acre dog park at the J. Percy Priest Trailhead entrance located at 2778 Bell Rd. the Stones River Greenway is a 10.2-mile paved trail system that runs parallel to Stones River throughout the city of Nashville that links schools, shopping areas, businesses and other points of interest to travelers and provides access to a number of communities and parks along the way.
The new buildings are comprised of four shipping containers and a steel canopy. Two containers that make up the public restrooms are 20’ long, while the two containers for the concessions and canoe storage are 40’ long. To ensure that the building’s design quality and green initiative were still intact, the choice to reuse shipping containers allowed for a not only a low energy alternative to traditional building materials, but also reduced purchasing costs of repurposed and recycled containers.
This project further decreased its carbon footprint by working with designers and contractors, including RSS Roofing Services & Solutions, a commercial roofing contractor with a location in Nashville, to install a cool roof membrane on the buildings. RSS installed tapered polyiso insulation over the containers which were then covered with a fully-adhered white 60-mil TPO membrane roofing system. By installing this type of reflective roofing system, the repurposed storage containers increase the facility’s energy efficiency even more.
Mandated by IECC building code 2012 with a recommended R-value of R-25, RSS provided the Stones River Greenway buildings with a roof membrane that will withstand long-term heat and UV resistance, reduce energy costs and urban heat island effect, and minimize thermal drift.
The tapered polyiso insulation is EPA-compliant, delivers zero ozone depletion potential and hardly any global warming potential. The insulation also provides exceptional thermal performance at an economical price and helps eliminate ponding water issues. Lastly, due to its lightweight features, the installation is fast and easy, allowing for decreased labor costs.
