The Nashville Sounds baseball fans will find themselves under a LiveRoof® living roof system when they step up to the new concession area for hotdogs and peanuts when First Tennessee Park opens on April 17.
Nashville, TN — April 2, 2015 — As Nashville Sounds baseball fans eagerly await the famous words “Play Ball,” construction crews are putting the finishing touches, including a green roof feature, on the new First Tennessee Park. The state-of-the-art ballpark is slated to open for Mayor Karl Dean’s first pitch on April 17.
The First Tennessee Park is part of a mixed-use development in the Sulphur Dell area – once the home to the first professional baseball team in Nashville, the Elite Giants, and several minor league teams.
As part of the city’s newest venue, Mayor Karl Dean wanted to showcase the best of current sustainability infrastructure. A new greenway will offer easy pedestrian access and enhance the ballpark’s park-like feel. On Monday, April 6, Southeast Green Roofs, LLC of Fairview, will deliver a LiveRoof hybrid green roof system to cover the concession area. While it will not be accessible to ballpark fans and guests, it will be visible.
“Nashville has positioned itself to be a leader in providing green ways to its residents and visitors,” said Andy Sudbrock, president of Southeast Green Roofs. “First Tennessee Park’s inclusion of a visible green roof is a demonstration of the city’s commitment to sustainability, and as a local company, we’re proud to be a part of the project.”
Landscape Architect Bram Barth, of Lose & Associates, designed the project. The planted roof will contain primarily drought tolerant and hardy Sedum, a type of low-growing succulents. Baker Roofing installed the 1500 square foot green roof, along with 220 square feet of natural-colored pavers to serve as a maintenance path.
Green roofs provide nature function and beauty. A patented, subterranean modular system unites the soil and plants creating a naturally beautiful meadow-like aesthetic. The roofs provide aesthetic, environmental and social benefits (See Sidebar 1).
Financial benefits can also be achieved from a vegetative roof including: extension of roof life, energy conservation, enhanced public relations, and conservation of municipal septic systems. (See Sidebar 2).
Green Roof Benefits
Better Stormwater Management: Immediate stormwater runoff reduced by 50-90 percent. Green roofs filter rainwater water and act as a buffer against acid rain.
Longer Roof Life: Plants and soil serve as a protective shield and prevent UV radiation from degrading roof components. Fewer cracks and leaks. Waterproof membranes can last 200-300 percent longer.
Energy Conservation: On a sunny 95°F day, conventional rooftop surfaces can hit 175°F. By shading and insulating the rooftop, green roofs bring these temperatures in line with the ambient air temperature. They reduce indoor temperatures and energy consumption, especially for air condtioning in summer. That decreases costs for building owners.
Interior Noise Reduction: Lower indoor sound levels, as much as 40 decibels.
Urban Heat Island Effect Mitigation: Plants release oxygen and evaporate water. Green roof soil also evaporates water. That makes a green roof function like an evaporative cooling system. The combination of the umbrella effect (shading and insulating) and evaporative cooling moderate temperatures at street level.
Improved Air Quality: Every one square foot of green roof can filter about seven ounces of dust and smog particles per year. And through the process of photosynthesis, plants covert carbon dioxide, water and sunlight/energy into oxygen and glucose. This results in reduction of greenhouse gases in the atmosphere.
Enhanced Aesthetics: Green space is visually appealing and inviting. People feel better and are more productive when they have a natural view. Barren rooftops become habitable spaces with walkways, patios and seating and thereby add useable space to buildings.
Business Benefits: the Main Drivers for Building Green
Reduction in Operating Costs: On average, 13.6 percent for new buildings and 8.5 percent for retrofits
Increase in Building Values: On average, 10.9 percent for new buildings and 6.8 percent for retrofits
Increase in Return on Investment (ROI): On average, 9.9 percent for new buildings and 19.2 percent for retrofits.
