Final Presentation

  1. 1. Opportunities for Sustainable Land, Energy, and Water Improvements at LP Field -Analysis conducted by Scott Thorpe
  2. 2. Presentation Overview • LP Field Complex Basic Site Analysis • Discuss Sustainable land use applications focusing on efficiency, conservation, reuse, and restorative practices to transform LP Field and its effects on and interactions with surrounding community. • How this transformation will save valuable natural resources and millions of dollars
  3. 3. GENERAL INFORMATION • Metropolitan Sports Authority/Titans • Built by HOK Sports Facilities Group of Kansas City, Mo in 1999 • The LP Field was completed at an estimated cost of $292 million. Actual construction costs stand at approximately $165. Metro Davidson County government provided some $154 million in financing, PSL sales contributed $71 million, and the State, some $67 million.
  4. 4. GENERAL INFO (CONTINUED) • The LP Field Complex covers some 120 acres. There are 7,500 parking spaces on the grounds. The concept of the complex: a park. More than 200 trees have been planted. • Some 800,000 cubic yards in concrete were used to build the stadium, which numbers some 1.5 million square feet. The stadium stands 190 feet high.
  5. 5. GENERAL INFO (CONTINUED) • 60 concession stands, 11 Novelty stands, 54 water fountains. The LP Field has 40 women’s restrooms, 26 men and 12 family restrooms There are over 1200 toilets and urinals inside the complex. • Seating: The LP Field seats 67,700 fans. There are: 143 luxury suites, 11,492 Club Level seats 25,198 Upper Deck seats, 26,504 Lower Level seats. With team personnel and vendors, game day attendance reaches nearly 70,000.
  6. 6. Look at the facility as two separate entities; the parking lots and the building itself
  7. 7. PARKING LOT OPPORTUNTIES Sustainable Land Use Alternatives would meet many goals: • improving water quality and storm water control • reducing maintenance and urban heat island • providing wildlife habitats • generating renewable energy • improving aesthetics • all while providing for public education about sustainability.
  8. 8. Installing pervious pavement is the foundation for improving the parking lots.
  9. 9. WATER BENEFITS • Reduce the amount of untreated runoff discharging into storm sewers. • Directly recharge groundwater to maintain aquifer levels. • Channel more water to tree roots and landscaping, so there is less need for irrigation. • Mitigate pollutants that can contaminate watersheds and harm sensitive ecosystems. • Eliminate hydrocarbon pollution from asphalt pavements and sealers.
  10. 10. LAND/ENERGY BENEFITS • Aid in reducing the urban heat-island effect. • light color & open-cell structure = don't absorb and store heat and radiate it back into the environment like a typical asphalt surface. The open void structure also allows cooler earth temperatures from below to cool the pavement. • The lighter color of concrete is also beneficial from an energy-savings standpoint. Because the concrete is reflective, the need for lighting at night is reduced. • Beyond helping the environment, also safer for drivers and pedestrians. Absorbs water rather than allowing it to puddle, reduces hydroplaning and tire spray.
  11. 11. LAND/ENERGY BENEFITS • Allow for the restorative practice of planting trees and other native vegetation. Because the surface would be porous, air and water needed for plant roots could be more easily provided, and designed to channel more water to tree roots and landscaping, so there is less need for irrigation. • Plantings could be strategically without losing a single parking spot and serve as a wildlife habitat for local species.
  12. 12. Strategically located plantings along the south and west end of the facility could also serve to help re-establish the riparian zone between the facility and the river.
  13. 13. ECONOMIC BENEFITS • Lower installation costs- installing traditional systems can cost 2 to 3 times more than low-impact strategies such as pervious concrete. • Permits the use of existing sewer systems- reduce the need for municipalities to rebuild/increase the size of existing storm sewer systems. Saves $4800 annually in Metro stormwater fees. • Increased land utilization- there is no need to purchase additional land for installing large retention ponds and other water-retention and filtering systems. • Lower life-cycle costs
  14. 14. SOUNDS GREAT!!! But what if I don’t want to excavate?
  16. 16. Solar Applications for Parking Lots Replace generator run and grid tied lighting with solar Install PV parking canopies power lights
  17. 17. Solar Canopy Examples Fresno State University's 700 Google's corporate hundred parking spot 1MW headquarters' 1.6 MW system capacity • Google is interested in the financial benefits ,but also • Chevron's Energy Solutions, sees that installing solar panels who partnered with Fresno as "parking lot installations are State on the project, estimates a visible demonstration of the that FSU will save $13 million company's commitment to the in utility costs over the next 30 environment. You can talk years. about your energy savings, your recycling and green practices, but the sight of solar panels in the parking lot is an emblem of that commitment!"
  18. 18. Let’s Go Inside
  19. 19. Easy & Inexpensive Fixes -ENERGY MASTIC APPLICATION- Typical OCCUPANCY SENSORS FOR commercial air ducts leak over LIGHTING & CLIMATE 15%! CONTROL Using occupancy sensors can eliminate 20% – 80% of lighting energy costs. Sealing leaking air ducts saves energy, saves money, improves indoor comfort and indoor air quality.
  20. 20. Easy & Inexpensive Fixes- ENERGY Compact Fluorescent Light bulbs (CFLs) use 75 percent less than their incandescent counterparts. Besides, this energy-saving light bulb lasts up to ten times longer and prevents over 450 pounds of greenhouse gas emissions from polluting the atmosphere. A single CFL can save you more than $80 over its lifetime depending on local electric rates.
  21. 21. …Even more efficient lighting The Specific Benefits of LED Light Energy efficiency – The light bulbs burn very cool, while incandescent bulbs emit 98 per cent of their energy as heat! Much more bang for the buck. Long life – These lights can last from 50,000 to 100,000 hours. Incandescent light bulbs typically last around 1,000 hours and fluorescents are good for roughly 10,000 hours. Rugged durability – LED lights have no fragile filament to contend with, and no fragile tube. They are resistant to heat, cold, and shock
  22. 22. STADIUM WATER SAVINGS SOIL MOISTURE SENSORS DRIP IRRIGATION Evaluate optimum soil moisture contents The low application rate and the use of for various species of plants. automatic timers results in precise water Monitor soil moisture content to control control. irrigation in greenhouses. Weed growth is reduced because areas Manage garden soil moisture between plants are not irrigated.
  23. 23. Rainwater Harvesting -Reduces volume of water flowing to sewer treatment facility -Lowers the percentage of roof top rainfall as a component of urban runoff -Backup source of water during times of drought or between rain showers -Saves money by lowering your water bill -Reduces the need for additional tax dollars earmarked for sewer expansion -Chlorine-free water helps maintain a healthy biotic community in the soil -Educational tool for teaching residents about water conservation
  26. 26. UNDERPROMISE & OVERDELIVER • Savings were calculated “…using the most conservative estimations to reduce overstatement …and allow for the improvements suggested to be considered the lower limit of actual outcomes” (J. Gowdy. P3, “Final Report for Morgan Park Place”)
  27. 27. What does this water footprint reduction equate to? • Nearly 70,000 fans in a stadium on a game day = 600,000 to 1 million gallons consumed/used • 12 million gallons of water are consumed during the 20 highly attended events, plus another 6 million for the day to day operations, totaling 18 million gallons conservatively. • According to Metro Water of Nashville, the average price of per gallon of water is $0.0028. If that number is multiplied by the conservative annual estimated water use of LP Field, 18 million gallons, the total cost is $50,400. • A water management plan integrating the applications mentioned could generate a savings of $25,000 annually just off purchasing fresh water, • Include the cost reduction expected from reduced storm water and sewage fees (5-6000 dollars) and savings go beyond $30,000. • Environmental benefits saving literally millions (8-10) of gallons of water!!!
  28. 28. What does this energy footprint reduction equate to? • A football stadium that seats approximately 70,000 fans will consume about 65,000 kilowatt hours of electricity on game day • To calculate the energy footprint, that 65,000 kilowatt hours can be multiplied by 20, representing the number of football games and concert events that are highly attended, which equals 1,300,000 kilowatt hours • The estimate for day to day operations for an entire year is equivalent to 100 game days, or 6,500,000 kilowatt hours • Totaling an energy footprint of 9,800,000 kilowatt hours conservatively. • Charging a conservative average rate of 8 cents per kilowatt hour equals a cost of $784,000 annually
  29. 29. ENERGY SAVINGS WILL VARY GREATLY • Application of mastic where needed, the installation of highly efficient lighting and HVAC systems that take advantage of occupancy sensors, and replacing light bulbs with CFL or LED technologies will result in a 15-30% reduction (1,470,000- 2,940,000 kilowatt hours) = $117,600-235,200 saved
  30. 30. Savings from Solar Canopy Application • Solar canopy array could create enough self- generated electricity to power the entire stadium’s needs and even supply excess energy to Metro Nashville. • Copy Fresno State University system that covers 700 parking spots and has a capacity of 1MW. • The LP Field lots contain 7000 spots, which could have a capacity for 10MW generation. Obviously such an installation would drastically reduce the costs and amounts of energy currently used at the stadium. • Generate 12 million kilowatt hours/year. Generate $2,640,000 annually. Cost is +/- $56,000,000 • Another sports stadium example for taking advantage of solar electricity is currently under construction for the New York Jets new 75,000 seat facility. According to William Pederson of Kohn, Pederson, and Fox, the architecture firm designing the stadium, the solar cells are expected to provide all of the stadium’s power and also supply energy to the surrounding West Side.
  31. 31. “Best Practices” of other NFL Organizations • Philadelphia Eagles 2008 Go Green Program Update • Since initiating the GO GREEN program in 2003, the Philadelphia Eagles have made enormous strides in reducing the organization's impact on the environment by: • Running on 100% clean energy after purchasing 14 million kilowatt- hours of renewable wind energy. • Implementing energy conservation programs reducing electricity consumption at Lincoln Financial Field by more than 33%. • Installing three state-of-the-art solar panels that track the sun throughout the day and produce 10kW of energy. • Implementing an employee reimbursement program to encourage employees to switch from conventional power to wind energy. The participating employees are eliminating the emissions of 283 tons of greenhouse gas emissions each year.
  32. 32. CONCLUSION • Financially it is very possible to save 30-50% on both water and energy costs • Solar Canopy could generate additional revenue • Combined bottom line impact annually anywhere from $2- 3,000,000. • Environmental Benefits would save millions of gallons of water and kilowatt hours
