• How this transformation will save
valuable natural resources and
millions of dollars
• 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.
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.
GENERAL INFO (CONTINUED)
• 60 concession stands, 11 Novelty stands, 54
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.
Look at the facility as two separate entities;
the parking lots and the building itself
PARKING LOT OPPORTUNTIES
Sustainable Land Use Alternatives would meet
• 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
Installing pervious pavement is the
foundation for improving the
• Reduce the amount of untreated runoff discharging
into storm sewers.
• Directly recharge groundwater to maintain aquifer
• 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.
• 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
• 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.
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.
• 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
• Lower life-cycle costs
But what if I don’t want to

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.
…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
Rugged durability – LED lights have no
fragile filament to contend with, and no
fragile tube. They are resistant to heat,
cold, and shock

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”)
What does this water footprint
reduction equate to?
• Nearly 70,000 fans in a stadium on a game day = 600,000 to 1 million
• 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
• 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!!!
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
ENERGY SAVINGS WILL VARY
• 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
Savings from Solar Canopy
• Solar canopy array could create enough self- generated electricity to
power the entire stadium’s needs and even supply excess energy to Metro
• 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.
