Marlins Park - TraneDelorme, Executive Vice President, Miami Marlins Operations and Events. "For us to maintain a comfortable temperature Marlins Park Energy efficient systems help

ChallengeWith millions of South Florida residents and visitors, the

Miami Marlins potential for economic success is great. In the

past, however, frequent rain and high afternoon temperatures

discouraged many fans from including a ballgame in their

entertainment plans.

To draw more attendance, Miami-Dade County moved

forward with plans to build a retractable roof ballpark. The

state-of-the-art roof would eliminate rainouts and weather

delays, and ensure the comfort of fans. When conditions are

favorable, the roof can be opened to allow visitors to enjoy

the Florida sunshine. In the event of inclement weather, the

roof can be closed to keep guests safe and comfortable.

In building the facility, Miami-Dade County and the City of

Miami required that its sustainability objectives were met, and

asked the Marlins to deliver a ballpark with LEED Silver

certification. LEED promotes a whole-building approach to

sustainability by recognizing performance in five key areas:

site development, water savings, energy efficiency, materials

selection and indoor environmental quality.

"Optimizing energy performance was the most difficult

benchmark because of the retractable roof," said Claude

Delorme, Executive Vice President, Miami Marlins Operations

and Events. "For us to maintain a comfortable temperature

A first-class ballpark owned by Miami-Dade County, Marlins Park is located on approximately seventeen acres in theLittle Havana section of Miami. With an aggressive waste management recycling program, the use of locallymanufactured materials and low volatile organic compounds (VOC) in its construction, a minimizing of artificial lightand the incorporation of energy efficient systems, the ballpark has become the first professional sports facility with aretractable roof, in the world, to attain Leadership in Energy and Environmental Design (LEED) Gold certification.

for our local guests and out-of-town visitors, we had to be

very efficient with all our systems."

SolutionHaving worked with Trane on several projects in the past,

Hunt/Moss, A Joint Venture called on Trane to provide the

energy efficient equipment to help the project achieve its

sustainability goals and earn LEED certification points. With

extensive ballpark project experience, Trane understood the

requirements of cooling a large open space, and the added

challenge of optimizing energy performance with a

retractable roof.

The Marlins ballpark has 37,442 seats, a natural grass playing field and

a retractable roof.

Creating a cool, comfortable environment

Two energy efficient Trane 3,200-ton CenTraVac™ chillers

and one Trane 400-ton air cooled rotary chiller were installed

to help the ballpark maintain the venue’s seventy-five degree

average temperature requirement, as well as optimal

ventilation and humidity levels. To remove heat from the

ballpark, chilled water is piped to fifty air handling units,

which service the entire facility. The air handlers are designed

with energy recovery and variable frequency drives to monitor

motor speed and load, helping to minimize energy

consumption and maximize energy savings.

Controlling systems and costs

Variable-air-volume terminal units continuously monitor the

amount of delivered airflow and communicate this

information to the Trane Tracer Summit® building automation

system (BAS). The BAS system provides integrated building

control through a dedicated PC workstation. Building

engineers use the BAS to program and manage the chillers

and cooling towers to ensure that all systems are running

efficiently to control energy costs and fan comfort.

Systems and services

• One 400-ton air cooled rotary chiller

• Two 3,200-ton Trane CenTraVac™ chillers

• Thirty-one dehumidification air handling units

• 358 BCHC blower coil units

• Thirty-nine variable-air-volume terminal units

• Trane Tracer Summit® building automation system

ResultsThe new Marlins Park has received the prestigious honor of a

LEED Gold certification, the first professional sports facility in

the world with a retractable roof to be awarded this

certification. Environmentally conscious construction

practices met LEED requirements including a 52 percent

reduction in water use, 98 percent recycled construction

waste and 50.9 percent recycled building materials content,

with 48 percent of the materials used during the construction

obtained within 500 miles of the jobsite. The energy efficient

Trane HVAC solutions helped the ballpark achieve the LEED

energy efficiency credits necessary for certification.

"This was really a collective effort," said Delorme. "It wasn’t

the Miami Marlins saying we want a green building. It was

everyone - the community, the owners, the construction firm

- all stepping forward wanting to be a part of it, with benefits

for everyone."

With the retractable roof and the reliable Trane HVAC system

with Tracer Summit BAS, the environment at the ballpark is

always sunny, cool and comfortable for local fans and visitors.

Rainouts and rain delays have been eliminated and fans are

assured that games will start on time.

To remove heat from the ballpark, chilled water is piped to fifty air

handling units which service the entire Miami Marlins facility.
