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
Marlins ParkEnergy efficient systems help achieve LEED Gold certificationMiami, Florida
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.
