Case Study
STADIUM SEATING SOLUTION
Hassell, Cox Architecture, and HKS Sport and Entertainment, as part of the Westadium consortium, won a competition to design the publicly funded stadium – which sits adjacent to the Perth CBD on the Burswood Peninsula.
Featuring a round design, the stadium consists of tiered seating located above bars and restaurants in the levels below.
The unique design called for a slim profile thermal solution capable of meeting the limited space allocation while still delivering on the high energy efficiency requirements of the project.
The Kingspan Insulation technical team, along with the project’s contractors at Cubic Group, designed a customised installation solution that could be applied to the underside of the seating plats. Kingspan’s insulation was used for soffit and ducting applications.
Over 2,000m2 of Kingspan KoolDuct was used to create lightweight cushion heads and plenum boxes for the stadium’s HVAC system. A flourish of innovation for the versatile KoolDuct product also sees it lining the ice troughs in the facility’s bars and restaurants.
The facility’s bronze facade is made of anodised aluminium and reflects the state’s unique geology. LED lighting to show the home-team colours is woven through the structure and is a testament to the “fan first” approach.
Kingspan products used in the project included Kooltherm K10 FM soffit boards, Kooltherm K10 White soffit boards and KoolDuct high performance rigid pre-insulated ductwork.

“MORE THAN 400 VARIABLE SPEED DRIVES HAD TO BE INSTALLED AND INTEGRATED WITHIN THE BACKBONE NETWORK.”
- MIZCO DIRECTOR, GREG MIZZA
“The Eaton H-MAX series of drives, with BAC- net/IP communications onboard was selected based on its strong capability and cost benefit,” Mizza said.
Working closely with Eaton’s local team and US-based experts, MizCo was able to enhance theH-MAXdrivesbydevelopingnewsoftware configurations and product changes that helped streamline the physical installation.
“We were impressed by Eaton’s flexibility and responsiveness during this phase. These en- hancements have now become normal practice at Eaton,” Mizza explained.
The MizCo team installed 410 Eaton H-MAX variable drives across the stadium infrastruc- ture. This is the largest single install of this prod- uct anywhere in the world.
With Eaton’s Max Connect drives software, the HVAC control system was set up to display the parameters of all drives in real-time from one location.
Eaton’s built-in Active Energy Control soft- ware provides management capabilities that reduce the input voltage and current require- ments to maintain system speed and torque de- mands – setting a new standard in energy opti- misation and stability, while delivering additional cost savings.
The HVAC control system designed by the
MizCo team also featured multiple access points across the stadium in the form of touch screens for local/remote control management giving the maintenance and service team capabilities to access live information.
While MizCo expects it to take a little while before the technology and systems are operating at optimum efficiency and productivity, initial feedback shows that the HVAC drive system is working as designed and delivering the client’s requested outcomes.
Contracted for three-years to support the on- going service and maintenance of the HVAC con- trol system at Optus Stadium, MizCo is keen to maximise the benefits of Eaton’s integrated soft- ware to deliver more efficiencies and minimise running costs.
Afterthesuccessofthisproject,Eatonhas also appointed MizCo as an Eaton drives inte- gration partner. ✺
