Case Study
Flexibility key to successful stadium installation
ELECTRICAL ENGINEERING, SYSTEMS INTEGRATION AND INSTALLATION SPECIALIST MIZCO HAD THE CHALLENGING TASK OF PROVIDING THE HVAC CONTROLS SYSTEM FOR THE BILLION DOLLAR-PLUS OPTUS STADIUM IN PERTH.
THE STADIUM WAS a mammoth build which involved 36 months of construction to create the third largest stadium in Australia capable of seating up to 70,000 people.
More than 5,800 workers were directly em- ployed during construction of the stadium which took more than 21 Olympic sized pools of concrete to build.
It officially opened earlier this year and is one of the largest commercial projects undertaken by MizCo who were engaged by stadium build- er, Multiplex.
MizCo director, Greg Mizza, said the focus was on ensuring the venue featured the latest in innovation, design and technology.
“We were encouraged to break away from tradi- tion and introduce cutting edge technology,” he said. MizCo considered several unique factors when designing the HVAC control system for its
maiden stadium project.
“The key challenge was understanding the complex communication protocols and techni- cal requirements of the converged network/ICT,” Mizza said.
“The HVAC control system needed to oper- ate seamlessly with this network and as a standalone.
“With more than 400 variable speed drives to be installed and integrated within the backbone network, we invested a significant amount of time finding a product that would work into the control system and allow the team to deliver the project with maxi- mum efficiency.”
Prior to selecting Eaton as the drive partner, MizCo tested several different variable speed drive products and measured them against the following stadium scenarios: Conductivity at an Ethernet, BACnet/MS/TP and BACnet/IP level and serviceability.
