HVAC Case Study
South Australian Sport Institute

The new SASI complex will include:

• Strength and conditioning gym capable of accommodating multiple sports and teams
• Specially designed indoor court with smart technology
• Sport specific ergometer training zones
• Indoor bounding areas
• Environment chamber for simulated heat, humidity and altitude stress training

Project Requirements

The project aims to install and integrate Indirect Evaporative Cooling (IEC) units to improve energy efficiency, air quality, and comfort levels for two specific spaces: a Court and a Movement Studio.

1. Installation of standalone IEC units for the basketball court:
   • Design and install an indirect evaporative cooling (IEC) system as the primary cooling solution for the netball court.
   • Ensure that the system can operate independently, maintaining optimal temperature and air quality for the occupants.
2. Duct Heaters Integration with IEC System for the Court:
   • Integrate duct heaters with the indirect evaporative cooling system in the basketball court to provide heating capacity when needed.
   • Ensure seamless operation of the heaters and IEC system to maintain desired climate control parameters.
3. Precooling Integration to the air handling unit for the Movement Studio:
   • Install an indirect-direct evaporative cooling (IDEC) system to precool outside air for the new air handling systems before it enters the Movement Studio to optimise indoor temperature and reduce energy consumption.
4. Control and Interface Requirements:
   • Ensure compatibility with building management systems (BMS) or other control platforms for remote access and automation.

The Solution

The installation of an advanced Indirect Evaporative Cooling (IEC) system as a standalone solution for the court to ensure optimal cooling performance with high energy efficiency. The system is supplemented with high-capacity ducted heaters, integrated into the IEC, providing precise temperature control throughout the court, even in cooler months.

For the adjacent Movement Studio, an IDEC system designed to pre-cool incoming outside air was installed. This will enhance indoor comfort, particularly during high activity periods, while maintaining energy efficiency and reducing cooling loads.

All installed IEC\IDEC systems are centrally controlled by seamlessly integrating each unit’s PLC controller, with the building management systems (BMS), allowing full control over system settings, performance monitoring, and operational flexibility. This ensures tailored comfort and energy management across all spaces.
