Cranbrook Private School - Bellevue Hill, Sydney, NSW, Australia

Cranbrook is an Anglican independent day and boarding school for boys, from pre-school to Year 12. The esteemed Sydney school's significant redevelopment and renewal of its aging senior campus at Bellevue Hill is the single most ambitious and visionary project to be undertaken in the school's history.

The $125 million dollar redevelopment involved the replacement of buildings, some of which have been in use for more than 70 years. It also included digging up the senior school’s Horden Oval to build the underground aquatic and fitness center, which features an Olympic-sized swimming pool, along with a 126-space car park. The redevelopment also incorporates a drama and music theatre, multi-level contemporary education building, dining commons, multi-use assembly hall, theatre, indoor basketball courts, and chapel.

Why Distech Controls technology?

ControlWorks worked with ICR Mechanical to engineer and install a building automation system, based on Distech Controls' Niagara N4 Supervisor and Graphics platform. ControlWorks previously provided a similar system for Cranbrook's nearby junior school campus.

The flexible Distech Controls' Niagara N4 Supervisor and Graphics system provide the school with a web-based, graphical user interface. This makes it easy to access real-time HVAC monitoring and control via a web browser, from any computer connected to the school's IT network. The password-protected, easy-to-use interface allows the school's engineering and facilities management staff to operate and manage the HVAC system with minimal reliance on the vendor.

Ventilation:

Along with offering energy efficiencies and savings, the system also provides advanced features such as temperature, humidity, and CO2 monitoring to ensure classroom air quality and provide adequate ventilation. The system ensures that all indoor areas regularly cycle their air, and can automatically notify teachers of the need to open classroom windows or adjust the air conditioning.

The solution provides natural ventilation to classrooms and the basketball court in Cranbrook's Centenary Building for considerable energy savings. It monitors conditions both inside and out, thanks to an outdoor weather station, and automatically adjusts motorized louvers to ensure optimal indoor conditions.

Condensation:

The Olympic swimming pool in Cranbrook's new aquatic and fitness center is heated through the use of heat pumps, or by gas-fired hot water generators from the main plant.

ControlWorks's solution takes advantage of specialized pool Air Handling Units to avoid condensation on the pool area windows. Tightly controlling the temperature, air movement, and humidity in the pool area, such solutions are more common in public aquatic centers than in schools.

An air heat exchanger also delivers energy savings by controlling the air temperature to keep it a steady 2 degrees Celsius above the pool water temperature.
