SUSTAINABILITY | Geothermal Installation at Mt Maria College


Using Mt Maria College as the pilot school, Brisbane Catholic Education engaged Calibre to undertake a complete review of mechanical and electrical infrastructure at the school.

The College commenced an air conditioning program for the entire campus and required a solution that would provide ongoing energy efficiency benefits.

Geothermal air conditioning was selected for its high efficiency and reduction of peak load demands to the site.

Project highlights include:

  • High efficiency system with potential cost recovery in approximately four years based on monitoring results.
  • 13kW and 14kW ducted geothermal systems installed across two newly constructed buildings including a state-of-the-art performing arts block.
  • In ground geothermal infrastructure was installed for an additional 16 classrooms and the school’s administration building and library.
