Forward thinking sustainability solutions

Brisbane Catholic Education’s forward thinking sustainability program includes the installation of geothermal air conditioning in their schools across South East Queensland.

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

Ongoing energy efficiency benefits

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.
