If you don’t have rocks in your head, perhaps you should. A prestigious South Australian private boys’ school is expecting to save more than a third of its energy costs by harnessing the earth’s warmth to heat and cool its sports centre.

In a South Australian first, St Peter’s College, Adelaide, is installing a geoexchange heating and cooling system for its indoor pool and enclosure.

The geoexchange system, supplied by GeoExchange Australia, taps into the ground’s stable temperatures to increase the efficiency of heating and cooling systems. A Ground Heat Exchanger (GHX) will use ground temperatures of 17°C via 45 boreholes drilled 70 m down into the earth beneath the sports oval.

Water is circulated through polyethylene pipe within the GHX, extracting heat from the ground and delivering it to a series of ground source heat pumps (GSHPs) in the main plant room. Two of the GSHPs will transfer the heat from the GHX into the pool water, while four other GSHPs will supply heating and/or cooling to the pool enclosure.

“Schools have a leading role to play in the necessary transition to a clean energy future and St Peter’s College has embraced this responsibility,” said Yale Carden, managing director of GeoExchange Australia.

“Their leading role is an important element in assisting the South Australian Government achieve their stated target of Adelaide being a carbon neutral city by 2050.”

The installation of a geothermal energy solution aligns with the school’s vision for sustainability, outlined in its strategic plan, ‘Our Preferred Future 2015–2018’.

“Environmental sustainability is one of the world’s greatest challenges and we must all do what we can to address this global issue — we must focus on minimising our carbon emissions and environmental footprint through energy, water consumption and waste recycling,” said Jason Haseldine, director of finance and administration at St Peter’s.

“As a school, these works are also significant for our students — they will help us, as educators, continue to lead by example for our boys and educate them about living sustainably so they develop into environmentally responsible adults.”
