Presentation in my role as Founding President of the Australasian Ground Source Heat Pump Association (AGSHPA). AGSHPA is our local chapter of the International Ground Source Heat Pump Association (IGSHPA). Awkward acronyms but we will work with what we have.

The focus of this presentation was to provide a snapshot of the geoexchange or ground source heat pump industry in Australia and New Zealand.

IGSHPA Presentation: Las Vegas, October 2013

  1. 1. GEO Down Under – The Ground Source Industry in Australia and New Zealand Prepared by: Yale Carden President, Australasian Ground Source Heat Pump Association Managing Director – GeoExchange Australia Pty Ltd
  2. 2. Outline  Embrace The Differences  Country Snapshot  Australia  New Zealand  History  Why the Australasian GSHPA?  Standards: Existing and Future  Research Institutions  Case Studies  Opportunities GEO Down Under
  3. 3. Embrace The Differences  Geothermal is hot rocks and energy generation to most  North side of house has greatest solar gain  Split wall units are most common air conditioning systems  Residential usage is on demand not constant temperatures GEO Down Under
  4. 4. Embrace The Differences  32 is a beautiful summers day, 100 is when water boils  50Hz with single phase 240 V or 3 phase 415 V  A ton(ne) is a unit of mass – equivalent to 1000 kg or 2200 lbs  COP is COP is EER  OD is ID: 1” pipe is not 25 mm GEO Down Under
  5. 5. Country Snapshot: Australia GEO Down Under
  6. 6. Country Snapshot: Australia  Land Mass: 7 682 300 sq km  Climate: generally arid to semi-arid, temperate in south and east, tropical in north  Population: 22.2 million  GDP: $987 billion  Per capita GDP: $43 300 per capita  Ground Temperatures: 12 to 32 C  Ambient Temperatures: -15 to 50 C GEO Down Under
  7. 7. Country Snapshot: New Zealand GEO Down Under
  8. 8. Country Snapshot: New Zealand  Land Mass: 267 710 sq km  Climate: Temperate with sharp regional contrasts  Population: 4.4 million  GDP: $134 billion  Per capita GDP: $30 200  Ground Temperatures: 8 to 19 C  Active geothermal areas: >100 C  Ambient Temperatures: -25 to 40C GEO Down Under
  9. 9. History  Early 1990s: First installations  Mid 1990s: Adopted IGSHPA guidelines and training, ISO 9000  1998 to 2006: Acquisition by Utility resulted in years of inactivity  2008: 4 Seasons – Victorian State Government  2012: Standards Development – on hold  2012: Geothermal Heating Association of New Zealand  2013: Australasian GSHPA GEO Down Under
  10. 10. Why the Australasian GSHPA?  IGSHPA guidelines / training been adopted for ~20 years  Critical mass in industry over past two to three years  Protect integrity of local industry  Increase credibility  Collaboration with other industry associations  Formal launch in November 2013  University of Melbourne hosting Piping Design and CGD GEO Down Under
  11. 11. Standards: Existing and Future  Standards Australia and Standards New Zealand  Independent but regularly share common Standards  Common Standard on hold pending international developments  Existing Standards cover:       Water to Air GSHPs Water to water GSHPs (defacto through ISO) PE pipe manufacture (50 year manufacturer warranty) PE fusion Building Code Electrical / plumbing etc  Energy Star does not currently cover GSHPs GEO Down Under
