Geoexchange is the most energy-efficient, environmentally clean, and cost effective

space conditioning system available (US EPA)

The Evolution of Geoexchange

The Evolution of Geoexchange1912: First patented in Switzerland

1930s: First attempts but little success

1970s: Development of HDPE and first real successes

1980: WaterFurnace first founded

1987:International Ground Source Heat Pump Association (IGSHPA) formed

1988:Technology introduced to Australia

AND NOW........GeoCooling Technology in India in 2010

The Geoexchange Cooling Cycle

Benefits of Geoexchange 1Reduced Energy Costs: 30-70 % savings

Reduced CO2 Emissions and Carbon Credits

Reduced peak electrical loads: 20 to 50 % reductionPower supply mains reducedBack-up energy requirements reduced

Regulator / Rating friendly – both energy and waterUp to 19 points on LEED Rating

Benefits of Geoexchange 2Reduced Maintenance: 20-50 % savings

No cooling tower or boilerEliminates potential for Legionnaires Disease

Longer Life of System:GSHPs – 20 yearsGround Loop – 50 + years

No outdoor equipmentNo dust, salt or pollution damageSafety (no exposed moving parts)Reduced vandalismNo unsightly units on verandahs

Benefits of Geoexchange 3In-built redundancy

If one unit fails client does not lose total space conditioning

Reduced space requirements

Reduced structural requirementsNo cooling towers to be mounted on roofNo requirement for architectural surrounds or noise
