Hutt City Council Ground Thermal Piles for Ground Source Heating & Cooling
Tony Sanderson, Principal - Mechanical Engineer from Stephenson & Turner is discussing his work on the recently refurbished Hutt City Council building, which features, for the first time in NZ, a ground source heat pump which uses pipework within the building’s structural piles, known as thermal piles.
The drive to reducing energy consumption and the associated greenhouse gas emissions is now more essential than ever. New technologies are continuously being developed making low-cost alternatives increasingly efficient.
These are a low-cost highly-efficient heating and cooling system which reduces overall energy consumption. There are 60 thermal piles used which go around 15-20 metres below the ground, where the earth temperature is very stable at around 10°C.
