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.
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.
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.
