Heating and cooling buildings is a basic necessity for modern life but is a hugely energy intensive process. The GeoTerre Geothermic Wall is a new type of surface geothermal probe offering cheap and low emission cooling and heating buildings. The Solution is compact, fast and easy to install with a small digger for free cooling and heating. It uses the ground temperature at 2-5 metres below ground where temperatures are mostly constant all over the year. For locations where the average yearly temperature is less than 16°c, the Solution can provide cooling during summer without using HVAC or traditional air-con system. The GeoTerre Geothermic Wall reduces complete cost of ownership, has a 100 year life time, has nearly no running costs and installation costs which are nearly the same as HVACs. This Solution can help eliminate the heat island caused by HVACs, and can deliver a 90% CO2 emission reduction compared to HVAC. It can be used in a wide range of contexts, including houses, small buildings, schools, colleges, small medic centers, small server rooms.
