underground temperatures are usually more constant than temperatures above ground (e.g. in Northern Europe temperatures at 15 metres underground are typically between 8°C and 11°C)Find out more
heat is transferred into or out of the ground via a fluid that circulates in an underground loop of pipesFind out more
heat is transferred between the ground and the building (TABS) using the principle of a vapour-compression cycle to either heat up or cool down the buildingFind out more
TABS (Thermal Active Building Systems)
heat is transferred from or to the rooms of the building via a fluid that circulates in a loop of pipes embedded in the floors, ceilings and/or wallsFind out more
MPC (Model Predictive Control)
to improve the overall efficiency of the hybrid GEOTABS system, an adaptive model predictive control strategy is usedFind out more
GEOTABS, when optimised, are the “perfect marriage” of technology for heating and cooling buildings. “GEO” refers to geothermal heat pumps. “TABS” (thermally activated building systems) include technology like concrete core activation, i.e., pipes embedded in concrete floors through which warm/cold water is pumped to heat/cool a building’s thermal mass. Together, GEOTABS (‘Geothermally Activated Building Systems’) offer tremendous energy savings over conventional systems.
