In Levinthos retreat center is used the geothermal energy which is a method for heating and cooling, a structure using the constant ground temperature.

In reality the Earth is the world’s largest solar collector and at depths of roughly 5 feet below grade the Earth has stored enough energy to maintain about a 50 degree temperature year round.

Geothermal heating and cooling utilizes a ‘ground source’ heat pump to either extract heat from the ground during the winter or reject heat into the ground during the summer.

One of the simplest comparison’s for a geothermal unit is, it is like your refrigerator – in the summer you are standing inside of the refrigerator, and in the winter you are standing in front of the refrigerator – where you usually feel the warm air coming out at the bottom.
