Underground concrete space air solar container

Earth tubes – also known as ground-coupled heat exchangers, Canadian well, Provencal well, earth warming tubes, or solar chimneys – are a passive, natural ventilation, low-tech solution for cooling a building in summer and heating it in winter. Earthtubes (earthtubing) are a most highly recommended low-tech, sustainable, non-electric, zero-energy, geothermal passive solar heating and cooling system.
