The concept of underground house air conditioning ventilation tubes got a lot of attention in the early 1980s from architects, builders, and homeowners as an alternative to conventional air conditioning.

Off the grid earth cooling airflow tubes (also known as earth cooling (summer) tubes or earth warming (winter)) are built to blow air through an exchanger providing cooling/heat recovery ventilation. These systems can also function as air-to-soil heat exchanger, earth-air tunnel systems, earth channels, earth canals, ground tube heat exchanger, thermal labyrinths, hypocausts, subsoil heat exchangers, and underground air pipes, among a host of others.
A long underground plastic or metal pipe through which air flows is placed underground. As air moves through this pipe it gives up some heat to the soil before entering your home as cool air.
By the fall of the 20th Century, earth cooling airflow tubes began to receive much attention from builders, architects, and homeowners alike. They have since being regarded as an alternative to conventional air conditioning systems as there are no compressors, and burners or chemicals with only blowers been the only equipment required to move air.
The use of this ventilation system can help buildings or homeowners meet the Passive House standards.
Off the grid earth cooling airflow tubes can be designed in a range ways. One thing most homeowners who fix them fail to realize is that, this type of ventilation system is still poorly understood by many and may still be regarded as experimental. But while adequate performance data is still lacking, there are a number of expert ways to carry out the project of installing off the grid earth cooling airflow tubes. This article is a step-by-step guide to help you.
