Abstract: TITLE: EARTH TUBE COOLING SYSTEM ABSTRACT The present invention relates to an Earth Tube Cooling System designed to provide energy-efficient and sustainable cooling for buildings. The system comprises an underground network of insulated pipes, strategically buried at a depth where the earth maintains a stable temperature. Outside air is drawn through a filtration unit to remove dust and pollutants, then passed through these underground pipes, where it is naturally cooled by the earth's thermal mass. The cooled air is subsequently directed into the building via a ventilation mechanism, reducing reliance on conventional air conditioning systems. This passive cooling technique offers significant energy savings, lowers operational costs, and decreases environmental impact. The system is adaptable to various building sizes and configurations and can be integrated with existing HVAC systems for enhanced efficiency. By harnessing natural underground temperatures, the Earth Tube Cooling System provides an eco-friendly, cost-effective solution for sustainable building climate control
