An abstract is a brief summary of a research article in one paragraph, this is the emerging technique which reduce the cooling and heating loads of buildings in winter season and as well as in the summer season. And thus reduce the overall energy consumption in that particular place of installation like buildings, hospitals, schools, colleges etc. It is a geothermal energy (renewable energy). In this system we should focus on the effect of soil characteristics such as moisture content, density of soil, and type of soil on the thermal performance of EAHE system. And the main parameters to be considered in EAHE system is velocity of air, mass flow rate of air, depth of pipe and material of pipe. The effect of the working parameters such as pipe material, pipe length, pipe diameter, depth of burial of the pipe, air flow rate and different types of soils on the thermal performance of Earth-Air Heat-Exchanger (EAHE) systems is very crucial to ensure that thermal comfort can be achieved.
