There is a growing body of literature that recognizes the importance of Heating, Ventilation and Air Conditioning systems (HVAC) based on ground to air heat exchangers (GAHEs). In the present experimental work, real field experimental setup of GAHEs to study the air quality of GAHE outlet inside a poultry house compared with air ambient and the conventional poultry house (CPH). Results showed that mean air temperature of heat exchanger at the outlet is stable, which remains closer than 24.2 °C, and the average GAHE efficiency is reached 92 % during the experiment period. GAHE maintains an average relative humidity of around 32 % due to the movement and rotation of air stream caused by the fan. GAHE plays a positive role in the ventilation process of the poultry house, as it renews the amount of air inside the poultry room during the study period. One of the more significant findings to emerge from this study is that the Carbon dioxide (CO2) concentration inside the poultry house integrated with geothermal heat exchangers is less than the concentration that exists in conventional one by 400 parts per million (ppm). The application of geothermal energy systems in buildings holds great potential due to its availability, being considered naturally free and sustainability contributions.
