The hot and dry climate of countries with arid and semi-arid zones is the main reason that poul-try products are less available and more expensive than elsewhere. Investing in livestock in these regions requires the use of suitable cooling systems that humidifies the dry air and lowers its temperature. Thermal environment control in poultry houses is greatly recommended to ensure good productivity. In the present work, a cooling solution was proposed with very low energy consumption and that did not use harmful refrigerants, for economic, ecological, and sustain-able farming. It consists of a two-stage indirect/direct evaporative cooling system that reduces the temperature and increases specific humidity to maintain animal comfort conditions inside the poultry house. Biskra City in Algeria with a hot and dry climate was employed as a case study. The evaporative cooling system used the outside air, for air circulation needs in the poultry houses.
