It is a challenge to create the satisfied indoor climate of farm animal housing in hot climate conditions by ventilation design and control. Facing to the global warming tendency, the challenge become event great. To overcome this challenge, an optimal indoor climate control system should be able to cool the ambient air temperature down and enhance the heat removal efficiency from animals. Here, sustainable ventilation techniques integrated with suitable cooling approaches is essential. In published literature, the heat stress effects on animal welfare and production has been addressed. Varied cooling and ventilation techniques have been investigated and reported. In practices, however, different climate regions and farm animal species may request for different engineering solutions. To provide the fundamentals for an optimal design and control of ventilation system with feasible cooling approaches for hot climate farm animal housing, an overview of the available methods and techniques is given and potentials for integrations and optimizations of the methods are discussed.
