The most influencing factors in this regard are the design and orientation of shedsasthey playvitalrole for energy conservation, heating and cooling distribution with controlled temperature and humidity inside the shed. In this paper, we present detailed preliminary computational fluid dynamics (CFD) analysis of optimized combinations ofopening of ventilation systemsfor different seasonsfor environmentally controlled poultry shed (ECPS) already in use throughout Pakistan.For both dry and evaporative cooling conditions, all vents closed has been determined the optimized combination as air velocities across chickens are observed within acceptable limits of 0.5 m/s. Moreover, evaporative cooling effective temperature of almost 24°C, with relative humidity of 60-70% is observed which is desired for the comfort of chickens in the shed.
