Optimization design strategy of courtyard in hot and humid climate zone

With a multi-story office building in Sanya as the object, studies the influence of the main structural characteristics, bottom overhead model and outdoor environment of the courtyard on the ventilation effect by simulation. The results show that when the length-width ratio is 1∶1, the optimum courtyard depth-width ratio is between 4∶1 and 5∶1, the optimum bottom overhead is unilateral, and the influence of outdoor environment on the temperature within courtyard is weakened with the increase of outdoor air velocity.
