the embedded vents in audience area of the stadium have a great number and are uncovered, so have a negative effect on the interior appearance of the building.

Analyses the temperature field and heat gain of advanced Trombe wall separately with five different operation strategies, and determines the better one in which the rolling curtain is pulled down in daytime and rolled up in nighttime, outer vents open for full day, and inner vents open and close automatically.

The problems in the design of the original ventilating system and the influence on the stored-grain were analyzed in this paper,and pointed out the design requirements and the improving plan of the ventilation opening.

Simulates the relation between area ratio of ventilation opening and ventilation quantity with software CFD.

Based on the measurement and analysis, maintains that to obtain favorable natural ventilation effects, the influences of circumjacent buildings and outdoor wind direction be considered when setting air inlets and landform and surface features be rationally applied .
