Summary

NATURAL VENTILATION OF A WALL CAVITY IS AN EFFECTIVE MEASURE TO REDUCE SOLAR HEAT PENETRATION THROUGH A BUILDING ENVELOPE INTO THE INDOOR ENVIRONMENT. A NUMERICAL SIMULATION MODEL WAS COMPOSED TO DISCUSS THE EFFECT OF THE CAVITY VENTILATION ON THE HEAT PENETRATION REDUCTION. THE PERFORMANCE OF THE SIMULATION WAS EXAMINED BY COMPARING ITS RESULTS WITH THE EXPERIMENTAL RESULTS OF THE WEATHER EXPOSED MODELS OF A CAVITY WALL. THE SIMULATION METHOD INDICATED GOOD AGREEMENT OF TEMPERATURE CHANGE IN THE CONCRETE PLATE WITH THE EXPERIMENTAL RESULTS AND SEEMED TO BE SATISFACTORY TO EXAMINE THE EFFECT OF CAVITY VENTILATION ON THE THERMAL PERFORMANCE OF CAVITY WALLS UNDER VARIOUS CLIMATIC CONDITIONS.
