Prediction method of natural ventilation rate of light well in high rise apartment building.

Author(s) : YAMANAKA T., SATOH R., KOTANI H.

Summary

Light well located in the center of high rise apartment building in Japan is called “Void”. Gas water-heaters settled in Void discharge exhaust gas into Void so that the enough opening area have to be designed at the bottom of Void to keep the IAQ in Void. In order to secure the IAQ in Void, a simple calculation method of ventilation rate induced by wind force and thermal buoyancy through openings at the bottom of Void with heat sources like water heate/s is presented and the accuracy of this calculation method is examined by wind tunnel test. As a result, it is turned out that the simple calculation methods introduced in this study are valid for predicting the vertical temperature distribution in Void and ventilation rate of Void.
