| Abstract |
This field-based study focused on evaluating the thermal performance in building envelope with ventilated cavity, which is set in the internal part of the conventional curtain wall. The fire resistance, the airtightness and the insulation efficiengy were evaluated through mock-up tests. Temperature and air velocity were measured and analyzed by CFD according to the mechanical or natural control of the ventilated cavity. We made a regression model based on the results of this study to predict the rate of temperature drop on the curtain wall with ventilated cavity in summer. |
