Double Skin Façade Adoption Influencing Ventilation Performance in Educational Buildings

Double skin façades are adaptive envelopes that aim to improve building energy consumption and comfort performance. Their adaptive principle relies on the dynamic management of the cavity's ventilation flow and the shading devices, which can integrate with the environmental systems. This research demonstrates the possibility of modifying existing buildings to study unconventional building envelope solutions. Scenarios A and B show insignificantly decreasing measures in air velocity, relative humidity, and air temperature; however, Scenario C shows the most significant changes, the average air velocity increases by 45%, the air temperature drops between 5 to 8%, and the relative humidity drops between 5 to 8%. The utilization of DSF can be used to reduce solar heat gain, enhance natural ventilation, and mitigate the inefficiencies of mechanical ventilation in educational buildings. The Double Skin Façade is effective in improving parameters that are in accordance with thermal comfort
