| Abstract |
Double-skin facade (DSF) systems offer various opportunities for ventilation and heating. This study developed a multi-story, passive DSF
system for an office building with single-sided ventilation to exploit passive ventialtion and heating in winter. The key design strategies used
for the passive DSF include comparmentalization of cavities, increasedcavity height for the greater preheating effect, while offering individual
control for each room. . EnergyPlus was used for building energy simulation coupled with the airflow-network model. Our results showed that
the increased cavity heights led to the greater airflow and pre-heating effect. The test models helped mitigate the extreme indoor environment
in winter, and the consequent indoor air temperature depended on the dynamics between the ventilation and the preheating effect. |
