Optimization of Ventilation in Apartments for a Healthy Environment   The COVID-19 pandemic has transformed our way of life, forcing many people to work from home. However, this transition has highlighted the need for an appropriate ventilation rate to ensure a healthy indoor environment. In this context, Faure QEI (Egis Group) has undertaken an innovative project aimed at optimizing the ventilation of apartments.   This innovative project, initiated in collaboration with Professor M. Boulic ofMassey University in Auckland (NZ), APL Window Solutions and Proctor Group Australia Pty Ltd, focused on the ventilation efficiency in a 40-story apartment building in Melbourne.
