In the wake of the COVID-19 disaster many are calling for a paradigm shift in how citizens and government officials think about the quality of the air we breathe indoors.
This Clean Air Certificate lets you know that those who operate this building are thinking about the air that we breathe in this building.
They have disclosed the ventilation performance of this building so that we all become educated and we never have another indoor infection disaster again.
