Coronavirus has been a catalyst for new conversations about air quality in buildings. Â鶹´«Ã½¡¯s Patrick Chambers has an innovative solution that could be as simple as monitoring noise levels.

Air quality within a building is typically maintained by diluting the indoor air with that of outside air. This practice assumes that the outside air is clean ¨C but we know, with growing urban pollution and increasing instances of extreme weather events (such as the ) that this is not always the case.

¡°If instead of being transfixed on increasing dilution rates in buildings, we focussed on exhausting from the point of aerosol release, we could maintain safer base-line levels of indoor pollution/contaminant, without having to significantly increase the quantity of outside air that being processed by the mechanical ventilation system¡±.
