ASHRAE IAQ 2010: Airborne infection controlventilation, IAQ & energy

Abstract

Some key messages that emerged from the conference were: • Continued lack of certainty about the benefits of forced ventilation over natural ventilation, even for infection control. • Lack of quantitative scientific justification for the dilution ventilation rates in our guidance documents. • Knowledge that proximity to an infected person affects infection rate, but the continued lack of certainty about whether that is due to large "ballistic" droplets or just a higher concentration of smaller airborne particles. Besides the papers from the IAQ 2010 conference mentioned above, this special issue also includes an ten additional papers on similar research areas. © 2012 Copyright Taylor and Francis Group, LLC.
