 As health and school officials deal with a second wave of the H1N1
virus, ASHRAE releases
new information on health consequences of exposure to such airborne infectious
diseases and the implications on the design, installation and operation of
HVAC&R systems.
“While the public health view is that influenza transmission occurs
through direct contact or large droplets, newer data suggests it also occurs
through the airborne route, meaning HVAC&R systems may contribute far more
to transmission of the disease and, potentially, to reduction of that same
transmission risk,” said Gordon Holness, president of the American Society of
Heating, Refrigerating and Air-Conditioning Engineering (ASHRAE).
ASHRAE’s Airborne Infectious
Diseases Position Document addresses the impact of ventilation on disease
transmission, the disease for which ventilation is important for either
transmission or control and the control strategies that are available for
implementation in buildings.
