The public health literature indicates that we would expect many co-benefits of increasing ventilation rates
, such as reduced absenteeism due to illness, which has clear impacts on productivity," said Piers MacNaughton, doctoral candidate at the Harvard T.
2013) pointed out that large numbers of residences in European countries have mean ventilation rates
below the requirements of the national building regulations or codes.
The popular theory is that very high ventilation rates
reduce airborne infections.
Another relevant finding was the minimum ventilation rate
during winter resulted to an [NH.
In these studies, the ventilation rate
in an experimental chamber was kept constant at a level producing a chamber C[O.
Application of the carbon dioxide mass balance method to evaluate ventilation rates
in livestock buildings.
The following parameters have a critical influence on the ventilation rates
(the volume of outside air actually introduced into the space): the impairment of the air quality caused by occupants, emissions from materials in the room, activities such as smoking, the quality of outside air, the thermal load (Popa, 2003).
For the exposures in the USPS postal distribution centers, we assumed an exposure time of 8 hours to represent a work shift and a pulmonary ventilation rate
If an indoor air problem is suspected and the problem is beyond the walkthrough phase, the remedy could lie with the building's HVAC system; simply increasing the ventilation rates
may be all that is necessary to correct the situation.
However, he cautions, readers "may easily misinterpret this report as having shown that ventilation rate
is not related to worker symptoms.
Low energy buildings need to be airtight and energy demand for ventilation is often reduced by lowering the ventilation rate
to the minimum necessary.
For child daycare centers accommodated in existing buildings the minimum ventilation rate
has a requirement of 7[dm.
