Urban air pollution is rising to alarming levels and the scandal surrounding diesel cars has put airborne health hazards on front pages across the world.
This webinar harnesses the expertise of specialists from CIBSE, ASHRAE and B&ES to examine the role of ventilation, filtration and other engineering services in turning buildings into safe havens from pollution.
Bjarne W. Olesen - Do European standards for indoor air quality take into account outdoor air quality?
Two European standards dealing with the indoor environmental quality is just now going through a detailed revision. In the revision of EN15251, which are dealing with thermal comfort, indoor air quality, illumination and acoustic, is used to estimate the required ventilation rate to provide an acceptable indoor air quality. In general it is assumed that the outside air is clean. However in this standard and especially in revision of EN13779 there are methods included to take into account outdoor air pollutants (particles, ozone and others). Often this is done by a requirement to filtration of the outside air; but also the concept of reducing the amount of outside air by using gas phase air cleaning of the indoor air is presented. The presentation briefly describes the method used in the standards to evaluate the indoor air quality and the influence of outdoor air quality.
