摘要

Provision of good IAQ in buildings located close to a busy road requires application of air filtration systems which are efficient for submicrometer and especially ultra fine particles, since traffic emissions are associated with particles in these size ranges. A study has been conducted in which a filtration system of an office building was designed according to measured outdoor air conditions and theoretically predicted indoor air conditions. The performance of the system was then validated by field measurements of particle concentration levels indoors and outdoors. The two-stage building filtration system consisted of a central outdoor air prefilter unit, and a set of secondary filtration units designated for each floor. The fractional and overall efficiency of each set of filters, as well as the efficiency of prefilter and secondary filtration units was measured in the size range 0.017 ― 0.7 μm. The effect of electrostatic filters on ozone concentration indoors was also investigated.
