Abstract
We applied a simple size-dependent indoor air
quality model to characterize PM10 indoor-outdoor
relationships for wind-induced naturally ventilated
residences in Taiwan region. The natural ventilation
rate was quantified by the opening effectiveness for
sidewall opening (SP) and covered ridge with
sidewall opening (CRSP) type homes. The predicted
PM10 mass indoor/outdoor (I/O) ratios were 0.15 –
0.24 and 0.20 – 0.32, respectively, for SP and CRSP
type homes. Results demonstrate that PM10 I/O
ratios for a wind-induced natural ventilated airspace
depend strongly on the ambient PM size distributions,
building openings design (e.g. height to length ratio
of openings and roof slope), wind speed, wind angle of incidence.
Subjects
