Abstract The paper discusses some measured values of penetration into an unoccupied research house in which most of the usual indoor sources of particles are absent, and in which the rate of entry of outdoor particles can be controlled by applied pressure differentials. (NOTE: Several recent studies, indicating significant health risks associated with exposure to fine particles are measured outdoors, have led to increased interest in the relationship between indoor and outdoor fine particles.) Mathematical expressions are developed to compute the characteristic time of response of a building to a change in its environment, such as particle concentration or pressurization. Equations are also presented to compute the particle penetration from measured responses of indoor concentrations to either a pressurization system of air cleaners.
