The concept of personalized ventilation (PV) is at the cutting edge of technologicaldevelopments in the area of air-conditioning and is fundamentally based on improvingventilation to every individual in the built environment. A PV system provides occupants withcontrol so that they can adjust their individual thermal environment as well as achieve goodindoor air quality. Recent studies in Singapore have shown that the use of a PV system inconjunction with a secondary air-conditioning system significantly enhances thermal comfortand IAQ acceptability as well as the perception of freshness in the air. It has been observedthat the use of a PV system tends to lower the average temperature of air in the breathingzone, to which enhanced Perceived Air Quality may be attributable. An interestingpreliminary observation that needs further substantiation is the increased thermal comfort andair movement acceptability at higher draft rating values.
