LoginA new derivation of productivity calculation model based on pollution loads and contaminantremoval effectiveness is applied and the effect of the improved ventilation efficiency onproductivity is estimated. The findings show that the proportion dissatisfied could be asuitable predictor of productivity loss due to indoor air quality in different kinds of officework. The proportion dissatisfied is possible to calculate from olf and decipol units. In a caseof one person per 10 m2 (0.1 olf/m2) and low-emitted material (0.1 olf/m2), the total sensorypollution load is 0.2 olf/m2. If the airflow rate is increased from 0.5 l/s per m2 to 2.0 l/s perm2, it is possible to achieve 7.3% productivity improvement in the thinking task. The effect ofthe contaminant removal effectiveness on the productivity loss could be about 0.5-2%between displacement and mixing systems using the same airflow rate.
