The objective of ventilation is to maintain the indoor air clean for the occupants.To achieve this in airtight house with mechanical ventilation system, it is essential that the outdoor air is efficiently distributed to each room and contaminants within room are effectively expelled to the outside. Measurement of age of air is useful to identify the outdoor air distribution to each room.However, this method has not enough reliability yet in field measurement.This paper deals with measurement method of age of air in a test house with three different types of ventilation systems, such as mechanical supply and exhaust system with and without return air, and mechanical exhaust system.The purpose of this study is to examine the items as follows : (1) Reproducibility of measurement result. (2) Difference between the step-up and the step-down methods. (3) Influence of infiltration on age of air. (4) Comparison between three different types of ventilation systems.
