Abstract

Indoor air quality and climate of three temporary emergency housing units in Aso City, Kumamoto Prefecture, have been measured from August 2013 continuously and results of the last summer are reported in this paper. Outdoor air was introduced during the daytime, and the average room temperature in the three units was approximately 28 °C. Carbon dioxide concentrations were very high during the evening. Because the outdoor temperature dropped at night, occupants tended to close their windows. A mechanical ventilation system for 24-hour ventilation was installed in the toilet and were typically run, however, the air volume can be insufficient or the route of ventilation can be inappropriate. Concentrations of formaldehyde and volatile organic compounds in the three units were significantly lower than guideline values and fungal contamination was detected in a number of rooms that had less airflow. Good indoor air quality and thermal comfort is required to support victims' health.
