Outline of Ventilation Standard for Acceptable Indoor air Quality of Shase, Japan

摘要

The Ventilation Standard HASS-102 of The Society of Heating, Air-Conditioning and Sanitary Engineers of Japan (SHASE Japan) was revised in November, 1997. The title of the revised standard is Ventilation Standard for Acceptable Indoor Air quality. So far, the old Ventilation Standard, which was issued in 1939, had been used for a long time. The task for revision was undertaken by the Sub-Committee on Ventilation Effectiveness and Standard (chaired by Murakami) of SHASE Japan. This paper focuses on the frame work of the Standard, design criteria for acceptable concentration of indoor air pollutants, calculation method for ventilation requirement, technical principles for construction of ventilation equipment and so on.
