Room Environment Standard Values
If a central air quality management system or mechanical
ventilation equipment is installed, comply with the standard target
values shown in the table below.
Central air quality management system ventilation capacity and
characteristics
Effective ventilation capacity V 20Af/N (m
3
)
Af: floor space (m
2
), N: floor space occupied by one person
Characteristics: Generally satisfy the table below.
For general ventilation, the effective ventilation area opening is
at least 1/20 of the floor space and the ventilation equipment
installed gives a CO density of 50 ppm and CO
2
density of 5,000
ppm or less. If a central air quality management system or
mechanical ventilation equipment is installed, comply with the
standard target values shown in the table below.
