CHAPTER 10 G Ventilation Standards in Each Country
The N value showing floor space occupied by one person is calculated by a general rule, and can not be uniformly regulated.
However, the numerical values provided by JIS A3302 (Sewage purification tank management disposal by number of people
calculation table, separated by the intended use of the building) allow some references to be drawn. This N value is created
from the above-mentioned JIS A3302, which was completed for Tokyo, but this table can be treated as a reference for the
entire country.
