The odor emission rates in both rooms varied over a large
range (5.6 to 40.2 OU m−2 s−1 for G1, and 1.4 to 15.1 OU m−2
s−1 for G2). There was no apparent seasonal pattern. Although
the temperature was high during the summer, which resulted
in a higher ventilation rate, the odor concentration was low;
therefore, the odor emission rates, which are the product of
the ventilation rate and odor concentration, were not the
highest of the year. Although the ventilation rate was low
during the cold season from November to March, the odor
concentration was high, so it did not result in a lower odor
emission rate.
