**Note: Ventilation Rate
Ventilation rate represents how much air is introduced into the indoor space
from the outside. Low levels indicate low ventilation rates and potentially
poor air quality. High levels indicate excessive ventilation and potential
excessive energy usage. To obtain an accurate measurement, readings
should be taken 2~3 hours after occupancy has stabilized in a space or
at a peak in daily CO
In indoor air quality control, CO
400ppm (Parts Per Million) is the default CO
(according to ASHRAE: American Society of Heating, Refrigeration and
Air-conditioning Engineers).
