Demand Controlled Ventilation (DCV)

20201123· Carbon Dioxide (CO2) sensors are generally used to estimate the occupancy of a space relative to the outside air intake. If the CO2 concentration rises above the operating point, more outside air is needed. Likewise, if the CO2 concentration falls below the operating point, less outside air is needed. The CO2 concentration is a function of the space volume, the number of people, the ...

Indoor Air Quality in Classrooms and COVID19 CO2 Meter

According to ASHRAE, the recommended CO2 level in buildings should be no more than 700 parts per million (ppm) above outdoor air. Since outdoor air is approximately 400ppm, indoor CO2 levels should be no more than 1,100 ppm. Note that this guideline is not designed to limit the amount of CO2, but rather to indicate that a proper level of clean air (1520 CFM/person) is being distributed in ...
