Purpose: Although ERV (Energy Recovery Ventilator) is operating during open hours all the time, students tend to be least satisfied with the indoor air quality of library. This discomfort is getting apparently observed while more students have seated longer time. This study aims to measure whether the supplied airflow rate per capita is sufficient against the law-enforced CO₂ concentration - 1,500 ppm in an actual university library. Also this study aims to perform a pilot test of the DCV (Demand Controlled Ventilation) based on number of occupants, as a compensation for the increased airflow rate that could be a recommended reaction after through measuring currently supplied airflow rates. Method: We first have fixed the supplied airflow rates while letting go off entering and leaving students as many as the number of students who usually visit the library, and then measured the marginal number of students at each flowrate, which makes CO₂ concentration under 1,500 ppm. Also we have fixed the 35 students and then measured the desired airflow rate that maintain CO₂ concentration under 1,500 ppm. Lastly, we have tested the occupant-based DCV for the ERV following combinations of the marginal number of students and the desired airflow rates. Result: It is observed that 1) more occupants require larger airflow rates, as expected. It should be noted that when occupants more than a certain number stay in the library, CO₂ concentration is increasing faster than it would do when there is smaller number of occupants; 2) when library is pretty much occupied, the law-enforced ventilation rate per capita may not be sufficient to meet CO₂ concentration under 1,500 ppm; 3) the occupant-based DCV well contains CO₂ concentration under 1,500 ppm upon varied number of occupants, while saving surplus airflow volumes and thus saving the electricity.
