However, occupancy is often intermittent and unpredictable therefore leading to over-ventilation and energy inefficiencies. Monitoring CO2 levels and automating ventilation to intake air at pre-defined CO2 levels, such as 800ppm, will lead to ventilation when it is actually needed. One study ...

Why Monitor CO2 in Classrooms? -

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a high-level of indoor air quality, is to monitor Carbon Dioxide (CO2) levels within the classroom. Every time you exhale, you release CO2 into the air.

The carbon dioxide -based control identifies when people enter the premises and enhances the efficiency of ventilation almost steplessly. This way, ventilation is not too efficient when there are only a few people present in the classroom but the same room can also be used by large groups. Humidity-based control is the best method to control the efficiency of ventilation in sports facilities ...

Carbon Dioxide on Earth and on the ISS | Let's Talk Science

2019-10-01· Carbon dioxide levels are monitored and controlled on the ISS by the Atmosphere Revitalization (AR) subsystem of the Environmental Control and Life Support System (ECLSS). NASA has set the maximum allowable 24-hour average CO 2 on board the ISS at 5 250 ppm ( mmHg). There are a number of sensors at different places inside the ISS that ...

Sick Classrooms Caused by Rising CO2 Levels

2014-01-13· Carbon dioxide levels in the classroom have been shown to be directly related to a students alertness and ability to concentrate. High levels of carbon dioxide indicate a lack of fresh air intake and that negatively affects the health, attendance rate and learning ability of students. “Increases in indoor CO 2 concentrations… were associated with statistically significant and meaningful ...
