Ameena Monitoring the Concentration of CO2 in a NYC Classroom

Takahashi Wannikhof, 2001). This project will determine how much CO2 a person is taking in everyday, and how much is surrounding them in the classroom. The CO2 sensor will detect how high the levels of Carbon Dioxide are in the Classroom. If the doors and windows are closed the CO2 levels will increase to levels above 1000pm because all of the air is locked in or the ventilation system is ...

Gratnells Learnometer monitors your classroom environment

“Our research, and others’, confirms that poor light levels, the wrong temperatures, inappropriate sound volumes and rhythms, humidity, air pollution, Co2, and air pressure can all impair learning. Our Learnometer research tool automatically samples your classroom environment, and makes suggestions through a unique algorithm as to what might be changed to allow students to learn and ...

CO2 MONITORING FOR OUTDOOR AIRFLOW AND DEMAND CONTROLLED …

CO2 Monitoring for Outdoor Airflow and DemandControlled Ventilation A number of programs and standards that exist for buildings today specify the use of outdoor air monitoring. Monitoring is to be done either based on CO2levels in the occupied space or actual measurement of outdoor airflow, depending on the space design occupancy and ventilation type (mechanical or natural). Current standards ...

CO2 In the Classroom |

In addition to indoor pollutants, studies also found that carbon dioxide levels rose in sealed classrooms throughout the day. While humans can learn to adapt to high levels of CO2 over long periods (for example, in a submarine) over short periods, even moderate increases in CO2 will result in children who are tired, have headaches or cannot ...

Natural ventilation for schools and classrooms

· Classrooms • Average CO2 concentration in all learning/teaching areas should not exceed 1500 parts per million (PPM) during school hours. • The maximum CO2 concentration should not exceed 5000PPM during school hours. • Occupants must have the means to reduce the CO2 level to 1000PPM with easily accessible controls within each space.

DemandControlled Ventilation (DCV) SVACH

Designers assume that controlling CO2 controls all occupancyrelated pollutants. CO2 sensors are relatively precise, reliable, and inexpensive compared to other types of DCV pollutant sensors. Occupancy sensors count occupants and regulate ventilation airflow accordingly. A major purpose of ventilation systems is to control relative humidity ...

CO2 Dashboards for Ventilation Monitoring in Schools ...

While the project began by looking at the impact of the ARated building on IAQ, and uncovered some serious issues with respect to the CO2 levels in classrooms, it was quickly realised that this method could also be used to monitor and control the ventilation levels in classroom with respect to the spread of COVID19. This has been consolidated recently by John Wenger of the UCC school of ...
