2012-10-17· Schools can benefit in many ways by implementing carbon dioxide monitoring in schools, including better performance of both students and teachers, showing concern for and taking action to optimize student and faculty health, lowering absenteeism rates thereby increases schools funding even optimized ventilation and energy savings.
High CO2 levels in school classrooms continue to be a concern. As a result we reviewed the mass-balance model of ventilation. We identified several factors by fitting the model to the data.

concentration (Co) of carbon dioxide seldom varies by more than 100 ppm from the nominal value.* Because of this and in lieu of installing an outdoor CO2 sensor, most designers use either a one-time reading of the outdoor CO2 concentration at the building site or a conservative value from historical readings. This simplifies control,
Clarkson Controls are Raising Standards in the Classroom for ventilation and C0 2 control to meet new BB101 regulations. The government is getting tough on air quality in the classroom. Under the 2017 BB101 Guidelines maximum CO 2 limits have been reduced significantly and flow rates have been established to include science labs, halls and gyms to ensure children experience a healthy indoor ...
CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...

Sensors Could Control CO2 Levels In Labs. Wednesday 1st August 2018 ...
Carbon dioxide (CO2) is a “sleeper hazard;” very little information outside scientific literature has been published to help facilities understand CO2 health effects and control CO2 exposures. This Carbon Dioxide Safety Program is designed to fill this gap. Breathing concentrations of 30% CO2, even with 70% oxygen, leads to unconsciousness in 30 seconds Your facility may have been doing ...
