Climate: Why CO2 Is the “Control Knob” for Global Climate ...

· The continuing high rate of atmospheric CO2 increase is particularly worrisome, because the present CO2 level of 390 ppm is far in excess of the 280 ppm that is more typical for the interglacial maximum, and still the atmospheric CO2 control knob is now being turned faster than at any time in the geological record (20). The concern is that we are well past even the 300- to 350-ppm target level ...

On the use of CO2 sensors in schools and other indoor ...

· In environments like schools, monitoring CO2 has added benefits in avoiding increased CO2 levels, which are known to create tiredness in pupils and reduce learning abilities, and have been reported previously as rather prevalent among Swiss classrooms. The benefit of CO2 sensors in schools will thus outlive the pandemic and provide a better learning environment in the long term.

Carbon Dioxide (CO2) Safety Program

Program (a site CO2 Identification and Control Program), the first step in controlling and preventing hazardous levels of carbon dioxide accumulation. Identify operational areas where CO2 can collect, and then develop procedures and methods to ensure that CO2 is dispersed to safe levels. Learn how and when to use all three types of electronic monitors – review your exposures and then decide ...

Control of CO2 in a naturally ventilated classroom ...

The teaching staff and pupils control the ventilation into the classrooms by thermal comfort rather than air quality. Abstract The ventilation performance of a naturally ventilated classroom was investigated to monitor the CO 2 levels and compare compliance with new guidelines. Measurements of CO 2 levels were taken for 1 week during the heating season while different ventilation modes were ...

Control of CO2 in a naturally ventilated classroom ...

The classroom was shown to have adequate ventilation to provide compliance with current recommendations although thermal comfort was sometimes compromised. Trickle ventilation provided useful ventilation at a rate of l s −1 per person. Purge ventilation was shown to reduce the CO 2 concentration by 1000 ppm but would not be sufficient to maintain an acceptable ...

· Purpose To study the effects of a CO2 demand-controlled ventilation system (variable flow) in computer classrooms on perceived air quality and sick building syndrome. Methods University students (27 % women) participated in a blinded study. Two classrooms had variable flow (mean ac/h); two others had constant ventilation flow (mean ac/h). After one week, ventilation conditions …

Why measure CO2 in HVAC applications? |

This device allows occupants to easily monitor and control CO2 levels specific for smart homes, classrooms, offices and commercial buildings. Do note, that outdoor CO2 measurement is not required for LEED credit, and may only be useful under certain scenarios. Companies seeking LEED certification for new buildings should consult a LEED-certified engineer for the most recent rules. Also note ...

Sick Classrooms Caused by Rising CO2 Levels

· The accepted standard CO2 level in a classroom is 1000. That level is easy to maintain when a classroom is empty. Fill the classroom up with a bunch of students and the level of CO2 rises dramatically. That’s because carbon dioxide makes up a part of every breath you exhale causing the levels to rise as more people gather.

Indoor Air Quality in Classrooms and COVID19 - CO2 Meter

The effect of poor indoor air quality in classrooms has been known for years. Chronic illnesses, reduced cognitive abilities, sleepiness, and increased absenteeism have all been attributed to poor IAQ - specifically elevated CO2 levels. What's more concerning today is the effect COVID19 will have on air quality and how will it effect children and schools.

7 Reasons Why You Should Measure CO2 Inside Buildings ...

· 2. CO2 can decrease productivity In the office and classroom, elevated levels of CO2, in the range between 1,000ppm and 2,500ppm, have been found to decrease information utilisation, increase headaches, decrease performance, and increase rates of absenteeism (Satish et al 2012). Generally, CO2 concentrations at 1,000ppm can lead to a statistically significant decrement in decision making performance. CO2 …
