· 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.
· The study included 18 classrooms from 17 schools from the north-eastern part of The Netherlands, 12 experimental classrooms and 6 control classrooms. Data on indoor levels of CO2, temperature and relative humidity were collected during three consecutive weeks per school during the heating seasons of 2010–2012. Associations between the intervention and weekly average indoor CO2 …

Classroom-specific ventilation can be a cost-effective solution for indoor air quality issues at schools. Classroom and space-specific ventilation is a cost-effective and quick way to improve the indoor air quality at schools and daycare centres. Humidity, carbon dioxide, and smells caused by people are easy to remove by boosting the ventilation. Also structural impurities can be removed by ...
High indoor CO2 levels mean there is not enough ventilation entering the room. Low CO2 levels indicate over-ventilation. The indoor CO2 reading allows the HVAC system’s outdoor air intakes to modulate based on the building’s actual load. Maintaining the proper indoor CO2 level ensures required ventilation rates are met. CO2-based ventilation control should be applied in: - Classrooms ...

Ten schools (9 elementary, 1 combined middle/high school) in eight New York State school districts were visited over a 4-month period in 2010. Carbon dioxide concentrations were measured in classrooms over 48-h, and teachers completed surveys assessing demographic information and self-reported symptoms experienced during the current school year. Data from 64 classrooms (ranging …
Classroom Management for Middle & High School Based on Love & Logic. At some point in the school year you will have to deal with students that break the rules and challenge authority. And it can be difficult to know how to respond. Approaching situations with an attitude of logic helps you stop and think: What type of response could turn the infraction into a teachable moment or into an outlet ...
Thousands of AirTest CO2 sensors have been installation in school districts throughout the US and Canada. AirTest is known for its zero maintenance, self-calibrating sensor. If you are involved in a school project and would like to talk to another district or contractor who has used AirTest CO2 in their project please contact AirTest at 604 517-3888 to for references. Here is a link to a short video that describes how Siemens in Seattle selected AirTest CO2
Similar to to the carbon dioxide (CO2) research, the results are that once the virus escapes into the classroom you have two choices: Ventilate the building (bring fresh air in from outside) or Remove the virus from the air inside the building (filtration/HVAC systems)
· 5 Common Classroom Management Issues in High School. by Melissa Kruse. Whether you’ve landed your first teaching job, you’ve been in the classroom a few years, or you’re a seasoned veteran, certain classroom management issues rear their ugly heads every year. In this post, read about effective ways to address five of the most common classroom management issues for secondary …
· Because of this, I had zero control over my classroom. I was as helpless as a kitten. In my second year, I overcompensated for my leniency the previous year and behaved somewhat like a dragon. I used procedures this time and had near-perfect control over my classroom, but I was so strict at the beginning of the year that it made it difficult for my students to relate to and/or trust me. Not OK ...
Humidity Control in School Facilities . 2 Humidity Contro l and Comfort The most obvious impact of humidity is comfort. The absolute humidity level (dew point) in our environment impacts perspiration evaporation rate, which helps regulate our body’s energy balance, skin moisture levels and thermal sensation. An excellent reference for the interrelationship between human comfort and humidity ...
· School Classroom CO2 Monitoring CO2 in School Classrooms As reported in a Berkeley Labs study*, high classroom CO2 levels in can significantly impair decision-making performance. This can have a detrimental effect in schools where large amounts of students, ventilation issues and other causes elevate CO2 levels in classrooms and other areas.
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 ...
· During classroom hours the CO2 levels rise but are kept in the 650-750 ppm range because of our increased and constant ventilation throughout the day. Regardless, as mentioned earlier, CO2 levels recorded do not mean a heightened risk of COVID-19, with filtration support added for classrooms that may record higher CO2 levels.
· Ryan Lundell, who has been at East Side Union High School District for the last eight years, thinks the issue of CO2 levels and air quality in classrooms needs to be a priority for schools …
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. The...

Join the leading schools trusting AirGradient. Studies show that students stay 90% of their time indoors and that classrooms often have very high levels of CO2 and in some areas ...
· Schools, hospitals, restaurants, and shops also have high energy requirements and associated high expenses. In total, countries like the spend more than US$400 billion every year on supplying all buildings with energy. They use about 74% of the electricity generated in the , which accounts for about 40% of the country’s total energy expenditure (Figure 5). With effective building ...
Why Monitor CO2 in Classrooms? What do you look for in a school district? Quality of teachers? Reputation? How their sports teams and extra-curricular activities stack up? But, do you ever think about the indoor air quality in the school buildings? In 2014, the National Center for Education Statistics (NCES) surveyed a sample of school districts and estimated the average age of the nation ...
unique conditions we observe in school classrooms and student interest in their environment. Since the monitors are in classrooms they should not be distracting to the goal of the teacher, which is to educate their students. AirWatch is a small esthetically pleasing all-in-one device with easy to read and understand green, amber, and red CO2 parts per million (PPM) level indicators. The ...
· Sometimes, rambunctious high school classrooms need a little longer to comply. In An ELT Notebook article, Rob Johnson recommends that teachers write the following instructions in bold letters on the chalkboard: “If you wish to continue talking during my lesson, I will have to take time off you at break. By the time I’ve written the title on the board you need to be sitting in silence ...
