Figure 3: Classroom A – CO2 levels (ppm) after the dashboard was introduced. While the project began by looking at the impact of the A-Rated 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 classrooms with respect to the spread of COVID ...
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.
classroom example. Therefore, the desired differential between indoor and outdoor CO2 concentrations remained constant, too, regardless of how many people actually occupied the zone (Figure 1). By controlling to this constant differential, Cs – Co, CO2-based demand-controlled ventilation maintains the same per-person ventilation rate (Vo) to

• Carbon Dioxide (CO2) based Demand Control Ventilation (DCV) has been in use for over thirty years. • ASHRAE has mandated DCV for classrooms since 1999 • ASHRAE has continually reduced the space density for triggering DCV – 25 people per 1000 square feet 3 . C A L I F O R N I A E N E R G Y C O M M I S S I O N Background • Demand Control Ventilation (DCV) has part of the ...
Indoor Air Quality in Classrooms and COVID19. April 12, 2021. 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 ...
· Sick Classrooms Caused by Rising CO2 Levels. “Exposure to CO2 can result in drowsiness, eye irritation, and inability to concentrate. If a ventilation system provides inadequate fresh-air intake, levels of CO2 in the classroom can rise dramatically during the course of a classroom session.”. Brian W. Smith.
· Once students sense you’re upset, the implication is that you’re lacking control, and that has a snowball effect.

Demand control ventilation (DCV) is required for spaces larger than 500 ft2 and with a design occupancy for ventilation of > 40 people per 1000 ft2 of floor area and served by systems with one or more of the following: a. an air-side economizer, b. automatic modulating control of the outdoor air damper, or c. a design outdoor airflow > 3000 cfm ...
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 ...
