Correct Ventilation in Schools Reduces the Risk of Covid-19 Transmission by 80%
The experiment was conducted by the Hume Foundation in the Marche region and compared Covid-19 contagion in 10,441 classes from September 2021 to January 2022.
The Covid-19 pandemic has highlighted to building administrators, such as schools or office buildings, the importance of efficient ventilation in spaces with a high density of people who spend significant time in the same area.
We need a supply of natural air, and this can be achieved through a simple window automation solution, a handy technology that greatly contributes to creating a sense of freedom for beneficiaries.
Chain Motors, the Simple Solution for Window Automation
Chain actuators, also known as chain motors, are probably the most common type of window automation. Very suitable for windows of medium size/weight, chain window automation can be used for ventilation, smoke extraction, or ventilation and smoke extraction in accordance with current legal standards. Chain actuators for windows are the aesthetic, versatile, and economical solution for operating windows for ventilation and/or smoke extraction. They can be integrated into complex BMS systems or controlled by smart control units that operate independently.
According to the study conducted in Italy, Covid infection cases were significantly lower in the 316 classrooms that had mechanical ventilation systems, with even fewer cases where the ventilation systems were more efficient.
With applications that guarantee a complete air exchange in the classroom 2.4 times per hour, infections were reduced by 40%. They were reduced by 66.8% when the air was refreshed 4 times per hour and by 82.5% where this happened 6 times per hour, according to the study.
Mechanical Ventilation in Classrooms, a Positive Impact for Students
Most schools in Italy do not have mechanical ventilation systems. To compensate for this, teachers are advised to keep windows open when the weather permits. The situation is no better in Romania; on the contrary, many schools do not meet the standards for students and teachers to conduct their activities safely. At least the aspect of ventilation could be quickly resolved by automating the windows in classrooms.
If efficient mechanical ventilation systems were installed, it could reduce from 250 cases per 100,000 students (the alert level set by the Italian Ministry of Education) to 50 cases per 100,000, according to the study coordinated by the Hume Foundation and local authorities in the Marche region.
Beyond the major projects that education undoubtedly needs, simple and quick measures can be implemented to improve the experience in schools for both children and teaching staff.
