Measurement in a Prague School

\nIn today’s world, when we don’t want heat to escape from our homes, we seal our doors and windows and thus prevent unnecessary heat and money loss.
\n
\nFresh air is also very important for a healthy and satisfied life. A major current problem in the area of indoor air quality is schools, and that is why we have actively participated together with other partners in the O2 project.

Smart City Project “Environment – Healthy School”

\nThe goal was to monitor the quality of indoor air and assess its impact on the health and attention of students and teachers.
\n
\nThe Smíchov Secondary Industrial School, which provided its premises for the project, is located in a dense urban area and is thus an ideal testing environment.

What are the results?

\nInitially, preliminary measurements were conducted. Air quality sensors were placed in ten selected most burdened classrooms, where the quality of indoor air was continuously monitored and the measured data was transmitted via radio network to the O2 cloud server.
\n
\nThis made it possible to continuously monitor the current state of the environment in the classrooms.
\n
\nIn the provided graph, the measured values are displayed in one classroom in the selected week. According to the regulation of the Ministry of Regional Development, the CO₂ value must not exceed 1,500ppm (parts permillion). From the graph, it is evident that the values of CO₂ concentration in the given week exceeded this limit significantly every school day.

The information obtained will also be used by students

\nThe information from the project is an important tool for analysis aimed at finding optimal solutions for the permanent improvement of indoor environmental quality in schools and beyond. The research and results of this pilot project will also be used by the school in the context of vocational training.
