Here you will find examples from schools that wanted better control of dirt and moisture in entrance areas and more consistent quality in day-to-day operations. The texts below are taken from previously published material, and quotations are reproduced verbatim.
Bærum Municipality. From five to three days a week with documented quality
In Bærum Municipality, several schools have taken a more systematic approach to cleaning by combining measures in entrance areas with data-driven monitoring. The aim has been to deploy resources where they are actually needed while maintaining consistent quality over time.
The report describes how the cleaning frequency in classrooms can be reduced from five to three days a week without compromising indoor air quality, and how measurements are used to monitor progress and document the results. This provides greater day-to-day predictability, better oversight, and a clearer basis for further improvements across buildings.
Florø Primary School: Data enabled more confident decisions and smoother day-to-day operations
Ahead of a potential merger between Florø Primary School and Krokane Primary School, indoor climate sensors were used to analyze air quality and ventilation capacity. The measurements showed that the school could accommodate an increased number of pupils without compromising the indoor climate, and the data was submitted to the Environmental Health Authority as supporting documentation for approval following the merger.
The analysis revealed that one classroom had 27 students, even though it was designed for 20, and that CO2 levels were too high. The solution was to introduce regular ventilation routines during breaks, which has ensured stable readings below 1,000 ppm, the recommended limit according to the Norwegian Institute of Public Health.
During the 2025 winter break, extensive dust cleaning was planned at the school. Before the work began, the facilities team detected unusually high levels of airborne dust. The source turned out to be the demolition of an old hospital approximately 100 to 150 meters away, with dust entering through the ventilation system. Following discussions between the facilities team, cleaning staff, and contractor, the cleaning was postponed until the demolition work had been completed. This made the cleaning more effective and avoided unnecessary additional work.

Asker Municipality: Permanently installed solution for safer entrance areas
“In addition to trapping dirt and moisture while also being aesthetically pleasing, Renholdssoner has provided us with several other benefits. Because Renholdssoner is a permanently installed matting system, it is also slip-resistant. In schools and kindergartens, where hundreds of children run in and out many times throughout the day, this was an important safety measure for us.”
