The indoor climate in the Danish public schools is too bad. We have the solution, for schools and municipalities, and we call it INSIDE+

Our unique solution, SKYEN, can now also function as the class's indoor climate monitor with six sensors, dashboard for the class, learning material and municipal solutions for monitoring and reporting.

Documented effectiveness with impressive results

"Our study shows quite clearly that SKYEN, together with a habit kit, supports new sustainable habits in the classroom, which gives students a healthier indoor climate.

When the CO2 level becomes too high, it starts to have a negative impact on the students' well-being and learning. But with the CLOUD, that is actually eliminated.

Here, a year later, there is no indication that the effect is returning. It's pretty crazy."
