How do you get a healthy indoor climate?
The challenge in schools and offices
When indoor climate is based on nature's own solutions
We humans thrive best in fresh air, daylight and peace. Yet we spend up to 90% of our time indoors – often in rooms with heavy air and artificial light.
With ÅBN, we bring nature's most important principles into the classroom and office. The result? Better concentration, greater well-being and more energy in everyday life.

OPEN the nature inside
When the air gets heavy, everything else sinks
In schools and workplaces, the indoor climate is often overlooked – but the consequences are clear:
- 1 million Danes experience bad air at work every week
- 6 out of 10 classrooms have too high CO₂ levels
- Poor indoor climate costs billions in sick leave and lost productivity
- One child's lost concentration can be equivalent to 18 school days
If we want a healthy welfare society, we must take the air seriously.


The solution is technology that turns data into action
SKYEN is a Danish sensor that visualizes indoor climate with light and data.
Red light when air is bad – blue when airing out.
🎓 At school: Students learn to act on the indoor climate
🏢 At the office: More energy and fewer distractions
🏛 In the municipality: Decisions based on data, not feelings
Data that makes a difference
SKYEN sends its measurements directly to ÅBN's digital platform, where you can:
📊 See real-time indoor climate data in all rooms
🟢 Get the A–G rating you know from the energy label
📥 Export data to Excel, API or your operating system
👩💻 Create insight and arguments for change
With our platform, you don't just get measurements – you get meaning .


We make it possible to feel nature even when you are indoors.
When we create better air, we create better lives.
With ÅBN you get a solution that is as simple as it is necessary.
It's not about building new things – but about making the best of what we already have.
