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.
