Luftforvandling: SKYENs magi i dagtilbud for sundere arbejdsmiljø - Åbn

Air transformation: the magic of SKYEN in day care for a healthier working environment

Vejle Municipality's SKYEN project has transformed the daycare area, created a healthier indoor climate and improved well-being. With 96% of staff actively involved, this is a compelling success story in improving the working environment. Read the full report for details on the project's impressive achievements.

Vejle Municipality's needs

In Vejle Municipality, the day care area faced a challenge in 2022 with a significantly high level of sickness absence.

New research indicates that a major reason for this was due to a sub-optimal indoor climate with elevated CO2 levels. To tackle this problem, the municipality decided to implement SKYEN and related initiatives at four institutions.


  • Establish fixed procedures for effective venting
  • Reduce symptoms associated with high CO2 levels, such as headaches, fatigue and difficulty concentrating
  • Reduce the risk of infection spreading through airborne particles
  • Improve well-being and reduce sickness absence

This initiative represented an exciting journey towards creating a healthier and more productive environment for both children and staff in day care. The case study explored how the implementation of SKYEN and associated measures could lead to significant improvements in the working environment, health and overall well-being at the institutions.


The municipality chose the following products after an in-depth feasibility study and sparring with ÅBN:

The solution was distributed among a total of four institutions in the municipality.


Process evaluation

Throughout the process, the institutions have not only embraced the project, but have dedicated time and energy to ensure optimal success. The heads of the institutions in particular have acted as strong partners and shown an impressive degree of commitment.

Impact evaluation
During the project, a full 96% of the respondents have actively integrated the CLOUD into their daily work routines. These impressive figures are also reflected in significant improvements in staff well-being, sickness absence and general perception of the indoor climate.

Their findings include:

Satisfaction with the indoor climate

An increase from 61% to 77% of the staff are now satisfied with the indoor climate.

In general, the staff has become more disciplined with the ventilation. They do it more frequently and more routinely than before.

This change in behavior has directly contributed to the impressive results that we see here. As a sign of the project's success, fully 70% of the staff would recommend SKYEN to their colleagues in the municipality.

This transformation of the working environment clearly emphasizes the positive impact of the CLOUD on daily life and well-being in the workplace.
