You can demonstrate a healthy indoor environment with the Indoor Environment Label

The Indoor Climate Label shows at a glance what a building’s indoor climate is like. It also gives building owners the assurance that performance requirements are being met. The Indoor Climate Label does this by assessing four key areas, based on the Healthy Offices Specification: Air, Light, Climate and Noise. Through continuous monitoring and user feedback, you gain insight into your building’s indoor climate.

The Indoor Climate Label is currently suitable for offices, healthcare facilities and childcare centres, but may in future also be suitable for homes and schools. These different types of building often require a different approach, which is why the Indoor Climate Label is currently focused primarily on offices.

Once an Indoor Climate Label has been issued, it is valid for one year. Based on the survey and the continuous monitoring data, the label will be reassessed once this period has expired to determine what it should be. Should the label change on the basis of the new data, it must be updated.

Example:

• 1 January 2026: The building is equipped with all the necessary measuring equipment.
• 1 March 2026: After two months, the building is awarded a provisional Indoor Climate Label C, based on continuous monitoring and a survey.
• 1 January 2027: The final label is issued for the building. In this case, for example, it is once again Indoor Climate Label C. The Indoor Climate Label C for this building is now valid until 1 January 2028.
• 1 January 2028: Based on continuous monitoring throughout 2028 and a new round of feedback via the survey, the Indoor Climate Label is reassessed. In this case, the assessment shows that the new label is an Indoor Climate Label B. This Indoor Climate Label is once again valid for one year, i.e. until 1 January 2029.

The Indoor Climate Label has three types of cost items:

1. One-off investment (via a technology partner)
   • Purchase of measuring equipment: Smart CO₂ and particulate matter monitors that also measure temperature and humidity.
   • Consultancy and installation costs for sensor technology: These depend on the size of the building or room and on the technology partner.
2. Annual software costs for technology partners
   • Software costs: For access to the dashboard and insight into the measurement data. These costs depend on the size of the building or space and on the technology partner.
3. Annual costs for the Indoor Climate Label
   • Basic management costs: For the management and further development of the Indoor Climate Label.
   • Certification fee: For the use of the Indoor Climate Label methodology, including the questionnaire.
   • The annual costs for the Indoor Climate Label are set out in the table below:

Once all the sensors have been installed, a provisional label may be issued after two months. This will be based on the survey and the continuous monitoring data collected over the two-month period. The final label will be issued after one year, as this is when all the monitoring data covering the four seasons will be available. This is particularly important for obtaining an accurate estimate of the temperature.

In addition, the speed of the process depends on a number of different factors. For example, the type and size of the building can influence how quickly your building can be awarded a label. In larger buildings, more measuring equipment needs to be installed, which can take longer. It also depends on how busy the Indoor Climate Label’s partners are. The partners can provide a more detailed estimate of the processing time for your specific building and circumstances.
