Kinn municipality

Håkon Christensen is an operations technician at Kinn municipality and actively uses the indoor climate sensor from N3 in his daily work. This is to ensure the best possible indoor climate in the various buildings he operates.

Kinn municipality has a strong focus on sustainability and the environment, and wants to be at the forefront of technology at all times to ensure a safe and good indoor climate in its buildings. They therefore use N3's indoor climate sensor as a meter:

- Amount of particulate matter
- Co2
- Relative temperature
- Relative humidity

Håkon and his colleagues at Kinn municipality want a real-time overview of the indoor climate in the various buildings so that they have control. It is also important to be able to see the results of implemented measures. They face different types of challenges in their daily work, and typical examples include

- Optimize ventilation operating times.
- Measure and adjust temperatures to improve the indoor climate in buildings.
- Document the indoor climate in buildings.
- Suggest measures to improve the indoor climate in buildings.

The measures have worked!
By using the indoor climate sensor from N3, they have been able to measure and implement several different measures that have improved the everyday lives of the building users:

Air humidity was improved
One of the buildings received a complaint about dry air. This proved to be true when looking at measurements over time, where the average was as low as 17% and thus below the recommended limit values set by the FHI. The measure was then to adjust the temperature, which was also high in this building. It was adjusted down from 25 degrees to 22 degrees and the humidity went from 17% to 36%.

Poor air in classrooms has been documented and is being improved
A complaint was received about poor air quality in a classroom. The sensor showed that it was above 1200 ppm, which is 20% above the FHI recommendations. The reason for this was that the sensor that controlled the ventilation showed incorrect Co2 and that the air supply was therefore insufficient - which was corrected as soon as Håkon found out.

Bad air in an office building
A complaint was received about poor air quality in an office building and it turned out that the cause was high temperatures due to direct sunlight through windows. Over time, temperatures of up to 28 degrees were measured, which is not optimal. The measure will be external solar shading, which will reduce the temperature and improve the indoor climate for everyone in the building. This is based on concrete and fact-based measurements.

Good and well-functioning collaboration between Operations and Cleaning
Tove Lill Refvik Volle, Head of Cleaning at Kinn Municipality, also uses the N3smart solution for cleaning zones, floor cleaning machines and indoor climate. This gives them good real-time data on when dust removal is needed and contributes to more needs-based cleaning based on good data where the invisible is made visible.

Optimize energy consumption and indoor climate with indoor climate sensor from N3

The rule of thumb says that lowering the temperature by 1 degree can change the energy cost by 5%. Kinn municipality has used N3smart Indoor Air Quality Sensor (IAQ) and reduced electricity consumption by 21% and 26% respectively in two buildings. They have done this while maintaining and documenting a good indoor climate! In other words, it's a win-win situation where you save money while maintaining full control of the indoor climate!

- At a combined primary school and kindergarten, we have delayed the start of ventilation in the morning by one hour and adjusted the fan speed down to 70%. We have been able to document that the air quality is good. In this building, we reduced electricity consumption by 26%.

- In a kindergarten, we have adjusted the fan speed down to 75% and can document good air quality. This reduced power consumption by 21%.

- We will be taking similar measures on several buildings," says Håkon Christensen.

N3's solution has been developed in collaboration with the Norwegian Asthma and Allergy Association.
We at N3 are proud of our collaboration with the Norwegian Asthma and Allergy Association. We are the only sensor supplier to have done this, and together we have developed modern, high-quality sensors that help to improve the indoor climate in all types of buildings.
