Earlier this autumn, Linköping Science Park reported that AKKR8 and property owner Sankt Kors had initiated tests to measure water leakage in the public bathrooms on the ground floor of Mjärdevi Center and measure the air quality in conference rooms. The tests have now been conducted over 90 days, and the results are here, indicating a few recommendations that could save time and money.
The purpose of the project was to further develop AKKR8’s sensor solution using wireless sensors that utilize BLE technology (Bluetooth Low Energy) to adapt to various buildings. AKKR8’s solution aims to assist companies and organizations to enhance data-driven decision-making in buildings with older systems for collecting measurement data, and the tests are an important part of developing the sensors.
Two separate tests:
- The purpose of subproject 1 is to measure indoor air quality: CO2, TVOC, particle levels, humidity, and temperature in a conference room.
Recommendations for indoor air quality:
The results showed that the measurements indicate a secure air quality situation with occasional elevated levels, but no values reached harmful levels. A recommendation could be to adjust the ventilation during the most intense morning hours to potentially further improve comfort in the room and maintain good air quality.

- The purpose of subproject 2 is to see whether high water consumption in toilets due to leaks can be identified and to map the usage of the toilets.
Recommendations for water consumption in bathrooms:
No water leakage was detected, however insights in usage patterns were identified. Given the stable and low usage, the property owner could consider reducing to a single toilet on this floor, which could lower operating costs while still meeting the needs.

These tests are part of a collaboration with Sankt Kors under the Linköping Climate Neutral 2030 and Viable Cities project. Linköping municipality is supporting small and medium-sized companies by offering test bed vouchers worth 20,000 SEK, encouraging them to trial innovative solutions in the climate and energy sectors. In the long run, some of these tests could be key to creating a more sustainable Linköping.
